About Marketplace Fee Cost

Aggregates every marketplace charge into one effective rate against gross merchandise value. Fixed subscription and per-order fees do not scale with revenue, which means the effective rate falls as volume grows - and is why low-volume sellers pay a much higher real percentage than the headline commission.

Formulas

Total fees

Fees = GMV x (commission + processing) + subscription + orders x per-order fee

Effective rate

Rate % = total fees / GMV x 100

Assumptions and limits

  • The result is derived only from the 6 inputs listed above. Anything not among them is not part of the calculation.
  • In particular, this calculator does not take inflation, tax or compounding frequency into account.
  • Figures are rounded for display to 2 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.

How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.

Frequently Asked Questions

Why does the effective rate differ from the commission rate?

Because processing, subscription and per-order fees are added on top. A 12% commission commonly becomes a 16-18% effective rate at modest volume.

Is a subscription plan worth it?

Only above the volume where the reduced commission saves more than the subscription costs. Model both plans here and compare the effective rates.
