Return on equity (ROE) measures the profit a development returns against the cash you actually put in, not against what the project cost to build. If a scheme clears $3 million in profit on $7 million of equity, the return on equity (ROE) is roughly 43 per cent over the life of the project. That is the number equity partners judge you on, because it answers the only question their capital cares about: for every dollar contributed, how many dollars came back.
Return on equity (ROE) is also the metric most often confused with margin on cost, and the two pull apart the moment you add debt. Add gearing and your margin on cost falls, because interest adds to the cost base, while your return on equity (ROE) climbs, because a smaller slice of equity is carrying the same profit. This guide sets out how to calculate return on equity (ROE) on a development, why gearing pushes it above your margin on cost, what a workable number looks like in the current Australian market, how tax and state costs move it, and where the metric quietly flatters a deal.
All figures below are in Australian dollars unless a section states otherwise, and every number in a worked example is illustrative. Your own deal will differ.
What is return on equity (ROE) in property development?
Return on equity (ROE) in property development is the profit a project returns divided by the equity invested to fund it, expressed as a percentage. In its simplest form for a build-to-sell scheme:
Return on equity (ROE) = Net project profit ÷ Total equity invested × 100
Net project profit here is what is left after every cost, including land, construction, professional fees, holding costs and finance interest, and after tax if you are measuring a post-tax return. Total equity invested is the cash the developer and any equity partners actually contribute, as opposed to the money borrowed from a lender.
This is the developer’s version of a metric that carries at least three other meanings, and the Australian search results mix them all together. It helps to separate them, because they answer different questions.
The corporate version, the one Investopedia defines as return on equity, divides a company’s annual net income by shareholders’ equity on the balance sheet. It measures how hard a listed company works its retained capital, year after year. Useful for judging a builder or a listed developer as a business, less useful for judging a single project.
The rental or hold version divides the annual net cash flow of a standing asset by the equity currently sitting in it. This is the number a landlord uses to decide whether to refinance or sell, and it is what most of the “return on equity” pages ranking in Australia actually describe. It is close to the cash-on-cash return, which measures annual pre-tax cash flow against the cash invested. Neither is the right tool for a development, because a development does not throw off steady annual cash flow. It absorbs cash for two or three years, then returns it in a lump on settlement.
The development version, the subject of this guide, measures the return over the life of a project: total profit against total equity contributed, from the first deposit to the final settlement. It is the number equity partners price their money against, over the life of the deal. When a developer, a financier or a joint-venture partner asks “what’s the return on equity”, in a development context they almost always mean this.
How do you calculate return on equity (ROE) on a development?
Start with the profit, then divide by the equity that produced it. The mechanics are simple; the care is all in what you include on each side of the line.
Take a small residual-land-value deal with no debt, so the metric is clean:
- Net revenue (sales, after selling costs and Goods and Services Tax): $24,000,000
- Total development cost (land, construction, professional fees, holding costs): $20,000,000
- Net profit: $4,000,000
- Equity invested (the whole cost, since there is no debt): $20,000,000
- Return on equity (ROE) = $4,000,000 ÷ $20,000,000 × 100 = 20 per cent
With no gearing, the return on equity (ROE) equals the margin on cost. That is not a coincidence. When equity funds the entire cost base and there is no interest to pay, the two ratios share the same numerator and the same denominator. This is the anchor to remember: ungeared, return on equity (ROE) and margin on cost are the same number. Everything interesting about the metric happens once debt enters.
Three things determine whether your calculation is honest.
Count all the equity, including the cash that goes in early. Equity is not only the headline contribution. It is the land deposit paid at exchange, the acquisition costs, the pre-construction spend on design and approvals, and often the interest that is serviced rather than capitalised. Money that goes in eighteen months before a lender draws a dollar is still equity at risk, and leaving it out overstates the return.
Decide whether you are measuring pre-tax or post-tax, and label it. A pre-tax return on equity (ROE) of 40 per cent can become a post-tax return closer to 28 to 30 per cent once company tax is paid, and the gap is wider again for an individual on the top marginal rate. Most equity partners want to see both, but they will not accept a pre-tax number dressed up as the real return. More on the tax drag below.
