Fix & FlipDirect answer
What this calculator does
A fix-and-flip calculator estimates profit after purchase, financing, rehab, contingency, holding, and selling costs, then solves for the offer price that can support a target profit or ROI.

Follow the assumptions into the result.
Illustrative inputs only—not a property recommendation. Replace every assumption with verified numbers before making a decision.

When the deal misses
Don’t stop at “no.”
Test the supported levers.
DealCooker can test a lower purchase price and, when applicable, a larger down payment against the active strategy’s workout logic. It does not optimize interest rates, points, loan products, or every financing term.
Calculation methodology
How DealCooker models this strategy
DealCooker builds an acquisition and rehab budget, applies hard-money leverage, interest, points, holding costs, contingency, sale price, and selling costs, then calculates net sale cash, total ROI, annualized IRR, and a maximum allowable offer from the selected targets.

What investors ask about Fix & Flip
What costs belong in a flip analysis?
Purchase and closing costs, rehab, contingency, permits, utilities, taxes, insurance, financing interest and points, holding costs, commissions, and other selling costs should be included.
What is maximum allowable offer?
It is a modeled purchase-price ceiling that works backward from sale value, project costs, and the selected profit or ROI target. It is not an appraisal or market-value opinion.
Why model both ROI and annualized IRR?
ROI summarizes total project gain relative to cash invested. Annualized IRR also reflects when cash enters and leaves the project, so timing affects the result.
Does DealCooker estimate flip taxes?
No. Tax treatment depends on facts and taxpayer circumstances. DealCooker models project economics before tax; consult a qualified tax professional.
