A real estate development proforma is a forward-looking financial model that projects a project’s costs, financing, revenue and returns, from land purchase through sale or stabilization. It helps a developer test whether a project meets its return requirements and how much the team can afford to pay for land.
The terms proforma and pro forma mean the same thing.

What goes into a development proforma?
A development model depends on both amounts and timing. Construction costs usually arrive before sales or rental income, so the cash flow determines funding needs and interest carry.
Inputs
- Land: purchase price, acquisition costs and taxes.
- Hard costs: construction, site work and contingency.
- Soft costs: design, permits, professional fees, legal, marketing and developer fees.
- Financing: equity, loan facilities, interest rates, fees, draw schedules and repayment timing.
- Revenue: unit mix, sales prices or rents, absorption, lease-up and exit assumptions.
- Timing: acquisition, construction, completion, sales, stabilization and exit.
Outputs
- Total development cost, funding needs and peak debt.
- Development profit, profit on cost and profit margin.
- Internal rate of return (IRR) and equity multiple, where equity cash flows are modeled.
- Residual land value: the amount available for land after costs, financing and the required return.
Development proforma vs. stabilized property proforma
| Question | Development proforma | Stabilized property proforma |
|---|---|---|
| Main decision | Should we build, and what can we pay for the land? | What will an income-producing property return? |
| Main drivers | Land, construction, timing, financing and exit value | Rent, operating expenses, occupancy, financing and exit cap rate |
| Cash flow | Costs typically precede revenue | Operating income over a hold period, plus exit proceeds |
| Common measures | Profit on cost, residual land value, peak debt and IRR | NOI, cash-on-cash return, DSCR and IRR |
Some rental-property spreadsheets do not model construction spending or loan draws. Check that any template covers your development period as well as operations.
Proforma vs. appraisal vs. feasibility study
Terminology varies by market. US teams commonly use development pro forma; UK teams often say development appraisal; Australian teams often say development feasibility. These can describe the same financial modeling task. A wider feasibility study also considers issues such as planning, site constraints, demand and delivery.
A simple development proforma example
This illustrative for-sale project is a simplified example, rather than a forecast for a real investment. Finance costs are assumed; they are not derived from a monthly draw schedule in this table.
| Item | Amount |
|---|---|
| Land and acquisition costs | $2,000,000 |
| Hard costs | $9,000,000 |
| Soft costs | $1,500,000 |
| Finance costs | $1,000,000 |
| Total development cost | $13,500,000 |
| Sales revenue | $16,200,000 |
| Profit before tax | $2,700,000 |
| Profit on cost | 20.0% |
| Margin on revenue | 16.7% |
Profit on cost = profit ÷ total cost. Here, $2.7 million ÷ $13.5 million = 20%. Margin on revenue uses sales revenue as the denominator: $2.7 million ÷ $16.2 million = 16.7%.
If this developer’s required profit on cost is 20%, the base case only just meets it. A 5% rise in the $9 million hard-cost budget adds $450,000. With other assumptions held constant, profit falls to $2.25 million and profit on cost to approximately 16.1%. A delay can also increase financing and holding costs; calculate that effect through the cash flow.
Use sensitivity analysis to see how changes in costs and values affect the result.
Common development proforma mistakes
- Ignoring timing. Model when costs are paid and proceeds received. An S-curve construction spending profile can help represent uneven build spending.
- Using a single sales or rental assumption. Compare a base case with downside prices, slower absorption or lease-up and higher costs.
- Omitting a cost category. Reconcile land, all construction uses, professional fees, contingency, financing, selling costs and holding costs to the source budget.
- Confusing profit with cash. A profitable project can still need more equity before sales complete. Review peak funding needs as well as the final profit.
- Treating land as a fixed input. Calculate a residual land value against your target return before setting the bid.
- Losing control of versions. Record assumptions and approvals, and identify the current model before sharing a report.
Should you use Excel or development proforma software?
Excel offers flexibility and works well when a capable modeler maintains a clearly controlled workbook. Dedicated software can help when a team needs repeatable inputs, shared projects, cash flow forecasting, sensitivity analysis and consistent reporting across multiple deals.

Frequently asked questions
What is a real estate proforma?
A real estate proforma is a forward-looking financial projection of a property or project’s income, expenses and returns. For a development, it also covers land, construction, financing and the sale or lease-up period.
What is the difference between a proforma and a feasibility study?
A feasibility study assesses whether a project can work, including financial, physical, planning and market considerations. A proforma is the financial model used to test its costs, funding and returns.
What return should a development proforma show?
There is no universal target. Required profit on cost and equity returns depend on the project’s location, asset type, delivery risk, financing and investor requirements. Agree the hurdle before bidding and test downside scenarios against it.
Can I build a development proforma in Excel?
Yes. Excel is flexible and familiar. As projects and contributors increase, a dedicated platform can help teams standardize inputs, compare scenarios and share consistent reports. Both approaches require checked assumptions and results.
Is there a free development proforma template?
Yes. Aprao’s templates directory includes nine US examples covering multifamily, build-to-rent, for-sale housing, land development, industrial, self-storage, mixed-use and condominiums. Public examples are free to view. To edit one, save a copy in an Aprao account; new users can start a seven-day free trial. These are interactive models rather than downloadable Excel templates.
