What the Property Development Profit Calculator is for
Estimate development profit, revenue margin, and profit on cost.
It keeps income, operating costs, financing, invested cash, value, timing, and exit assumptions explicit so you can reproduce the result and compare genuinely consistent scenarios.
Calculation structure
Keep income, costs, and value in the right period
Profit = gross development value − land, construction, professional, finance, and selling costs.
Visual explanation

Acquire→Improve→Sell or refinanceTrack every entered cost before measuring profitProfit = gross development value − land, construction, professional, finance, and selling costs.
Read the result correctly
Use the result with its boundaries
2,000,000 revenue and 1,600,000 total costs produce 400,000 profit, 20% margin, and 25% profit on cost.
This is a simple undiscounted appraisal; use IRR for time-sensitive cash flows.
Quick guide
How to use this calculator
Enter a single internally consistent property scenario.
Use the field labels to preserve each page's specific investment, transaction, lease, development, or lodging convention.
Review the calculator-specific boundary before interpreting the result.