State the period, and consider annualising. A return on equity (ROE) of 43 per cent means very little until you know whether it was earned over eighteen months or four years. A total-project return of 43 per cent over two years is an equity multiple of about 1.43 times, which annualises to roughly 20 per cent per year. The same 43 per cent stretched over four years is closer to 9 per cent per year, a different proposition entirely. Quoting the total figure without the timeframe is the most common way return on equity (ROE) gets used to make a slow deal look fast.
Why does gearing make return on equity (ROE) diverge from margin on cost?
Gearing pushes return on equity (ROE) above margin on cost because debt shrinks the equity base faster than interest shrinks the profit, as long as the project earns more than the debt costs. This divergence is the single most important thing to understand about the metric, and it is why margin on cost and return on equity (ROE) answer different questions on the same deal.
Take the same $24,000,000 project, now geared at a loan to cost ratio of about 65 per cent.
The upside: how debt lifts return on equity (ROE)
Debt lifts return on equity (ROE) by replacing expensive equity with cheaper borrowed money, leaving the profit to be shared across a smaller equity base. Here is the same deal with a lender in the stack:
- Pre-finance development cost: $20,000,000
- Senior debt (about 65 per cent of cost): $13,000,000
- Equity contributed: $7,000,000
- Capitalised interest over the build (illustrative, at a senior rate of roughly 8.5 per cent per annum on a progressively drawn facility): about $1,000,000
- Total cost including finance: $21,000,000
- Net revenue: $24,000,000
- Net profit: $3,000,000
Now look at what happens to the two metrics side by side:
- Margin on cost: $3,000,000 ÷ $21,000,000 = 14.3 per cent (down from 20 per cent, because interest added $1,000,000 of cost)
- Return on equity (ROE): $3,000,000 ÷ $7,000,000 = 42.9 per cent (up from 20 per cent, because equity fell from $20,000,000 to $7,000,000)
The margin on cost fell and the return on equity (ROE) more than doubled, on the same site, the same build and the same sale prices. Nothing about the physical project changed. All that changed was the funding mix. This is the mechanism behind gearing: borrowing at a cost below the project’s return transfers the surplus to equity, and the thinner the equity, the larger that surplus looks as a percentage.
Push the gearing higher, say by adding mezzanine finance to take total debt toward 80 per cent of cost, and the effect compounds again. Equity might fall to around $4,200,000, and even after the mezzanine’s higher coupon eats into profit, the return on equity (ROE) on the remaining sliver of equity can climb past 50 per cent. On paper it looks like a better deal. It is not necessarily a safer one.
The downside: how debt amplifies a loss
The same gearing that lifts return on equity (ROE) in a good market amplifies the loss in a bad one, and it can turn a thin profit into negative equity. Gearing does not add return; it magnifies whatever the project does, in both directions.
Take the geared deal above and assume revenue falls 15 per cent, from $24,000,000 to $20,400,000, with costs holding at $21,000,000:
- Ungeared version (equity $20,000,000, no interest, cost $20,000,000): profit $400,000, return on equity (ROE) +2 per cent. Thin, but still positive.
- Geared version (equity $7,000,000, cost including interest $21,000,000): loss of $600,000, return on equity (ROE) −8.6 per cent. The equity holders are underwater.
A 15 per cent fall in revenue barely dents the ungeared return but wipes out the geared one and eats into capital. In practice the geared downside is worse still, because a soft market usually lengthens the sell-down, which increases holding costs and capitalised interest, dragging the return on equity (ROE) down further. This is why a headline return on equity (ROE) should always be read alongside the gearing that produced it. A 45 per cent return on 20 per cent equity is a very different risk to a 25 per cent return on 40 per cent equity, even though the first number looks more attractive.
Return on equity (ROE), margin on cost and return on cost: which does what?
Return on equity (ROE), margin on cost and return on cost are three profit ratios with three different denominators, and each answers a distinct question. Confusing them is one of the most common sources of argument in a feasibility review.
- Margin on cost divides profit by total cost. It answers “how fat is the profit relative to what it took to build”. Australian lenders and valuers lean on this one, and a margin on cost of around 20 per cent is the conventional benchmark a financier likes to see on a build-to-sell scheme before committing, a figure consistent with the hypothetical-development approach used by the Australian Property Institute. Our margin on cost versus revenue guide walks through the conversion maths and which number lenders expect.
