About This Tool
NinjaFunction's Profit Margin and Markup Calculator turns a price and a cost into the profit, the margin and the markup, finds the selling price needed for a target margin or markup, and works out gross, operating and net margin from a simple income statement. It explains why margin and markup are not the same. Everything runs in your browser.
Why a Falling Margin Is an Early Warning
Sales can grow while profit shrinks. If your costs rise by 5% and you keep prices the same, a 20% margin falls to roughly 16%, and the owner often notices only when cash runs short. Calculating the margin every month, for each product line, shows which items earn their place on the shelf and which only look busy.
Gross margin is the first number to watch, because it shows whether the product itself pays. If it is healthy but net margin is poor, the problem is in running costs. If gross margin is thin, the problem is in price or purchasing.
Frequently Asked Questions
What is the difference between margin and markup?
Margin is profit as a share of the selling price. Markup is profit as a share of the cost. For a product that costs 100 and sells for 150, the profit is 50, the margin is 33.3% and the markup is 50%.
Why do people mix them up?
Because both come from the same two numbers. The danger is pricing: a 50% markup is not a 50% margin. To get a 50% margin on a cost of 100 you must sell at 200, which is a 100% markup.
How do I find the price for a target margin?
Divide the cost by (1 โ margin). For a cost of 100 and a 25% margin, the price is 100 รท 0.75 = 133.33. The Find the price tab does this for you.
What is gross, operating and net margin?
Gross margin takes only the cost of goods off revenue. Operating margin also subtracts running costs such as rent and salaries. Net margin subtracts everything, including interest and tax.
What is a good profit margin?
It varies a lot by trade. Groceries often have net margins of 1% to 3%, restaurants 3% to 9%, software and consulting much higher. Compare with your own industry.
Should the cost include my own time?
If you count it as a real cost, yes. Many small businesses look profitable only because the owner is not paid. Include a fair wage to see the true margin.
