House Flip Profit, ROI, and Margin Calculator
Sums purchase, renovation, and holding costs as cash in, subtracts selling costs from sale price for profit, then reports ROI and profit margin.
Limitation: Educational estimate only—not investment advice.
How to Estimate Flip Profit
Enter purchase, rehab, hold, sell, and exit amounts in one currency.
Choose a display currency; the calculator does not convert currencies.
Put interest in holding costs
Financing interest is not calculated automatically. Add estimated interest and carrying costs to the holding field.
What Flip Profit Means
Cash in aggregates purchase, renovation, and holding costs. Profit subtracts that total and selling costs from sale price. ROI uses cash in as the denominator; margin uses sale price. Zero cash in or zero sale price makes the matching ratio undefined.
House Flip Examples
Standard flip scenario
Entered project costs
Profit and ROI
Cash in = 200,000 + 40,000 + 10,000; profit = 300,000 − 250,000 − 15,000.
Smaller project
Entered project costs
Profit and ROI
Cash in = 125,000; profit = 150,000 − 125,000 − 8,000 = 17,000.
Stress-test sale price
Lower the sale price until profit approaches zero to understand your margin of safety before committing capital.
