Profit is the goal of every business, but the word is imprecise on its own. Gross profit, operating profit, and net profit measure different things and tell different stories about your business. Knowing which number to use, and how to calculate it, is essential for making good decisions.

What Is Profit?
Profit is the financial gain remaining after costs are subtracted from revenue. But "costs" means different things depending on which profit measure you are calculating:
- Gross profit subtracts only the direct costs of producing your product or service
- Operating profit also subtracts operating expenses (rent, salaries, marketing)
- Net profit subtracts everything, operating costs, interest, and taxes
Each layer gives you different information about where your business is performing or leaking.
How Do You Calculate Gross Profit?
Formula: Gross Profit = Revenue − Cost of Goods Sold (COGS)
Gross Profit Margin % = (Gross Profit ÷ Revenue) × 100
COGS includes the direct costs of producing what you sell:
- For product businesses: materials, manufacturing labour, packaging, freight
- For service businesses: direct labour (staff time on billable work), subcontractors, direct tools
- NOT included: rent, office staff salaries, marketing, admin
Worked example:
A e-commerce business sells £200,000 of goods in a quarter. The products cost £80,000 to buy and ship to customers.
- Revenue: £200,000
- COGS: £80,000
- Gross Profit = £200,000 − £80,000 = £120,000
- Gross Margin = £120,000 ÷ £200,000 × 100 = 60%
Gross profit tells you how efficiently you turn revenue into value above direct costs. It answers: is the core business model viable?

How Do You Calculate Net Profit?
Formula: Net Profit = Revenue − COGS − Operating Expenses − Interest − Taxes
Net Profit Margin % = (Net Profit ÷ Revenue) × 100
Continuing the worked example above:
- Gross Profit: £120,000
- Operating expenses (rent, staff, marketing, software): £85,000
- Operating Profit (EBIT): £35,000
- Interest on business loan: £3,000
- Tax: £7,000
- Net Profit = £35,000 − £3,000 − £7,000 = £25,000
- Net Margin = £25,000 ÷ £200,000 × 100 = 12.5%
Net profit is the "bottom line", the actual money the business generated after all costs. It is what investors and lenders focus on.
What Is the Difference Between Gross and Net Profit?
Gross profit shows production efficiency; net profit shows overall business health.
A business can have strong gross profit but poor net profit if overheads are high. This is common in businesses that scale revenue without managing operating costs, high staff headcount, expensive office space, or heavy marketing spend can erode a healthy gross margin down to a thin or negative net margin.
Example comparison:
| Company A | Company B | |
|---|---|---|
| Revenue | £500,000 | £500,000 |
| Gross Margin | 70% (£350,000) | 40% (£200,000) |
| Operating Costs | £320,000 | £150,000 |
| Net Profit | £30,000 (6%) | £50,000 (10%) |
Company A has a much higher gross margin, its product economics are stronger. But Company B has lower operating costs and actually generates more net profit. Both metrics matter.
What Is Operating Profit?
Formula: Operating Profit = Gross Profit − Operating Expenses
Also called EBIT (Earnings Before Interest and Taxes), operating profit measures the profit generated by core business operations, before the effect of financing decisions (interest) and tax.
This is the number that tells you: if we removed the debt and the tax, is this a profitable operation?
Operating profit is particularly useful when comparing businesses across different capital structures or tax jurisdictions, since it strips out those variables.
What Is a Good Profit Margin?
Margins vary enormously by industry. Here are benchmarks:
| Sector | Typical Gross Margin | Typical Net Margin |
|---|---|---|
| SaaS / Software | 70–85% | 15–30%+ |
| Professional services | 40–70% | 15–30% |
| E-commerce (branded) | 40–60% | 5–15% |
| Manufacturing | 25–40% | 5–15% |
| Retail | 30–50% | 2–8% |
| Hospitality / F&B | 60–75%* | 3–9% |
| Grocery / FMCG | 15–25% | 1–5% |
*Hospitality gross margin is high because COGS is only food/drink cost. After wages (the largest cost), net margin is thin.
If your gross margin is below the industry average, the problem is pricing or production costs. If your net margin is below average despite good gross margin, the problem is operating cost control.
How Do You Improve Your Profit Margin?
On gross margin:
- Raise prices, even a 5% increase on stable volume directly improves gross margin
- Reduce COGS, negotiate supplier costs, reduce waste, improve processes
- Shift product mix towards higher-margin products
On net margin:
- Cut operating costs that do not generate proportional return (excess staff, underused software, unnecessary premises)
- Improve revenue per employee, a key indicator of operating efficiency
- Grow revenue without proportionally growing fixed costs (leverage)

Common Profit Calculation Mistakes
Confusing revenue with profit. Revenue is the total income before any costs. Profit is what remains after costs. A business with £1 million revenue and £1.1 million costs is losing money.
Excluding owner salary from costs. Many small business owners do not pay themselves a market salary, which inflates apparent profit. If you replaced yourself with an employee, what would they cost? Include this in your true profit calculation.
Using gross margin to assess overall health. A 70% gross margin sounds impressive, but if operating costs consume 68% of revenue, net margin is only 2%.
Not tracking COGS separately from operating costs. This makes it impossible to calculate gross margin, which is essential for pricing decisions.
Frequently Asked Questions
What is the profit formula? Net Profit = Revenue − COGS − Operating Expenses − Interest − Taxes. Gross Profit = Revenue − COGS. Operating Profit = Gross Profit − Operating Expenses.
Can a business be profitable but cash flow negative? Yes, and this is a common small business problem. You can show a profit on a P&L statement but have no cash in the bank if customers have not paid yet (accounts receivable) or you have invested in inventory or equipment. Profit and cash flow are different measures.
What is the difference between profit and margin? Profit is an absolute number (£25,000). Margin is a percentage (12.5%). Both are useful, profit tells you the absolute gain, margin tells you the efficiency relative to revenue and allows comparison across businesses of different sizes.
How do you calculate markup from margin? Markup uses cost as the base; margin uses revenue. To convert: Markup = Margin ÷ (1 − Margin). Use our Markup Margin Calculator to convert between the two instantly.
Is profit the same as earnings? In financial reporting, earnings typically refers to net profit (the "bottom line"). EBITDA (Earnings Before Interest, Taxes, Depreciation and Amortisation) is a commonly used proxy for operating cash flow and is frequently used in business valuations.
