Calculate Your Expected Profit on a Spec Home Build
Enter the lot purchase price you've agreed to (or are considering), your estimated construction costs, and the target sale price. The calculator shows your expected gross profit and margin.
This is the complement to the Lot Value Calculator — instead of solving for what to pay for a lot, it solves for how much you'll make on the deal.
Adjust any input value and the calculator will recalculate instantly. Editable fields are shown in accent color.
