Marketplace Commission Calculator
Marketplace take rate, estimated.
Calculate marketplace total fees from commission, payment processing, listing, and advertising percentages applied to the sale price.
What this tool does
Net revenue from a marketplace sale equals the sale price minus all associated fees: commission percentage, payment processing fee percentage, listing fee, and advertising spend as a percentage of the sale. This calculator takes your sale price and each fee component, then shows the total fees deducted and the net revenue you retain. The result illustrates your actual take-home amount and your overall take rate—the percentage of each sale consumed by fees. Commission percentage and payment fees typically drive the largest impact on net proceeds, though listing fees and advertising costs compound the effect. Results assume fees are calculated as stated and apply consistently; they don't account for refunds, chargebacks, or variable fee structures that may apply to different sale amounts or seller tiers. Use this to model different pricing or fee scenarios.
Quick answer: with the default values, the result is $12.50 (Total Marketplace Fees). Adjust the values below for your own figures.

Marketplace fees stack: a commission or referral fee on the sale price, payment processing (sometimes bundled into that commission, sometimes charged separately), a per-item listing fee on some platforms, and advertising where it is used. Platforms bundle these differently — one folds processing into its commission, another charges it on top, a third adds a fixed per-order amount — so comparing headline commission rates alone understates the gap between them. Total take rate is the comparable number.
50 sale × 15% commission + 3% payment + 5% ads + 1 listing = 7.50 + 1.50 + 2.50 + 1 = 12.50 total fees, a 25% take rate. Net revenue 37.50. At that take rate, gross margin has to cover the fees and everything after them — packaging, shipping, returns and overhead — before anything is left.
Sellers pull on a few levers: higher-margin or differentiated products, bundles that lift order value above the fixed per-item fees, own-brand products where the margin is set in-house, and ad spend, which adds to the take rate whenever it is used. Marketplaces supply discovery and buyer trust; an owned storefront trades those for lower fees and traffic funded some other way.
Quick example
With sale price of 50, commission of 15%, payment fee of 3%, ads of 5% and listing fee of 1, the result is 12.50.
Which inputs matter most
You enter Sale Price, Commission %, Payment Fee %, Listing Fee, and Ads % of Sale.
What's happening under the hood
Total fees = sale × (commission + payment + ads %) + listing fee. Net = sale - fees. Take rate = fees ÷ sale × 100.
Running it across a product range
Fee percentages stay the same across a catalogue, but the fixed listing fee does not — it lands harder on low-priced items. Running a cheap item and an expensive one through the same fee settings shows how much of the take rate is fixed cost rather than percentage.
£50 × (15% + 3% + 5%) + £1 = $12.50.
Inputs
| Net Revenue | $37.50 |
|---|---|

Sources & Methodology
Methodology
This calculator computes the total fees a seller incurs on a marketplace transaction by summing three percentage-based costs applied to the sale price—commission, payment processing, and advertising—then adding any fixed listing fee. The formula treats each cost component as independent and applies them additively. It then derives the take rate by dividing total fees by the sale price and expressing the result as a percentage. The model assumes a flat-rate fee structure with no volume discounts, no variable payment fees based on payment method, and no changes to fees across transaction types. It does not account for refunds, chargebacks, seller reimbursements, the compounding effect of fees on net proceeds, any fixed per-transaction amount a payment processor charges alongside its percentage, or the practice on some platforms of applying the percentage to sale price plus shipping rather than to the sale price alone. Where a marketplace already includes processing inside its commission, entering a separate payment fee would count it twice.
