Fix-and-Flip Profit Calculator

A free fix-and-flip calculator that estimates net profit, return on investment and the 70% rule before an offer goes in. It accounts for purchase price, rehab budget, financing cost, holding and carry, and selling costs, so the margin shown is the margin that survives closing rather than an optimistic spread. Built for investors sizing a deal quickly against ARV and a realistic timeline. Free to use, no signup required.
