Subtract cost from selling price to get gross profit, then divide by selling price and multiply by 100. Formula: Margin = ((Selling Price - Cost) / Selling Price) x 100.

It varies by industry. Retail: 2-5%. Professional services: 15-30%. Tech: 20-40%. Net profit above 10% is generally considered healthy for most UK businesses.

Exclude VAT. It is collected for HMRC and is not your income. Always work with ex-VAT selling prices for accurate margin calculations.

Divide the markup percentage by (1 + markup as a decimal) and multiply by 100. A 50% markup = 50 / 1.50 x 100 = 33.3% margin.

Understanding Margin vs Markup

Profit margin and markup are related but different calculations that are frequently confused. Margin is the profit as a percentage of the selling price, while markup is the profit as a percentage of the cost price. If you buy an item for 50 pounds and sell it for 100 pounds, your profit is 50 pounds. The margin is 50 per cent (50 divided by 100), while the markup is 100 per cent (50 divided by 50). The same profit expressed as margin is always a smaller number than expressed as markup.

Gross profit margin considers only the direct cost of goods sold, while net profit margin deducts all business expenses including overheads, salaries, rent, marketing and taxes. A business might have a healthy gross margin of 60 per cent but a net margin of only 10 per cent after all operating costs. Tracking both metrics separately helps you identify whether profitability issues stem from pricing and cost of goods or from excessive overhead expenses.

What Is a Good Profit Margin?

Healthy profit margins vary enormously by industry. Retail businesses typically operate on net margins of 2 to 5 per cent, relying on high volume to generate absolute profit. Service businesses and consultancies often achieve net margins of 15 to 25 per cent because they have lower cost of goods. Software companies can achieve margins of 20 to 40 per cent or more due to the scalability of digital products. Food and hospitality businesses often work on thin margins of 3 to 9 per cent, which is why cost control is so critical in these sectors.

Comparing your margins with industry averages helps you assess your competitive position. If your margins are significantly below average, it may indicate pricing that is too low, costs that are too high or operational inefficiencies. If your margins are well above average, you may have a competitive advantage worth protecting, or there may be room to invest in growth by accepting a temporarily lower margin to gain market share.

Improving Your Profit Margins

There are fundamentally two ways to improve margins: increase revenue or reduce costs. On the revenue side, strategies include raising prices, upselling higher-margin products, bundling products to increase average order value and improving conversion rates. On the cost side, negotiating better supplier terms, reducing waste, automating processes and reviewing overhead expenses all contribute to better margins. The most effective approach usually combines elements of both.
