What Is Profit Margin Calculator?
A profit margin calculator determines how much of each dollar of revenue represents profit. It computes three key metrics: gross profit margin ((Revenue − COGS) / Revenue × 100), which shows profitability before operating expenses; net profit margin ((Revenue − COGS − Expenses) / Revenue × 100), which shows overall profitability; and markup ((Revenue − COGS) / COGS × 100), which expresses profit as a percentage of cost. These metrics are essential for pricing products, comparing business performance across companies or industries, and tracking financial health over time. A high gross margin indicates efficient production, while a healthy net margin indicates overall operational efficiency.

Technical Guide
Gross Profit = Revenue − COGS. Gross Margin = Gross Profit / Revenue × 100. Net Profit = Revenue − COGS − Operating Expenses. Net Margin = Net Profit / Revenue × 100. Markup = Gross Profit / COGS × 100. The critical distinction between margin and markup: margin is profit as a percentage of revenue (the selling price), while markup is profit as a percentage of cost. A 50% markup on a $100 cost gives a $150 price and a 33.3% margin, not 50%. The relationship is: Markup% = Margin% / (100% − Margin%). Industry-standard margins vary widely: software companies may have 80%+ gross margins, while grocery stores operate on 2-5% net margins. Both are viable when revenue volumes are appropriate.
Tips & Best Practices
- 1Margin ≠ Markup — a 50% markup is only a 33.3% margin
- 2Compare your margins to industry benchmarks for context
- 3Gross margin shows production efficiency; net margin shows overall efficiency
- 4Higher revenue doesn't always mean higher margins
- 5Track margins over time to spot trends in profitability
