Stripe Fees Calculator: Estimate Monthly Fees
Free Stripe fees calculator for monthly card volume and average charge size — including how much Stripe charges per transaction on the published 2.9% + $0.30 rate. Then compare that estimate with your actual effective rate from a Balance CSV, where international cards, refunds, small charges, and add-ons can push the real number higher.
Stripe Fee Auditor is built for SaaS, ecommerce, subscription, and marketplace teams that need a Stripe fee calculator based on actual Balance CSV exports instead of averages.

Common questions
How much does Stripe charge per transaction?
For many US online card payments, Stripe's published rate is 2.9% + $0.30 per successful charge. On a $100 domestic card payment that is about $3.20 (3.2% effective). International cards, currency conversion, refunds, and small tickets can push the blended rate higher — use the calculator above for your mix, then upload a Balance CSV to see your real rate.
Is this a Stripe fee estimator or a real calculator?
The on-page Stripe fees calculator estimates fees from public pricing. Stripe Fee Auditor calculates your real effective Stripe fee rate from your Balance Transactions CSV, so you can compare the estimate with actual numbers.
How do I estimate monthly Stripe fees?
Enter your monthly card volume and average charge amount. The calculator estimates how many transactions you processed, applies 2.9% plus $0.30 per charge, and shows the effective percentage for that mix.
What file do I need to calculate my Stripe effective fee rate?
You need the Stripe Balance Transactions CSV export. It includes the transaction amount, fee, net amount, currency, type, and timestamp needed for an accurate fee analysis.
Why can my effective Stripe rate be higher than the published rate?
International cards, currency conversion, refunds, Radar charges, disputes, and micro-transactions can all push your blended effective rate above Stripe's standard published rate.
