Application Fee

An application fee is the amount a Stripe Connect platform collects from a payment that one of its connected accounts processes. It's how a marketplace or platform monetizes the transactions it enables — the commission on top of the sale.

How the fee is set and collected

The platform sets the fee per payment using the application_fee_amount parameter, expressed as a fixed amount in the transaction's currency rather than a percentage. The platform calculates whatever cut it wants — a flat rate, a percentage of the total, or a tiered rule — and passes the resulting amount.

Where the fee lands depends on the charge model:

• With direct charges, the charge is created on the connected account and the application_fee_amount is pulled to the platform account.
• With destination charges, the platform charges the customer and uses the transfer amount (or the application fee) to decide how much stays with the platform versus the seller.

For example, on a $100 sale with a $15 application fee, the platform's gross take is $15, less Stripe's processing fee on the transaction depending on how the integration is structured.

Why it matters

The application fee is the platform's core revenue line, so tracking it separately from gross volume is essential. A marketplace can move millions in gross payment volume while earning only a small slice — the sum of its application fees. Reporting that conflates the two makes the business look far larger than the money it actually keeps, so the application-fee total, not gross volume, is the number that maps to platform revenue.
