Why international cards matter
A SaaS product can look profitable on domestic card rates and then lose margin as customers arrive from more countries. International cards can change the blended fee enough to alter the provider decision.

International Card Fee Calculator for SaaS
Estimate how cross-border and international card assumptions change the payment provider comparison for a global SaaS business.
Use blended assumptions
Do not model one perfect customer. Use an estimated international card share, average order value, refund rate, and chargeback rate. The blended result is closer to what a real SaaS business feels in monthly revenue.
Global SaaS tradeoff
Payment processors can be efficient when you control the whole stack, but global sales also create tax, invoice, support, and dispute work. That is why merchant-of-record providers are often part of international card fee comparisons.
What to test first
Run scenarios at 0%, 25%, 50%, and 75% international card share. If the winner changes across those scenarios, your customer geography is a real decision variable rather than a footnote.
Run the numbers
The main calculator has an international card share slider for comparing providers under the same assumptions.

International Card Fee FAQ
What international card share should I use?
If you do not know yet, start with 25% or 35%, then rerun the calculator when real customer geography appears in your payment data.
Can international customers make MoR providers more attractive?
Yes. The raw fee may be higher, but bundled tax, invoicing, and support can become more valuable as customer geography becomes more complex.
Should I split domestic and international revenue?
For a rough planning pass, the slider is enough. For a detailed finance model, split revenue by market, card type, currency, refund rate, and tax treatment.
