What is net profit margin?
Net profit margin is the percentage of revenue a business keeps as profit after deducting all expenses, interest and taxes. It's often called the "bottom line" expressed as a percentage, giving you a clear picture of how much of each ringgit earned actually stays in your pocket.
This metric goes beyond surface-level figures. While revenue shows how much money comes in, net profit margin reveals what you truly retain. For small business owners, it's one of the most reliable ways to measure overall financial health, alongside other profitability ratios.

Net profit margin formula
Calculating your net profit margin is straightforward once you know your net profit and total revenue. The formula gives you a percentage that you can use to compare performance over time or against others in your industry.
Net profit margin = (net profit ÷ revenue) × 100
Net profit is your revenue minus cost of goods sold (COGS), operating expenses, interest and taxes.
How to calculate net profit margin
Follow these steps to work out your net profit margin. You'll need your total revenue and a breakdown of all your costs for the period, which you can pull together when you measure your profitability.
- Calculate your net profit by subtracting COGS, operating expenses, interest and taxes from your total revenue.
- Divide your net profit by your total revenue.
- Multiply the result by 100 to get your net profit margin as a percentage.
Example of a net profit margin calculation
Suppose you run a small office cleaning business in Malaysia. In one month, you earn RM20,000 in revenue from cleaning contracts. Your cost of goods sold (cleaning supplies, equipment) totals RM8,000, leaving you with a gross profit of RM12,000.
From that gross profit, you pay RM3,000 in operating expenses (wages, transport, utilities) and RM4,000 in taxes. Your net profit is RM12,000 − RM3,000 − RM4,000 = RM5,000.
To find your net profit margin, divide RM5,000 by RM20,000 and multiply by 100. That gives you a net profit margin of 25%. This means you keep 25 sen of every ringgit earned after covering all your costs.
What is a good net profit margin?
There's no single answer to what counts as a "good" net profit margin, but general benchmarks can help you gauge where you stand.
- Around 5% is considered low and may signal tight margins or high costs.
- Around 10% is average and suggests a healthy, sustainable business.
- 20% or more is strong and indicates solid profitability.
Keep in mind that acceptable margins vary widely by industry. A grocery retailer might operate on thin margins of 2–3%, while a consultancy could see margins above 20%. Compare your margin to businesses similar to yours, and to your wider profit margins, for a more meaningful picture.
Net profit margin vs gross and operating profit margin
Net profit margin is one of several profitability ratios. Understanding how it differs from gross and operating profit margin helps you see which costs are affecting your bottom line.
- Gross profit margin measures revenue minus cost of goods sold only. It shows how efficiently you produce or deliver your product or service.
- Operating profit margin measures revenue minus COGS and operating expenses, but before interest and taxes. It reflects the profitability of your core operations.
- Net profit margin measures revenue minus all expenses, including COGS, operating expenses, interest and taxes. It captures your true bottom-line profitability.
Of the three, net profit margin gives you the most complete view of how much profit your business actually keeps.
Why net profit margin matters
Your net profit margin is a window into your business's financial health. It tells you whether your pricing covers all your costs and leaves room for growth. Lenders and investors often look at this metric when assessing your business, so a healthy margin can open doors to funding.
Beyond external scrutiny, tracking your margin helps you make smarter decisions. If margins are shrinking, you know to review your expenses or revisit your pricing to increase your profits. A higher margin isn't automatically better, however. Aggressive cost-cutting can harm quality or growth. The key is to track your margin over time and compare it within your industry to spot trends and opportunities.
