How to Calculate Your Business Profit Margin (And What It Should Be)
Revenue is vanity. Profit is sanity. You've probably heard some version of that before. But it's one of those clichés that's a cliché because it's true.
A business doing $50K/month in revenue with 10% margins takes home $5K. A business doing $20K/month with 40% margins takes home $8K. The second business makes 60% more money despite doing less than half the revenue.
If you don't know your profit margin, you don't know your business. Here's how to calculate it.
Gross Margin vs. Net Margin
There are two types of profit margin that matter for small businesses, and they tell you different things.
Gross profit margin measures how much you keep after the direct costs of delivering your product or service. If you sell candles, this is revenue minus the cost of wax, wicks, jars, labels, and packaging. If you're a consultant, this is revenue minus any direct delivery costs (subcontractors, tools specific to the project).
The formula: (Revenue - Cost of Goods Sold) / Revenue × 100
If you did $20,000 in revenue last month and your direct costs were $8,000, your gross margin is ($20,000 - $8,000) / $20,000 × 100 = 60%.
Net profit margin is what you keep after everything — direct costs, rent, salaries, software, insurance, marketing, taxes, all of it.
The formula: (Revenue - All Expenses) / Revenue × 100
If that same $20,000 in revenue had $8,000 in direct costs plus $7,000 in operating expenses (rent, marketing, software, etc.), your net margin is ($20,000 - $15,000) / $20,000 × 100 = 25%.
Gross margin tells you if your product is priced right. Net margin tells you if your business is run efficiently.
What "Healthy" Looks Like by Business Type
Healthy margins vary wildly by industry. A grocery store with 3% net margins can be perfectly healthy while a SaaS company at 3% is in trouble. Here are rough benchmarks:
Service businesses (consulting, agencies, freelancing): Gross margins of 50-80% are typical since your primary cost is your time. Net margins of 20-40% are healthy.
E-commerce and retail: Gross margins of 30-60% depending on the product. Net margins of 10-20% after shipping, returns, marketing, and platform fees.
Food and beverage: Gross margins of 60-70% on the food itself, but after labor, rent, and waste, net margins of 5-15% are considered good.
SaaS and digital products: Gross margins of 70-90% since the cost of serving one more customer is nearly zero. Net margins of 20-40% are strong.
Manufacturing: Gross margins of 25-45%. Net margins of 5-15% are typical.
If your margins are significantly below these ranges for your industry, that's a signal worth investigating.
How to Calculate Yours in 5 Minutes
You don't need accounting software to get a rough number. Here's the quick approach:
Pull up your bank statement from last month. Add up all the money that came in — that's your revenue. Now go through the expenses. Separate them into two groups: costs directly tied to delivering your product (cost of goods sold) and everything else (operating expenses).
Revenue minus cost of goods sold, divided by revenue, times 100. That's your gross margin.
Revenue minus all expenses, divided by revenue, times 100. That's your net margin.
Even a rough calculation puts you ahead of most business owners who never calculate it at all.
Four Ways to Improve Your Margins
If your margins are lower than you'd like, there are really only four levers:
Raise prices. This is the fastest and most underused lever. Most small businesses undercharge. A 10% price increase on a product with 50% margins increases your profit by 20%. Test it. Most businesses lose fewer customers than they expect.
Reduce direct costs. Negotiate with suppliers. Find alternative materials. Reduce waste. Even a 5% reduction in COGS drops straight to your bottom line.
Cut operating expenses. Audit every subscription and recurring cost. Cancel what you're not using. Renegotiate contracts. Switch to more cost-effective tools. Most businesses are paying for at least 2-3 things they forgot they signed up for.
Increase volume without increasing fixed costs. This is the growth play — if your fixed costs stay the same while revenue grows, margins improve automatically. Digital products, subscriptions, and automated services scale this way.
Why Margins Matter More Than Revenue
A business with great margins and modest revenue has options. They can invest in growth when they're ready. They can survive downturns. They can pay themselves well.
A business with high revenue and thin margins is fragile. One bad month, one supplier price increase, one algorithm change on their marketing channel, and they're in crisis.
Margins are resilience. Revenue is just activity.
