How to use this ecommerce profit calculator

Enter values from the same reporting period and use consistent definitions. Then select Calculate. The tool performs the calculation locally in your browser and shows the result immediately.

Formula

Estimated Profit = Revenue − COGS − Shipping − Payment Fees − Ad Spend − Other Included Costs

Example

$10,000 revenue minus $3,500 COGS, $900 shipping, $320 payment fees, $2,200 ads and $300 other costs leaves $2,780, or a 27.8% margin before costs not entered.

What this metric tells you

Revenue alone can make a store look healthier than it is. This calculator forces the main variable cost buckets into one view so you can estimate how much is left after customer acquisition and fulfillment.

How to interpret the result

  • Keep cost categories mutually exclusive so the same expense is not counted twice.
  • This is an operating estimate, not a replacement for accounting statements.
  • Add fixed overhead separately if you need full net profit after salaries, software, rent and tax.
Important: Calculators provide estimates based on the inputs you supply. They do not replace platform reporting, accounting records, tax advice or professional financial analysis.

Frequently asked questions

Does this calculate true net profit?

Only to the extent that you enter all relevant costs. It is designed as an ecommerce operating estimate, not a formal income statement.

Should refunds be included?

Yes, if they materially affect revenue or costs. Use net revenue or include refund-related losses in other costs, but avoid double counting.

Can I use this for one product?

Yes. Use unit-level revenue and costs to estimate per-order contribution.
