Gross Profit vs Net Profit

Both metrics matter, yet they serve distinct purposes. A business can post impressive gross profit while losing money overall. Conversely, tight control over operating costs can transform modest gross profit into healthy net earnings. This guide breaks down both concepts, explains the formulas and shows how to use these figures when assessing a company’s financial health.

This information is educational and does not constitute financial, tax or accounting advice. Profitability metrics are just one factor among many when analysing businesses.

What is gross profit?

Gross profit measures what remains from revenue after subtracting the direct costs of producing goods or delivering services. These direct costs are called cost of goods sold, or COGS. For a manufacturer, COGS includes raw materials, factory labour and production overheads directly tied to making products. For a retailer, it typically means the wholesale price paid for inventory.

The gross profit meaning centres on production efficiency. It answers a simple question: how much does the company keep from each sale before paying for anything else?

Gross profit excludes operating expenses such as rent, marketing, administrative salaries and interest on loans. It also excludes tax. Think of it as the profit generated specifically from the core activity of making or buying what the business sells.

Gross profit formula

The gross profit formula is straightforward:

Gross Profit = Revenue - Cost of Goods Sold

Revenue refers to total sales income before any deductions. Cost of goods sold covers only those expenses directly attributable to production or procurement.

For example, if a furniture manufacturer generates £500,000 in annual sales and spends £300,000 on timber, hardware and factory wages, the gross profit is £200,000.

What does gross profit tell you?

Gross profit reveals how efficiently a company converts raw inputs into sellable products. A rising gross profit suggests the business is either increasing prices, reducing production costs or selling more units. A falling gross profit may signal problems: rising supplier costs, pricing pressure from competitors or production inefficiencies.

This figure is particularly useful for comparing companies within the same industry. Two retailers might generate identical revenue, but the one with lower purchasing costs or better supplier agreements will show higher gross profit. That difference matters when assessing competitive positioning.

However, gross profit tells you nothing about whether the business is actually profitable overall. A company might have excellent gross profit but spend so heavily on marketing, administration or debt interest that it still loses money.

What is net profit?

Net profit represents what remains after subtracting all expenses from revenue. This includes the cost of goods sold, operating expenses, interest payments and taxes. It is the bottom line, the final profit figure that shows whether the business made or lost money during the period.

When people ask what is net profit, they are essentially asking: what did the company actually earn after everything was paid?

Net profit flows to shareholders. It can be distributed as dividends, reinvested in the business or held as retained earnings. This figure determines the real financial outcome of all business activities combined.

Net profit formula

The net profit formula accounts for all costs:

Net Profit = Revenue - Cost of Goods Sold - Operating Expenses - Interest - Taxes

Alternatively, starting from gross profit:

Net Profit = Gross Profit - Operating Expenses - Interest - Taxes

Operating expenses include salaries for non-production staff, rent, utilities, marketing, insurance, depreciation and general administrative costs. Interest covers payments on loans and other debt. Taxes represent corporation tax or equivalent levies on profits.

Is net profit after tax?

Yes, net profit is calculated after tax. This is a common point of confusion. The figure reported as net profit, net income or the bottom line on an income statement reflects earnings after the company has accounted for its tax liability.

Some financial analysis uses pre-tax profit, also called profit before tax or PBT, for comparisons across jurisdictions with different tax rates. However, the standard definition of net profit includes tax as a deduction. When reviewing UK company accounts, the net profit figure will have corporation tax already subtracted.

Key differences between gross profit and net profit

The distinction between these two metrics lies in what costs they include. Gross profit considers only direct production costs. Net profit considers everything.

A company with high gross profit but low net profit is spending heavily on areas outside production. This might indicate large marketing investments, high administrative costs, significant debt burdens or all three. Conversely, a company with modest gross profit but reasonable net profit has found ways to keep other costs low.

Neither situation is inherently good or bad. A fast-growing technology company might deliberately sacrifice net profit to fund customer acquisition. A mature manufacturer might prioritise net profit stability over growth. Context matters enormously when interpreting these figures.

Gross profit margin vs net profit margin

Absolute profit figures tell only part of the story. A company earning £1m net profit sounds impressive until you learn it generated £500m in revenue. Profit margins express profits as percentages of revenue, enabling meaningful comparisons regardless of company size.

Gross profit margin shows what percentage of revenue remains after direct production costs. Net profit margin shows what percentage of revenue becomes actual profit after all expenses.

