Shopify Transaction Cost Calculator

Shopify Payments charges a percentage of the order value plus a flat $0.30 per transaction, and that flat portion matters proportionally more on a small order than a large one — a $0.30 flat fee is 3% of a $10 order but only 0.3% of a $100 order. So while the dollar amount of your Per-Order Fee grows with order value, the Fee as % of Order actually shrinks as Average Order Value rises, because the fixed component gets diluted across a bigger sale.

No — Monthly Orders has no effect on Per-Order Fee or Fee as % of Order in this calculator, since both of those are computed purely from Average Order Value, the selected plan's rate, and whether Shopify Payments is used. Monthly Orders only multiplies that already-fixed per-order fee to produce Monthly Transaction Fees and, combined with the flat plan subscription, Monthly Total Cost and Annual Total Cost.

Shopify charges an additional transaction fee, on top of whatever your outside payment processor charges you separately, whenever you route payments through a gateway other than Shopify Payments — the surcharge in this calculator ranges from 0.6% on the Advanced plan up to 2% on Basic. Using Shopify Payments instead avoids that extra surcharge entirely, which is why it's usually the cheaper choice unless you have a specific reason — like an existing merchant account — to use a third-party processor.

Each higher plan tier lowers the payment-processing percentage rate — from 2.9% on Basic down to 2.7% on Shopify and 2.5% on Advanced — so the upgrade pays for itself once your transaction-fee savings from that lower rate exceed the jump in monthly subscription cost. Compare Monthly Total Cost across tiers at your actual Average Order Value and Monthly Orders rather than relying on the sticker price of the plan alone, since a high-volume store can save far more from the rate cut than it pays in extra subscription fees.
