What is Profit Percentage?
Profit percentage is a financial metric that indicates the financial health and pricing strategy of a business. However, the business world uses two completely different metrics to track this: Profit Margin and Markup.
While both metrics require the exact same inputs (Cost Price and Selling Price), they provide different insights. Mixing them up is one of the most common and costly mistakes new business owners make when setting retail prices.
The Big Difference: Margin vs. Markup
Here is the easiest way to understand the difference between the two terms:
📉 Profit Margin
- What it is: Shows how much of your final revenue is actual profit.
- The Math: Gross Profit ÷ Selling Price
- Maximum: Can never exceed 100%.
Viewpoint: Looking backward from the cash register to see what you keep.
📈 Markup
- What it is: Shows how much you increased the cost to arrive at the sale price.
- The Math: Gross Profit ÷ Cost Price
- Maximum: Can be infinite (e.g., 500% markup).
Viewpoint: Looking forward from the factory to set the price tag.
How to Calculate Profit Margin
Formula: ((Revenue - Cost) ÷ Revenue) × 100
To find your margin, you first subtract your cost from the selling price to find your Gross Profit. Then, divide that profit by the Selling Price.
Example: You buy a shirt for $50 and sell it for $100.
1. Gross Profit: $100 - $50 = $50
2. Margin Math: $50 ÷ $100 = 0.50
3. Final Margin: 0.50 × 100 = 50% Margin

Frequently Asked Questions
1. Can profit margin be over 100%?
No. Profit margin cannot mathematically exceed 100% because profit cannot exceed total revenue. However, Markup can easily exceed 100%.
2. What is Gross Profit vs Net Profit?
Gross Profit deducts COGS from revenue. Net Profit deducts all expenses (operating, taxes, rent). To deduct sales tax first, use our Tax Percentage Calculator.
3. How do I calculate profit margin in Excel?
If cell A1 is Cost and B1 is Selling Price, use: =(B1-A1)/B1 and format as percentage.
4. What happens if cost is higher than selling price?
You have taken a financial loss. The calculator will display the result in red with a negative percentage.
