Stripe, Adyen or Worldpay for a Growing UK Retailer
Stripe charges a flat 1.5% + 20p online and 1.4% + 10p in person, Worldpay charges 1.3% + 20p online for a business with a live ecommerce site, and Adyen itemises the interchange rate, a 0.60% markup and a $0.13 fee separately rather than publishing one blended percentage. At a modelled £15,000 of monthly online sales on debit cards, Stripe costs about 2.30% effective, Worldpay about 2.10%, and Adyen's published formula about 1.20%, before its unpublished minimum invoice is confirmed by quote.
