Know your real return before you buy. Freddie calculates ROI, annualized return, and profit margin on every flip deal in seconds.
Dan White, 20-year fix-and-flip veteran in Northern Virginia, used FreeDealCalc to analyze a $130,000 wholetail opportunity in under 5 minutes. No spreadsheet. No paid software. Just Freddie.


"I've been flipping houses for 20 years and I built this tool because nothing free was actually good enough. Freddie does what I used to do with spreadsheets — but in seconds, for free, for every investor who needs it."
A buyer who purchases this property as a wholetail deal undertakes all renovation work at their own direction, cost, and risk. The seller makes no representations regarding property condition and all sales are as-is. Buyer is responsible for all due diligence, inspections, and compliance with local codes and regulations.
Fix and flip ROI equals net profit divided by total cash invested, multiplied by 100. Net profit is your sale price minus purchase price, rehab costs, holding costs, financing costs, and selling costs. Our calculator handles all of this automatically.
Most experienced flippers target 15-20% ROI minimum per deal. On a 6-month flip that translates to 30-40% annualized return. Deals below 10% ROI are generally not worth the risk and capital unless you have very low holding costs.
Purchase price, closing costs on acquisition, all rehab costs, holding costs (taxes, insurance, utilities, HOA), financing costs (points, interest), agent commissions on sale, closing costs on sale, and any capital gains tax impact.
The longer you hold, the more your holding and financing costs eat into profit. A $50K profit on a 3-month flip is far better than the same $50K on a 12-month flip. Annualized ROI accounts for this — always compare deals on annualized basis.
Target at least 20% profit margin (net profit divided by ARV) as a general rule. On a $300K ARV property that means $60K minimum net. Markets with higher price points can work at tighter margins if absolute dollar profit is sufficient.
Accuracy depends on your inputs. The calculator is only as good as your ARV estimate and rehab budget. Freddie will flag deals where your inputs seem aggressive and suggest more conservative scenarios so you can stress-test your numbers.
