Margin Calculator
Quickly calculate profit margin, markup, and selling price
What is a Margin Calculator?
A margin calculator helps businesses and entrepreneurs determine the profitability of their products. By entering cost and selling price (or desired margin), you instantly see the gross profit, profit margin percentage, and markup percentage. This tool supports three modes:
- Margin % – calculate profit margin and markup from cost and selling price.
- Selling Price – find the minimum selling price to achieve a target margin.
- Cost – reverse‑calculate the maximum cost to maintain a certain margin.
Gross Profit Margin Formula
Understanding the math is key. The most common formulas are:
- Gross Profit = Selling Price – Cost
- Margin (%) = (Gross Profit / Selling Price) × 100
- Markup (%) = (Gross Profit / Cost) × 100
For example, if a product costs $50 and sells for $80:
- Gross Profit = $30
- Margin = ($30 / $80) × 100 = 37.5%
- Markup = ($30 / $50) × 100 = 60%
How to Use the Calculator
Choose the tab that matches what you know:
- Margin % – enter your cost and selling price; the results update instantly.
- Selling Price – enter your cost and desired margin (e.g., 30%); the tool shows the required selling price.
- Cost – enter your selling price and desired margin; the tool calculates the maximum cost you can pay.
All results are recalculated as you type. Use the Reset button to start over.
Why Margin Matters
Profit margin is a core metric for any business. It tells you how much of each sale is actual profit. A healthy margin allows you to cover overhead, reinvest, and grow. Markup, on the other hand, is often used for pricing strategies but can be confused with margin – remember, a 50% markup does not equal a 50% margin!
Frequently Asked Questions
What is the difference between margin and markup?
Margin is the percentage of the selling price that is profit. Markup is the percentage of the cost that is added to get the selling price. They are related but not the same.
Can I calculate margin with a fixed markup?
Yes. If you know your cost and markup percentage, you can enter them into the Selling Price tab using the corresponding margin. Use our tool to convert markup to margin easily.
