Working note
Make the estimate useful.
Margin describes how much of each revenue unit remains after selected costs. Gross margin stops after cost of goods sold; net margin also subtracts operating expenses. Use the same cost definition whenever you compare periods or products.
Questions from the desk
Profit Margin Calculator FAQ
What is the difference between margin and markup?
Margin divides profit by revenue. Markup divides gross profit by cost, so the two percentages are not interchangeable.
Can profit margin be negative?
Yes. A negative result means the selected costs exceed revenue for the modeled period or product.
Should owner pay be an expense?
That depends on the business structure and the purpose of the analysis. For operating decisions, include a fair labor cost somewhere in the model.
