🔁 Markup to Margin Converter

This converter is for general education and quick estimates only. It assumes a single product cost and a single selling price with no discounts, returns, shipping or overhead included. The result is not accounting or financial advice, confirm your real numbers with your bookkeeping records and speak to a qualified accountant before setting prices.
Markup and margin both describe profit, but they are measured against different bases, so the same dollar of profit gives two different percentages. This converter turns a markup percentage into its matching profit margin percentage, or a margin back into the markup you would need to charge. Enter one number, pick a direction, and read the answer with the exact working shown beneath it.
What is the Markup to Margin Converter?
Markup and margin are two ways of expressing the same profit, and confusing them is one of the most common pricing mistakes in retail and ecommerce. Markup is profit measured against cost: if an item costs 100 and you sell it for 150, the 50 profit is a 50% markup because it is 50% of the cost. Margin is that same 50 profit measured against the selling price, so it is 50 ÷ 150, or about 33%. The profit in dollars is identical, only the denominator changes.
Because the selling price is always larger than the cost (assuming you make a profit), the margin percentage is always smaller than the markup percentage. The two are linked by a simple pair of formulas: margin = markup ÷ (1 + markup) and markup = margin ÷ (1 − margin), where both percentages are written as decimals first. A 50% markup (0.5) becomes a 0.5 ÷ 1.5 = 33.33% margin, and a 33.33% margin (0.3333) maps back to a 0.3333 ÷ 0.6667 = 50% markup. The relationship is exact and reversible.
Why does the difference matter? If you want to hit a target margin (say your business needs a 40% margin to cover overhead and still profit), you must set the markup higher than 40%, in this case about 67%. Setting a 40% markup instead would leave you with only a 28.6% margin and a shortfall on every sale. Suppliers and POS systems often quote markup while your accountant thinks in margin, so being able to convert between them quickly keeps your pricing honest.
When to use it
- Converting a supplier or vendor markup into the profit margin it actually delivers on your shelf.
- Working out the markup you must charge to hit a target profit margin set by your business plan.
- Reconciling a point-of-sale system that quotes markup with accounting reports that show margin.
- Sanity-checking a pricing rule of thumb before applying it across a whole product catalog.
How to use the Markup to Margin Converter
- Choose a direction: markup to margin, or margin to markup.
- Enter the percentage you already know in the single input field.
- Use the quick-pick buttons for common values, or type your own.
- Read the converted percentage in the highlighted result, with the formula shown below it.
Formula & method
Worked examples
A supplier quotes a 50% markup. What profit margin does that give you?
- Write the markup as a decimal: 50% = 0.5
- margin = markup ÷ (1 + markup) = 0.5 ÷ (1 + 0.5)
- margin = 0.5 ÷ 1.5 = 0.3333
- Multiply by 100: 0.3333 × 100 = 33.33%
Result: 50% markup equals a 33.33% profit margin
Your business needs a 40% profit margin. What markup must you set?
- Write the margin as a decimal: 40% = 0.4
- markup = margin ÷ (1 − margin) = 0.4 ÷ (1 − 0.4)
- markup = 0.4 ÷ 0.6 = 0.6667
- Multiply by 100: 0.6667 × 100 = 66.67%
Result: A 40% margin requires a 66.67% markup
Common markup percentages and the profit margin each produces

| 25% | 20.00% |
| 50% | 33.33% |

Target margins and the markup you must charge to reach them

Common mistakes to avoid
- Treating markup and margin as the same number. A 50% markup is not a 50% margin, it is a 33.33% margin. Because markup is measured against cost and margin against price, the margin is always the smaller figure. Mixing them up overstates how much you actually keep.
- Setting markup equal to a target margin. If you need a 40% margin and set a 40% markup, you fall short, that markup only yields a 28.6% margin. To hit a 40% margin you must charge a 66.67% markup. Always convert before pricing.
- Ignoring costs left out of the calculation. This tool uses one product cost. Shipping, returns, payment fees and overhead all erode the margin you keep, so the converted figure is gross, not the profit that lands in your pocket.
- Trying to convert a 100% margin. Markup = margin ÷ (1 − margin) divides by zero when margin is 100%, which is mathematically undefined. A 100% margin would mean the item cost you nothing, so the markup is effectively infinite.
Glossary
- Markup
- Profit expressed as a percentage of cost. Markup = (price − cost) ÷ cost × 100.
- Margin (profit margin)
- Profit expressed as a percentage of the selling price. Margin = (price − cost) ÷ price × 100.
- Cost
- What you pay to acquire or produce the item, the base that markup is measured against.
- Selling price
- The amount you charge the customer, the base that margin is measured against.
- Gross profit
- The dollar difference between selling price and cost, before overhead and other expenses.
Frequently asked questions
What is the difference between markup and margin?
Markup measures profit against cost, while margin measures the same profit against the selling price. Because the price is larger than the cost, the margin percentage is always smaller than the markup percentage for the same sale. For example, a 50% markup is a 33.33% margin.
How do I convert markup to margin?
Use margin = markup ÷ (1 + markup), with markup written as a decimal. A 50% markup is 0.5, so margin = 0.5 ÷ 1.5 = 0.3333, which is a 33.33% margin. This converter does the arithmetic for you and shows the working.
How do I convert margin to markup?
Use markup = margin ÷ (1 − margin), with margin as a decimal. A 40% margin is 0.4, so markup = 0.4 ÷ 0.6 = 0.6667, which is a 66.67% markup. Switch the converter to margin-to-markup mode to get this instantly.
Why is margin always lower than markup?
Both describe the same dollar of profit, but margin divides it by the larger selling price while markup divides it by the smaller cost. A larger denominator gives a smaller percentage, so margin is always below the matching markup whenever you make a profit.
Can a margin be 100% or more?
A margin can approach but never reach 100%, since that would mean the item cost nothing. As margin nears 100% the required markup shoots toward infinity, which is why the formula markup = margin ÷ (1 − margin) is undefined at exactly 100%.
Which should I use to set my prices?
Most businesses plan around a target margin because it ties directly to the share of each sale they keep, but many pricing tools and suppliers quote markup. The practical answer is to set prices by markup and check the resulting margin, converting between the two so both agree.
