How to Read a Business Valuation Multiple by Industry
A multiple is a summary statistic from real sales, not a formula: why they vary so widely by industry, what the reporting window and main-street segment note actually mean, and why the published average is a starting point, not your business's price.
What a multiple actually is
A valuation multiple is not a formula — it’s a summary statistic. Ours is BizBuySell’s average of sale price ÷ reported SDE across real completed transactions in an industry. When a multiple reads 2.18×, it means businesses in that industry sold, on average, for about 2.18 times their SDE over the measured period — not that any specific business is guaranteed that price.
Why multiples vary this much by industry
The spread across industries is wide by design, and it’s informative: a laundromat carries an SDE multiple of 3.70×, while a nail salon carries 1.74×. That gap reflects real differences buyers price in — recurring, less discretionary revenue and lower staff turnover for a laundromat; more owner/labor dependence and lower switching costs for many personal-care businesses. A multiple is the market’s summary of how durable and transferable an industry’s earnings tend to be.
The reporting window matters
Every multiple on this site is drawn from a stated, trailing window — currently businesses sold Q3 2021 – Q2 2026, updated biannually. That window is a period, not a permanent constant: a multiple compiled during a strong lending environment will read differently than one compiled during tight credit. Any valuation source that quotes a multiple with no stated date range is asking you to trust a number it won’t let you check.
The main-street segment note
80% of businesses in the source data set sold between $50,000 and $2,000,000 — the “main street” segment. That matters if your business sits well outside that band — a $50,000 side business or a $5,000,000 regional operation may not be well represented by the same average, because the pool of comparable transactions thins out at the edges. Treat the published multiple as most reliable near the center of its own sample.
Average vs. your specific business
The published multiple is an industry average — the starting point, not the answer for your specific business. Within any industry, a business run entirely by its owner on a short-term lease with concentrated customers sells for less than an otherwise-identical business with a manager in place, a secure lease, and a diversified customer base, even at the same SDE. Our valuation calculator prices those adjustments as named, visible line items rather than folding them invisibly into a single number — see our guide on what a business is actually worth for the full breakdown of those factors.
A worked comparison
Take two $150,000-SDE businesses in different industries, both sold at their industry’s average multiple:
| Industry | SDE multiple | Implied sale price on $150k SDE |
|---|---|---|
| Nail salon | 1.74× | $261,000 |
| Laundromat or coin laundry | 3.70× | $555,000 |
Same earnings, more than double the estimated price — purely from the industry the earnings sit in. Look up your own industry’s published multiple, and every other Main Street multiple in the dataset, in the Industry Multiple Lookup.

What a business actually sells for is set by a specific buyer, a specific lender, and a specific deal — no article or calculator can know that in advance, and we say so instead of pretending otherwise.
