How it's calculated
Gross profit = Revenue − COGS. The direct profitability of your products or services.
Operating profit / Net profit before tax = Gross profit − Operating expenses + Other income.
Corporation tax is estimated using 2026/27 UK rates: 19% on profits up to £50,000, 25% on profits over £250,000, with marginal relief between.
Margin = profit / revenue × 100. Gross margin uses gross profit; net margin uses net profit after tax.
Frequently asked questions
Anything above 10% net margin is healthy for most small businesses; varies hugely by industry.
Gross = revenue minus COGS. Net = after all operating expenses and tax.
Raise prices, lower COGS, cut unnecessary operating expenses. Most businesses find 5-10% with a systematic review.