How to calculate profit margins

The formulas convert absolute figures into percentages:

Gross Profit Margin = (Gross Profit ÷ Revenue) × 100

Net Profit Margin = (Net Profit ÷ Revenue) × 100

Using earlier numbers: if revenue is £500,000 and gross profit is £200,000, the gross profit margin is 40%. If net profit after all expenses is £50,000, the net profit margin is 10%.

These percentages reveal efficiency at different levels. A 40% gross profit margin means the company keeps £0.40 from every pound of sales after paying for what it sells. A 10% net profit margin means £0.10 from every pound eventually becomes profit.

Margins vary dramatically across industries. Supermarkets operate on thin margins, sometimes below 5% net profit margin, but compensate through enormous sales volumes. Software companies might achieve net margins above 20% because their products cost little to reproduce once developed. Comparing margins across different industries rarely produces useful insights.

Why both metrics matter for evaluating a business

Examining gross profit and net profit together provides a fuller picture of business performance. Each metric answers different questions, and both are necessary for thorough analysis.

Gross profit reveals:

• Whether the core business model works

• How pricing compares to production costs

• Vulnerability to supplier cost increases

• Competitive positioning on cost efficiency

Net profit reveals:

• Whether the company makes money overall

• How well it controls all expenses, not just production costs

• The true return generated from operations

• Sustainability of the business model

A company might have strong gross profit but weak net profit if it overspends on marketing, carries excessive debt or maintains bloated administrative functions. Alternatively, a business might have modest gross profit but healthy net profit through exceptional cost discipline elsewhere.

Trends matter as much as current figures. A shrinking gross profit margin might indicate rising supplier costs or pricing pressure. A widening gap between gross and net profit margins might suggest operating expenses are growing faster than revenue.

It is worth noting that profitability metrics alone do not predict future performance. Past profits do not guarantee future profits. These figures should be considered alongside other factors including cash flow, debt levels, competitive dynamics and broader economic conditions.

Gross profit vs operating profit: A quick comparison

Operating profit sits between gross profit and net profit on the income statement. It represents earnings after deducting cost of goods sold and operating expenses, but before subtracting interest and tax.

Operating profit isolates the profitability of core business operations. It excludes financing decisions, since interest depends on how much debt the company carries, and excludes tax, which varies by jurisdiction and can fluctuate based on allowances and reliefs.

Operating profit is useful for comparing companies with different capital structures or in different tax jurisdictions. Two otherwise identical businesses might show different net profits purely because one carries more debt or operates somewhere with higher corporation tax. Operating profit strips out these differences.

The term EBIT, meaning earnings before interest and tax, is often used interchangeably with operating profit, though technical definitions can vary slightly depending on accounting standards.

Practical example: Gross vs net profit in action

Consider a fictional UK-based online retailer, Homecraft Ltd, selling home furnishings. Here are simplified figures for one financial year:

Revenue: £2,000,000

Cost of goods sold: £1,200,000

Gross profit: £800,000

Operating expenses breakdown:

• Staff salaries: £250,000

• Marketing: £150,000

• Rent and utilities: £80,000

• Administrative costs: £70,000

• Depreciation: £30,000

Total operating expenses: £580,000

Operating profit: £220,000

Interest on business loan: £20,000

Profit before tax: £200,000

Corporation tax: £50,000

Net profit: £150,000

Calculating the margins:

Gross profit margin: (£800,000 ÷ £2,000,000) × 100 = 40%

Net profit margin: (£150,000 ÷ £2,000,000) × 100 = 7.5%

What does this tell us? Homecraft keeps 40p from every pound after paying suppliers, a reasonable margin for retail. However, substantial operating costs, particularly staff and marketing, consume most of that gross profit. The final 7.5% net margin is modest but positive.

If Homecraft wanted to improve net profit, it could pursue several paths: negotiate better supplier terms to increase gross profit, reduce marketing spend, find cheaper premises or pay down debt to lower interest costs. Each lever affects different profit levels.

Summary

Gross profit and net profit serve as complementary measures of business performance. Gross profit reveals how efficiently a company produces or sources what it sells, calculated by subtracting cost of goods sold from revenue. Net profit shows what remains after every expense, including operating costs, interest and tax.

The key differences are summarised below:

Profit margins express these figures as percentages of revenue, enabling comparisons across companies of different sizes. Both gross profit margin and net profit margin provide useful benchmarks, though they vary significantly across industries.

Understanding both metrics helps paint a complete picture of financial health. A business needs healthy gross profit to demonstrate its core model works, and it needs positive net profit to sustain operations over time. Examining trends in both figures reveals more than looking at either in isolation.

Remember that profitability metrics represent one element of financial analysis. They should be considered alongside cash flow, balance sheet strength, competitive factors and broader market conditions when forming views about any business.
