You run a SaaS business on Stripe. You offer coupons to boost signups. But here's the catch: those discounts hit your revenue hard because Stripe coupon fees charge the full processing rate on the original amount.
SaaS owners often overlook this. Your customer pays less, yet you cover Stripe fees as if they paid full price. In 2026, with subscriptions steady at 2.9% + $0.30 per domestic card charge, these costs add up fast.
This guide breaks down Stripe processing fees SaaS teams face. You'll see the Stripe fee breakdown, coupon impacts, and ways to cut expenses.
Stripe's Standard Fee Structure in 2026
Stripe keeps its core rates simple for US domestic cards. You pay 2.9% plus 30 cents on every successful charge. This applies to SaaS subscriptions too.
International cards add 1.5% more. Currency conversion tacks on another 1%. Add-ons like Stripe Tax cost 0.5%. Your effective rate often climbs to 4-5% or higher.
Here's a quick view of common SaaS payment processing costs:
| Fee Type | Rate | Example on $100 Sale |
|---|---|---|
| Domestic Card | 2.9% + $0.30 | $3.20 |
| International Card | +1.5% | $4.70 |
| Currency Conversion | +1% | $4.20 (base +1%) |
| Stripe Tax | 0.5% | $0.50 extra |
This table shows why blended rates surprise many founders. Small transactions hurt most because of the fixed 30 cents.
Fees stay steady in April 2026. No major hikes reported. However, volume matters. Enterprise plans negotiate lower rates.
How Coupons and Discounts Work on Stripe
Stripe makes coupons easy. You set percentage offs, fixed amounts, or free trials. Customers enter promo codes like "SAVE50" at checkout.
For SaaS, coupons apply to subscriptions. A 50% off first month reduces what the customer pays. Prorations handle mid-cycle changes.
The problem? Stripe bases Stripe fees on the original subscription amount. You eat the discount plus full processing costs.
Say your monthly plan costs $100. Customer uses 50% coupon, pays $50. Stripe still charges you 2.9% + $0.30 on $100. That's $3.20 gone, or 6.4% of what you actually received.
Promotion codes link to coupons for sharing. Duration limits help, like three months max. Bundles or spending caps work for usage-based billing.
This setup boosts acquisition. But without offsets, stripe coupon fees erode margins, especially at scale.
Extra Costs That Stack Up for SaaS
Subscriptions bring unique fees. Failed payments cost retry attempts. Disputes hit $15 each. Cross-border sales add FX fees.
ACH payments drop to 0.8% capped at $5. But cards dominate SaaS, so most pay the full 2.9% + $0.30.
In 2026, options like Klarna charge 5.99% + $0.30. Instant bank payouts are 2.6% + $0.30, a slight win.
