eBay Fee Calculator – What a Sale Really Leaves You

Five sales, five keeps — and the rate you must check yourself

Every figure below was run through the calculator above, starting from its default sale — $100 at the page’s example rate of 13.25%, plus a $0.30 per-order fee, with no payment processing, listing or shipping lines — and changing one thing at a time. Read the scope first, because it governs the whole table: the 13.25% is an example starting value only, not a statement of any current category fee schedule. Marketplace fee schedules vary by category, by seller terms and over time, and this page deliberately does not reproduce eBay’s current schedule — it treats the percentage as an input for you to replace with the rate that applies to your own listing, checked against your own listing terms. The maths below is exact; the rate is your responsibility, and any figure here that uses 13.25% is an example worked at the page’s starting value, not a claim about what eBay currently charges.

The default row is the page’s anchor case, and it shows the whole formula: total fees equal sale price times fee percentage divided by 100, plus the per-order fee, plus extra fees — 100 × 0.1325 = $13.25, plus $0.30, equals $13.55, so you keep 100 − 13.55 = $86.45, and the effective fee rate is 13.55 ÷ 100 = 13.55%. Note that the effective rate (13.55%) is higher than the headline percentage (13.25%) by exactly the per-order fee’s share — $0.30 on a $100 sale is 0.30 percentage points. That gap is the first thing the breakdown teaches: the rate you enter is never the whole cost, because the per-order fee and every extra line sit on top of it, and the effective rate is the only rate that describes what you actually paid.

The $1,000 row shows the per-order fee diluting as the sale grows. At $1,000 the final-value fee is $132.50 and the per-order fee is still $0.30, for total fees of $132.80 and $867.20 kept — an effective rate of 13.28%, lower than the default’s 13.55% even though the percentage never changed. The $0.30 that cost 0.30 points on a $100 sale costs only 0.03 points on a $1,000 sale. Small sales therefore bear proportionally heavier fees than large ones at the same percentage, which is why a fee structure that looks acceptable on a $1,000 item can be punishing on a $10 item — and why the effective rate, not the headline percentage, is the number to compare across sale sizes. The same dilution runs in reverse for the extra lines: $5 of shipping shortfall is 5 points on a $100 sale but 0.5 points on a $1,000 one.

The last two rows carry the same total by different routes, and the coincidence is instructive. Adding $3 of payment processing and $2 of listing fees to the default sale gives total fees of $18.55 and $81.45 kept; adding a $5 shipping shortfall instead gives exactly the same $18.55 and $81.45. The breakdown is what distinguishes them: in the first case the extra $5 is two lines with their own causes, in the second it is one line — the gap between what postage cost you and what the buyer paid for it. A lump-sum fee figure would hide that distinction; the line-by-line breakdown shows exactly which line did it, which is the page’s whole design philosophy. If the amount you keep is smaller than you expected, do not argue with the total — read the lines, find the one that grew, and fix that line’s cause, whether it is a processing charge you forgot, a listing fee you did not expect, or postage you undercharged.

One more boundary, stated plainly because it is the most expensive misunderstanding after the rate itself: what you keep is not profit. The $86.45 on the default sale is what remains after the fees counted above. It still has to cover what the item cost you, what you paid to acquire or make it, the postage you actually paid beyond any shortfall line, packaging, your time, and any tax you owe on the sale — none of which this calculator counts, because they belong to your own books. Pretending the keep figure is profit overstates every sale by exactly the cost of the item, and a seller who prices from the keep figure without subtracting costs will discover the error only when the accounts are done. The calculator tells you what the marketplace takes; your books tell you what you made.

Pricing with the effective rate, not the headline rate

The single most useful habit this page teaches is to price from the effective rate — total fees divided by sale price — rather than from the percentage you typed in. On the default sale the headline is 13.25% and the effective rate is 13.55%; on the $1,000 sale the headline is still 13.25% and the effective rate is 13.28%; with processing and listing lines added, the headline is still 13.25% and the effective rate is 18.55%. Three sales, one headline, three different true costs. Any pricing rule built on the headline — “I need to clear 13.25% for fees” — understates the cost on every sale that carries any extra line, and the understatement grows with the lines, not with the price. Build the price from the effective rate of a sale like the one you are actually making, with its actual extra lines, and the margin you think you have will survive contact with the breakdown.

The second habit is to check the rate before every pricing decision, not once when you first open the page. Fee schedules vary by category, by seller terms and over time, and a percentage that was right for your last category, your last store tier, or last year may not be right for this listing. This page does not reproduce the current schedule and does not update it for you — that omission is deliberate, because a hard-coded schedule would go stale and mislead, but it means the responsibility sits entirely with you. Before you rely on any keep figure here, confirm the percentage and the per-order fee against your own listing terms for that category, and confirm whether postage counts toward the fee base on your terms: the page’s guidance is to keep postage out of the sale-price box unless your fee terms say it counts, because the fee percentage applies to the price you enter, and entering a price that includes postage when your terms exclude it (or excluding it when they include it) misstates the fee by the postage’s share.

