Fees add up in layers

Most selling platforms charge more than one fee. A marketplace may take a percentage commission, a payment processor takes a second percentage plus a fixed amount per transaction, and some also charge listing fees. This calculator lets you enter two percentage fees and one fixed fee so you can reproduce most combinations.

The preset menu fills in example fees for Stripe, PayPal checkout, Etsy in the US and Gumroad. They are examples only: platforms change their pricing, and fees differ by country, plan and payment method. Always check the platform’s current fee page before relying on a preset.

The effect of the fixed fee

A small fixed fee hurts low prices far more than high ones. A $0.30 fixed fee on a $5 sale is a 6% cost on its own, on top of the percentage. The effective fee rate in the results shows the total fees as a percentage of the sale price, which is the figure to compare between platforms.

Pricing to protect your net

Enter a desired net amount to see the price you need to charge. The formula solves for the price after percentage fees and the fixed fee, so you do not guess. Combine it with the profit margin calculator to see how fees and costs affect your margin.

Frequently asked questions

How do I calculate marketplace fees?

Add the percentage fees together, multiply by the sale price, then add any fixed fee per transaction. Subtract the total from the price to get your net.

Are the presets up to date?

They are examples. Check each platform’s official fee page, since pricing, regions and plans change.

How do I price to receive an exact amount?

Enter your desired net. The calculator divides the net plus the fixed fee by one minus the total percentage.

Do these fees include taxes?

No. Sales tax, VAT and income tax are separate.

What is the effective fee on a $5 sale at 2.9% + $0.30?

2.9% of $5 is $0.145, plus $0.30 gives $0.445, so the effective fee rate is 8.9%. Small prices feel fixed fees much more.

How do I price a product to cover platform fees?

Enter the net amount you want to keep and the calculator finds the selling price that leaves it after all fees.

Do platform fees include sales tax?

No. Sales tax and income tax are separate from platform and payment fees.
