70% Rule Real Estate Calculator
The 70% rule is a quick screening method many fix-and-flip investors use to estimate a potential maximum purchase price. It generally starts with the property’s after-repair value (ARV), multiplies that value by 70%, and subtracts the estimated renovation budget.
Use this calculator to estimate a rule-based offer price, compare it with your proposed purchase price, and evaluate potential profit after additional project expenses. The 70% rule is only a starting point. Local market conditions, financing, closing costs, holding time, resale expenses, and unexpected repairs can all change the outcome.

The 70% rule is a rough investor screening guideline, not a guarantee of profitability or a substitute for a detailed analysis. In its traditional form, the maximum offer is calculated as ARV multiplied by the rule percentage, minus estimated repairs. The additional project costs entered here are used for the separate profit estimate and target-profit purchase calculation. Make sure those costs include all applicable acquisition, financing, holding, and resale expenses, and avoid double-counting costs already included in the renovation budget. Actual results depend on market value, scope of work, financing, timeline, and unforeseen expenses.
