Markup vs Margin: Differences, Formulas and Conversion Table
.png)
You want a 30% profit, so you add 30% to the cost and call it a day. It feels right. It’s also wrong, because you’ve ended up with a margin closer to 23%, and over a few hundred sales that gap eats thousands of rupees. The culprit is a pair of words that sound like the same thing: markup and margin.
Quick take
- Markup is profit divided by cost. Margin is profit divided by selling price.
- For the same sale, markup is always the bigger number. A 25% margin is a 33.33% markup.
- Add 30% to a ₹700 cost and you get ₹910, which is only a 23.08% margin. A real 30% margin needs ₹1,000.
- To convert: markup = margin ÷ (1 − margin), and margin = markup ÷ (1 + markup).
Below I’ll explain both terms in plain language, give you the formulas and a conversion table, and walk through a pricing mistake in rupees. There’s also a small converter in the middle, so you can test your own numbers.
What markup means
Markup is how much you add on top of what something cost you. It starts from your cost price, which is why traders and wholesalers love it. Buy a bag for ₹600, sell it for ₹800, and you’ve added ₹200, which is a third of ₹600.
Markup % = (Selling price − Cost) ÷ Cost × 100
So that’s 200 ÷ 600, or 33.33%. Markup is handy when you’re buying stock, because the supplier’s price is right there in front of you and you just add your percentage.
What margin means
Margin is how much of the final price is profit. It starts from what the customer pays. Sell the same bag for ₹800, keep ₹200, and a quarter of the price is profit.
Margin % = (Selling price − Cost) ÷ Selling price × 100
That’s 200 ÷ 800, or 25%. Margin is the number that shows up in your accounts, because it tells you how much of each sale stays with you. It can never reach 100%. Markup can go well past 100% on things sold for many times their cost.
Why the numbers differ
The profit is identical. Only the number you divide by changes. When you’re making a profit, cost is smaller than price, so dividing by cost gives you the bigger percentage. A 50% markup means the profit is half your cost, but that same profit is only a third of the price, so the margin is 33.33%.
The gap widens as the percentages climb. At low levels the two are close, and at high levels they drift far apart. That’s exactly why people get caught: the error looks harmless on a 10% profit and gets expensive on a 40% one.
Conversion table
Here’s the same profit written both ways. Find the number you know and read across.
| Markup on cost | Equals margin on price | Margin on price | Equals markup on cost |
|---|---|---|---|
| 10% | 9.09% | 10% | 11.11% |
| 20% | 16.67% | 20% | 25% |
| 25% | 20% | 25% | 33.33% |
| 30% | 23.08% | 30% | 42.86% |
| 40% | 28.57% | 40% | 66.67% |
| 50% | 33.33% | 50% | 100% |
| 100% | 50% | 60% | 150% |
The two formulas behind it are easy. To turn margin into markup, divide the margin by one minus the margin: for 20%, that’s 0.20 ÷ 0.80, or 25%. To go the other way, divide the markup by one plus the markup: for 25%, that’s 0.25 ÷ 1.25, or 20%.

The mistake that costs real money
Say a gadget costs you ₹700 and you want a 30% margin. You think, 30% of ₹700 is ₹210, so I’ll charge ₹910. Sounds fine until you check: profit ₹210 on a price of ₹910 is 23.08%. You aimed for 30 and got 23.
The right price divides the cost by one minus 0.30. That’s 700 ÷ 0.70, which is ₹1,000. Now your profit is ₹300, and ₹300 really is 30% of ₹1,000. The difference is ₹90 a unit. Sell 500 and the mistake has cost you ₹45,000 of profit you thought you were making. To price from a margin properly, see how to calculate selling price.
Which one should you use?
Neither is better. They do different jobs, and sensible owners use both.
- Markup is quick when you’re pricing stock from a supplier’s list and want a rule like “add 40% to everything”.
- Margin is what you want for checking profit, comparing products and reading your accounts.
- Set targets in margin. If the business needs a 25% margin to cover its costs, price with the margin formula rather than adding 25% to cost.
- Always name which one. When a supplier or partner says “30% profit”, ask whether that’s on cost or on price.
Slip-ups to watch for
- Treating the two as the same. They only match at zero. Everywhere else markup is higher.
- Adding margin to cost. Margin belongs on the selling price. Use cost ÷ (1 − margin).
- Mixing them in one sheet. Label every column, so a number never gets read as the wrong kind.
- Forgetting discounts. A markup that works at list price may not survive a 10% discount. Recheck at the sale price, and see how to improve profit margin for what discounts really cost.
- Trusting a bad cost. Both percentages are only as good as the cost under them. Include packaging, freight and fees.
Frequently asked questions
What’s the difference between markup and margin?
Markup is profit as a percentage of cost. Margin is profit as a percentage of the selling price. Same profit, different base, so markup is the bigger number.
How do I convert markup to margin?
Divide the markup by one plus the markup. A 50% markup becomes 0.50 ÷ 1.50, a 33.33% margin.
How do I convert margin to markup?
Divide the margin by one minus the margin. A 40% margin becomes 0.40 ÷ 0.60, a 66.67% markup.
Can margin be higher than 100%?
No. It’s a share of the selling price, so it can’t reach 100% unless your cost is zero. Markup can go above 100%.
Why is a 100% markup only a 50% margin?
A 100% markup means you sell at double your cost. Buy for ₹500, sell for ₹1,000, and the ₹500 profit is half of the price.
Which is better for pricing a product?
Markup is quick for pricing from cost. Margin is better for confirming you’ll earn the profit you need. Plenty of owners price with markup and then check the margin.
Try your own products
Pick three products and write down the cost and the price of each. Run them through the converter above and look at both numbers. If you’ve been pricing with a round markup, check whether the margin is enough to cover your costs, or check a product’s full numbers in the profit margin calculator. Fixing the price of one best seller can matter more than a month of penny-pinching.
