How We Calculate eBay Fees, Proceeds and Profit
An estimate should be easy to follow. Here is what we calculate, where the rules come from and what we leave out.
Start with clear definitions
| Input or result | Meaning |
|---|---|
| Sale price | Price of one item. Quantity, if used, multiplies this amount. |
| Buyer-paid shipping | Shipping and handling collected for the whole order. Part of seller revenue. |
| Sales tax | Buyer sales tax for the whole order. Included in the applicable fee base, excluded from revenue. |
| Item cost | Your acquisition cost per item; multiplied by quantity. |
| Actual shipping, packaging & other | Costs for the whole order, not per item. |
| Seller proceeds | Sale revenue less estimated platform and advertising fees, before item and fulfillment costs. |
Category rules, not one flat percentage
We select a fee group and Store schedule. No Store and Starter use the standard schedule for the supported groups. Basic, Premium, Anchor and Enterprise use the higher-Store schedule.
Marginal bands charge one rate on the amount up to a threshold and another rate on the excess. Whole-amount rules select a rate using the threshold and apply that rate to the entire per-item amount. Bullion, jewelry, handbags and athletic shoes have whole-amount behavior in this release.
The ordinary fee base is item price plus allocated buyer shipping and buyer sales tax. For identical items in one checkout with one shipping method, shipping and tax are allocated evenly in cents, with remainder cents assigned to the first items. We calculate the percentage fee per item and add the order charge once.
The order charge uses the total buyer order amount: $0.30 at $10 or less and $0.40 above $10. The supported athletic-shoe rule waives it when every per-item total is at least $150. Mixed-category orders and Authenticity Guarantee shipping are not supported.
An optional fee-base shipping override handles the cheapest-domestic-option exception. It cannot exceed buyer-paid shipping and does not change revenue or the General advertising fee base. Read the shipping explanation.
Proceeds, profit, margin and ROI
Fees = category percentage fee + per-order fee + applicable ads + entered insertion & other fees
Seller proceeds = revenue − fees
Net profit = seller proceeds − item cost × quantity − actual shipping − packaging & other costs
Profit margin = net profit ÷ revenue × 100
ROI = net profit ÷ entered item, shipping, packaging & other costs × 100
Tax is absent from the revenue line. We show N/A when a ratio’s denominator is zero, including zero total costs for ROI. Negative profit is shown directly, rather than hidden or clamped to zero.
General advertising uses the entered rate on the total sale including buyer shipping and tax, only when you confirm an attributed sale. Priority uses your entered actual click spend. Neither strategy is predicted by the tool.
Working backward from a target
Target price supports one item and either a profit amount or a margin. The search evaluates the separate rate regions, including whole-amount threshold changes, and checks prices in cents around a possible solution. It can therefore find a lower feasible price on the other side of a fee threshold.
Tax is a fixed dollar input during this search. This is not a state tax engine: after changing the price, update your tax amount and recalculate. Targets too close to a maximum attainable margin, unsupported dates and unattainable prices receive an explicit error.
Buyer shipping, costs, insertion fees and actual Priority spend remain fixed during target pricing. No future clicks or orders are predicted. Prices above $1,000,000 per item are outside the search.
Find a target sale price ↗Rounding and reconciliation
Inputs are converted to integer cents. We round the calculated percentage fee for each item to the nearest cent and round a General ad charge separately, then add the fee lines. Ratios are displayed to two decimal places. This is our documented estimation convention, not a claim that every eBay invoice uses identical allocation and rounding.
Small differences can arise from allocation, refunds, fee credits, taxes on seller fees and actual order adjustments. Compare line items against your statement before relying on a price decision.
Supported scope & exclusions
Supported: US-registered sellers, US domestic sales in USD, the 15 listed fee groups, supported Store schedules, and one item or identical-item orders of up to 100 items. Fixed-price and ordinary auction sales share the supported final value schedule; listing-format charges must be entered manually.
Rules verified: 2026-10-11. Version: us-2026-10-11.1. This snapshot accepts that calculation date only. Earlier and later fee periods have not been verified. The snapshot start is not a claim about the original effective date of every eBay fee. We do not provide historical fee reconstruction.
Not supported: international buyers or shipments, currency conversion, eBay Live, motor vehicles, real estate, NFTs, Authenticity Guarantee shipping, mixed-category or mixed-price orders, and unlisted fee categories. Selecting an unsupported case stops the estimate.
Not inferred: insertion allowances, listing upgrades, seller-performance surcharges, taxes on seller fees, international charges, fee credits, refunds, payment disputes and Store subscription allocations. Add known amounts in the appropriate fields. An unentered charge is excluded, not certified to be zero.
We do not retrieve your eBay account, orders, seller level, tax location or attribution history. Your inputs remain in your browser; local saving is opt-in. Read the privacy policy.
Sources & corrections
Official rules take precedence over this tool. We record rule checks and actual product changes in the update log. If a line seems wrong, report the calculation without sending private buyer or order information.
