eBay Profit Margin Calculator
Your eBay 'profit' isn't sale price minus item cost. Final value fees, payment processing, and shipping all eat the margin. This shows your real net per unit under buyer-paid vs free shipping, so you know what listing price actually clears.

How the estimate works
Net profit = sale price − item cost − final value fee (eBay ~13.25% on the item price, or $0.30 floor in simple categories) − payment processing (~3% + $0.30) − shipping cost (yours if free shipping, buyer's if buyer-paid). eBay adds a final value fee on the portion of shipping collected too — modeled here.

Formula and assumptions
Net profit = sale price − item cost − final value fee − payment processing − shipping (yours) − other fees. eBay's ~13.25% final value fee applies to the item price plus any shipping you collect; most simple-category listings carry a $0.30 minimum. Payment processing runs roughly 3% + $0.30 on the total collected. Under free shipping you eat the postage but pay final value fee on the item price only; under buyer-paid you collect shipping but pay the final value fee on it too — the net difference is what this tool makes explicit.
eBay Profit Margin Calculator questions
How much does eBay take per sale?
Roughly 13.25% final value fee on the item price (more for some categories, $0.30 minimum on simple listings) plus ~3% + $0.30 payment processing. Promoted listings and upgrades add more.
Is free shipping worth it?
It can lift conversion, but you absorb the postage. This calculator shows the exact margin cost so you can decide: to net the same under free shipping you must raise the item price or cut cost.
Does eBay charge final value fee on shipping?
Yes — the final value fee applies to the item price plus shipping you collect. That's why 'free shipping' with a higher item price can actually cut the fee base slightly.
