Fix & Flip Calculator

How to use this calculator

Enter the purchase price and buying costs, your rehab budget and expected hold period, your loan terms, and the after-repair value you expect at sale. The calculator carries the loan interest and points over your hold, subtracts selling costs, and shows your net profit and ROI live as you adjust the numbers.

What the metrics mean

• Net profit — after-repair value minus every cost to buy, fix, hold, finance, and sell.
• ROI (cash) — net profit ÷ the actual cash you invested (total cost minus the loan).
• Annualized ROI — cash ROI scaled to a full year — rewards shorter hold times.
• Profit margin — net profit as a percent of the sale price; a cushion against surprises.

Frequently asked questions

How do you calculate fix and flip profit?

Net profit = after-repair value − total project cost − selling costs. Total project cost includes the purchase price, buying closing costs, rehab budget, holding costs, and financing (loan interest and points).

What is a good ROI on a house flip?

Many flippers target at least a 10–15% return on the after-repair value, or a cash-on-cash ROI of 20%+ on the actual capital invested. Shorter hold times raise your annualized return.

What are typical selling costs on a flip?

Plan on roughly 7–9% of the sale price for agent commissions, closing costs, and concessions. This calculator defaults to 8%.
