Construction Feasibility. A clearer first-pass view.
Test an indicative development cost stack, gross realisation value, contingency, sales costs, finance assumptions, profit, return on cost, peak debt, and equity requirement.
Give project stakeholders a common early-stage feasibility language before a detailed quantity-surveyor review, lender submission, or capital-structure decision.
Keep the source figures visible
Gross realisation value
Expected project revenue across residential, commercial, and other components.
Acquisition and build costs
Site, duty, hard costs, professional fees, authorities, marketing, and other project costs.
Timing and contingency
Build and sales terms, cost contingency, and the timing assumptions behind the project.
Funding assumptions
Interest, fees, senior debt constraints, presales, equity, and any mezzanine layer.
Turn inputs into a reviewable signal
Profit and margin
Indicative project profit, margin on revenue, and return on project cost.
Peak debt
The highest modelled debt requirement across the entered project timing.
Equity requirement
The modelled gap between project funding needs and entered debt assumptions.
Leverage signals
Indicative cost and value constraints for an early lender-fit discussion.
Small residential development
A project has an indicative gross realisation value of $9.60 million and a $7.14 million cost stack before finance and tax.
Profit before finance and tax = $9,600,000 − $7,140,000 = $2,460,000. Return on cost = $2,460,000 ÷ $7,140,000 = 34.5%.
Before the model applies interest, line fees, establishment fees, GST, and tax assumptions.
Profit before finance and tax divided by gross realisation value.
Profit before finance and tax divided by the entered pre-finance cost stack.
Move from raw figures to a better review conversation
The tool organises an early scenario. Keep the evidence, assumptions, and professional review attached to the result.
Build the revenue and cost stack
Enter the expected realisation and each material acquisition, build, and selling cost.
Set timing and funding
Add project duration, contingency, interest, fees, presales, debt limits, and equity.
Stress the feasibility
Change revenue, cost, timing, rate, and leverage assumptions before progressing the project.
Keep the result in context
Feasibility is only as reliable as the revenue, cost, timing, GST, presale, and funding assumptions entered.
The calculator is an early scenario model and does not replace a valuer, quantity surveyor, tax adviser, planner, lawyer, or lender assessment.
Cost overruns, sales delays, interest-rate changes, approval conditions, and market movements should be stress-tested separately.
Displayed leverage signals are not an offer, approval, or statement of current lender appetite.
Useful for developers & development advisers
Give project stakeholders a common early-stage feasibility language before a detailed quantity-surveyor review, lender submission, or capital-structure decision.
About the Construction Feasibility
Use these answers to understand the tool's purpose before relying on its indicative output.
What is gross realisation value?
Gross realisation value is the total estimated revenue from selling or realising the completed project, before project costs, finance, tax, and other deductions.
What is return on cost?
Return on cost compares the modelled project profit with the cost base used in the calculation. The exact definition should be checked because models can include or exclude finance, tax, land, and other items differently.
Does the calculator provide a construction-finance approval?
No. It organises an indicative scenario. A lender will complete its own feasibility, valuation, quantity-surveyor, presales, borrower, experience, credit, security, and exit review.
Use the calculator, then keep the assumptions attached to the result.
The result is an indicative workflow signal. Broker, adviser, valuer, accountant, and lender review still applies to the full scenario.
