Rounding Rules for Stripe Fees

Question

How does Stripe round its fees?

Answer

Stripe rounds the Stripe fee to the nearest unit (e.g., cents). For example, if the fee is 0.025, Stripe will round up to 0.03. If the fee is 0.024, Stripe will round down to 0.02.

ACH fees have a floor, so that if we were to round the fee to 0, we would instead round it to 1 cent.
