How the Magento Open Source vs Shopify calculator works, and how the two compare
Magento Open Source is the free, self-hosted edition of Adobe's enterprise commerce platform, aimed at merchants with developers. Magento Open Source is free to license; realistic costs are hosting from around $50 per month plus developer time, with processing via Stripe, PayPal, or Braintree at standard rates around 2.9% + $0.30. Shopify is the leading dedicated eCommerce platform in the US, which also sells in person through Shopify POS. Shopify Basic is $39 per month at 2.9% + $0.30 online with Shopify Payments (Grow $105 at 2.7% + $0.30); in-person processing is 2.6% + $0.10 with POS Lite included in every plan, and POS Pro adds $89 per month per location.
How they are similar: Where they overlap: both Magento Open Source and Shopify cover selling online, which is what this calculator compares. In both cases the bill is driven by a percentage of each sale plus any fixed per-transaction fee, which is why your average transaction size changes the effective rate as much as the headline percentage does.
How they differ: Only Shopify offers in-person card readers and a full POS system, so that side of the business is not part of this comparison. Magento Open Source operates as free open-source software where you pay for hosting and processing rather than the platform itself, while Shopify operates as a subscription platform where you pay a monthly plan plus payment processing. Magento offers enterprise-grade catalog and customization power for free, but it is developer-heavy: maintained builds commonly cost tens of thousands per year in hosting and DevOps at scale. Shopify's strength is depth and ecosystem: the largest app store in commerce and true omnichannel selling, but third-party gateways trigger an extra 0.6% to 2% fee and app costs creep up at scale.
