How to Calculate Profit Margin
Profit margin は計算されます as: Margin = ((Revenue − Cost) / Revenue) × 100.
For example, if you sell a product for $100 and it costs $60: Margin = ($100 − $60) / $100 × 100 = 40%.
Profit margin tells you what percentage of revenue is actual profit. Higher margins indicate more profitable products or services.
Margin vs Markup: What's the Difference?
Margin is profit as a percentage of revenue (selling price). Markup is profit as a percentage of cost.
For the same $60 cost and $100 price: Margin = 40%, Markup = 66.7%. They describe the same profit differently.
Margin is always lower than markup for the same transaction. A 50% markup equals a 33.3% margin.

Compare your margins to industry benchmarks rather than universal standards.
よくある質問
とは the difference between gross and net profit margin?
Gross margin subtracts only direct costs (COGS). Net margin subtracts all expenses including overhead, taxes, and interest.
How do I calculate margin from markup?
Margin = Markup / (1 + Markup). For a 50% markup: 0.50 / 1.50 = 33.3% margin.
Is a higher profit margin always better?
Generally yes, but very high margins may attract competition. Some businesses succeed with low margins and high volume (e.g., Walmart).