- Margin on revenue divides profit by total revenue, or gross realisation value. It answers “how much of each sales dollar is profit”. It is always a smaller number than margin on cost for the same deal, and it is the basis used for a target-margin residual land value calculation.
- Return on cost divides profit by total cost as well, and in most Australian usage it is treated as a synonym for margin on cost. It measures the project’s efficiency, independent of how it is funded.
- Return on equity (ROE) divides profit by equity. It answers “how hard did my cash work”, and unlike the other three it moves with the funding structure, not just the project.
The clean way to hold them apart: margin on cost and return on cost describe the project, and are blind to funding. Return on equity (ROE) describes the capital, and is shaped by funding. A single scheme can carry a modest 15 per cent margin on cost and a strong 40 per cent return on equity (ROE) at the same time, and both numbers are correct. Keeping all of them in view together, margin on cost, margin on revenue, return on cost, internal rate of return (IRR) and return on equity (ROE), is what stops the project view and the equity view being read as the same thing.
Return on equity (ROE) versus internal rate of return (IRR): why partners look at both
Return on equity (ROE) tells you how much your equity earned; the internal rate of return (IRR) tells you how fast. Equity partners look at both because neither is complete on its own, and a deal can look strong on one and weak on the other.
Return on equity (ROE) is a total, static figure. It compares all the profit to all the equity, and in its basic form it ignores when each dollar went in and came out. A project that returns 43 per cent over two years and one that returns 43 per cent over four years show the same return on equity (ROE), even though the first is plainly the better use of capital.
The internal rate of return (IRR) fixes exactly this blind spot. It is the annualised return that accounts for the timing of every cashflow, so early capital returned is worth more than the same dollars returned late. Two deals with an identical return on equity (ROE) can have very different internal rates of return (IRR) once you weigh the timing: staged settlements that return equity progressively will beat a single settlement at the end, even for the same total profit.
The trade-off runs the other way too. The internal rate of return (IRR) can be engineered to look spectacular on a short, tightly geared deal while the absolute dollars stay small, and it tells you nothing about the size of the cheque at the end. Return on equity (ROE) and profit in dollars keep that honest. A sensible read uses all three together: return on equity (ROE) for the multiple on your cash, the internal rate of return (IRR) for the speed, and profit in dollars for the size.
What counts as a good return on equity (ROE) for an Australian development?
There is no single “good” number, but Australian equity investors in development typically look for a return well into the double digits to compensate for the risk, and what counts as acceptable moves with gearing, presale cover and where the site sits. A return on equity (ROE) that would be strong for a low-risk, pre-sold townhouse project could be thin for a speculative apartment tower with no cover.
As a rough guide to how the market prices development equity in the current cycle:
- Preferred equity, which sits ahead of the developer’s ordinary equity and takes a fixed return, has generally been priced at around 10 to 14 per cent per annum in early 2026 for the harder, more secured structures.
- Blended or “soft” preferred equity that shares in the upside has tended to target total returns in the mid-to-high teens, often framed as a 14 to 18 per cent internal rate of return (IRR).
- Ordinary developer equity, which takes the residual after everyone else is paid and carries the most risk, needs to earn more again to be worth doing, which is why developers often look for a project-life return on equity (ROE) north of 30 to 40 per cent on a geared build-to-sell scheme, equivalent to a meaningfully lower annualised figure once you spread it over the build.
These ranges are indicative, not rules, and they move with the cost of debt. In a higher-rate environment, senior debt is dearer, so the surplus available to equity is thinner and the required return on equity (ROE) rises to compensate. You can check the current setting against the Reserve Bank of Australia cash rate, which anchors the base cost of borrowing. The lending environment matters too: with the banking regulator, the Australian Prudential Regulation Authority, holding banks to tighter capital settings through the cycle, senior gearing has been harder to stretch, which pushes more of the stack onto equity and mezzanine and changes the returns each layer demands.
Two forces move the required number the most. Higher senior gearing means a thinner equity buffer and more risk, so equity demands a higher return on equity (ROE). Stronger presale cover reduces sell-down risk, so partners will accept a lower return on equity (ROE) for the same project. A number only means something once you know the gearing and the presale position behind it.
How does the equity waterfall split return on equity (ROE) between partners?
