💰 How to Calculate Margin Percentage
Margin percentage (or profit margin) is a key business metric that tells you how much profit you make from your revenue — expressed as a percentage. It’s used widely in retail, manufacturing, services, and e-commerce.
🧮 Formula to Calculate Margin Percentage
There are two common formulas depending on how you define margin:
1. Gross Profit Margin (Most Common)
Margin %=(Selling Price−Cost PriceSelling Price)×100\text{Margin \%} = \left( \frac{\text{Selling Price} – \text{Cost Price}}{\text{Selling Price}} \right) \times 100Margin %=(Selling PriceSelling Price−Cost Price)×100
Example:
- Selling Price = $100
- Cost Price = $70
- Profit = $30
\text{Margin \%} = \left( \frac{30}{100} \right) \times 100 = \textbf{30%}
2. Markup vs. Margin – What’s the Difference?
People often confuse markup and margin. Here’s how they differ:
- Margin is based on selling price
- Markup is based on cost price
Markup Formula:
Markup %=(Selling Price−CostCost)×100\text{Markup \%} = \left( \frac{\text{Selling Price} – \text{Cost}}{\text{Cost}} \right) \times 100Markup %=(CostSelling Price−Cost)×100
If Cost = $70 and Selling Price = $100:
- Markup = (30 / 70) × 100 = 42.86%
- Margin = (30 / 100) × 100 = 30%
