Take a look at your thumb. Now compare your thumb to another person’s thumb. There are differences in size, shape, manicure, strength, and flexibility between these two thumbs. Remember this comparison, as we will come back to it at the end of this article.
A Rule of Thumb is a brief measurement, typically based on a specific part of the operations of a business, such as revenues or some other easily calculated income stream, including Earnings Before Interest, Taxes, Depreciation and Amortization (EBITDA). The application of a rule of thumb includes some basic math, usually multiplying the selected source of income by a range of numbers.
Each industry, or type of business, usually has three or more different valuation rules of thumb that could potentially be applied to it. This means there are literally thousands of different rules of thumb that are available to provide indications of value for different types of businesses.
My favorite source of valuation rules of thumb is the Business Reference Guide, compiled by Tom West and published by Business Brokerage Press. This book is updated every year and includes over 800 pages of descriptions of different types of businesses and franchises, and the various valuation rules of thumb that industry experts have used over the years.
Take Dental Practices for an example. These types of practices are bought and sold fairly often. In the 2018 Business Reference Guide, the rules of thumb for Dental Practices are as follows:
- 60 to 70 percent of annual sales, including inventory
- 1.3 to 2.5 times Seller’s Discretionary Earnings (SDE), including inventory
- Three to four times Earnings Before Interest and Taxes (EBIT)
- Two to four times Earnings Before Interest, Taxes, Depreciation and Amortization (EBITDA)
- 50 to 70 percent of annual collections, depending on percentage of managed care versus private fee for service (cash), and the condition of equipment
Note the last rule of thumb listed. It illustrates an important point. Imagine a practice with $1,000,000 of annual collected revenues. According to that rule of thumb, the practice could sell for between $500,000 and $700,000. That’s a potential swing in value of $200,000. Often, the results of the other rules of thumb, measuring income streams such as SDE, EBIT, and EBITDA, will provide an even wider swing in potential values.
Now remember the two thumbs you were looking at earlier. The differences between your thumb and a potential buyer’s thumb can be quite significant, and generally speaking, no one knows what those differences will be until the two start comparing notes. It gets even more interesting if, instead of a potential buyer, the other thumb belongs to the Internal Revenue Service, or the out spouse in a divorce, or even a partner who wants to be bought out.
When valuing a privately held business, or even a part ownership interest in a privately held business, there are many options to consider. Rules of thumb are very useful. They can provide a range of potential values. But when it gets right down to it, most of the time a more specific, and supportable number is needed.
