Why Did My Stripe Fees Increase?

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.

1. More International Cards

Stripe charges an additional 1.5% for international cards (cards issued outside your country). If your customer mix has shifted toward international buyers — through SEO, new markets, or paid ads — your effective rate rises automatically.

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 a 1% conversion fee when charging in a currency other than your settlement currency. If you recently started selling globally, this is likely contributing.

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.
