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.

Example Scenario

£50 × (15% + 3% + 5%) + £1 = $12.50.

Inputs

Sale Price:£50
Commission %:15%
Payment Fee %:3%
Listing Fee:£1
Ads % of Sale:5%

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.

Frequently Asked Questions

How do marketplace fee structures differ?
The main difference between platforms is what the headline percentage already includes. Some marketplaces fold payment processing into a single referral or final-value percentage, so adding a separate processing fee on top double-counts it. Others charge processing separately, and some add a fixed per-order amount as well. A per-item listing fee applies on some platforms and not others, and advertising is optional everywhere. Published rates also differ by marketplace region, category and seller tier, so the schedule attached to your own account is the figure to enter here.
Can I sell without ads?
Advertising is optional on most platforms, though organic visibility and ad spend are linked: sponsored placements sit above organic results, and ranking systems that weight sales velocity are indirectly influenced by ads. Sellers in narrow niches with less competition report less ad spend than those in crowded categories. The ads input accepts any level including zero, so the take rate with and without advertising can be compared directly.
What moves the take rate?
Fixed per-item fees fall as a share of the sale when order value rises, which is why bundling moves the take rate more on cheap items than expensive ones. Some marketplaces publish lower commission tiers for particular categories or volumes. Fulfilment choice changes the fee mix where the platform charges for it separately. Higher click-through on a listing lowers the ad cost per sale, which reduces the ads component of the take rate.
Marketplace vs own site?
A marketplace supplies traffic and buyer trust in exchange for a take rate. An owned storefront carries payment processing but no marketplace commission, and its traffic is funded through ads, search or an existing audience. The comparison turns on acquisition cost: where acquisition cost per sale on an owned site sits below the marketplace take on the same order value, the owned site retains more per order; where it sits above, the marketplace does. This calculator covers the marketplace side of that comparison.
