E-commerce Profit Calculator

The E-commerce Profit Calculator substitutes your inputs (Revenue, COGS, Shipping, Ad spend) into the standard expression: Profit = Revenue − COGS − Shipping − Ad spend; Profit margin = (Revenue − COGS − Shipping − Ad spend) ÷ Revenue × 100. Every variable is read straight from the fields on this page, and the result is computed the moment you enter the values.

1. 1

   Step 1

   Type revenue, costs, and the related indicators.

2. 2

   Step 2

   After entering the values, click "Calculate" to view the output.

3. 3

   Step 3

   Use the result while keeping the context and units in mind.

4. 4

   Step 4

   Review the breakdown: the result repeats the page's own expression (Profit = Revenue − COGS − Shipping − Ad spend; Profit margin = (Revenue − COGS − Shipping − Ad spend) ÷ Revenue × 100) with your values substituted, so each variable stays traceable.

   Step 5

   Compare scenarios by varying a single value per run in the e-commerce profit calculator — that isolates which of the formula's inputs actually drives the result.

• 1

  The E-commerce Profit Calculator needs every variable in consistent units — Revenue, COGS, Shipping — before the standard formula returns a valid result, so check each field's unit before entering values copied from elsewhere.

• 2

  Treat the E-commerce Profit output as a computed reference, not a guarantee: where money, health, or compliance is involved, have a professional confirm the inputs and the interpretation before you act on the number.

• 3

  Round only at the end: E-commerce Profit carries full precision internally, so rounding intermediate values by hand can shift the final answer more than the accuracy of the formula itself ever would.

• Percentage conventions differ by field: some E-commerce Profit inputs expect cogs as a whole number (5 for 5%), others as a decimal (0.05). The two forms are off by ×100 — match the field's label or example.

• Zero and negatives can sit outside the formula's domain: zero cogs may make the E-commerce Profit undefined, and a negative revenue still returns a number. Check each input is inside the range the quantity allows.
