Profitability tells you how much a business gets out of what it puts in. You don't just look at profit in euros. You set it in relation to a reference figure, for example revenue or the equity invested. This lets you see at a glance whether a business really operates efficiently.
The two most common measures are return on sales and return on equity. Return on sales shows how much of the revenue remains as profit. A small trade business generates 300,000 EUR in revenue and 36,000 EUR in profit: that is a 12 % return on sales. Return on equity relates the profit to the money the owner has put into the business.
When buying a small business, profitability often says more than raw profit. A business with a 12 % return on sales can be more attractive than a larger one with only 3 %, because it keeps far more per euro of revenue and copes better with fluctuations. That is why profitability is a central building block for the business valuation.
For you as a successor, one question matters: is profitability high enough for the purchase price and financing to be sustainable, with a fair owner's salary left over for you at the end? Profitability is closely tied to cash flow and EBITDA, because only a profitable business generates free funds over the long term.
Look at profitability over several years, not just one good snapshot. One-off effects or a particularly strong year can distort the picture. A business that is stably profitable year after year gives you more certainty than one with a single upward outlier.
For business sellers
If your business has been stably profitable for years, that is one of your strongest selling points. Back it up with clean figures for due diligence.
Strong profitability often justifies a higher price. It feeds directly into the business valuation and the price negotiation.
For corporate buyers
Check profitability over several years before you buy. This shows whether the business truly operates profitably or just had one good year.
Work out whether profitability is enough to cover the purchase price, acquisition financing and your owner's salary. The liquidity must hold up at all times.
Example
A small hair salon generates 240,000 EUR in revenue per year and makes 28,800 EUR in profit. That works out to a 12 % return on sales, a solid figure that lets a successor comfortably carry the purchase price and financing.
FAQ
What is the difference between profitability and profit?
Profit is an absolute amount in euros. Profitability sets it in relation to a reference figure such as revenue or equity. Only then can you fairly compare businesses of different sizes.
What profitability is good for a small business?
This depends heavily on the industry. For small service and trade businesses, returns on sales of around 8 to 15 % are often considered solid. More important than a rule of thumb is a figure that stays stable over several years.
How do I calculate return on sales?
You divide profit by revenue and multiply by 100. With 300,000 EUR in revenue and 36,000 EUR in profit, that is 12 %. This figure also feeds into EBITDA-based valuations.
Why is profitability so important when buying?
Only a profitable business earns enough to carry the purchase price and financing and still leave you a fair salary. It is closely tied to cash flow and is a core point of due diligence.
Does buying instead of founding pay off in terms of profitability?
Often yes: an existing business is usually already profitable and comes with customers, revenue and established routines. When founding, you first have to build that profitability over years, with an uncertain outcome.
Can a small business be more profitable than a large one?
Yes. A small business with a 12 % return on sales keeps more per euro of revenue than a larger one with 3 %. Size alone says nothing about profitability.