On a deal with more than one equity source, there is no single return on equity (ROE). Each partner earns their own, set by where they sit in the equity waterfall and what share of the profit they negotiated. The project has one profit; the waterfall decides who gets what slice, and therefore what return each dollar of capital earns.
In a typical structure, preferred equity recovers its capital and takes its fixed return first, ordinary equity recovers its capital next, and the residual profit is split between the developer and the investors, often with the developer taking an outsized “promote” share once a hurdle is cleared. The result is that the same project can hand a preferred investor a steady 12 per cent while the developer’s ordinary equity earns 60 per cent or loses money, depending on how the deal performs against the hurdles.
This is worth understanding before you raise a dollar, because the return on equity (ROE) you quote to an investor is not the project’s return; it is that investor’s slice of it. A model that runs the profit through the waterfall can report a separate return on equity (ROE) for each equity source, its share of the distributions less its capital contribution, over that contribution, which is the number each investor actually earns. Our equity waterfall guide sets out the return-of-capital, preferred-return, catch-up and promote tiers in detail.
How does tax change your return on equity (ROE)?
Tax generally turns a pre-tax return on equity (ROE) into a materially lower post-tax one, and for most developments the drag is larger than people expect, because development profit is usually taxed as ordinary income rather than as a discounted capital gain. Quoting a pre-tax return to an equity partner without saying so overstates what they will actually keep.
The starting point is how the profit is characterised. The Australian Taxation Office (ATO) treats profit from a development undertaken to make a profit as ordinary income, not a capital gain. Its long-standing view in Taxation Ruling TR 92/3 is that a profit from an isolated commercial transaction is assessable income where the property was acquired with a purpose of profit-making by the means that produced the profit. Guidance from the Australian Taxation Office (ATO) on the tax consequences of selling property sets out the same revenue-versus-capital line. The practical consequence for return on equity (ROE) is important: because a typical build-to-sell development is on revenue account, the 50 per cent capital gains tax discount generally does not apply, so the full profit is taxed. Developers who assume they will halve their tax bill the way a long-term investor might are usually mistaken.
The rate then depends on the structure holding the project:
- A company pays tax at 30 per cent, or 25 per cent if it is a base rate entity with aggregated turnover under $50 million and no more than 80 per cent passive income, per the Australian Taxation Office (ATO) company tax rates for 2025-26. A pre-tax return on equity (ROE) of 43 per cent becomes roughly 30 to 32 per cent post-tax in a company at the 25 to 30 per cent rate, before considering what happens on distribution.
- An individual or a trust distributing to individuals is taxed at marginal rates up to 47 per cent including the Medicare levy, which can cut the post-tax return on equity (ROE) further, though the profit is not usually eligible for the capital gains tax discount when the activity is a development.
The Goods and Services Tax margin scheme also touches the return, because it can reduce the Goods and Services Tax payable on new residential sales and therefore lift net revenue and the profit that flows to equity, provided the eligibility conditions are met and the parties agree in writing before settlement. Modelling the margin scheme properly, rather than assuming a flat Goods and Services Tax figure, keeps the post-tax profit, and the return on equity (ROE) that depends on it, closer to reality.
One change worth watching. From 1 July 2027, the federal government has announced that the 50 per cent capital gains tax discount will be replaced for individuals, trusts and partnerships by cost-base indexation plus a minimum tax on net capital gains, as summarised by Baker McKenzie. For pure trading developments the discount was rarely available anyway, so the direct effect on most developers may be limited, but anyone relying on capital treatment for a build-to-hold exit should confirm the position before it takes effect. None of this is tax advice; the treatment of your project turns on its facts, and it is worth confirming with your accountant.
How do state and territory differences move your return on equity (ROE)?
Return on equity (ROE) does not vary by state as a formula, but the equity base it divides into does, because the cost of acquiring and holding land differs across the country. Two identical buildings, one in New South Wales and one in Queensland, can tie up different amounts of equity for different lengths of time, which is enough to move the return.
The two levers are acquisition duty and holding costs. Transfer duty (stamp duty) on the site is usually funded from equity at settlement, so a higher duty bill means more equity locked in from day one, dragging the return on equity (ROE) down. Land tax and other holding costs accrue while you hold the site through planning and construction, and the longer and dearer that hold, the more equity it consumes. Both differ markedly by jurisdiction, so the same deal produces a different equity number depending on where it sits.
