Markup vs Margin: The Difference and How to Convert
The short answer
Markup and margin use the same profit but divide it by different numbers.
- Markup = profit ÷ cost. It answers “how much did I add on top of what I paid?”
- Margin = profit ÷ selling price. It answers “how much of each sale do I keep?”
Buy something for $40 and sell it for $60, and the $20 profit is a 50% markup (20 ÷ 40) but only a 33.3% margin (20 ÷ 60). Same sale, two percentages. Because the price is bigger than the cost whenever you make a profit, markup is always the larger number.
Margin is the one on your books. Accountants calculate gross margin as gross profit divided by revenue, as the Corporate Finance Institute defines it, so when an accountant, lender or industry report talks about a “40% margin,” they mean 40% of the selling price.
The conversion formulas
Write the percentages as decimals (40% = 0.40):
Margin = markup ÷ (1 + markup)
Markup = margin ÷ (1 − margin)
And the two pricing formulas you will use most:
Price from a markup = cost × (1 + markup)
Price from a target margin = cost ÷ (1 − margin)
Check the first pair with the $40 item: a 0.50 markup gives 0.50 ÷ 1.50 = 0.333, a 33.3% margin. Going back, 0.333 ÷ 0.667 = 0.50.
Markup and margin side by side
| Markup on cost | Margin on price | Multiply cost by | $10 cost sells for |
|---|---|---|---|
| 25% | 20.0% | 1.25 | $12.50 |
| 33.3% | 25.0% | 1.333 | $13.33 |
| 50% | 33.3% | 1.50 | $15.00 |
| 66.7% | 40.0% | 1.667 | $16.67 |
| 100% | 50.0% | 2.00 | $20.00 |
| 150% | 60.0% | 2.50 | $25.00 |
| 200% | 66.7% | 3.00 | $30.00 |
| 300% | 75.0% | 4.00 | $40.00 |
Two patterns worth remembering. Doubling the cost (a 100% markup) only gives a 50% margin. And margin can never reach 100% while an item costs you anything, while markup has no ceiling.
Worked example: pricing a candle for a 60% margin
A small candle business works out its landed cost per candle: wax, jar, wick, fragrance, label and its share of inbound shipping come to $12.00. The owner has looked at her rent, software and booth fees and decided she needs a 60% gross margin to cover them and pay herself.
The right way: price = cost ÷ (1 − margin) = $12.00 ÷ 0.40 = $30.00.
Check it: $30.00 − $12.00 = $18.00 profit, and $18.00 ÷ $30.00 = 60%. The markup on that sale is $18.00 ÷ $12.00 = 150%.
The common mistake: she hears “60%” and adds 60% to the cost. That gives $12.00 × 1.60 = $19.20. The profit is $7.20, and the margin is $7.20 ÷ $19.20 = 37.5%, not 60%.
The gap is easier to see per $10,000 of sales:
| Pricing | Price | Margin | Gross profit per $10,000 of sales |
|---|---|---|---|
| Cost ÷ 0.40 (correct) | $30.00 | 60% | $6,000 |
| Cost × 1.60 (mix-up) | $19.20 | 37.5% | $3,750 |
Same revenue, $2,250 less to pay the bills with. If her overheads really take 60 cents of every sales dollar, the mix-up means she loses money on every candle while every sale looks profitable.
Fees come out of the price, not the cost
Card processing and marketplace fees are usually a percentage of the selling price, so they eat margin directly. To build them in, subtract the fee rate along with the margin:
Price = cost ÷ (1 − target margin − fee rate)
With an example fee of 3% of the price (check your own processor’s rate), the candle needs $12.00 ÷ (1 − 0.60 − 0.03) = $12.00 ÷ 0.37 = $32.43. Check: the fee is $0.97, leaving $32.43 − $12.00 − $0.97 = $19.46 of profit, which is 60.0% of the price.
At the original $30.00, the same 3% fee ($0.90) would cut the kept margin to $17.10 ÷ $30.00 = 57%.
What a discount really does to margin
Margin also explains why discounts hurt more than they look. Take the $30.00 candle at a 60% margin and run a 20% off sale:
- New price: $30.00 × 0.80 = $24.00.
- Profit: $24.00 − $12.00 = $12.00, down from $18.00.
- Margin: $12.00 ÷ $24.00 = 50%.
A 20% price cut removed a third of the profit on each candle. To make the same gross profit during the sale, she has to sell 1.5 times as many ($18.00 ÷ $12.00). That is the number to think about before deciding a discount will “pay for itself.”
Which one should you use?
Use markup at the point of pricing when you think in terms of cost: it is quick and easy to apply to a supplier invoice.
Use margin for planning and for anything you compare with your financial statements, a loan application or an industry benchmark. It tells you what share of every sale is left to cover overheads and profit.
The safest habit: decide on the margin you need, convert it to a markup once, and use that markup at the till. A 40% margin is a 66.7% markup, a 50% margin is a 100% markup, a 60% margin is a 150% markup.
Common mistakes
- Treating “markup” and “margin” as the same word. A 40% markup is only a 28.6% margin (0.40 ÷ 1.40).
- Using supplier cost instead of landed cost. Shipping in, duties and packaging are part of the cost of each item.
- Forgetting percentage fees. They come off the price and shrink the margin you keep.
- Expecting margin to cover everything. Gross margin is before rent, wages and software. Net margin is what is left after them, and it is always lower.
- Discounting without re-running the margin. A sale price can quietly drop below what your overheads need.
When to get a professional
If you are setting prices for a new product line, applying for financing, or your margins look healthy but the bank balance does not, an accountant can separate cost of goods sold from overheads properly and show you your real gross and net margins. That split also matters at tax time.
For day-to-day pricing, the markup calculator turns a cost and markup into a price and shows the margin it gives, and the profit margin calculator works out the price you need for a target margin, or the most you can pay a supplier and still hit it.
