What is Fix and Flip Profit Calculator?

The Fix and Flip Profit Calculator helps investors analyze the profitability of house flipping projects.

Formula

Total Investment = Purchase Price + Rehab Costs + Closing & Holding Costs

Profit = ARV − Total Investment

ROI = (Profit / Total Investment) × 100

Profit Margin = (Profit / ARV) × 100

70% Rule: Purchase Price + Rehab ≤ ARV × 0.70

Where: ARV = After Repair Value

Example: $280K ARV − ($150K Purchase + $40K Rehab + $15K Costs) = $75K Profit

How to Calculate

Enter purchase price and rehab costs.
Input ARV and additional costs.
View profit and ROI.

Example

A $150K purchase with $40K rehab, $280K ARV, and $15K costs yields significant profit.
