Calculation notes
Understand the House flipping profit calculator
Net profit = sale price − purchase, buying costs, rehab plus contingency, holding costs, agent commission, and sale closing costs. Break-even sale price solves those costs including the commission percentage. The calculation runs locally and keeps cash-flow timing consistent with the stated assumptions.
Formula and logic
How do I calculate net profit on a house flip after all costs?
Net profit = sale price − purchase, buying costs, rehab plus contingency, holding costs, agent commission, and sale closing costs. Break-even sale price solves those costs including the commission percentage.
Worked example
What rehab budget results from $45,000 plus 10% contingency?
$45,000 rehab with a 10% contingency budgets $49,500. Holding six months at $1,600 adds another $9,600 before selling costs.
How to read the result
How is a flip break-even sale price calculated with commission?
ROI divides modeled profit by cash committed before sale.
The 70% rule is only a screening benchmark: 70% of ARV minus rehab, not a valuation or offer recommendation.
Limits and assumptions
What does the house-flipping 70% rule include and exclude?
Excludes financing interest unless entered in monthly holding cost, acquisition taxes not entered as closing costs, permit surprises, schedule delays, income/capital-gains tax, price changes, and contractor risk.
