Flip profit calculator.
Find out what a flip actually makes after fees, shipping, repairs, and gas, and the most you can pay to hit your target return. Everything runs in your browser. Nothing is saved or sent.
Online preset fees are an example only. Check your platform's current fees for your category. Results are estimates, not a guarantee of what you'll sell for.
How the numbers work
- Net from the sale = sale price − (sale price × fee %) − fixed fee − shipping you pay.
- Total cost = purchase price + repairs and parts + travel and other costs.
- Profit = net − total cost. ROI = profit ÷ total cost. Margin = profit ÷ sale price.
- Most you can pay = net ÷ (1 + target ROI) − repairs − travel and other costs.
Using it before you message a seller
Set the sale price to a realistic sold price for the same model and condition, not an asking price, and pick your target ROI. The “most you can pay” figure is your ceiling for the conversation. Need an opening offer and a message too? Try the lowball offer calculator.
Doing this automatically
Pounce runs this math on every listing it finds. It prices candidates against market data, compares the asking price with your buy target, and only alerts when the numbers work. Then Insights records what you actually paid, sold for, and spent, so you see real profit per search, not estimates. See Insights.
Common questions
How do I calculate profit on a flip?
Profit = sale price − platform fees − shipping you pay − purchase price − repairs and parts − travel and other costs. ROI is profit divided by everything you spent to acquire and prepare the item.
What's the difference between ROI and margin?
ROI compares profit with what you spent: a $100 buy that makes $50 profit is 50% ROI. Margin compares profit with the sale price: $50 profit on a $180 sale is about 28% margin. Resellers usually set buy targets with ROI.
What fees should I enter?
Use your platform's current fees for your category. Local cash sales usually have none. On eBay, final value fees for most categories are commonly in the low-to-mid teens as a percentage, plus a small per-order fee, but they vary by category and change over time, so check eBay's fee page.
