Stripe Blended Rate Calculator: Finding Your True Payment Processing Cost
Stripe's advertised rate is 2.9% + $0.30. Your actual blended rate — what you really pay across all transactions — is almost certainly higher. Here's the formula, the factors that inflate it, and how to calculate yours.

What is a blended rate?
Your blended rate (also called effective rate) is the total fees you paid divided by your total charge volume over a period. It's a single number that captures everything — percentage fees, fixed fees, international surcharges, currency conversion, and any other charges.
Unlike the advertised rate, which applies to one idealized transaction type, your blended rate reflects your actual mix of customers, card types, geographies, and transaction sizes.
Snippet answer
Stripe blended rate is the real percentage of processed volume paid in Stripe fees: total fees divided by total charge volume. It is usually more useful than the advertised card rate when you want to understand an actual month of payments.
The formula
Example
vs. advertised 2.9% — this business is paying 10% more than the stated rate.
How to calculate it manually
- 1
Export your Stripe Balance CSV (Itemized)
Go to Dashboard → Reporting → Reports → Balance summary → Export → choose "Itemized". See our full export guide for details.
- 2
Sum the "amount" column for charge rows
Filter the CSV where the "type" column equals "charge". Sum the "amount" column. This is your total charge volume (in cents — divide by 100 for dollars).
- 3
Sum the "fee" column for those same rows
Sum the "fee" column for charge rows only. This is total fees paid on charges (also in cents).
- 4
Apply the formula
(Total fees / Total charge volume) × 100 = your blended rate as a percentage.
What inflates your blended rate
Multiple factors push your real rate above the advertised 2.9%:
International cards
+1.5% per intl. chargeCards issued outside your Stripe account's country add 1.5% per transaction.
Fixed fee on small transactions
+3–30% on small chargesThe $0.30 fixed fee represents 6% of a $5 charge — pushing effective rate above 9%.
Currency conversion
~+1% per conversionWhen Stripe converts between currencies, it typically adds about 1% on top of processing (confirm your pricing tier).
Stripe Billing fee
+0.7% or flat feeStripe Billing adds 0.7% of billing volume on the pay-as-you-go plan on top of card processing — or you can use fixed annual plans starting around $620/month instead of the percentage.
Manually entered cards
+0.5%Cards typed in by staff (manual / MOTO entry) cost an extra 0.5% on top of standard card rates — easy to miss for B2B phone orders.
Refunds (fee not returned)
+0.1–0.5% blendedStripe keeps the processing fee when you issue a refund, increasing your net cost.
Dispute fees
VariableEach dispute costs $15 regardless of outcome. A 0.5% dispute rate adds ~$0.75/transaction.
What's a healthy blended rate?
There's no universal benchmark — it depends on your customer mix and transaction sizes:
- US-only SaaS, domestic cards, avg transaction $50+2.9–3.1%
- US-only SaaS with Stripe Billing3.6–4.5%
- Mixed US/international, SaaS or subscriptions3.2–3.8%
- Majority international customers4.0–5.0%+
- Low average transaction value (under $20)4.0–6.0%+
If your rate is above the expected range for your profile, something specific is driving it — usually international cards or small transactions. Both are identifiable from your Balance CSV.
Month-by-month tracking matters
Your blended rate isn't static. A spike in one month usually has a specific cause: a marketing campaign that drove international traffic, a product launch with small intro-priced transactions, or a batch of refunds.
Tracking month-by-month lets you diagnose these spikes and respond — either by adjusting payment methods for affected customers, or at minimum understanding why your fees increased so you're not surprised at tax time.
Common questions
What is a Stripe blended rate?
A Stripe blended rate is total Stripe fees divided by total charge volume across a period. It blends different payment types, fixed fees, international cards, refunds, and add-on fees into one real-world percentage.
Why is my blended rate higher than 2.9%?
Your blended rate can be higher than 2.9% because the fixed $0.30 fee is large on small charges, international cards add cross-border fees, currency conversion can add cost, and refunds or disputes can raise all-in fees.
Should I use charge fees or all Stripe fees?
Use charge fees to measure card processing rate. Use all Stripe fees to measure all-in Stripe cost. Both are useful, but they answer different questions.
