Gross Margin Calculator

The Gross Margin Calculator substitutes your inputs (Revenue, COGS) into the standard expression: Gross margin = (Revenue − COGS) ÷ Revenue × 100; Gross profit = Revenue − COGS. 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

   Save or share the result as needed.

4. 4

   Step 4

   The breakdown lists your inputs — Revenue, COGS next to the value computed by Gross margin = (Revenue − COGS) ÷ Revenue × 100; Gross profit = Revenue − COGS; read it before relying on the number.

5. 5

   Step 5

   Adjust one input at a time and compare scenarios: change Revenue and re-run to see which variable moves the gross margin result most.

• 1

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

• 2

  Enter values in the units the Gross Margin fields expect — Revenue, COGS and the rest; mismatched units are the most common way a correct formula yields a wrong number no calculator can detect.

• 3

  For repeated what-if work on Gross Margin, change one input at a time and note the effect; that isolates which variable actually drives the result instead of moving several values at once and losing the attribution.

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

• Revenue and COGS must be entered in one consistent unit system: months against years skews the Gross Margin result silently. Convert every input to the unit named on its field first.
