Profit Margin vs Markup Calculator

How this is calculated

⚠️ MARGIN AND MARKUP DIVIDE BY DIFFERENT THINGS, AND THAT IS THE WHOLE PROBLEM. Markup is profit as a share of what the item COST you. Margin is profit as a share of what you SOLD it for. Same profit, different denominator, so they can never be equal above zero - and markup is always the larger-looking number, which is why it is the one people quote and the one that flatters a price. THE CONVERSION IS SIMPLE AND WORTH MEMORISING. Margin = markup ÷ (1 + markup). Markup = margin ÷ (1 − margin). So a 50% markup is a 33.3% margin, and getting a 50% MARGIN needs a 100% markup. If you have ever set prices at 'cost plus 30%' believing you were making 30%, you were making 23%. ⚠️ THE ERROR ONLY EVER RUNS ONE WAY. Because markup is the bigger number, mistaking one for the other means you charged LESS than you meant to, never more. That is why this is worth checking rather than assuming - the mistake does not announce itself, it just quietly compresses every margin in the business, and it compounds with volume. MARGIN IS THE FIGURE THAT MATTERS FOR RUNNING A BUSINESS, because it is the share of revenue you keep. Your fixed costs, your break-even and your ability to survive a bad month are all expressed against revenue, not against cost of goods. Markup is a pricing MECHANISM - a convenient way to set a price from a known cost - and it is fine for that as long as you know what margin it produces. AS MARGINS RISE THE GAP EXPLODES. At a 10% margin you need an 11% markup and the two look close enough to confuse harmlessly. At 50% you need 100%. At 80% margin you need a 400% markup. Anyone selling high-margin goods or services who reasons in markup is working with numbers that bear almost no resemblance to their accounts. THIS IS GROSS, NOT NET. Cost here means the direct cost of the thing sold. Rent, wages, software, insurance and everything else come out of the margin afterwards - so a healthy gross margin is not the same as a profitable business, and 'we make 40%' means very different things depending on which of the two someone means and which costs they have counted. THIS IS GENERAL INFORMATION AND NOT FINANCIAL ADVICE. Pricing decisions interact with tax, competition and your own costs in ways no calculator sees. If a pricing change matters to the business, it is worth talking through with a qualified adviser or accountant.

Common questions

What is the actual difference?

The denominator, and nothing else. Markup expresses profit as a share of what the item COST you; margin expresses the same profit as a share of what you SOLD it for. Since price is larger than cost, the same profit is a smaller fraction of price than of cost - so margin is always the smaller number and markup always the larger. They are equal only at zero. A $60 item sold for $100 makes $40 either way, but that is a 40% margin and a 66.7% markup, and both are correct descriptions of the same sale.

What is the conversion?

Margin equals markup divided by one plus markup. Markup equals margin divided by one minus margin. Worth memorising, because the two most useful cases are memorable: a 50% markup is a 33.3% margin, and a 50% margin requires a 100% markup. If you have ever priced at 'cost plus 30%' believing you were making 30%, the truth is 23%. The tool converts both ways at once so you can see which of the two any given number actually is.

Why does the mistake matter so much?

Because it only ever runs one way. Markup is the larger number, so mistaking one for the other always means you charged LESS than you intended, never more. It does not announce itself either - the sale still happens, the customer is happy, and the shortfall only shows up as a business that is somehow busier than it is profitable. And it compounds with volume: a few points of margin lost on every sale is the difference between a good year and a worrying one, which is why it is worth checking rather than assuming.

Which one should I actually use?

Both, for different jobs. Markup is a pricing MECHANISM - a convenient way to get from a known cost to a price - and it is perfectly good for that provided you know what margin it produces. Margin is the figure for running the business, because it is the share of revenue you keep, and your fixed costs, break-even point and ability to absorb a bad month are all measured against revenue rather than against cost of goods. Set prices with markup if that is easier; judge the business on margin.

Does the gap get worse at higher margins?

Dramatically, and this is where it stops being a rounding issue. At a 10% margin you need an 11% markup - close enough that confusing them costs little. At 50% margin you need a 100% markup. At 80% margin you need 400%. So anyone selling high-margin goods or services who reasons in markup is working with numbers that bear almost no resemblance to their accounts. The tool shows both conversions side by side precisely so the size of that divergence is visible at whatever level you actually operate.

Is this gross or net?

Gross. Cost here means the direct cost of the thing sold, so rent, wages, software, insurance, marketing and everything else come out of the margin afterwards. A healthy gross margin is therefore not the same as a profitable business - it is the starting point from which everything else is paid. It also means that when someone says 'we make 40%', the statement is ambiguous twice over: which of the two numbers they mean, and which costs they have already deducted.

How do I price to a target margin?

Divide the cost by one minus the margin, not multiply by one plus it. Cost ÷ (1 − margin) is the correct move, and the multiply is exactly the mistake this page exists for. On a $60 cost, a 50% target margin means $60 ÷ 0.5 = $120, while applying 50% as a markup gives $90 - a $30 shortfall per sale, on every sale. The tool reports that gap directly, because seeing the money is more persuasive than seeing the percentages.

Take it further with AI

Copy this into ChatGPT or Claude with your own numbers filled in. It hands over the figures this calculator worked out, so the answer is built on real arithmetic instead of a guess.

I used the Profit Margin vs Markup Calculator at https://www.bfcbrilliance.com/tools/profit-margin-vs-markup-calculator.

What I entered:
- What it costs you ($): ___
- What you sell it for ($): ___
- A margin you are aiming for (%): ___
- Or a markup you are applying (%): ___

What it calculated:
- Your margin: ___
- Your markup: ___
- Profit per sale: ___
- The markup you entered is really this margin: ___
- The margin you want needs this markup: ___

Use those figures as given — they are already worked out, so please don't recalculate or estimate your own. Help me turn them into a plan: what to buy or do, in what order, roughly what it should cost, and the mistakes people most often make with this job.
