What is Gross Profit Margin?

Gross margin isolates the economics of the product or service itself from the cost of running the business around it. A 60% gross margin means that for every euro of sales, sixty cents survives to cover rent, wages, marketing, and interest — and whatever is left after all of those becomes net profit. Because it strips out overhead, gross margin is the cleanest point of comparison between two companies in the same industry: if one retailer earns 45% and another 30% on the same products, the difference is pricing power, supplier terms, or inventory efficiency.

What counts as a "good" gross margin depends entirely on the industry. Software and services businesses routinely run 70–90% because their direct costs are low; grocery retailers operate on 20–30% because volume and turnover make up for thin margins; manufacturers sit in between. The number to watch is not the absolute level but the trend — a gross margin that is falling period over period signals that input costs are rising faster than prices, discounting is eroding the price list, or the product mix is shifting toward lower-margin lines, and any one of those deserves investigation before it compounds.
