How US Stripe pricing breaks down
The 2.9% + 30¢ headline rate applies to online card transactions where the card was issued in the United States. That covers the typical SaaS, e-commerce, and donation transactions. Cards from outside the US — even if your business is US-based and your customer is buying in USD — incur the international rate of 4.4% + 30¢.
On top of the base rate, several additive fees can apply: Stripe Tax (0.5%) if you’ve enabled it; Stripe Billing (0.5%) if the charge is a recurring subscription; Radar for Fraud Teams ($0.05 per screen) if you’ve enabled Radar; and a 1.5% Connect surcharge if you’re using Express or Custom Connect.
The $0.30 fixed component is what trips up reverse-calculations. To net $96.80, you don’t simply charge $99.70 — you charge $100 ((96.80 + 0.30) / (1 − 0.029) = $100 exactly). Use the reverse mode of this calculator to get the math right automatically.
