Stripe Blended Rate: Formula and Month-to-Month Tracking
6 min read · Stripe Fees · Updated Aug 2026
There is no magic “blended rate calculator” separate from dividing two columns. The Stripe fee calculator estimates one published-price charge. Blended rate is what your month did. If you want the definition of effective rate in one paragraph, that is the sibling article. This page is the tracking habit.
Formula I paste into the sheet
blended % = (sum of fees) / (sum of charge amounts) × 100. Use the same date filter on both. If volume is $50,000 and fees are $1,850, you paid 3.70%. I keep a second column for all-in fees so a Radar bill cannot hide inside “processing.”
Advertised 2.9% is one card type. Blended is the pile: ticket sizes, countries, refunds, extras. Calling them the same thing is how people email Stripe and get a pricing PDF back.
What usually inflates the number
Fixed $0.30 on a lot of small rows. International + conversion. Refunds that do not return the original processing fee. Dispute fees. Product lines that are not cards. I have seen a “quiet” month jump 40 bps because one enterprise invoice refunded and kept the fee.
A range, not a trophy number
Mostly US cards, $50+ tickets: high-3s processing is a smell. Heavy EU/UK cards: 4% can be the honest run rate. There is no universal “healthy blended rate.” Compare you vs you last month, same definition.
Export itemized Balance, one tab per month. Or upload the CSV and read the monthly chart. Recalculating by hand every quarter is how the number rots.

Common questions
What is a Stripe blended rate?
Total Stripe fees divided by charge volume across a period. It folds in ticket size, international cards, refunds, and extra fee lines.
Why is my blended rate higher than 2.9%?
Because 2.9% + $0.30 is a sticker for one domestic card. Fixed fees, cross-border, conversion, refunds, and add-ons change the month.
Should I use charge fees or all Stripe fees?
Charge fees for processing rate. All Stripe fees for all-in cost. Report both or you will optimize the wrong pile.
