Calculate Your Profit Margin
Calculate gross, operating, and net profit margins. Enter revenue and costs to see your profitability.
Formula
Profit Margin (%) = ((Revenue − Cost) / Revenue) × 100
How to Calculate
To calculate profit margin, subtract your total costs from your total revenue, then divide the result by your total revenue and multiply by 100. This gives you a percentage that represents how much of every dollar of revenue you keep as profit. There are three main types: gross margin (revenue minus cost of goods sold), operating margin (revenue minus COGS and operating expenses), and net margin (revenue minus all expenses including taxes and interest).
For gross margin, only include direct production costs such as materials and direct labor. For operating margin, add in overhead like rent, utilities, and salaries. For net margin, include everything—interest payments, taxes, and one-time charges. Each margin tells a different story about your business health.
Compare your margins to industry benchmarks to see where you stand. A restaurant might operate on 3–9% net margins, while a software company might see 20–30%. Tracking margins over time reveals whether your pricing strategy, cost controls, and operational efficiency are improving or declining.
Worked Example
Suppose your business earned $500,000 in revenue last year and your total costs (COGS, operating expenses, taxes, interest) were $425,000.
Net Profit = $500,000 − $425,000 = $75,000 Net Profit Margin = ($75,000 / $500,000) × 100 = 15%
This means you keep 15 cents of every dollar earned as profit. If your COGS alone was $300,000, your gross margin would be ($500,000 − $300,000) / $500,000 × 100 = 40%.
Why It Matters
Profit margin is one of the most important indicators of business health. A healthy margin means you can reinvest in growth, weather downturns, and pay yourself a reasonable salary. Lenders and investors scrutinize margins to assess risk. Declining margins are an early warning sign of pricing pressure, rising costs, or operational inefficiency that needs immediate attention.
Practical Tips
- ✓Track margins monthly rather than annually to catch negative trends early.
- ✓Benchmark against your specific industry—margins vary wildly between sectors.
- ✓Improve margins by negotiating supplier costs before raising prices on customers.
