House Flipping Profit Calculator
Check a flip before you make an offer. Enter the purchase price, rehab budget and after-repair value (ARV) to see total cost, net profit, return on cash and the maximum offer under the 70% rule.
How the house flipping profit calculator works
A house flipping calculator should do more than subtract the rehab from the ARV. Holding costs, loan interest, points and selling costs are where thin flips go wrong, so they are all built in here.
The 70% rule is a quick screen, not a promise: investors often limit their offer to 70% of the ARV minus repairs. The calculator shows that number next to your actual offer so you can see the gap at a glance.
Enter your own numbers. Rehab budgets and ARVs are estimates, so run the deal again with a higher rehab cost and a lower ARV to see if it still works.

Frequently asked questions
What is the 70% rule in house flipping?
It is a rule of thumb that caps your purchase price at 70% of the ARV minus the repair cost, leaving room for costs and profit.
How do I calculate flip profit?
Subtract all costs from the ARV: purchase, rehab, buying and holding costs, interest, points and selling costs. This calculator does that for you.
Does this include taxes on the profit?
No. The result is before income tax. Ask a tax professional how a flip is taxed in your situation.
What if I pay all cash?
Set the loan amount to 0. Interest and points drop to zero and cash invested rises.
