Calculate Margin & Markup
Profit Breakdown
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
Quick Reference: Margin vs Markup Equivalents
Notice how a 50% margin requires a massive 100% markup.
10% Margin
Requires an 11.1% Markup
20% Margin
Requires a 25% Markup
33.3% Margin
Requires a 50% Markup
50% Margin
Requires a 100% Markup
75% Margin
Requires a 300% Markup
90% Margin
Requires a 900% Markup
Real-World Industry Averages
Restaurants & Food Service
Restaurants typically operate on incredibly thin 3% to 5% net margins, though their markup on individual ingredients (like beverages or pasta) can be 300% or higher.
Retail Clothing
Apparel retailers often aim for a 50% margin (which is a 100% markup, commonly referred to as "keystone pricing"). When it comes time for seasonal sales, they rely on calculating precise markdowns, which you can do using our Discount Calculator to avoid taking a loss.
SaaS (Software as a Service)
Software companies enjoy massive margins because the cost to replicate the product is near zero. Gross margins often hover between 70% and 90%.
Grocery Stores
Supermarkets rely on high volume rather than high profit. Their overall profit margins are usually between 1% and 3%.
Frequently Asked Questions
1. Can profit margin be over 100%?
No. Profit margin cannot mathematically exceed 100% because the profit cannot be larger than the total revenue itself. However, Markup can easily exceed 100% if you sell an item for more than double its original cost.
2. What is Gross Profit vs Net Profit?
Gross Profit only deducts the direct Cost of Goods Sold (COGS) from the revenue. Net Profit deducts everything—including operating expenses, marketing, taxes, payroll, and rent. This calculator computes Gross Profit. If you need to deduct specific sales taxes from your revenue first, try using our Tax Percentage Calculator.
3. How do I calculate profit margin in Excel?
If cell A1 is your Cost and cell B1 is your Selling Price, use this formula to find the Margin: =(B1-A1)/B1. Then format the cell as a percentage.
4. What happens if my cost is higher than my selling price?
You have taken a loss. Our calculator will display the results in red and show a negative percentage margin, indicating the degree of the financial loss.
