Understand your ecommerce store profit

Revenue is not the same as profit. A store can generate strong sales and still lose money when product costs, fulfillment, payment processing, advertising, software, and payroll are added together.

This free calculator gives merchants a practical monthly estimate. It separates gross profit from operating expenses, shows your estimated net margin, and calculates approximately how many orders you need to break even.

How to use the store profit calculator

  1. Enter your sales volume. Add your average monthly orders and average order value.
  2. Add variable costs. Estimate product costs, shipping, and payment processing as accurately as possible.
  3. Add fixed expenses. Include marketing, apps, payroll, contractors, rent, insurance, and other monthly costs.
  4. Review the result. Use net profit, margin, and break-even orders to identify where your store can improve.

What is a good ecommerce profit margin?

There is no single margin that works for every merchant. Product category, fulfillment model, customer acquisition cost, returns, and business stage all affect profitability. Use the result as a baseline, then compare it with your own targets and historical performance.

Merchant tip: Run the calculator three times: with your current numbers, with a lower advertising cost, and with a higher average order value. The comparison can reveal which improvement has the greatest financial impact.

Store profit calculator FAQ

What is the difference between revenue and net profit?

Revenue is the total amount collected from customers. Net profit is what remains after product costs, shipping, payment processing, marketing, software, payroll, and other operating expenses are deducted.

Should shipping be included in cost of goods sold?

Use the method that matches your bookkeeping, but do not count the same shipping cost twice. This calculator treats shipping as a separate per-order cost so merchants can see its impact clearly.

How is the break-even order count calculated?

The calculator divides estimated monthly fixed expenses by contribution profit per order. Contribution profit per order is average order value minus product cost, shipping, and payment processing.

Does this calculator include taxes?

No. Tax treatment varies by business structure, location, deductions, and accounting method. Treat the result as an operating profit estimate before income taxes.
