Checkout Payment Statistics: Methods, Declines and Abandonment

Selected article findings, not the complete article.

In Baymard's US research, 19% reported distrusting the site with their card details, 10% reported a declined credit card and 9% reported too few payment methods. Trust was 10 percentage points ahead of limited choice in the same published breakdown. The reason percentages can overlap. They are self-reports, without a denominator of payment attempts or a processor log.

In the ECB's 2024 euro-area diary, cards accounted for 48% of online payments and e-payment solutions accounted for 29%, a 19-point gap by transaction count. The ECB counts debit, credit and prepaid cards as cards. E-payment solutions include wallets, PayPal, other mobile apps and iDEAL in the Netherlands. Recurring bills and orders paid in person sit outside this online mix.

Stripe reported 7.4% higher conversion and 12% higher revenue on average when its experiment dynamically showed at least one additional relevant payment method beyond cards. Stripe measured an average across its eligible experiment. Results for a specific store depend on the shopper, method and mix of orders.

Across the euro area, 79% of respondents reported no online payment issues in ECB SPACE 2024. Entering payment information was the most commonly reported type of difficulty, cited by 7% of respondents. Respondents could name multiple difficulties. The source reports shopper experiences, without a transaction-level failure rate.
