About profit margin

How the profit margin works

Gross profit is turnover less cost of sales, both entered without VAT (output VAT is owed to HMRC, never part of turnover). Gross margin is gross profit as a share of turnover; markup is gross profit as a share of cost — the same pounds, two denominators. Net profit takes overheads off gross profit and the net margin is that share of turnover. The after-tax line applies the Corporation Tax rate you enter: 19% at the small profits rate below £50,000 of profit, 25% at the main rate above £250,000, and an effective rate in between under marginal relief. A sector benchmark for the UK comes from the ONS Annual Business Survey and trade bodies rather than a single tax-office table.

Formula: Gross profit = revenue − COGS · margin = GP ÷ revenue · markup = GP ÷ COGS · net = GP − OpEx · after tax = net × (1 − rate)

UK Profit Margin Notes

UK margin checks often need to separate VAT from usable revenue, then include stock, delivery, payroll, National Insurance, rent, software, and card fees.

Use this version to compare markup, gross margin, and net margin before changing prices, supplier terms, or staffing levels.

UK-specific treatment for profit margin: figures are framed in pounds, with British household or business wording and the assumptions commonly seen in PAYE, HMRC, mortgage, pension, and consumer-credit contexts.

Watch for UK markers in the page copy and inputs: HMRC, PAYE, National Insurance, pension contributions, stamp duty land tax, miles, APR, part-exchange, council tax, VAT, and GBP-based totals.

The result should be read as a United Kingdom estimate, so compare it with UK provider quotes, HMRC or GOV.UK guidance, lender affordability rules, devolved-nation differences, or regulated advice where needed.

Gross margin = (Revenue − COGS) ÷ Revenue. Net margin includes all costs and tax.

What it is not

Not professional financial advice, not a guarantee of any specific outcome, and not a substitute for qualified advice for significant decisions.

Accuracy

All calculations run entirely in your browser using standard formulas. The calculator code does not submit your figures to GlobalCalc to obtain a result.

The inputs that most influence this result are shown in the breakdown above. Even small changes to key variables can have a significant compound effect over time.

Time is the most powerful variable

Longer periods amplify both growth and cost. Starting one year earlier or later can change a financial outcome by more than you expect.

Rate sensitivity

Even a 1% change in rate can materially change the outcome over a long period. Use Standard or Advanced mode to model rate sensitivity.

Compound effects

Most financial variables have a non-linear relationship with the result — they compound. The sensitivity table in Advanced mode shows this clearly.

To improve this result, focus on the inputs with the highest leverage. Small changes to the right variable often produce much larger outcomes than large changes to less important ones.

Find the binding constraint

Adjust inputs one at a time. The one that moves the result most is your binding constraint — focus effort there first.

Compare scenarios

Use the Scenario A/B feature in Advanced mode to compare two situations side by side.

Time your actions

Many financial decisions benefit from timing. Starting earlier, fixing a rate at the right moment, or clearing a debt before applying for new credit can each produce significant improvements.

Depending on what you are planning, these are the natural next steps after reviewing this result.

How gross margin, net margin, and EBITDA are calculated

The three profit margin types

Gross margin = (Revenue − COGS) ÷ Revenue × 100. Net margin = Net profit ÷ Revenue × 100. EBITDA margin = EBITDA ÷ Revenue × 100. Each measures profitability at a different stage of the income statement.

Margin typeWhat it excludesWhat it measures
Gross marginCOGS onlyCore production profitability
Operating marginCOGS + operating expensesBusiness efficiency before finance

UK profit margin checks by sector

UK margin work should separate VAT from usable revenue, then compare gross margin, operating margin, and net margin against the economics of the specific sector. A cafe, consultancy, trades business, SaaS company, and online retailer can all be healthy at very different percentages.

For UK decisions, a strong gross margin is only useful if it survives VAT handling, payroll, rent reviews, card fees, finance costs, and corporation tax. Use the calculator to model pounds kept per sale, not just the headline percentage.