- In New South Wales, land tax is administered by Revenue NSW and applies above a threshold on the aggregated taxable value of land held at 31 December each year, with a premium rate above a higher threshold. A long hold on a high-value inner-city site can add meaningfully to the equity tied up.
- In Victoria, land tax is administered by the State Revenue Office Victoria and applies from a lower threshold than New South Wales, so a Victorian site of similar value can carry a larger annual holding cost, with the difference funded from equity across the project.
- In Queensland, land tax is administered by the Queensland Revenue Office, with its own thresholds and rates, and duty and holding settings that again change the equity number.
- The smaller states and territories, South Australia, Western Australia, Tasmania, the Australian Capital Territory and the Northern Territory, each run their own duty and land tax regimes. The Australian Capital Territory is the outlier, having largely replaced transfer duty with higher general rates over a phased transition, which shifts more of the cost into the annual hold than the upfront purchase.
The point for return on equity (ROE) is not the detail of each regime; it is that the state you build in sets how much equity you commit and for how long. Carry your accountant’s or conveyancer’s duty and land tax figures into the feasibility as cost lines, and the return on equity (ROE) will reflect the real equity commitment for that jurisdiction.
How does return on equity (ROE) work for New Zealand developers?
Return on equity (ROE) works exactly the same way for a New Zealand (NZ) development, profit over equity invested, but the tax and cost inputs that feed it differ, so the post-tax number lands differently. Two features stand out for New Zealand (NZ) developers.
First, there is no general capital gains tax and no stamp duty in New Zealand (NZ), which changes the equity base and the after-tax return. The absence of transfer duty means less equity is consumed at acquisition than on a comparable Australian site, which, all else equal, supports a higher return on equity (ROE). But development profit is still taxable. Under the land sale rules in the Income Tax Act 2007, profit from land acquired with a purpose or intention of resale, or by a person in the business of developing or dealing in land, is taxed as income at marginal rates up to 39 per cent, as Inland Revenue explains for buying and selling property. The bright-line test, reset to a two-year period for residential property sold from 1 July 2024, can also tax a gain on a short hold, though the broader land sale rules usually catch a genuine development regardless of the bright-line period.
Second, the Goods and Services Tax rate is 15 per cent in New Zealand (NZ) rather than 10 per cent, which changes net revenue and therefore the profit that reaches equity. New Zealand (NZ) does not have an equivalent of the Australian margin scheme, so the Goods and Services Tax treatment of a New Zealand (NZ) development follows different rules, and the net-of-tax revenue that drives the return on equity (ROE) should be modelled on the New Zealand (NZ) basis, not the Australian one.
The metric travels across the Tasman without change. The inputs do not, so a return on equity (ROE) built on Australian tax and cost assumptions should not be read straight across to a New Zealand (NZ) deal.
How should you model return on equity (ROE) in a feasibility?
Model return on equity (ROE) from a proper cashflow, not a single line, because the number depends on how much equity goes in and when, and a static calculation misses both. The honest version comes out of a month-by-month model that tracks equity draws, debt draws, interest and the eventual return of capital and profit.
A few habits keep the number reliable:
- Fund the model in the right order. Equity usually goes in first, before the lender draws, so the early deposit, acquisition costs and pre-construction spend all sit on equity. If your model draws debt from day one, it understates the equity at risk and overstates the return on equity (ROE). A funding waterfall that allocates costs to senior debt, then mezzanine, then equity in the right sequence gets this right.
- Stress the return on equity (ROE), do not just point-estimate it. Because gearing amplifies both directions, a small move in revenue or cost swings the geared return on equity (ROE) hard. Run the metric across a sensitivity grid, softening revenue and inflating cost, so you can see how quickly the return on equity (ROE) turns negative. A deal that shows 45 per cent in the base case and negative equity at minus 10 per cent revenue is a different risk to one that holds up.
- Separate the project return from the equity return. Keep margin on cost and return on cost in view alongside return on equity (ROE), so you can tell whether a strong return on equity (ROE) reflects a genuinely good project or just aggressive gearing on a thin one.
