What this calculator does

A flip's return depends on how much you pay, how much you spend fixing it up, what it costs to sell, and what it's actually worth once finished. This calculator combines all four into a net profit and a return on the total cash you put into the deal.

The formula

Net Profit = ARV − Purchase Price − Rehab Cost − Selling Costs
ROI = Net Profit ÷ (Purchase Price + Rehab Cost)

ARV (after-repair value) is your best estimate of what the property will sell for once the rehab is complete, usually based on comparable sales nearby.

Worked example

$150,000 purchase, $30,000 rehab, $230,000 ARV, 6% selling costs

Purchase price$150,000
Rehab cost$30,000
Total project cost$180,000
After-repair value (ARV)$230,000
Selling costs (6% of ARV)$13,800
Net profit$36,200
Return on investment20.11%

What is a good ROI on a house flip?

Flip ROI measures profit against your total cost to buy, renovate, and sell. Many flippers aim for a return that meaningfully beats a buy-and-hold rental to compensate for the higher risk and active effort, but the right target depends on how long capital is tied up and how much can go wrong.

Because a flip's profit is squeezed between purchase price, rehab cost, and after-repair value, small misses on any of the three can wipe out the margin. Build in conservative estimates and a contingency, and confirm the deal still works if the budget runs over.

Frequently asked questions

Subtract your total costs (purchase price, rehab, holding, and selling costs) from the sale price to get net profit, then divide profit by your total invested cost. This calculator estimates net profit and ROI from your purchase price, rehab budget, after-repair value, and selling costs.
Total cost includes the purchase price, the full rehab budget, holding costs such as taxes, insurance, and loan interest during the project, and selling costs like agent commissions and closing fees. Leaving any of these out overstates your true return.
Renovations routinely uncover surprises, and timelines slip, which raises holding costs. A contingency, often 10% to 20% of the rehab budget, absorbs overruns so a single problem does not erase your profit. Always test whether the flip still works with the contingency spent.
Flip ROI is a one-time return realized at sale, driven by forced appreciation from renovation. Rental ROI accrues over years from cash flow, loan paydown, and appreciation. Flips return capital faster but carry more execution risk and effort per dollar earned.
