Benchmarks for payment processing fees across major methods — credit cards, digital wallets, BNPL, and alternative payments.
Payment processing fees consume 2.5-4% of ecommerce revenue on average. For a $20M merchant, that is $500K-$800K annually — a cost line item that most merchants accept as fixed. But payment method mix optimization can save 0.3-0.8% of revenue. Additionally, BNPL fees (3.5-6%) are often poorly understood — the AOV lift must exceed the fee premium to be profitable.
| Tier / Category | Range | Notes |
|---|---|---|
| Credit/Debit Cards (Shopify Payments) | 2.15-2.9% + $0.30 | Shopify Plus gets lowest tier (2.15%); standard plans pay 2.4-2.9% |
| PayPal | 2.59-3.49% + $0.49 | Higher fees but trusted brand increases conversion for some demographics |
| Apple Pay / Google Pay | 2.15-2.9% + $0.30 | Same underlying card rates but higher conversion due to frictionless checkout |
| Buy Now Pay Later (Klarna, Affirm) | 3.5-6.0% + $0.30 | Highest fees; increases AOV by 30-50% but margin impact must be modeled |
| ACH / Bank Transfer | 0.5-1.0% | Lowest cost but limited to B2B/wholesale; poor consumer UX |

Calculator
Shopify Plus merchants pay three distinct fees that most operators never combine into a single number: the platform fee (starting at 2,000 per month and scaling with revenue on large accounts), transaction fees of up to 0.15 percent for merchants not using Shopify Payments, and payment processing fees that start at 2.9 percent plus 30 cents per transaction on Shopify Payments.
Calculator
Most ecommerce founders know their revenue number by heart — but far fewer can tell you their true profit margin without pulling up a spreadsheet.
Shopify Payments offers the lowest rates for Shopify Plus merchants at 2.15% + $0.30 per transaction. Using a third-party gateway adds an additional 0.15-0.20% surcharge on top of the gateway's own fees. For most Shopify Plus merchants, Shopify Payments is the cost-optimal choice.
BNPL is worth it only if the AOV increase exceeds the fee premium on a margin-adjusted basis. BNPL fees run 3.5-6%, about 1.5-3% higher than card processing. If BNPL increases AOV by 30% and your contribution margin on the incremental revenue exceeds the fee premium, it's profitable. Model it per product category.
Use Shopify Payments (lowest Shopify Plus rates), encourage express payment methods (same rates, higher conversion), limit PayPal exposure through checkout UX, and reduce chargebacks through fraud screening. Combined, these strategies can save 0.3-0.8% of revenue.
