About Margin Calculator
The Margin Calculator helps businesses understand their profitability metrics from multiple directions. Enter cost and revenue to instantly calculate gross margin percentage, markup percentage, and gross profit in currency terms.
The calculator also works in reverse: enter a cost and target margin percentage to find the selling price you need to hit that margin, or enter revenue and target margin to determine the maximum allowable cost. This flexibility makes it useful for pricing strategy as well as financial reporting.
All calculations run locally in your browser with no data sent to any server, so sensitive pricing and cost information stays private. The tool is designed for entrepreneurs, product managers, and financial analysts who need fast and accurate profitability figures.

Troubleshooting
Confusing margin with markup
Solution
Margin uses revenue as the denominator (Profit / Revenue). Markup uses cost as the denominator (Profit / Cost). A 33.33% margin equals a 50% markup on the same transaction.
Entering cost greater than revenue
Solution
If cost exceeds revenue, the margin is negative, indicating a loss. The calculator will show a negative margin, which is a valid and informative result.
Entering a target margin of 100% or above
Solution
A 100% margin is impossible because it would require zero cost. Gross margin must always be below 100%. If you need a specific profit multiple, use markup mode instead.
Frequently Asked Questions
What is the difference between margin and markup?
Margin = (Revenue - Cost) / Revenue x 100. Markup = (Revenue - Cost) / Cost x 100. For the same transaction, markup is always a higher percentage than margin. A 50% markup on a 40 item gives a 33.33% margin.
How do I find the selling price for a target margin?
Use the reverse mode: enter your cost and target margin percentage. The formula is Selling Price = Cost / (1 - margin/100). For example, a 40% margin on a 60 cost gives a selling price of 100.
What is gross margin vs net margin?
Gross margin only deducts the cost of goods sold (COGS) from revenue. Net margin deducts all expenses including operating costs, taxes, and interest. This calculator computes gross margin.
Can I calculate markup instead of margin?
Yes. The calculator shows markup percentage alongside margin whenever you enter cost and revenue. Markup = (Profit / Cost) x 100.
Why is margin always lower than markup for the same deal?
Margin uses the larger number (revenue) as the denominator, while markup uses the smaller number (cost). Dividing the same profit by a larger number always gives a lower percentage.
What does a negative margin mean?
A negative margin means the revenue is less than the cost — you are selling at a loss. The calculator will show the negative figure to make the loss visible.
Can I use this for service businesses?
Yes. Replace "cost" with your total labor and material costs for a service engagement, and "revenue" with the amount you charge the client. The margin calculation is identical.
Is my data private?
Yes. All calculations run entirely in your browser. No financial data is transmitted to or stored on any server.
