Short answer
The quick math
Using the editable US domestic-card assumption of 2.9% + $0.30, a $120 Stripe charge has an estimated fee of about $3.78 and a net of about $116.22 before any manual-entry, international-card, or currency-conversion add-ons.
Assumptions used
- $120 charge amount
- 2.9% base card fee
- $0.30 fixed fee
- No manual-entry add-on
- No international-card add-on
- No currency-conversion add-on
Use it before you decide
- Run the base domestic-card estimate first.
- Add manual-entry, international-card, or currency-conversion percentages only if they apply.
- Test subscriptions and one-time payments separately if the checkout mix differs.
