Calculate profit margin, markup, selling price, revenue, cost, and pricing scenarios.
Enter the values and review the result.
How much it costs you to produce or buy the item.
The price at which you sell the item to customers.
Calculation assumptions
- *Profit is calculated as revenue minus cost.
- *Profit margin uses revenue as the base; markup uses cost as the base.
- *Selling price from target margin = cost / (1 - margin rate).
- *Selling price from target markup = cost x (1 + markup rate).
- *Real profit can differ because of taxes, fees, discounts, refunds, labor, overhead, shipping, inventory loss, and changing costs.

What is profit margin?
Profit margin shows how much of each sales dollar remains after the cost you enter. It is useful for checking product pricing, service quotes, discounts, and small-business unit economics.
This calculator focuses on gross profit planning. Real profit can change after overhead, labor, taxes, payment processing fees, shipping, returns, discounts, inventory loss, and changing costs.
Profit 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.
Example: if cost is $60 and selling price is $100, profit is $40. Margin is $40 / $100 = 40%, while markup is $40 / $60 = 66.67%.
How to calculate selling price from target margin
To price from a target margin, use selling price = cost / (1 - margin rate). A $60 cost at a 40% target margin gives $60 / 0.60 = $100.
To price from markup, use selling price = cost x (1 + markup rate). A $60 cost with a 50% markup gives $60 x 1.50 = $90.
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%
Discount, break-even, and sales tax connections
Discounts reduce selling price and can shrink margin quickly. Use the Discount Calculator to test sale prices, then check the remaining margin here.
For fixed costs and contribution margin, use the Break-even Calculator. For checkout tax estimates, use the Sales Tax Calculator. Sales tax collected is generally a pass-through amount, not ordinary business revenue, but tax treatment can vary.
For percentage formulas, compare rates with the Percentage Calculator.

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.
