eCommerce Pricing Calculator

Compare what leading US eCommerce platforms would cost your online store each month, including card processing.

- Cheapest option at your volume
$0 Estimated monthly cost
Provider Monthly cost Effective rate 12-month total

Monthly cost combines the platform subscription with online card processing at each platform's standard US rate using its native payment option, so no extra platform transaction fee applies. The 12-month total is simply twelve times the monthly cost; themes, apps, and premium plugins are extra on every platform. Rates are published US pricing as of mid-2026.

How the eCommerce Pricing Calculator works

An online store has two unavoidable recurring costs: the platform subscription and payment processing. Processing is the one that scales with your success. Most US platforms process online cards at around 2.9% + $0.30 per order through their native payment option, but the differences compound: BigCommerce's 2.59% + $0.49 favors larger orders, Square Online's free plan trades a $0 subscription for a higher 3.3% + $0.30 rate, and Shopify discounts its rate as you move up plans but adds a 0.6% to 2% penalty if you use a third-party gateway instead of Shopify Payments. The fixed per-order fee also means your average order value matters: $0.30 is 1% of a $30 order but only 0.3% of a $100 order.

This calculator estimates your monthly order count from your sales volume and average order value, then costs out each platform using its subscription price and its standard US online processing rate with the native payment option, ranking the results by total monthly cost. The effective rate column shows the true percentage of revenue each platform takes once subscription and processing are combined, which is the single best number for comparing options as your store grows.

Assumptions used in this calculator

  • Platform prices are published US rates as of mid-2026: Shopify Basic $39 and Grow $105 per month, BigCommerce Standard $39, Wix Business $36, Squarespace Commerce Basic around $28 billed annually, Square Online free, and WooCommerce modeled at roughly $20 per month for quality managed hosting.
  • Processing uses each platform's native option (Shopify Payments, Wix Payments, WooPayments, Square, PayPal powered by Braintree for BigCommerce), which avoids additional platform transaction fees.
  • Shopify adds 0.6% to 2% per sale on top of gateway fees if you do not use Shopify Payments; Squarespace's cheaper Business plan carries a 3% platform transaction fee and is not modeled here.
  • Themes, apps, plugins, premium email, and shipping tools are excluded; a typical WooCommerce build often lands at $60 to $80 per month all-in once hosting, theme, and plugins are counted.
  • International cards, currency conversion, and in-person POS rates differ from the online rates shown.
