Ecommerce Transaction Fee Calculator

See how much ecommerce platform transaction fees cost you per year — and how much you'd keep on a 0% platform. Compare Shopify, BigCommerce, WooCommerce and more.

Platform fee only — the % your platform charges on top of payment processing. Everyone still pays their processor (e.g. ~2.9% + 30¢); that part isn't included here.

Platform transaction fees / year

On a 0% platform (like ShopsWired)

You'd keep more per year.

This platform already charges 0% platform fees — nice. The difference then comes down to hosting, customization, and what else the platform charges for.

What are ecommerce transaction fees?

A platform transaction fee is an extra percentage your ecommerce platform charges on every sale — separate from, and on top of, what your payment processor (Stripe, PayPal, etc.) charges to move the money. It's easy to overlook because it's a small percentage, but on real sales volume it compounds into thousands of dollars a year that never touch your bank account.

This calculator isolates that platform fee so you can see its true annual cost, and compares it against a platform that charges 0%. Payment-processing fees (typically around 2.9% + 30¢ per transaction) are not included, because you pay those on essentially any platform.

How platform fees compare

  • Shopify charges a transaction fee only if you use a third-party payment gateway instead of Shopify Payments — 2.0% on Basic, 1.0% on Shopify, and 0.6% on Advanced. Using Shopify Payments waives that platform fee, but ties you to Shopify's own processor and its standard processing rates.
  • BigCommerce does not charge a platform transaction fee on any plan, on any gateway.
  • WooCommerce is self-hosted and charges no platform transaction fee — you pay your processor and your own hosting/maintenance instead.
  • ShopsWired charges 0% platform transaction fees on every plan and lets you use your own processor — you pay only your processor's standard rate.

Fee figures reflect publicly published rates at the time of writing and can change — always confirm current pricing on each provider's site.

How to use this calculator

Enter your monthly online sales and pick your platform and plan (or enter a custom rate). The calculator shows what that platform's transaction fee costs you per year, and how much you'd keep on a 0%-platform-fee provider. If your platform is already at 0%, the tool says so — the honest answer matters more than a scary number.
