Why price minus cost overstates a flip's profit
'Bought for $10, sold for $45' looks like $35 profit. It isn't. Platform fees, the shipping label, packaging, sales tax or a buyer's premium paid when sourcing, and the driving to source and ship all come out of that first. This calculator adds them up for one flip at a time.
Example (the calculator's starting numbers, eBay, no Store)
- Sale price
- $45.00
- eBay fees (13.6% + 40¢)
- $6.52
- Item cost + shipping label + supplies
- $10.00 + $8.00 + $1.00
- Driving (12 miles × $0.76)
- $9.12
Price minus cost looks like $35.00 profit. The true profit is $10.36, a 104% return on the $10 buy-in and $13.81 an hour for 45 minutes of work.

Don't skip mileage and hours
- Mileage covers your share of a sourcing trip plus any post office run. Use the current IRS standard business mileage rate as a starting point, or your own tracked cost per mile.
- Hours turns profit into a rate you can compare to other work. Under $15 an hour on a flip is a signal to batch your listing and shipping, or focus on higher-priced items.
- Track receipts. Mileage and item cost with tax are usually deductible business expenses at tax time; keep a simple log as you go.

Questions people ask
How do I calculate true profit on a resale flip?
Start from the sale price plus any shipping charged, then subtract platform fees, what you paid for the item (plus any sourcing tax or buyer's premium), your shipping label, packaging, and the cost of the miles you drove to source and ship it.
Why does my profit look smaller here than 'price minus cost'?
Because platform fees, shipping supplies and driving all come out of the sale too. This calculator counts every one of them, not just what you paid for the item.
What counts as a good profit per hour when reselling?
There's no fixed benchmark, but many resellers treat under $15 an hour as a sign to batch tasks (photographing and listing several items at once) or focus on higher-priced categories.
Should I track mileage for reselling?
Yes. It's often a deductible business expense, and it's also a real cost that a simple 'price minus item cost' profit calculation misses entirely.
Can I use this for a platform that's not in the list?
Yes. Choose Other: enter the fee, then enter that platform's percentage and any fixed fee per sale from its own fee page.
