About this tool
What the Fix and Flip Profit Calculator does
A flip earns the sale price minus purchase, renovation, holding, financing and selling costs. Because flips tie up cash for months, this calculator also annualises the return. The 70% rule offers a quick ceiling: pay no more than 70% of the after-repair value minus repair costs.
Formula
- Total costs = purchase × (1 + buying costs) + renovation + holding + financing + sale × selling costs
- Profit = sale price − total costs
- 70% rule: maximum offer = ARV × 70% − renovation
Worked example
Using the starting values in the calculator above:
| Input | Value |
|---|---|
| Purchase price | $220,000 |
| Buying costs | 2% |
| Renovation budget | $60,000 |
| Months held | 6 |
| Holding costs per month | $2,500 |
| Loan points and fees | $6,000 |
| Sale price (ARV) | $360,000 |
| Selling costs | 8% |
| Your cash invested | $90,000 |
| Result | Value |
|---|---|
| Net profit | $25,800 |
| Return on cash | 28.7% |
| Annualised return | 65.6% |
| Profit as share of sale price | 7.2% |
| Maximum offer (70% rule) | $192,000 |
| Total costs | $334,200 |
How to read the result
Renovations and timelines overrun more often than not. Run the numbers with 10% to 20% more renovation cost and two extra months.
Short holding periods can make modest profits look like huge annualised returns; judge flips on absolute profit and risk too.
