Polar vs Paddle: plans, usage billing, and SaaS tradeoffs
Consider Polar when usage billing and product benefits are central to your developer product. Compare Paddle when its software billing workflows and service fit your business better. Both act as Merchant of Record for covered sales, so the decision depends on eligibility, billing requirements, and total cost.
What is different?
| Question | Polar | Paddle |
|---|---|---|
| Public pricing approach | Free Starter and paid plans with lower transaction rates | Pay-as-you-go rate, with custom pricing available |

| Seller onboarding | Published seller countries and Stripe Connect Express | Paddle business and product approval |
What would a $10,000 month cost?
These are the same fee rules used by the payment picker calculator. The example is 200 one-time orders at $50 each, paid with US domestic cards for a US business. No sales tax is collected. It excludes subscriptions, refunds, disputes, payouts, currency conversion, and optional services.
| Provider / plan | Fee rule | Month | Effective rate |
|---|---|---|---|
| Polar, Starter | 5% + $0.50 | $600.00 | 6% |
| Polar, Pro | $20/month, then 3.8% + $0.40 | $480.00 | 4.8% |
| Polar, Growth | $100/month, then 3.6% + $0.35 | $530.00 | 5.3% |
| Polar, Scale | $400/month, then 3.4% + $0.30 | $800.00 | 8% |
| Paddle | 5% + $0.50 | $600.00 | 6% |

Which plan belongs in the comparison?
Polar Starter and Paddle have the same headline rate in this one-time domestic-card example. Polar paid plans change the calculation: include the monthly subscription before deciding a lower percentage saves money.
The table shows all current Polar plans for the same month. It excludes international cards. If you serve buyers outside the US, model their share in the payment picker and read the fee exclusions. An older Polar organization may have Early Member terms that need a separate comparison.
What should you test for your product?
For a metered developer product, try creating a customer, recording usage, issuing a bill, and keeping the customer entitlement correct. Check each provider against that whole workflow.
For an ordinary subscription, focus on trials, upgrades, cancellation, failed renewals, and support. Having more billing features does not help if the one your business depends on behaves differently from what you need.
What could rule either one out?
Seller country and product approval come first. Then check payout timing, payout currency, dispute handling, and migration help. Neither provider taking the seller role eliminates your own product obligations or company taxes.
For an existing subscription business, ask both providers how they would move your actual customers. Use that answer beside the fee table when deciding whether switching is worthwhile.
