The whole fix-and-flip business fits in one formula: ARV minus purchase price minus repairs. This calculator runs that math and stress-tests the deal against the classic 70% rule.
Holding costs turn a pretty gross profit into the real number over your months of carry.
Offer at or below ARV × 0.7 minus repairs and you keep a cushion for surprises.
Most flippers target 10–15% of ARV in profit before they get excited.
