What Is a Good Profit Margin?

What counts as a good margin?

For most UK trading businesses, a net profit margin between 5% and 15% is healthy. On the gross side, the practical test is whether it clears your overhead percentage with room left over. Anything more precise depends on which margin you mean and what you sell.

That last part does most of the work. A 20% margin is excellent as a net figure, unremarkable as a gross figure in wholesale, and alarming as a gross figure in a clothing shop. Before you hold your number against anybody else's, check you are both talking about the same line of the accounts. Our gross profit and net profit comparison sorts out which is which.

The benchmark that actually helps is internal. Divide your monthly overheads by your monthly sales. That percentage is the gross margin you have to beat before any profit exists at all. A business with £8,000 of overheads on £30,000 of turnover needs to clear 27% before it earns a penny, and a 30% gross margin suddenly looks a lot less comfortable than it sounded.

Does business size change the answer?

It changes the shape more than the level, and three patterns come up again and again.

Very small businesses often report a net margin that looks better than it is, because the owner takes dividends rather than a salary. Put a market rate for the owner's time back in and the figure frequently halves. Comparing a one-person consultancy against a company with a payroll is comparing two accounting conventions, not two businesses.

Growing businesses usually watch net margin fall before it rises. The first hire, the first premises, the first proper system all land as overhead before the volume turns up to absorb them. A dip during expansion is normal. A dip while sales sit flat is not.

Larger businesses trade margin for volume on purpose. Buying power drops the cost, competition hands most of that saving to the customer, and the model works because the same pound of overhead is spread across an enormous number of transactions. Grocery runs on 1% to 3% net and nobody there considers that a problem.

How should you judge your own figure?

Is it moving? Direction beats level every time. Margin sliding while revenue climbs means you are buying growth, and that only ends well if the fall was deliberate and has a date on it.

Does it survive a shock? A 4% net margin gets wiped out by a 4% cost rise you cannot pass on. Work out what your figure absorbs before it goes negative, then decide whether you are comfortable.

Is the mix hiding something? A stable blended margin can conceal one product collapsing while another improves. Check your biggest few lines on their own with the profit margin calculator.

And is it real? Margins worked out on gross prices, on ticket prices instead of paid prices, or on costs missing carriage are all fiction, and flattering fiction at that. How to calculate profit margin goes through each of those corrections.
