Fix and Flip Calculator — Estimate Your Flip Profit
A fix and flip is a real estate investment strategy where you buy a distressed property, renovate it, and sell it for a profit — typically within 6-12 months. Profit is calculated as: ARV (after repair value) minus purchase price, minus rehab costs, minus holding costs (taxes, insurance, utilities during the project), minus selling costs (agent commissions and closing fees), and minus financing costs (hard money interest and points). The key is buying low enough so that even after all these costs, you have a healthy profit margin.
The 70% rule is a quick screening tool used by experienced flippers: never pay more than 70% of the ARV minus repair costs. For example, if a house will be worth $300,000 after repairs and needs $50,000 in rehab, your maximum purchase price should be (0.70 x $300,000) - $50,000 = $160,000. This built-in margin protects you from cost overruns, market shifts, and unexpected holding costs. While it's a guideline rather than a hard rule, it's an excellent starting point for evaluating any flip.
Frequently Asked Questions
What is the 70% rule?
The 70% rule states you should never pay more than 70% of a property's after-repair value (ARV) minus repair costs. For example, if ARV is $300,000 and repairs cost $50,000: max offer = (0.70 x $300,000) - $50,000 = $160,000. This gives you a 30% margin to cover holding costs, selling costs, financing, and your profit. While it's a guideline rather than a strict rule, it's an excellent starting point for evaluating any flip.
What are holding costs?
Holding costs are the expenses you pay while you own the property during renovation and until it sells. This typically includes property taxes, insurance, utilities (water, electricity, gas), HOA fees, and loan interest. The longer your flip takes, the more holding costs eat into your profit. Most flippers budget 6-12 months of holding costs and add a contingency for delays.
How much profit should a flip make?
Most experienced flippers target a 10-15% return on cost (ROI) minimum, though in competitive markets this varies. For a $200,000 total project, that means $20,000-$30,000 in profit. Factors that affect your profit target: market risk, project complexity, holding period, and your cost of capital. Always model your deal with pessimistic assumptions (10% lower ARV, 20% higher repairs) to make sure you have enough margin for things to go wrong.
