eBay Profit Calculator.
eBay tells you what you sold. It never tells you what you kept. Enter one sale below and see the real number after the final value fee, the per-order fee, your label, your packaging, and what the item cost you, plus the price you would need to charge to hit the profit you actually want.

These presets are common eBay US rates on the portion of a sale up to $7,500, with 2.35% above that and a per-order fee of $0.30 on orders of $10 or less, $0.40 above, all applied automatically. eBay's rates vary by category and change over time, and a few categories use different tier breaks, so treat the preset as a starting point: check eBay's current fee schedule or your seller invoice and set your exact rate.
Price it at $0.00 to net that after every cost above.

The gap
Why your sales number lies to you.
Every cost in this calculator comes out of your pocket at a different moment. The fees leave before the payout lands, the label gets bought the next morning, the packaging was a bulk order months ago, and the item cost left your account before you ever listed. Nothing ever presents the total.
That is why sellers can quote their sales number instantly and go quiet when asked what they earned. The sales number arrives assembled. The profit number has to be built, sale by sale.
The pattern the calculator makes obvious: percentages scale with price, but the per-order fee, the label, and the packaging do not care what you sold. On a $100 sale they are noise. On a $12 sale they are the margin.
Use the target-profit box before you list, not after you sell. Deciding the profit first and letting the price follow is the single habit that separates sellers who make money from sellers who make sales.

That was one sale
Your store made thousands of them.
This page does one sale at a time, typed by hand. WaxEngine connects to your eBay account and rebuilds this exact math across every order from your last two years, fees, labels, refunds, and item costs included, then keeps it live. One honest profit number for the whole store, updated as you sell.
The listings themselves come from the same engine: eBay listing software for one card at a time, the eBay bulk listing tool when the pile is four hundred deep.
