Definition and method

What this calculator answers

Add the commissions, listing charges and fixed order fees that actually apply to see the cost for the marketplace activity entered.

Commission

Commission cost = marketplace sales × the commission percentage entered for that activity.

Worked example: your figures

The interactive result above is the worked example. Change any input and the same deterministic engine recomputes the answer; this page does not insert a generic example business or silently treat example values as a benchmark.

  • No market benchmark or outcome is silently inserted by this page.

Frequently asked questions

What does the marketplace charge?

Marketplace fee structures vary by platform, category, geography and seller plan. Enter the commission, listing and fixed-order charges that actually apply to the activity being modelled; do not assume a standard marketplace fee stack.

Marketplace Fee Cost

How do I capture the actual rate?

Pull last month's invoice from the marketplace — Etsy and eBay statement exports total commissions, insertion fees and transaction fees separately. Enter each line so the calculator reproduces what the marketplace actually charged.

Marketplace Fee Cost

What if I sell on multiple marketplaces?

Run this calculator for each platform and sum the monthly fees — or enter a volume-weighted blended rate if you only want a single back-of-napkin number. The per-platform view is sharper for raising listings on the more expensive channel.

Marketplace Fee Cost

When is a marketplace worth the fee?

Use the calculator result for the inputs entered and keep any market-response or operating recommendation separate from the deterministic calculation. Support that additional assumption with the business’s own evidence or an explicitly labelled scenario.
