How it works
Flipping a house profitably means the resale value must exceed all your costs, and this calculator estimates the profit and return. You enter the after-repair value (ARV) — what the renovated home will sell for — the purchase price, the rehab budget, and other holding and selling costs, and it returns the estimated profit and ROI. Profit is the ARV minus the sum of everything you invest, and ROI expresses that profit as a percentage of the total invested, which lets you compare deals of different sizes. The often-overlooked category is other costs: holding costs (loan interest, property taxes, insurance, utilities while you own it) and selling costs (agent commissions, closing costs, staging) can easily run 15 to 20 percent of the ARV and turn an apparently profitable flip into a loss if ignored. Accurately estimating the ARV from comparable sales and getting realistic rehab bids are the two biggest keys to a successful flip. Many investors want a minimum profit or ROI to justify the risk and effort — the 70% rule is a common quick screen for the maximum purchase price. This calculator lets you test a deal and see how changes in purchase price, rehab, or ARV affect your bottom line. Enter the ARV, purchase price, rehab, and other costs to estimate profit and ROI.
Profit = ARV − (purchase + rehab + other costs); ROI = profit ÷ total invested × 100
The profit on a flip is the after-repair value (the resale price) minus everything you put in: the purchase price, rehab cost, and holding and selling costs. Dividing that profit by the total amount invested gives the return on investment as a percentage.

Frequently asked questions
How do you calculate house flip profit?
Subtract all your costs — purchase price, rehab, and holding and selling costs — from the after-repair value (the resale price). For a $300,000 ARV with $180,000 purchase, $40,000 rehab, and $20,000 other costs, the profit is $60,000. Dividing by the $240,000 invested gives a 25 percent ROI.
What is ARV?
ARV, or after-repair value, is the estimated market value of the property once renovations are complete — essentially the price you expect to sell it for. It is determined from comparable recent sales of similar renovated homes nearby. Accurately estimating ARV is critical, since it anchors the entire deal analysis, and overestimating it is a common cause of flips losing money.
What costs do people forget in flips?
Beyond purchase and rehab, flippers often underestimate holding costs (loan interest, property taxes, insurance, and utilities during ownership) and selling costs (agent commissions, closing costs, and staging). Together these can reach 15 to 20 percent of the ARV. Ignoring them makes a deal look far more profitable than it is, so always include them in the analysis.
What is the 70% rule?
The 70% rule is a quick screen that says a flipper should pay no more than 70 percent of the ARV minus rehab costs for a property. It builds in a margin for holding costs, selling costs, and profit. It is a starting filter, not a precise analysis, so run a full profit calculation on deals that pass it.
What ROI should I aim for on a flip?
There is no fixed target, but flippers generally want enough profit and ROI to justify the significant risk, time, and effort — many aim for a profit of at least $25,000 to $50,000 or an ROI comfortably into double digits. Because flips carry real risk of cost overruns and market shifts, a healthy margin protects against things going wrong.