The third habit is to treat small sales with extra suspicion. The per-order fee, any fixed processing charge, and any listing fee are fixed amounts, so they weigh heaviest exactly where the sale is smallest — and small sales are also where a shipping shortfall of a few dollars is proportionally largest. A $100 sale at the example terms keeps $86.45 before costs; a $10 sale at the same terms would keep far less in proportion, because the $0.30 per-order fee alone is 3% of it before the percentage fee is even counted. That arithmetic is why experienced sellers set minimum prices, build postage into the item price where terms allow, or decline sales whose fee structure leaves nothing after costs — decisions the calculator informs but cannot make, because it does not know your costs. Use the keep figure as the starting point for your own margin calculation, never as the margin itself.

A seller’s checklist for the keep figure

Before you trust any keep figure from this page, run down five checks. First, the percentage: is it the rate for this category, this seller tier, and this moment — or is it the page’s 13.25% example still sitting in the box from the last calculation? An example left in place is the most common source of a wrong keep figure, and it is wrong by exactly the difference between the example rate and your real one, on every sale. Second, the price: does the sale-price box contain the item price alone, or the item plus postage, and which does your fee terms say the percentage applies to? Third, the per-order fee: is the $0.30 in the box your actual per-order fee for this listing, or the example’s? Fourth, the extra lines: payment processing, listing and other fees, and shipping shortfall — have you entered each one that applies, or is one hiding inside a lump sum you forgot to split? Fifth, the costs beyond the page: item cost, acquisition, packaging, postage paid, time, and tax — have you subtracted them from the keep figure before calling anything profit?

If all five checks pass, the keep figure is a reliable statement of what the marketplace’s counted fees leave you, at the rate you entered, for the sale you described. If any check fails, the keep figure is reliable only as arithmetic on the wrong inputs — which is a precise way of being wrong. The page’s design, with every fee on its own line and the effective rate shown beside the total, exists to make those checks easy: read the lines, compare each one with your listing terms and your books, and correct the line that disagrees. A fee breakdown that hides its lines cannot be checked; a breakdown that shows them invites checking, and checking is the whole difference between a seller who knows their margin and one who discovers it at tax time.

Pricing backwards from the amount you want to keep is the most practical use of this calculator, and the formula runs in reverse cleanly. Suppose you want to keep $100 from a sale at the example terms of 13.25% plus a $0.30 per-order fee, with no extra lines. The price that keeps $100 is ($100 + $0.30) ÷ (1 − 0.1325) = $115.62 before rounding — and the calculator confirms the neighbourhood: a $115.61 sale at those terms keeps $99.99 after $15.62 in fees, a cent short of the target through rounding alone. The general rule is: price equals (amount you want to keep plus all fixed fees) divided by (one minus the percentage fee), with each extra line either added to the fixed fees or, if it is itself a percentage, folded into the percentage. Sellers who price by adding the fee percentage to their target — $100 plus 13.25% is $113.25 — underprice every sale, because the fee is charged on the higher price, not on the target: $113.25 at 13.25% plus $0.30 leaves only $97.95, not $100. Price from the keep figure backwards, and the fee stops eating the margin you thought you had built in.

Across a month of sales, the same per-sale figures scale exactly, which makes the calculator a monthly planning tool as well as a per-sale one. Ten sales at the default terms — ten $100 sales at the example 13.25% plus $0.30 each — give total fees of $135.50 and $864.50 kept, ten times the single sale’s $13.55 and $86.45. A hundred such sales give $1,355 in fees and $8,645 kept. The scaling is exact only while every sale shares the same terms; a month mixing categories, prices and extra lines must be totalled sale by sale, with each sale’s effective rate, because the per-order fee’s dilution and the extra lines’ weight differ across sale sizes. But the discipline scales even when the arithmetic does not simplify: total the fees line by line across the month — final-value fees, per-order fees, processing, listing, shipping shortfalls — and the month’s largest line is the month’s largest cost, which is where any effort to reduce fees should go first. A seller whose month is dominated by shipping shortfalls has a postage problem, not a fee-percentage problem, and no change of percentage will fix it.

Two questions this page does not answer, stated so that they are not mistaken for answered. The first is refunds and returns: whether fees are credited, in whole or in part, when a sale is refunded depends on the marketplace’s current terms for the category and the circumstances, which this page does not reproduce — check your seller terms for the return in question before assuming the keep figure reverses. The second is international and currency questions: sales in other currencies, cross-border fees, and currency conversion are outside this calculator’s inputs entirely, and a keep figure computed in dollars from a dollar price says nothing about what a sale priced in another currency will net. Both omissions follow the same principle as the rate itself: this page computes exactly from the inputs you enter and asserts nothing about terms it does not reproduce. Where a term matters to your sale and is not an input here, your listing terms — not this page — are the source of truth, and the keep figure should be treated as provisional until that term is checked.

One last discipline: re-check the rate before every listing, not once a season. Fee schedules change, categories are reclassified, and seller terms vary with standing and volume — a rate that was right for last month’s listing in one category may be wrong for this month’s listing in another, and the calculator will faithfully compute the wrong fee from the stale rate without complaint. The check costs a minute against your own listing terms; the cost of skipping it is every fee figure on the listing being wrong by the difference between the old rate and the new one, compounded across every sale at that rate. This page’s example rate is a starting value, deliberately, because a starting value that is visibly an example is safer than a schedule that looks authoritative and goes stale.
