Profit Margin Calculator

How to Calculate Profit Margin

Want to do the math yourself? It’s easy! Here’s the process our calculator follows:

1. Find Your Cost: First, determine the total cost of your item. This is often called the “Cost of Goods Sold” (COGS). Let’s say your cost is $60.
2. Know Your Revenue: This is the final price you sold the item for. Let’s use $100.
3. Calculate Net Profit: Subtract your cost from your revenue. This is your profit in dollars. $100 (Revenue) - $60 (Cost) = $40 (Net Profit)
4. Divide Profit by Revenue: Take your net profit ($40) and divide it by your total revenue ($100). $40 / $100 = 0.40
5. Convert to a Percentage: Finally, multiply that number by 100 to get your profit margin. 0.40 * 100 = 40%

First, to find the Net Profit:

NetProfit = Revenue − Cost

Then, to find the Profit Margin:

ProfitMargin(%) = (RevenueNetProfit​) × 100

Frequently Asked Questions (FAQs)

1. What’s the real difference between profit margin and markup?

That’s a great question, as they’re often mixed up!

• Profit Margin (like the 40% in our example) shows your profit as a percentage of your revenue (the final sale price). It answers, “How much of my sale price is profit?”
• Markup (like the 66.67% in our example) shows your profit as a percentage of your cost. It answers, “How much did I mark this up from what I paid?” Markup will always be a higher percentage than margin.

2. Can I use this calculator for services, not just physical products?

Absolutely! For “Cost,” just add up all your direct expenses to deliver that service (like software subscriptions, travel, or fees for subcontractors). For “Revenue,” use the total amount you invoiced your client for the project.

3. Why do I need both Net Profit and Net Profit Margin?

Think of it this way: Net Profit is the simple, hard-dollar amount you have left over (e.g., $40). Net Profit Margin is a percentage (e.g., 40%) that tells you how efficiently you made that profit. The margin is much better for comparing the profitability of two different items (e.g., a $10 item vs. a $1000 item).
