Project your flip's net profit and ROI — purchase, rehab, holding, selling costs vs. sale price.
Enter your email to unlock this calculator and the full rental + ROI toolkit — Cap Rate, Cash-on-Cash, DSCR, Fix & Flip, BRRRR. Free.
Flip profit is the sale price minus everything it took to get there: purchase, rehab, holding costs (loan interest, taxes, insurance, utilities while you own it), buying and closing costs, and selling costs (agent commission, transfer taxes). ROI is that profit divided by the total cash and costs you put in. The number that kills flips isn't the purchase price — it's the costs investors forget: a longer hold, a rehab overrun, or selling costs they didn't budget. Price every line conservatively.
DLS InvestTrack puts these calculators, kill flags, and a stress test in one place.
