How Calculations Work

Net Profit

Net Profit = ARV - Purchase - Closing (Buy) - Rehab - Holding - Selling Costs

ROI

ROI = Net Profit / Total Cash Invested x 100%

70% Rule

Max Purchase = (70% x ARV) - Estimated Rehab Costs

A common rule of thumb used by house flippers to ensure a profitable margin after all costs.

Annualized ROI

Annualized = ((1 + ROI) ^ (12 / months)) - 1

Extrapolates your flip ROI to an annual rate for comparing against other investments.

Frequently Asked Questions

How do you calculate profit on a house flip?▾

Profit = Selling Price - (Purchase Price + Closing Costs + Renovation Costs + Holding Costs + Selling Costs). ROI is the profit divided by total investment, expressed as a percentage.

What is the 70% rule in house flipping?▾

The 70% rule says you should pay no more than 70% of the After Repair Value (ARV) minus renovation costs. For example, if ARV is $300,000 and repairs cost $50,000, max offer is $300,000 × 0.70 - $50,000 = $160,000.

What holding costs should I budget for?▾

Holding costs include monthly mortgage payment, property taxes, insurance, utilities, HOA fees, and loan interest. Typical flips take 3-6 months, so these costs add up quickly.
