If you only have time to look at one profit number, look at this one. Net profit is what's left after the business has paid for everything - the materials, the team, the rent, the software, the marketing, the interest on debt, and the taxes. Whatever's left is what the business actually made.
Net profit - revenue minus all costs, including the cost of producing what you sold, operating expenses, interest payments, and taxes. The final "bottom line" on a profit and loss statement.
Net profit = Revenue − COGS − Operating expenses − Interest − Taxes Net margin = Net profit ÷ Revenue × 100%
The three profit numbers, top to bottom
A profit and loss statement (P&L) doesn't show just one profit - it shows three, stacked from top to bottom. Each one strips out a different layer of cost. Net profit is what's left after every layer.
- Revenue (top of the page)
- − Cost of Goods Sold (direct costs)
- = Gross profit
- − Operating expenses (rent, salaries not in COGS, marketing, software, insurance, etc.)
- = Operating profit
- − Interest on debt
- − Taxes
- = Net profit (bottom of the page)
Each level answers a different question. Gross profit asks "does the product or service make money?" Operating profit asks "does the business make money?" Net profit asks "does the whole package - business, financing, taxes - make money?"
Why net profit deserves your closest attention
Net profit is the only profit number that fully accounts for the whole business. The earlier numbers - gross, operating - tell you about pieces. Net tells you about the whole.
It's what reinvests in the business.The profit you keep is what funds next year's growth, pays down debt, builds cash reserves, or distributes to owners. Operating profit doesn't do any of that until interest and taxes are paid; net profit does.
It's what buyers value.If you ever sell the business, the buyer's offer will be a multiple of profit - usually net profit or a normalized version of it. Revenue gets a smaller multiple than profit. Owners optimizing for sale value should optimize for profit growth, not pure revenue growth.
It's the bottom line.When the bank asks "is this business profitable," they mean net profit. When an investor asks "what's your margin," they usually mean net margin. The single number that gets most reported and most compared is this one.
What "good" net margin looks like
Like gross margin, net margin is meaningful relative to your industry, not in absolute terms. Rough small-business ranges:
- Software / SaaS: 10-25% (higher for established, lower while growing fast)
- Professional services / consulting: 10-20%
- Agencies and creative services: 8-15%
- Manufacturing: 5-15%
- E-commerce: 5-15%
- Restaurants: 3-6%
- Retail (general): 2-6%
- Construction / contractors: 5-10%
Small businesses across most categories land somewhere between 5% and 20%. Above 25% net margin tends to mean software, intellectual property, or a strong moat. Below 5% means high volume, thin margins, and very little room for error.
Net profit is not cash
The single most important caveat about net profit: it's not the same as the cash in your bank account. A business can report strong net profit and still run out of cash. Three reasons:
Timing. Revenue is recognized when a sale happens; cash arrives when the customer pays. A business sending out $50K of invoices on 60-day terms shows the revenue today, but the cash is two months away.
Non-cash expenses.Depreciation lowers net profit but doesn't actually move cash. The cash for the equipment left the business when it was bought; depreciation just allocates that historical cost over future periods.
Investment and financing. Buying inventory, paying down loan principal, and investing in equipment all consume cash without touching the profit number.

Worked example: same revenue, different net profit
Two service businesses with identical revenue, very different bottom lines.
Agency A - thin overhead, healthy margin
- Revenue: $200,000
- COGS (contractors): $90,000 → Gross profit $110,000 (55%)
- Operating expenses: $70,000
- Interest + taxes: $8,000
- Net profit: $32,000 (16% net margin)
Agency B - bloated overhead
- Revenue: $200,000
- COGS (contractors): $90,000 → Gross profit $110,000 (55%)
- Operating expenses: $98,000 (larger office, more software, more SDRs)
- Interest + taxes: $8,000
- Net profit: $4,000 (2% net margin)
Identical revenue. Identical gross margin. Eight times the net profit at Agency A - because the overhead is leaner. Owners chasing growth often grow operating expenses faster than revenue and end up with Agency B's P&L without noticing.
Common mistakes business owners make
1. Treating net profit as cash
The most expensive mistake. Reinvesting or paying out based on the P&L without checking the bank account leads to avoidable cash crunches. Always reconcile.
2. Comparing your net margin to a competitor's gross margin
"They're at 60% margin and we're at 10%" is meaningless if they're quoting gross and you're quoting net. Make sure both numbers are the same metric.
3. Ignoring owner compensation
Some owners don't pay themselves a market salary and treat the gap as net profit. The business looks more profitable than it is. If you replaced yourself with a hired operator, what would the actual net profit be? That's the honest number.
4. Optimizing for net profit at the cost of growth
Especially common in mature businesses. Cutting every cost that doesn't produce profit this quarter starves tomorrow's growth. Net profit is a result, not the only input. Balance it against reinvestment.
