Totals include only the costs you entered. Results are before income or capital gains tax and are not a promise of profit; a loss is as possible as a gain.

How do I calculate profit from building and selling a house?
Subtract the total project costs from the estimated sale proceeds. Include construction, land and the other costs relevant to your project, rather than comparing the sale price with the build contract alone. The calculator uses your entered assumptions; a positive result is not a valuation, a completed-sale comparison or a promise of profit.
Which costs should I include in construction return on investment?
Consider acquisition costs, legal and design fees, permits, site works, connections, finance, contingency and selling expenses where applicable. Keep all inputs in the same currency and check whether taxes are included. This calculator’s displayed return is before income or capital gains tax; unentered costs are not automatically added.
How can I test whether a property development still makes a profit if costs rise?
Use the downside sensitivity results to compare the baseline with lower sale proceeds or higher building costs. Recheck the underlying local resale evidence, the build specification and the time needed to sell. A contingency helps budget for uncertainty, but it does not remove market risk or guarantee that a project remains profitable.
