This is one of the most common — and most costly — pricing mistakes small business owners make. Confusing profit margin with markup can mean pricing your products lower than you think and silently losing money on every sale.
The Core Difference
Markup is profit calculated as a percentage of your cost.
Margin is profit calculated as a percentage of your selling price.
Same profit, different base — and the percentages are never equal. For any given profit, margin is always the smaller number.
The Formulas
Markup % = (Selling Price − Cost) ÷ Cost × 100
Margin % = (Selling Price − Cost) ÷ Selling Price × 100
A Worked Example
Say your cost is Rs. 100 and you sell for Rs. 150.
- Profit = Rs. 150 − Rs. 100 = Rs. 50
- Markup = 50 ÷ 100 × 100 = 50%
- Margin = 50 ÷ 150 × 100 = 33.3%
Same Rs. 50 profit — very different percentages.
Side-by-Side Comparison
| Metric | Formula | Example (Cost Rs.100, Price Rs.150) |
|---|---|---|
| Markup | (Price − Cost) ÷ Cost | 50% |
| Margin | (Price − Cost) ÷ Price | 33.3% |
Why This Mistake Costs Money
If a business owner wants a 50% profit margin but mistakenly applies a 50% markup instead, they'll actually only achieve a 33.3% margin — undershooting their real profitability target without realizing it. Across thousands of transactions, that difference adds up to significant lost revenue.
Which One Should You Use?
- Use margin when analyzing overall business profitability and comparing against revenue.
- Use markup when setting individual product prices from your cost base.
- Always know which one you're calculating — many spreadsheet and pricing mistakes come from mixing the two.
Practical Pricing Tips
- Set your target margin first based on market and overheads.
- Convert that margin to markup before applying to cost.
- Review margins regularly — rising material costs can silently reduce profit.
- Use a calculator to avoid manual errors.

Frequently Asked Questions
Q: Can margin and markup ever be equal?
A: No. For the same profit, margin will always be lower than markup because it uses a larger base (selling price vs cost).
Q: How do I convert markup to margin?
A: Margin = Markup ÷ (1 + Markup). For example, 50% markup = 50 ÷ 1.50 = 33.3% margin.
Q: Which is more important for my business?
A: Both matter. Use markup for pricing, but track margin to understand true profitability.
