Shopify Profit Calculator

How it is calculated

The tool works out the per-unit result of one sale in three steps. Payment fee: fee = price × rate ÷ 100 + fixed fee. Profit: profit = price − product cost − fee. Margin: margin % = profit ÷ price × 100.

Rate is the percentage your payment processor takes and fixed fee is the flat amount added to each transaction; you enter both yourself, so the tool uses whatever rates apply to your plan or gateway (the form starts with 2.9% and 0.30). Amounts are in dollars. The price must be above zero and the other inputs cannot be negative. Only the payment fee is deducted: the monthly subscription, shipping, taxes, refunds, discounts and ad spend are not included, so subtract them separately.

Common mistakes

• Forgetting the fixed fee. On cheap items it matters: at a $12 price and $9 cost, the same fees take 0.65 and cut the margin to 19.60%.
• Entering the payment rate as a decimal (0.029). The field is in percent, so type 2.9.
• Treating the result as the profit of the whole business. It excludes subscription, shipping, returns, taxes and advertising.
• Using the price before discounts when customers pay a discounted price; the fee is charged on what they actually pay.
• Using the rate from the wrong plan or a third-party gateway. The fees differ, so enter the ones that match how this order was paid.
