Universal Payment Processor Fee Comparator

Payment processor fee comparison is the process of evaluating different payment processing providers side by side to determine which offers the lowest total cost for your specific transaction profile. Each processor has a unique fee structure combining a percentage rate (typically 2.59% to 2.99%), a fixed per-transaction fee ($0.10 to $0.49), and sometimes a monthly fee. Our payment processor fee comparator calculates the true cost for each processor based on your transaction amount, monthly volume, and average ticket size - giving you an apples-to-apples comparison that accounts for all fee components and card type surcharges.

1. 1. Enter Your Transaction Profile: Start by entering your typical transaction amount, your total monthly processing volume, and your average ticket size (average value per transaction). The payment processor fee comparator also asks for your card type - Visa/Mastercard or American Express - since Amex typically has slightly higher processing rates across all processors.
2. 2. Processor Fee Calculation: For each of the 7 supported processors (Stripe, PayPal, Square, Adyen, Braintree, Shopify Payments, WooCommerce Payments), the comparator calculates the per-transaction fee, total monthly cost (accounting for your monthly volume and number of transactions), annual cost projection, and effective fee rate. The calculator accounts for each processor's unique rate, fixed fee, and any applicable surcharges.
3. 3. Review Ranked Results: The comparator displays processors ranked from cheapest to most expensive based on your monthly processing costs. You get a visual bar chart showing relative costs, individual rank cards with key metrics for each processor, a full comparison table with all fee components, and a clear savings analysis showing how much you could save by switching from the most expensive to the cheapest processor for your volume.

• Fee Per Transaction: The total fee charged by the processor for a single transaction at your entered amount. This includes both the percentage rate and the fixed per-transaction fee. For example, a $100 transaction with Stripe's 2.9% + $0.30 would show a $3.20 transaction fee.
• Monthly Processing Cost: The total monthly cost estimated by applying the processor's fee structure to your monthly volume and estimated number of transactions (monthly volume ÷ average ticket size). This gives you the most relevant cost figure for comparison.
• Annual Cost Projection: Your monthly cost multiplied by 12 for a forward-looking annual cost estimate. This helps evaluate the long-term financial impact of choosing one processor over another.
• Effective Rate: The true percentage rate you are paying when the fixed fee is factored in. This is calculated as (total monthly fees ÷ monthly volume) × 100. For low-value transactions, the effective rate can be significantly higher than the nominal percentage rate due to the fixed fee component.
• Potential Savings: The difference between your current (or most expensive) processor's monthly cost and the cheapest option. This is displayed both monthly and annually to show the real financial impact of switching.

Each payment processor has a different fee structure that makes direct comparison essential. Stripe charges 2.9% + $0.30 per transaction with no monthly fee, making it ideal for low-to-medium volume businesses. PayPal charges 2.99% + $0.49 - slightly higher than most competitors but offers brand recognition and buyer trust. Square offers competitive in-person rates at 2.6% + $0.10 but charges 2.9% + $0.30 for online transactions. Adyen has custom pricing for high-volume merchants. Braintree (a PayPal service) offers 2.59% + $0.49 with the first $50,000 processed free. Shopify Payments has the same base rate as Stripe (2.9% + $0.30) but eliminates Shopify's additional transaction fees. WooCommerce Payments also matches Stripe's pricing since it is built on Stripe's infrastructure.
