Gross Margin Calculator

Measure revenue left after the direct costs of delivering the product.

6 min guideTransparent methodologyUSDGo to calculator ↓
01 / UNDERSTAND THE CONCEPT

Growth is more valuable when delivery leaves a contribution.

Gross profit is revenue less the cost of goods or services sold. Gross margin expresses that profit as a share of revenue. SaaS delivery costs can include hosting, third-party usage and service staff, depending on the accounting policy.

Consistency matters more than a flattering classification. Moving delivery costs into operating expense improves the displayed gross margin without changing total profit. Compare like-for-like policies and business models.

02 / THE MATHEMATICS

The formula, made clear.

Gross profit = revenue − COGS; gross margin = gross profit ÷ revenue
COGS
Direct costs matched to the revenue in the same period.
Gross margin
A percentage of revenue, not a markup on cost.
03 / A WORKED EXAMPLE

Put the numbers in context.

$500,000.00 revenue less $150,000.00 delivery costs produces $350,000.00 gross profit and 70% gross margin.

MODEL BOUNDARIES

What this calculation assumes

Consistent revenue and cost recognition. Costs may exceed revenue, producing a negative margin. With zero revenue the percentage is undefined while the absolute loss remains measurable.

FROM UNDERSTANDING TO ACTION

What to consider next.

Use a consistent gross margin in LTV and CAC payback. Separate variable costs from fixed delivery costs when calculating contribution.
