Worked Calculation Examples

ScenarioResultCalculation Step
$100 chargeFee $3.20, net payout $96.80Fee = (100 × 0.029) + 0.30 = $3.20. Net = 100 − 3.20 = $96.80 (3.2% effective rate).
$10 charge (small transaction)Fee $0.59, net payout $9.41Fee = (10 × 0.029) + 0.30 = 0.29 + 0.30 = $0.59. Net = 10 − 0.59 = $9.41 - a 5.9% effective rate, nearly double the $100 example, since the flat $0.30 weighs much more heavily on a small sale.

How Stripe Fees Are Calculated

Stripe's standard pricing charges a percentage of the transaction (commonly around 2.9% for online card payments in the US) plus a small flat fee (commonly $0.30) per successful charge. Fee = (amount x percentage) + flat fee, and net payout = amount - fee.

Why the Flat Fee Hurts Small Transactions More

Because the flat fee stays the same regardless of transaction size, it represents a much larger percentage impact on small transactions than large ones - a $1 sale loses a much bigger share of revenue to the flat fee alone than a $100 sale does, which matters for businesses selling low-priced items.

Frequently Asked Questions

How do you calculate Stripe fees?

Multiply the transaction amount by Stripe's percentage rate (commonly around 2.9% for standard online card payments), then add the flat per-transaction fee (commonly $0.30) to get the total fee.

Why do small transactions lose a bigger percentage to fees?

The flat fee portion stays constant regardless of transaction size, so it represents a larger relative cost on small transactions compared to larger ones.

Do Stripe fees vary by payment type or country?

Yes - rates can differ for international cards, currency conversion, and specific payment methods, so actual fees may vary from the standard published rate depending on the transaction details.

Calculate Stripe Fee metrics for ecommerce, SaaS, marketing, and operations. It is designed for fast browser-based calculations without sign-up, downloads, or manual spreadsheet setup.

What formula does this stripe fee use?

The formula is: Fee = (Amount × 2.9%) + $0.30; Net Payout = Amount − Fee. Stripe, founded in 2010 by brothers Patrick and John Collison, popularized this simple, transparent percentage-plus-flat-fee pricing model as a deliberate contrast to the often opaque, negotiated merchant processing rates that dominated the payments industry before it, part of what made Stripe's developer-friendly approach to online payments so influential in the 2010s fintech boom.
