Frequently asked questions
- Is the Profit Margin Calculator free?
- Yes, it is completely free to use with no sign-up, account, or limits.
- Is my data uploaded anywhere?
- No. All calculations run entirely in your browser, and the numbers you enter never leave your device.
- What is the difference between margin and markup?
- Margin is profit as a percentage of the selling price (revenue), while markup is profit as a percentage of the cost. The same profit produces a lower margin than markup.
- How is profit margin calculated?
- Profit is revenue minus cost, and margin is that profit divided by revenue, multiplied by 100 to get a percentage.
- Why does margin or markup show a dash?
- To avoid dividing by zero, margin requires a revenue above zero and markup requires a cost above zero. If either is zero, that percentage shows a dash.
- Can I use it for any currency?
- Yes. The math works with any currency, and the percentages are currency-independent, so just enter your cost and price in whatever currency you use.
