Gross profit is turnover less cost of sales. Operating profit then deducts distribution and administrative costs and adds other operating income, before interest and tax. Net profit usually means the final profit or loss for the year after interest and tax. Gross profit tests pricing and buying, operating profit tests whether the trade covers its overheads, and net profit shows what is left for the owners, which is why lenders focus on the middle figure and owners on the last.

How is each profit measure calculated?

The statutory Format 1 profit and loss account in Schedule 1 to SI 2008/410 runs: turnover; cost of sales; gross profit or loss; distribution costs; administrative expenses; other operating income; investment income and interest receivable; amounts written off investments; interest payable and similar expenses; tax on profit or loss; profit or loss after taxation; and finally profit or loss for the financial year. The three common measures are cuts through that list.

Measure Calculation Statutory line
Gross profit Turnover less cost of sales Gross profit or loss
Operating profit Gross profit less distribution and administrative costs, plus other operating income No line of that name in Format 1
Profit before tax Operating profit plus investment income, less interest payable Not listed as an item, but paragraph 6 of Schedule 1 requires it to be shown
Net profit Profit after tax Profit or loss for the financial year

Gross profit depends heavily on what is classified as cost of sales. Format 2, which analyses costs by nature, has no gross profit line at all.

Is operating profit a required line?

Not for most UK companies at present. Format 1 has no operating profit line, and the FRC’s basis for conclusions to FRS 102 (paragraph B5.2) records that no mandatory requirement to disclose operating profit was included, though guidance was given for entities that choose to present it. The worked example in the appendix to Section 5 shows operating profit as a subtotal after other operating income and before interest, which is how most UK accounts that show it are laid out.

That is changing for some entities. The FRC’s February 2026 amendments to FRS 102 add paragraph 5A.4, which requires an entity that adapts the statutory formats to present an operating profit or loss line, along with a profit or loss before financing and taxation line. They apply for accounting periods beginning on or after 1 January 2027, with early application permitted. For groups reporting under IFRS, IFRS 18 paragraph 69 requires totals and subtotals for operating profit or loss, profit or loss before financing and income taxes, and profit or loss, for annual periods beginning on or after 1 January 2027. Our page on profit and loss formats covers adapted formats.

What does net profit actually mean?

The phrase is used loosely, and that causes real misunderstandings in loan applications and sale negotiations.

  • In a company’s accounts, the clearest meaning is the profit or loss for the financial year, after interest and corporation tax.
  • In ratio analysis, ACCA’s guidance notes that operating profit margin is sometimes known as net profit margin. Someone quoting a net margin may mean a figure before interest and tax.
  • For a sole trader or partnership, net profit is normally the profit before personal income tax and National Insurance, because those are the owner’s liabilities, not the business’s. Drawings are not deducted; see drawings for sole traders.

When a lender, buyer or adviser asks for net profit, confirm which line they mean before giving a figure.

What does a worked example look like?

Illustration only. A wholesale company has turnover of £1,200,000.

£ Margin
Turnover 1,200,000
Cost of sales (780,000)
Gross profit 420,000 35%
Distribution costs (90,000)
Administrative expenses (210,000)
Operating profit 120,000 10%
Interest payable (30,000)
Profit before tax 90,000 7.5%
Tax (illustrative) (20,000)
Profit for the financial year 70,000 5.8%

Using ACCA’s formulas, gross margin is gross profit divided by revenue (35%), operating profit margin is profit before interest and tax divided by revenue (10%), and interest cover is operating profit divided by finance costs (four times).

What does each measure tell an owner?

  • Gross profit shows whether prices cover the direct cost of what is sold. A falling gross margin points to discounting, supplier price rises, waste or theft. HMRC’s Enquiry Manual at EM3082 describes gross profit rate as the most commonly used business ratio in HMRC, so a margin out of line with the trade can also attract questions.
  • Operating profit shows whether the core trade pays for its overheads, regardless of how the business is financed. It is the fairest figure for comparing two businesses with different borrowing.
  • Net profit shows what has been earned for the owners after lenders and the tax authorities have been paid. For a company, it feeds retained earnings, but it is not the dividend limit. Section 830 of the Companies Act 2006 allows distributions only out of accumulated realised profits less accumulated realised losses, so a company with a profitable year can still be unable to pay a dividend if earlier losses have not been made good. See distributable reserves.

What do lenders look at?

Lenders care first about whether the trade generates enough profit to pay interest. ACCA’s guidance defines interest cover as operating profit divided by finance costs and says that anything in excess of three is usually considered safe; return on capital employed uses profit before interest and tax for the same reason. Bank covenants often use their own definitions, so the loan agreement wording overrides any textbook ratio.

Lenders also need to see the figures. Under section 444(1) of the Companies Act 2006 a company subject to the small companies regime must file a balance sheet but may choose whether to file its profit and loss account, so a lender usually asks for the full accounts or management accounts rather than relying on the public record. A small company with the consent of all its members may also abridge its profit and loss account under paragraph 1A(2) of Schedule 1 to SI 2008/409, combining turnover, cost of sales, gross profit and other operating income into a single gross profit or loss line.

How do these figures relate to taxable profit?

Tax starts from the accounts. Section 46 of the Corporation Tax Act 2009, and section 25 of the Income Tax (Trading and Other Income) Act 2005 for traders not on the cash basis, require trading profits to be calculated in accordance with generally accepted accounting practice, subject to any adjustment required or authorised by law. Profit before tax is therefore the starting point, with disallowable items added back and capital allowances claimed instead of depreciation. See corporation tax explained for how the tax is then charged.

What mistakes come up most often?

  • Confusing margin with markup. HMRC’s EM3503 sets out the conversion: gross profit rate equals markup divided by (markup plus 100), multiplied by 100. A 50% markup is a 33.3% margin.
  • Comparing gross margins across businesses that classify wages, delivery or depreciation differently.
  • Treating profit as cash. Stock build ups, slow paying customers and loan repayments absorb cash without touching profit.
  • Ignoring one off items. A property sale or a large bad debt can swamp operating profit; FRS 102 paragraph 5.9A requires material items to be disclosed separately.
