Margin vs. Markup
Many people confuse margin and markup, but they are different. Margin is the ratio of profit to the selling price. Markup is the ratio of profit to the cost price.
Profit = Revenue - Cost. Profit Margin = Profit / Revenue x 100. Markup = Profit / Cost x 100.
Why profit margin matters
Profit margin shows how much of each sales dollar remains after the cost you enter. It is useful for checking pricing, comparing product lines, and spotting low-margin offers.
Actual margins can differ after taxes, fees, refunds, shipping, payment processing, discounts, overhead, and other business costs.
Example calculation
For a product that costs $80 to make and sells for $120:
- Gross Profit:$120 - $80 = $40
- Profit Margin:($40 / $120) × 100 = 33.3%
- Markup:($40 / $80) × 100 = 50%
Common mistakes
- Using cost as the base for margin instead of revenue.
- Confusing markup with margin when setting prices.
- Leaving out overhead, discounts, payment fees, returns, shipping, or taxes.
- Treating gross margin as net profit after all business expenses.

Frequently Asked Questions
Common questions about Profit Margin Calculator and how to read the result.
What is a good profit margin?
It depends on industry, pricing model, overhead, and risk. Compare margins against your own costs and similar businesses instead of relying on one universal number.
Can profit margin be negative?
Yes. If your cost is higher than your selling price, your margin will be negative, indicating a loss on every sale.
Does this include overhead costs?
This calculator finds 'Gross Margin'. To find 'Net Margin', you would need to subtract all other expenses like rent, salaries, and taxes from your profit.
How do I increase my margin?
You can increase your margin by either raising your selling price or finding ways to reduce your production or acquisition costs.
What is the profit margin formula?
Profit Margin = (Revenue - Cost) / Revenue x 100. Revenue must be greater than zero for the formula to work.
Is markup the same as margin?
No. Markup compares profit with cost, while margin compares profit with revenue. The percentages are different even with the same profit.
