About This Tool
The Stripe Fee Calculator handles the two most common payment processing math problems: calculating net payout from a gross charge, and calculating the gross amount needed to receive a target net. Stripe's standard US rate of 2.9% + $0.30 per transaction is the most common payment processing fee in ecommerce, and understanding how it scales with ticket size matters for pricing and margin planning.
The Flat Fee Problem on Small Transactions
Stripe's $0.30 flat fee is the dominant cost on small transactions. A $5 charge nets $4.55 (9.0% effective fee). A $50 charge nets $48.25 (3.5%). A $500 charge nets $485.20 (3.0%). The effective rate asymptotically approaches 2.9% but only at large ticket sizes. This is why digital tip jars, micropayment platforms, and small-value subscriptions struggle with payment processing — flat fees crush them.
Grossing Up: When You Need a Target Net
If you have a fixed payout obligation (event ticket payout, fundraiser pass-through, marketplace seller payment), you need to charge enough to cover fees and still net the target. The gross-up formula: Charge = (Target Net + Flat Fee) ÷ (1 - Fee%). To net $100 exactly, charge $103.30 ($100.30 / 0.971). Build this into your checkout math whenever you have downstream payout obligations.
International Card Surcharges
Stripe charges an additional 1.5% for international cards in the US, plus 1% for currency conversion if applicable. A $100 charge on an international card with conversion costs roughly 5.4% in fees ($94.60 net) instead of 3.2% ($96.80 net). Cross-border ecommerce should price this in or use Stripe's automatic currency conversion to charge in the buyer's local currency, which moves conversion cost to the buyer.
Volume Discounts and Negotiation
Stripe offers custom pricing above $1M-$2M monthly volume. Discounts of 0.2-0.5% on the percentage rate are typical. The flat $0.30 portion is rarely negotiable. Brands processing $5M+/year should always ask. Competitors like Adyen, Braintree, and direct interchange-plus processors often beat Stripe rates at scale but require more integration work.
