What Is Margin?
Margin is the percentage of revenue that remains after subtracting the cost of goods sold. It is one of the most important metrics in business because it tells you how much of every dollar in sales you actually keep as profit. A 40% margin means you keep $0.40 for every $1.00 in revenue, with the remaining $0.60 going toward costs.
The margin calculator above helps business owners, accountants, and financial analysts quickly determine their profit margin, markup percentage, and total profit. Whether you are pricing a single product or analyzing your entire business, understanding margin is critical for sustainable profitability.
Margin is based on selling price (profit / revenue), while markup is based on cost (profit / cost). A 50% markup is only a 33.3% margin. Confusing these two is one of the most common pricing mistakes in business.
How to Calculate Margin
Calculating margin is straightforward once you know the formula. You need just two inputs: your selling price (revenue) and your cost. The difference between these is your gross profit, and dividing that by revenue gives you the margin percentage.
- 1Gross Profit = $100 - $60 = $40
- 2Profit Margin = ($40 / $100) × 100 = 40%
- 3Markup = ($40 / $60) × 100 = 66.67%
- 4For every $1 in revenue, you keep $0.40 as profit
Margin vs. Markup Conversion Table
One of the biggest mistakes business owners make is confusing margin with markup. The table below shows how common margin percentages translate to markup percentages and vice versa. Use this as a quick reference when pricing your products.

|---|---|---|---|
| 10% | 11.1% | $1.11 | $0.10 |
| 20% | 25.0% | $1.25 | $0.20 |
| 25% | 33.3% | $1.33 | $0.25 |
| 30% | 42.9% | $1.43 | $0.30 |
| 33.3% | 50.0% | $1.50 | $0.33 |
| 40% | 66.7% | $1.67 | $0.40 |
| 50% | 100.0% | $2.00 | $0.50 |
| 60% | 150.0% | $2.50 | $0.60 |
| 75% | 300.0% | $4.00 | $0.75 |

Good Margin Benchmarks by Industry
Healthy profit margins vary significantly by industry. What is considered a strong margin in grocery retail would be considered poor in software. Understanding industry benchmarks helps you evaluate your business performance relative to peers.

Strategies to Increase Margin
Using Margin for Stock and Options Trading
In the world of investing and options trading, margin has a different meaning. Trading margin refers to borrowed funds from a broker to purchase securities. A margin account allows you to buy stocks with leverage, amplifying both gains and losses. For options traders, margin requirements determine how much capital you must maintain in your account to hold certain positions.
Under Regulation T in the United States, the initial margin requirement for stock purchases is 50%, meaning you can borrow up to half the purchase price. Maintenance margin is typically 25%, though most brokers require 30-40%. If your account equity falls below the maintenance margin, you will receive a margin call requiring you to deposit additional funds or liquidate positions.
