Free Tools Margin Calculator

A Margin Calculator is a financial tool used to calculate the profit margin of a product, service, or business. It shows how much profit is earned from a sale after accounting for costs.

Main Formula

$$\text{Profit Margin (\%)} = \frac{\text{Selling Price} – \text{Cost Price}} {\text{Selling Price}} \times 100$$Profit Margin (%)=Selling PriceSelling Price−Cost Price​×100

Where:

• Selling Price (Revenue) = The price charged to customers
• Cost Price (Cost of Goods Sold/COGS) = The amount spent to produce or purchase the item
• Profit = Selling Price − Cost Price

Example

Suppose:

• Cost to produce a product = $40
• Selling price = $100

Profit:$$100 – 40 = 60$$100−40=60

Profit margin:$$\frac{60}{100}\times100 = 60\%$$10060​×100=60%

The profit margin is 60%.

Types of Margins a Calculator May Measure

1. Gross Profit Margin$$\frac{\text{Revenue – COGS}}{\text{Revenue}}\times100$$RevenueRevenue – COGS​×100

Measures profit after direct production costs.

2. Operating Profit Margin$$\frac{\text{Operating Income}}{\text{Revenue}}\times100$$RevenueOperating Income​×100

Measures profit after operating expenses.

3. Net Profit Margin$$\frac{\text{Net Income}}{\text{Revenue}}\times100$$RevenueNet Income​×100

Measures the final profit after all expenses.

What a Margin Calculator Does

You enter:

• Cost price
• Selling price (or revenue)
• Optional expenses

The calculator provides:

• Profit amount
• Profit margin percentage
• Markup percentage (in some calculators)
• Break-even information (optional)

Margin vs. Markup

Metric	Formula	Based On
Margin	Profit ÷ Selling Price	Sales revenue
Markup	Profit ÷ Cost Price	Product cost

Example:

• Cost = $50
• Selling price = $100
• Profit = $50

Margin:$$50/100=50\%$$50/100=50%

Markup:$$50/50=100\%$$50/50=100%
