Core guide

A seller-friendly glossary page explaining marketplace commission, fee base, editable assumptions, and how commission changes margin.

Definition

Marketplace commission is the percentage or service-fee layer a platform takes from an order. The exact label changes by marketplace, seller program, and category, but the seller decision is the same: how much of the order value is kept by the platform before payout.

Why fee base matters

A commission rate is only useful when you know the base it applies to. Some sellers model it against list price, while real order math may be closer to price after seller discount, program voucher, or other marketplace rules.

  • Start with the actual order price customers pay.
  • Separate seller-funded discounts from platform-funded incentives.
  • Keep commission editable when the platform publishes ranges instead of one fixed number.

How to use it in the calculator

Enter the commission or admin-fee assumption as a separate fee line, then compare payout, break-even price, and remaining ad budget. This keeps the decision operational instead of turning it into a generic article answer.

The order value the fee is calculated from.

Why it matters

A wrong base makes every downstream margin estimate too optimistic.

Program overlap

Input

Promo, voucher, affiliate, or shipping programs around the same order.

Why it matters

These layers explain why simple commission math often fails.

FAQ

Is marketplace commission the same as profit margin?

No. Commission is only one cost line. Profit margin also depends on product cost, packaging, shipping subsidy, discounts, payment fees, and ads.

Should I use the low or high end of a marketplace fee range?

Use the value that matches your actual seller account and category. If you are unsure, model a conservative high case before scaling ads.

Why does this page not publish one universal commission table?

Marketplace fee tables change and can depend on category or seller program. The calculator keeps the fee editable so the page stays useful when the rules move.
