A furniture client was on the Basic plan doing roughly $180,000 a month, proud of the low $25 subscription. They were paying the 2.9% Basic card rate on every order. Moving to Advanced cut the rate to 2.5%, which on their volume saved about $720 a month in processing against a $374 subscription increase. They were leaving roughly $4,100 a year on the table to save $374.
This calculator runs that math for any store. Enter your monthly revenue, order count, and the features you need, and it compares the total cost (subscription plus processing) on Basic, Shopify, Advanced, and Plus, then shows where upgrading pays for itself. If the math points to Plus, the nine checkout rules for Shopify Plus in 2026 cover what actually changes when you move up.
