Calculator
Fix & Flip
Enter after-repair value, purchase price, one rehab budget, hold costs, and up to three liens. The loan basis can be ARV, purchase plus rehab, or purchase price. Net profit, total-cost ROI, cash to close, and committed capital update from those inputs.
Rehab is a lump sum on purpose. This calculator does not price line-item repairs or pull comps. The working calculator, saved deals, and PDF export are available after you start a trial.
