Shopify Plus merchants pay three distinct fees that most operators never combine into a single number: the platform fee (starting at 2,000 per month and scaling with revenue on large accounts), transaction fees of up to 0.15 percent for merchants not using Shopify Payments, and payment processing fees that start at 2.9 percent plus 30 cents per transaction on Shopify Payments. This calculator adds all three into your true effective fee rate. Enter your monthly revenue, transaction fee percentage, payment processing percentage, payment processing flat fee, platform fee, and orders per month — and see the total dollars Shopify collects from you each month and the effective fee as a percentage of revenue. Built for brands comparing Shopify Plus to BigCommerce Enterprise, Salesforce Commerce Cloud, or a custom stack.

Transaction fees are calculated as Monthly Revenue multiplied by the Transaction Fee Percentage divided by 100 — this fee applies only when a merchant uses a third-party payment gateway instead of Shopify Payments. Payment processing fees are calculated as Monthly Revenue multiplied by Payment Processing Percentage divided by 100, plus Orders per Month multiplied by the Flat Fee per Order. On Shopify Plus, the standard rate is 2.9 percent plus 30 cents domestic, but negotiated rates for high-volume merchants can drop to 2.5 percent or lower. Platform fees are the flat monthly charge, starting at 2,000 for standard Shopify Plus and rising to a revenue-based calculation above a specified GMV threshold. Total fees is the sum of all three. Effective fee rate is Total Fees divided by Monthly Revenue, expressed as a percentage. This model excludes international card surcharges, American Express premiums, chargeback fees, and Shopify apps with revenue-share billing, all of which add incremental cost — the true all-in Shopify cost for most mid-market brands is 50 to 100 basis points higher than what this calculator shows.
For a typical mid-market Shopify Plus brand at 1.5 million monthly revenue using Shopify Payments, the blended effective fee rate lands around 3.0 to 3.2 percent of revenue. Below 500K in monthly revenue, the 2,000 platform fee alone adds 40 basis points on top of payment processing, pushing the effective rate above 3.3 percent. Above 5 million in monthly revenue, the platform fee gets diluted and effective rates drop toward 2.9 percent — but only if you are on Shopify Payments. Brands using external gateways pay the 0.15 percent transaction fee on top, which can be 2,250 per month extra at 1.5 million revenue. The practical implication: at mid-market scale, Shopify fees alone consume around 3 percent of revenue, which on a 55 percent gross margin business is roughly 5 to 6 percent of gross profit. That is money that needs to be planned against, not discovered at month-end.
Shopify fees are fixed and predictable — they are not where your margin problem lives. The margin problem lives in the sub-fee layer: discount stacks, freight zone misses, and COGS drift that quietly ship orders below your profit floor. Agentis does not touch your fee structure; it enforces the margin that has to clear above those fees. By blocking sub-floor orders at checkout in real time, it ensures the fees you pay are charged against profitable revenue, not against orders that were already underwater before the fees hit. The calculator shows you the fixed cost of being on Shopify Plus; Agentis protects the variable margin that sits on top.
The platform fee starts at 2,000 per month for standard accounts and transitions to a revenue-based rate above a specified GMV threshold. Payment processing is 2.9 percent plus 30 cents on Shopify Payments (negotiable at scale), plus a 0.15 percent transaction fee if you use an outside gateway.
Yes. Brands above 5 to 10 million monthly revenue routinely negotiate payment processing down toward 2.5 percent and secure platform fee concessions. The leverage comes from volume commitments and multi-year contracts.
Shopify Payments avoids the 0.15 percent transaction fee and simplifies reconciliation. Third-party gateways can offer better rates for very high-volume merchants, international optimization, or specific B2B features. For most mid-market DTC brands, Shopify Payments is the cheaper and simpler choice.
Yes. International card surcharges, American Express premiums, chargeback fees, and revenue-share pricing on premium apps all add cost. True all-in fees typically run 50 to 100 basis points above what this calculator displays.
