Flip Spread Calculator

Run the numbers on a fix-and-flip — after-repair value minus purchase, rehab, holding, financing, and selling costs — and check the deal against the 70% rule.

Spread = ARV − (Purchase + Rehab + Holding Costs + Financing Costs + Selling Costs)

FAQ

What's the 70% rule?

A quick screening rule: Maximum Purchase Price ≈ (ARV × 70%) − Rehab Cost. Treat it as a fast filter, not a final underwrite.

What counts as a selling cost?

Agent commissions (typically 5–6% combined), closing costs, and any staging or concessions — most flippers budget 8–10% of the sale price combined.

What are holding costs?

Financing interest, property taxes, insurance, and utilities for every month the property is owned but not yet sold.
