Frequently asked questions

Short, practical answers for this calculation.

What is a good profit margin?

It depends on industry, costs, and business model. This calculator only performs the math.

Why is margin lower than markup?

They use different denominators. Margin divides by selling price; markup divides by cost.

Can margin exceed 100%?

Gross margin cannot exceed 100% if cost is non-negative, because profit cannot exceed revenue in that simple setup.

Should tax be included?

Usually margin is calculated before sales tax or VAT, but accounting practices vary.
