Most small business owners use "profit margin" and "markup" as if they mean the same thing. They don't. The formulas look similar, the words are often used interchangeably, and the results are quietly, consistently different — which means anyone pricing products based on the wrong one is systematically undercharging without knowing it.
The difference comes down to one thing: what number you're dividing by. Markup divides by cost. Margin divides by selling price. That single distinction changes the output enough to matter, especially when you're trying to hit a specific profit target.
This post explains both concepts with real numbers, shows exactly where people go wrong, and gives you the formulas you need to price correctly from here on out.

What is markup?
Markup is the amount you add on top of your cost to arrive at a selling price, expressed as a percentage of cost.
Markup = ($90 − $60) ÷ $60 × 100 = 50%
Markup is the natural tool for building a price from scratch. You know what something costs you, you add a percentage on top, and you get a selling price. It's intuitive, fast, and used widely in retail and wholesale pricing.
The catch: a 50% markup does not give you a 50% profit margin. That's the part most people miss.
What is profit margin?
Profit margin is the percentage of your selling price that you keep as profit — after covering the cost of the product or service.
Margin = ($90 − $60) ÷ $90 × 100 = 33.3%
The number is different from the markup even though the cost and price are identical. That's not a rounding issue — it's the formula. Margin tells you what portion of every dollar of revenue you're keeping. It's the metric that matters for evaluating business performance and financial health.
Why the difference between profit margin vs markup matters
Here's the mistake that trips people up: if you want a 40% profit margin on everything you sell, you might assume adding 40% to your cost gets you there. It doesn't.
You wanted 40%. You got 28.6%. On a low-volume business, that gap is manageable. On a high-volume one, it's the difference between a healthy business and a barely-breaking-even one.
To price for a target margin rather than a target markup, work backwards from the margin:
Selling price = $80 ÷ (1 − 0.40) = $80 ÷ 0.60 = $133.33
Check: ($133.33 − $80) ÷ $133.33 = 40% ✓
That formula is the one to memorize if you care about hitting a specific profit target rather than just applying a multiplier to cost.
Which one should you use?
Use markup for pricing decisions. When you're building a price from a known cost — especially in product-based businesses — markup is simpler to apply. You pick a multiple, apply it consistently, and your prices are set. Retail and wholesale industries typically talk in markup terms for this reason.
Use margin for performance evaluation. When you're analyzing whether your business is profitable, comparing performance across product lines, or presenting financials, margin is the right metric. It tells you what percentage of revenue you're actually keeping — which is what investors, lenders, and accountants want to know.
The practical move: decide on a target margin for your business, then use the reverse formula to calculate the markup you need to apply consistently to hit it. That way both numbers stay aligned.
Markup to margin: quick reference
If you know your markup and want to know what margin it actually produces, or vice versa, this table saves you the math:
| Markup | Equivalent profit margin |
|---|---|
| 20% | 16.7% |
| 25% | 20.0% |
| 33% | 25.0% |
| 50% | 33.3% |
| 100% | 50.0% |
| 200% | 66.7% |
To convert in either direction: Margin = Markup ÷ (1 + Markup) and Markup = Margin ÷ (1 − Margin). Use decimals, not percentages, in the formulas.

Frequently asked questions
Is a 50% markup the same as a 50% profit margin?
No. A 50% markup gives you a 33.3% profit margin. The formulas use different denominators — markup divides by cost, margin divides by selling price. Always check which one you're working with before you set a price.
What is a good profit margin for a small business?
It depends heavily on the industry. Retail products typically run 20–40% gross margin. Service businesses often run higher since there's little or no cost of goods. Software and digital products can reach 60–80%. Compare your numbers to your industry benchmark rather than a generic rule.
How do I convert markup to margin?
Use the formula: Margin = Markup ÷ (1 + Markup). For a 50% markup: 0.5 ÷ 1.5 = 33.3% margin. For a 100% markup: 1.0 ÷ 2.0 = 50% margin. Always use decimals, not percentages, when plugging into the formula.
How do I convert margin to markup?
Use the formula: Markup = Margin ÷ (1 − Margin). For a 40% margin: 0.4 ÷ 0.6 = 66.7% markup. For a 50% margin: 0.5 ÷ 0.5 = 100% markup.
What is the difference between gross margin and net margin?
Gross margin is revenue minus the direct cost of goods or services, before overhead, salaries, or other operating expenses. Net margin is revenue minus everything — all expenses included. Most pricing decisions use gross margin; net margin tells you how profitable the overall business is once all the bills are paid.
