Flip profit calculator
Work out what a flip actually pays before you drive out to it. Fees come off the sale price, gas comes off your profit, and your time is worth something — this does all three and gives you the break-even price to hold in your head while you negotiate. No account, nothing saved, nothing sent anywhere.

How to read the numbers
ROI is the one to optimise. Margin tells you how much of the sale price you keep; ROI tells you how hard your cash is working. If you have $500 of buying money, five $100 flips at 80% ROI beat one $500 flip at 40% — and they turn over faster.
Break-even is your negotiating floor. Know it before you message the seller. It is also the number that tells you when to cut a stale listing loose instead of letting it eat storage space for another month.
Effective hourly is the reality check. A lot of flips that look fine on profit fall apart once you count the 40-minute drive each way. If the hourly is bad, the fix is usually sourcing closer to home or buying in bigger lots — not squeezing another $10 out of the seller.
One number this cannot give you is what the item actually sells for in your area. Check real sold prices, not asking prices, before you trust the sale price you typed in.
Questions people ask
How do you calculate profit on a flip?
Profit = sale price − (purchase price + platform fees + shipping + supplies + travel). Platform fees are charged on the sale price, not on your profit, which is the step most people skip. This calculator applies the fee to the sale price and subtracts every other cost before showing the number.
What is a good ROI for flipping?
Most resellers target at least 100% return on cash — buy at $50, sell at $140, keep about $50 after fees. Under roughly 30% ROI a flip usually is not worth the drive, the listing time, and the risk of the item sitting. Speed matters too: 40% ROI on something that sells in two days beats 120% on something that sits for six months.
Do I need to include my time?
Yes, if you want a decision you can trust. A $40 profit on a flip that takes four hours of driving, cleaning, photographing, and shipping is a $10/hour job. The effective hourly figure exists to make that visible before you commit a Saturday.
What is the break-even sale price?
It is the lowest price you can accept and still not lose money, after fees and costs. Work it out before you list, because it is the number you need when a buyer opens with a lowball offer and you have thirty seconds to decide.
Are the platform fee rates exact?
They are typical published rates for common consumer categories and are editable. Actual rates vary by category, store subscription, promotions, and payment processing, so check a recent payout statement and enter your real rate for an exact answer.
