Ask ten small business owners what their company is worth, and you'll get ten different answers — most of them wrong. Some multiply last year's revenue by a number they heard at a networking event. Others assume "worth" means "what I've put into it." Neither approach holds up when a real buyer shows up with a term sheet.
Here's the number that actually matters: in Q1 2026, the median small business sold for $350,000 on $165,256 of median cash flow — a 2.7x multiple. That's the market-wide average. But averages hide enormous variation. A car wash with the same cash flow as a retail shop can sell for nearly double, simply because of what industry it's in and how its earnings get calculated.
If you own a business — whether you're planning to sell next year or just want to know where you stand — understanding valuation multiples isn't optional. It's the difference between negotiating from strength and leaving six figures on the table.
SDE vs. EBITDA: The Metric You Use Changes the Number
Before any multiple means anything, you need to know which earnings figure it's being applied to. The two most common are Seller's Discretionary Earnings (SDE) and EBITDA (Earnings Before Interest, Taxes, Depreciation, and Amortization), and confusing them is one of the fastest ways to misjudge your own value.
SDE adds back the owner's total compensation — salary, benefits, perks, and any personal expenses run through the business — to reflect the full economic benefit available to a single owner-operator. It's built for buyers who plan to run the business themselves.
EBITDA does not add back owner compensation. It assumes a business is large enough to need a market-rate manager, so that salary stays in the expense column. It's built for buyers — often private equity or larger strategic acquirers — who plan to install management and run the business as a portfolio asset.
The size of your business generally determines which one applies:
- Under $5 million in value: use SDE, add back your salary and discretionary costs.
- $2 million–$5 million: median SDE multiple around 3.65x, EBITDA around 4.09x.
- $5 million–$10 million: median SDE multiple around 4.18x, EBITDA around 4.6x.
- Above $5–10 million: buyers increasingly value the business on EBITDA alone.
The gap between the two isn't cosmetic. Take a business with $500,000 in net profit and $200,000 in owner compensation. Its SDE is $700,000. Its EBITDA is $500,000. At a typical 3x SDE multiple, that's a $2.1 million valuation. At a typical 5x EBITDA multiple, it's $2.5 million. Get the metric wrong — or let a buyer quietly apply the wrong one to your numbers — and you can misprice your own company by hundreds of thousands of dollars without anyone raising their voice.
Why Industry Changes Everything
Once you know which earnings metric applies, the multiple itself is driven almost entirely by industry. Buyers pay more for recurring revenue, licensing barriers to entry, and predictable demand — and noticeably less for businesses that live and die on the owner's personal relationships or face constant new competition.
Here's how the market breaks down for businesses under roughly $10 million in enterprise value:
| Industry | Typical Multiple | Why |
|---|---|---|
| SaaS / software | 6–10x EBITDA (or 3–8x ARR) | Recurring revenue, high margins, scalable |
| Healthcare services | 5–8x EBITDA | Licensing barriers, insurance-backed demand |
| Car washes | ~5.8x (up to 8x for express models) | Recurring visits, real estate upside, PE interest |
| HVAC | 4–7x EBITDA | Recurring service contracts, active PE roll-ups |
| Manufacturing | 4–7x EBITDA | Contracts, equipment, barriers to entry |
| Self-storage | ~4.6x | Low overhead, real estate component |
| Plumbing | 3.5–5.5x EBITDA | Recurring demand, less consolidated than HVAC |
| Professional services | 3.5–6x EBITDA | Depends heavily on owner involvement |
| Home services (general) | 3.5–6x EBITDA | Fragmented, quality varies by operator |
| Laundromats | ~4.0x | Passive, cash-based, but slower growth |
| Restaurants | Lowest end of the range | Thin margins, high failure rate, low barriers to entry |
Notice what the top of the list has in common: recurring revenue, some form of contractual or physical lock-in, and active buyer competition — particularly from private equity groups doing "roll-up" acquisitions in HVAC, plumbing, dental, and car washes. The bottom of the list shares the opposite traits: thin margins, easy-to-replicate operations, and a business that lives or dies on the current owner showing up every day.
The Car Wash Case Study
Car washes are the poster child for why "know your industry multiple" matters more than "know your revenue." Express car washes are trading at 5x–8x adjusted EBITDA in 2026, with a typical deal landing around 6.5x — nearly double the 2.7x economy-wide median.
Two things drive this. First, car washes generate highly recurring, subscription-like revenue (monthly unlimited-wash memberships are now standard), which buyers treat the same way they'd treat SaaS churn — a bankable, predictable cash flow stream. Second, many car wash sales include the underlying real estate, which adds an entirely separate asset class to the deal, widens the buyer pool, and gives lenders collateral to work with. Sellers who let a buyer "blend" the real estate value into the operating multiple instead of pricing it separately routinely leave 15–30% of total deal value on the table.
The lesson generalizes well beyond car washes: if your business owns real estate, equipment, or any other asset with independent market value, that value should never simply be absorbed into your earnings multiple. Price the operating business and the hard assets separately, then add them together.
What Actually Moves Your Multiple (Besides Industry)
Industry sets your starting range. Everything else about how you run the business determines where you land inside — or outside — that range.
Owner dependence. A business that runs fine for three weeks while the owner is on vacation is worth more than one that falls apart in three days. Buyers discount heavily for "key person risk," especially in professional services and trades.
Revenue concentration. If one customer accounts for more than 10-15% of revenue, expect buyers to discount the multiple or structure an earnout tied to retaining that customer. Diversified revenue is safer revenue.
Growth trajectory. A flat business and a growing business in the same industry do not get the same multiple. Q1 2026 data shows sophisticated buyers driving up valuations specifically for strong-performing businesses while demand softened sharply for businesses with flat or declining financials — the gap between winners and laggards is widening, not narrowing.
The quality of your financial records. This is the one lever entirely within your control, starting today, regardless of industry — and it's the one most owners underestimate.
The Multiple You Lose to Messy Books
Here's the part that should change how you think about bookkeeping, starting well before you ever list your business for sale.
Clean financial statements with minimal, well-documented add-backs routinely add a quarter- to half-point to your valuation multiple. That sounds small until you run the math: a half-point multiple improvement on a business doing $2 million in EBITDA is a $1 million increase in sale price — for the same underlying business, with the same customers, same revenue, same equipment. The only thing that changed is whether a buyer trusts your numbers.
The mechanism is due diligence. Every serious buyer — and certainly every private equity or institutional buyer — runs some version of a Quality of Earnings analysis, scrutinizing revenue quality, normalized expenses, and working capital needs before they'll sign anything. If your books are clean, that analysis simply confirms what you've already told them, and the deal moves fast. If your books are a mess of commingled personal expenses, undocumented cash transactions, and add-backs you can't fully explain, every one of those items becomes a negotiating point — or a reason to walk away entirely. Analysts estimate that 70-90% of M&A deals that fail in due diligence trace the failure back to poor financial records, not a bad underlying business.
Well-organized financials with minimal add-backs can lift sale prices by 20-30% relative to comparable businesses with sloppy books, because buyers are pricing in less risk and less negotiating friction. Two or more years of clean statements means your add-backs are minimal and easily justified line by line, buyers gain confidence faster, and the conversation shifts from "prove this number is real" to "let's talk about growth potential" — which is exactly the conversation you want to be having when the price gets set.
The takeaway isn't just for owners actively courting a buyer. If there's any chance you'll sell in the next three to five years, the best time to start keeping investor-grade books was three years ago. The second-best time is today.
