Model how international cards, currency conversion, order value, refunds, and chargebacks can change the fee gap between Stripe and merchant-of-record providers.
A SaaS product can look profitable on domestic card assumptions and then lose margin when more customers pay from other countries. International card share is one of the fastest ways for the cheapest-looking processor to become less obvious.
Do not compare only the base percentage. Use monthly revenue, monthly orders, international card share, refunds, and chargebacks to estimate the blended fee drag on take-home revenue.
Stripe can be a strong choice when you want direct checkout control, have finance operations covered, and understand the extra tax, invoice, fraud, and dispute work that sits outside card processing.
Paddle, Lemon Squeezy, and Polar may be worth modeling when global sales, VAT or sales tax handling, buyer support, and subscription operations are more painful than the headline fee difference.
| Question | Why it matters | What to compare |
|---|---|---|
| Are customers concentrated in one country? | One main market is easier to manage than many small tax jurisdictions. | Stripe plus your own tax process vs an MoR that handles more of the back office. |
| Is average order value low? | Fixed fees and failed payments hurt more when the subscription price is small. | Monthly billing, annual billing, and a higher minimum plan price. |
| Do you need full checkout control? | Direct processing can give more product and billing flexibility. | Control and custom logic against tax, invoice, and support workload. |
International card share is easier to judge with a few concrete SaaS patterns. Open the closest preset, then change the revenue, order count, and international-card percentage to match your actual checkout mix.
| Scenario | Open calculator | What to watch |
|---|---|---|
| Global early-stage SaaS | 60% international cards | Whether the blended Stripe fee plus tax workflow still beats a merchant of record. |
| Domestic-first SaaS | 15% international cards | Whether direct processing is still the simpler default while global volume is low. |
| Low-ticket global SaaS | Low AOV, global buyers | Fixed fees, international cards, refunds, and whether annual billing matters more than provider choice. |
| Annual B2B SaaS | Higher AOV, fewer orders | Whether larger order value makes international-card fees less decisive than tax and invoice workflow. |
Last checked: June 19, 2026. Stripe pricing is country-specific, and the pricing page can redirect to the relevant local page. Verify these fee lines for the country where your Stripe account is registered.
| Fee line | What to verify |
|---|---|
| Domestic card rate | The local card rate is the baseline before judging whether international cards materially change margin. |
| International card rate | Stripe separates domestic and international cards on country pricing pages, so use the correct local page. |
| Currency conversion | Check whether customer currency, settlement currency, or adaptive pricing adds another conversion fee. |
| Disputes and refunds | Chargeback/dispute fees and refund handling can matter when global buyers have higher support friction. |
| Stripe Tax, Billing, invoices | International cards do not include tax registration, filing, subscription billing, or invoice workflow by themselves. |
Stripe processing and Stripe Tax are different cost lines. A direct Stripe setup may still need tax registration, threshold monitoring, filing, invoicing, and remittance work depending on where customers buy. Keep those work streams visible so the comparison does not understate the real cost of direct processing.
Early planning can use estimated international card share, but the better model comes from real checkout exports. Once you have sales, compare domestic cards, international cards, refunds, failed payments, disputes, and plan type by month instead of relying on one launch-day assumption.
Start with 60% international cards, then adjust the calculator to your actual customer mix.
Open a Stripe international card scenarioUse product revenue before provider fees so the comparison focuses on the cost of processing, fixed fees, refunds, and disputes.
No. It is only one variable. Tax handling, checkout conversion, failed payments, support workload, and migration cost can matter as much as the fee math.
No. Provider pricing and custom terms can change. Use this calculator for planning, then confirm current pricing directly with each provider.
No. Stripe Tax can help with tax calculation workflows, but a merchant of record can take on broader seller, tax, invoice, refund, and buyer-support responsibilities depending on the provider.
