Profit Margin Calculator: Gross Profit & Markup
Gross margin measures the share of revenue remaining after direct costs. It helps compare the economics of products, services, or jobs, provided revenue and costs cover the same activity and period.
THE METHOD
The formula
Use the following method with your own business figures.
Revenue must be greater than zero for a meaningful margin percentage. This tool measures gross margin when you enter direct costs only.
PUT IT TO WORK
A worked example
These figures illustrate the calculation, not a recommended business target.
- $12,500 revenue − $7,250 direct costs = $5,250 gross profit.
- $5,250 ÷ $12,500 × 100 = 42% gross margin.
- $5,250 ÷ $7,250 × 100 ≈ 72.41% markup.
The business keeps 42 cents per revenue dollar before overhead and other expenses.
USE THE RESULT
How to interpret the number
Put the result in context
Compare like-for-like jobs or periods. A higher gross margin leaves more room to cover overhead, but does not establish whether the whole business is profitable.
CHECK YOUR ASSUMPTIONS
Common mistakes
Check the inputs and assumptions
Margin divides profit by revenue; markup divides profit by cost. Substituting one percentage for the other can lead to an underpriced quote.
Questions business owners ask
Use these answers to refine the assumptions behind the calculator—not as a substitute for advice specific to your business.
Is gross margin the same as net margin?
No. Gross margin subtracts direct costs. Net margin reflects all relevant expenses. The scope of the costs entered determines what the result describes.
