Stripe and PayPal are the two most widely used online payment processors globally. While both handle card payments, they approach the market from different angles — Stripe as a developer-first infrastructure company, PayPal as a consumer-facing wallet and checkout system. The fee difference is small but consistent.
Standard Online Fees
Stripe charges 2.9% + $0.30 per online card transaction. PayPal charges 2.99% + $0.49 for standard Goods & Services checkout. On a $100 transaction, Stripe takes $3.20 while PayPal takes $3.48 — a difference of $0.28. That may sound small, but at 1,000 transactions/month it adds up to $280/month or $3,360/year.
Fee Comparison Across Transaction Types
The gap widens for certain payment types. Stripe's ACH Direct Debit (0.8%, capped at $5) is dramatically cheaper than PayPal's bank transfer options. For international payments, Stripe adds 1.5% for cross-border cards, while PayPal adds 1.5% for currency conversion. Both charge similarly for international transactions.
PayPal offers QR code payments at 1.90% + $0.10 for transactions over $10, which is significantly cheaper than either processor's standard online rate. For in-person businesses that can use QR codes, this is a notable PayPal advantage.
Checkout Conversion
PayPal's biggest advantage isn't its fee structure — it's checkout conversion. PayPal has over 430 million active accounts. Offering PayPal as a checkout option can increase conversion rates by 28-40% according to PayPal's own studies (and ~10-15% according to independent research). Many customers trust PayPal's buyer protection and prefer not to enter card details directly.
Stripe, on the other hand, powers invisible checkout experiences. The customer stays on your site, enters their card, and never sees the Stripe brand. This gives you more control over the user experience but lacks the trust signal that the PayPal button provides.
Developer Experience
Stripe's API is widely considered the gold standard for payment integration. Clean documentation, excellent SDKs, webhooks that actually work, and a robust test mode make development faster and more reliable. PayPal's developer experience has improved but still lags behind Stripe in documentation quality and API consistency.
For most online businesses, the optimal strategy is to use both: Stripe as the primary processor with PayPal as an alternative checkout option. This gives you the lower per-transaction cost of Stripe while capturing buyers who prefer PayPal's trusted checkout flow.
