Development Feasibility Calculator
Estimate profit and margin on a development project from plot size, FSI and costs.
Assumptions used in this calculation
- Simplified pro-forma: Excludes land acquisition cost, financing interest and taxes, it estimates construction-to-sale margin only.
About this calculator
Before committing to a development deal, a developer needs a fast answer to whether the numbers even work, without building a full financial model, and that means chaining together several calculations: buildable area from zoning limits, total project cost, expected revenue, and the profit that falls out of the difference. This calculator multiplies plot area by permissible FSI to find buildable area, multiplies that by a construction cost per square foot and inflates it by an approvals/marketing/other cost percentage to find total project cost, multiplies buildable area by an expected selling price per square foot to find revenue, and subtracts cost from revenue to show estimated profit and margin. Enter plot area, FSI, construction cost, selling price and other costs, and get a complete quick pro-forma in one pass instead of building a spreadsheet from scratch for an initial go/no-go read. It's a simplified model that excludes land acquisition cost, financing interest and taxes, treat it as a fast feasibility screen, not a bankable financial projection.
Worked example
5,000 sqft plot, FSI 2, ₹2,200/sqft cost, ₹8,500/sqft sale price
Result: Estimated profit ≈ ₹2.9 crore at ~34% margin
