What Is a Profit Margin?
A profit margin will demonstrate the percentage of your selling price that will be profit. Consider it as so:
If you sell something for $100 but it costs you $70 to make, your profit is $30. But your margin is: $30 ÷ $100 = 30%
So even though you earned $30, your margin tells you how efficient your business is at turning revenue into real income.
Margin Formula (How It Works)
Here’s the exact formula our calculator uses:
Margin (%) = (Selling Price – Cost Price) / Selling Price × 100