A feasibility platform such as Feasly builds this from the funding stack up: modelling senior, mezzanine, preferred and ordinary equity, capitalising interest, and reporting the return on equity (ROE) alongside the internal rate of return (IRR), net present value (NPV) and margin. That lets you see the project view and the equity view of the same deal, and stress both, without maintaining a parallel spreadsheet.
Where does return on equity (ROE) mislead developers?
Return on equity (ROE) misleads most often when it is read on its own, because a high number can come from a genuinely strong project or from dangerously thin equity, and the metric alone cannot tell you which. Four traps recur.
It rewards gearing indiscriminately. As the worked examples showed, adding debt lifts return on equity (ROE) whenever the project earns more than the debt costs, so the metric climbs even as the deal gets riskier. A 55 per cent return on equity (ROE) on 15 per cent equity is not obviously better than a 35 per cent return on 35 per cent equity; it is more geared, and more exposed to a soft market. Always read the return on equity (ROE) next to the gearing.
It ignores timing in its basic form. Two deals with the same return on equity (ROE) can be worlds apart if one returns capital in eighteen months and the other in four years. That is what the internal rate of return (IRR) is for, and why partners rarely rely on return on equity (ROE) alone.
It says nothing about absolute dollars. A tightly geared small deal can show a huge return on equity (ROE) on a modest profit. A large, lightly geared project can show a lower return on equity (ROE) on a far bigger cheque. The percentage does not pay your overheads; the dollars do.
The equity figure can be gamed. Because the denominator is equity, a developer can flatter the return on equity (ROE) by leaving early equity, holding costs or interest funded from equity out of the count, or by using a snapshot equity figure rather than the true cash invested over the life of the deal. When you review someone else’s return on equity (ROE), the first question is always what sits in the denominator.
Frequently asked questions
Is return on equity (ROE) the same as return on investment (ROI)? No. Return on investment (ROI) usually measures profit against the total capital deployed, debt and equity together, while return on equity (ROE) measures profit against equity alone. On an ungeared deal they are close; the more debt in the stack, the further apart they move, with return on equity (ROE) sitting above return on investment (ROI).
What is a good return on equity (ROE) for a property development? It depends on the risk and the gearing, but ordinary developer equity on a geared build-to-sell scheme often targets a project-life return on equity (ROE) above 30 to 40 per cent, while preferred equity may accept 10 to 14 per cent per annum for taking less risk. A number only means something once you know the gearing, the timeframe and the presale cover behind it.
Does return on equity (ROE) include tax? It can be measured either way, so always label it. A pre-tax return on equity (ROE) ignores the tax the profit will attract, and because development profit is usually taxed as ordinary income rather than a discounted capital gain, the post-tax return can be materially lower. Equity partners generally want to see the post-tax figure.
Is the internal rate of return (IRR) better than return on equity (ROE)? Neither is better; they answer different questions. Return on equity (ROE) gives the total multiple on your cash, and the internal rate of return (IRR) gives the annualised return that accounts for timing. Read together with profit in dollars, they give a fuller picture than any one alone.
How is return on equity (ROE) different from cash-on-cash return? Cash-on-cash return measures a standing asset’s annual cash flow against the cash invested, which suits a rental hold. A development does not produce steady annual cash flow, so its return on equity (ROE) is measured over the life of the project, from first deposit to final settlement, not year by year.
The bottom line for developers
Return on equity (ROE) is the return your capital earns, and it is the number your equity partners price their money against, which is why it deserves as much attention as your margin on cost. The two are the same on an ungeared deal and pull apart the moment you add debt: margin on cost falls as interest adds to the cost base, and return on equity (ROE) climbs as a thinner equity slice carries the profit. That divergence is the point of the metric, and also its main risk, because the same gearing that lifts the return in a good market amplifies the loss in a bad one.
Used well, return on equity (ROE) sits alongside margin on cost, the internal rate of return (IRR) and profit in dollars, each covering the others’ blind spots: the project view, the equity view, the speed and the size. Used badly, on its own, it rewards gearing and flatters thin equity. Model it from a real cashflow, count all the equity that goes in, label it pre-tax or post-tax, and always read it next to the gearing that produced it. Do that, and return on equity (ROE) becomes one of the most useful numbers on your feasibility rather than one of the easiest to misread.
