How can I tell what caused the increase?

Export your itemized Stripe Balance CSV and compare this month to prior months. Check international card share, average transaction size, refund rows, dispute rows, and non-charge Stripe fee rows.

Can Stripe fees increase even if my pricing did not change?

Yes. Your Stripe pricing can stay the same while your effective rate rises because customer geography, transaction size, refunds, disputes, or add-on usage changed.

Why Did My Stripe Fees Increase This Month?

Q: Why did my Stripe fees increase?

Stripe fees usually increase because your payment mix changed: more international cards, lower average charge size, currency conversion, disputes, refunds, or extra Stripe products such as Billing, Radar, or Tax.

If your Stripe effective fee rate has climbed over the past few months, you're not alone. Many businesses notice a gradual increase without a clear reason. Here are the most common causes.

Short answer

Your Stripe fees usually increase because your transaction mix changed, not because one obvious setting changed. International cards, smaller charges, refunds, disputes, currency conversion, and add-on products can all raise the effective rate.

1. More International Cards

Stripe charges an additional 1.5% for international cards (cards issued outside your country). If the charge currency differs from your settlement currency, conversion fees (often around 1%) stack on top — a common worst-case mix can approach ~5.7% of the charge before fixed fees on a $100 example (see our international fees guide). If your customer mix has shifted toward international buyers, your effective rate rises.

2. More American Express Transactions

Amex cards have higher interchange fees. Standard Stripe rate for Amex is 2.9% + $0.30, same as Visa/Mastercard — but the underlying interchange is higher, which can affect your costs if you're on a custom pricing plan.

3. Smaller Average Transaction Size

The fixed $0.30 per transaction matters more for small payments. A $5 charge has an effective rate of 8.9% (2.9% + $0.30 = $0.445 on $5.00), while a $100 charge is just 3.2%. If your average order value dropped, your effective rate went up.

4. Increased Dispute Rate

Each dispute costs $15. Even a small increase in dispute frequency can meaningfully raise total fees, especially if your average transaction size is moderate.

5. Currency Conversion

Stripe adds roughly a 1% conversion fee when charging in a currency other than your settlement currency. If you recently started selling globally, this is likely contributing — especially alongside international cards.

6. Stripe Billing Usage

If you use Stripe's Billing product for subscriptions and invoicing, pay-as-you-go pricing commonly adds about 0.7% of billing volume on top of card or ACH processing. Fixed annual Billing plans start around $620/month instead of that percentage — growing recurring revenue raises costs differently depending on which model you chose.

How to Diagnose Your Fees

The fastest way to find the cause is to analyze your Stripe Balance CSV. Export it from Stripe → Reports → Balance, and upload it to Stripe Fee Auditor for an instant breakdown of your effective rate and top cost drivers.
