How Much Is a Small Business Worth? Valuation Ranges by Type

When I say "small business," I mean the ones that make up the vast majority of transactions in the M&A market: companies doing under $5M in revenue, typically with one owner who runs the operation day-to-day. These are HVAC companies, dental practices, landscaping outfits, small e-commerce brands, accounting firms. They represent roughly 70% of all business sales in the United States, and they trade on fundamentally different dynamics than larger companies.

The short answer: most small businesses sell for 2.0 to 4.0 times SDE (Seller's Discretionary Earnings). But the range across industries is wider than most owners expect, and there's a structural ceiling that many sellers don't know about until they're already in a deal.

SDE Multiples by Business Type

Based on our database of 25,000+ real M&A transactions, here are the typical SDE multiple ranges for small businesses (under $5M revenue) across common industries. These are actual transaction data, not theoretical ranges from textbooks.

A few things jump out from this data. Industries with recurring revenue — pest control, managed IT, commercial cleaning with contracts — consistently trade at the higher end. Industries that are highly owner-dependent or have significant client attrition risk — accounting firms, solo medical practices — trade at the lower end. For the full breakdown across 90+ industries, see our complete multiples by industry guide.

The SBA Lending Constraint Most Sellers Don't Know About

Here's something that surprises most first-time sellers: roughly 80% of small business acquisitions are financed through SBA loans. And SBA loans have rules that effectively cap what a buyer can pay for your business.

The key constraint is debt service coverage ratio (DSCR). SBA lenders require that the business's cash flow covers the loan payment by at least 1.25x — meaning the annual cash flow must be 125% of the annual debt service. This creates a mathematical ceiling on the purchase price that no amount of negotiation can overcome.

Let me walk through the math. Say your business has $250,000 in SDE. An SBA 7(a) loan at current rates (roughly 10.5-11% in 2026) on a 10-year term means the maximum loan amount that can be serviced from $250K SDE (divided by 1.25 DSCR) is approximately $1.15M. With 10% buyer equity injection required, the maximum total purchase price is around $1.28M — which works out to about 5.1x SDE.

In practice, most SBA-financed deals happen in the 2.5-4.0x SDE range. The theoretical ceiling of ~5x gets reduced by the buyer's need for a reasonable salary (which comes out of that SDE), working capital requirements, and the reality that lenders apply their own risk adjustments.

Why Size Changes Everything

This is the concept that trips up the most people. The same business model at different sizes trades at completely different multiples. A solo-operator HVAC company doing $600K in revenue might sell for 2.0x SDE. An HVAC company with 15 trucks and $8M in revenue sells for 5-6x EBITDA. Scale fundamentally changes the risk profile and the buyer universe.

There are three inflection points where multiples tend to jump:

Under $500K SDE:This is the "main street" market. Buyers are individuals buying a job. Financing is limited to SBA. Multiples are typically 1.5-3.0x SDE. The owner IS the business.

$500K - $1M SDE:The "lower middle market" transition zone. More sophisticated buyers appear — small PE firms, independent sponsors, experienced operators looking for a platform. The business usually has some management layer beyond the owner. Multiples push to 3.0-4.5x SDE.

$1M+ EBITDA: The true lower middle market. Private equity firms, family offices, and strategic buyers become active. Valuation shifts from SDE to EBITDA. Multiples range from 4-7x EBITDA, and the buyer pool expands dramatically. This is where the size premium really kicks in.

The Role of Seller Financing

In the small business world, seller financing is the norm, not the exception. Even with SBA lending, most deals include a seller note — typically 10-20% of the purchase price, subordinated to the SBA loan, with a 2-3 year term and below-market interest rate.

Here's what you need to understand: a willingness to carry a seller note can increase your sale price by 10-15%. Buyers feel more comfortable paying a higher price when the seller has skin in the game during the transition period. It signals confidence that the business will continue to perform. Conversely, demanding all-cash will shrink your buyer pool and typically reduce the price.

The trade-off is real. You're taking credit risk on the buyer for 10-20% of the purchase price, and if the business fails under new ownership, that note may not get paid. But statistically, the higher sale price more than compensates for the risk in the vast majority of transactions.

What Small Business Buyers Actually Care About

I've sat across the table from hundreds of small business buyers, and they consistently focus on the same things:

Can I pay myself and service the debt?This is always question number one. Buyers run a simple affordability test: take the SDE, subtract the annual debt payment (SBA + seller note), and what's left is their "salary." If that number isn't at least $80-120K for a main street deal, most buyers walk away.

How much will follow the seller out the door?Customer attrition during ownership transitions is the single biggest fear. Smart sellers start their transition plan 12-18 months before the sale: introducing key employees to clients, reducing personal involvement in day-to-day operations, and building systems that don't rely on one person.

What does the trend line look like?Three years of stable or growing revenue and earnings is the magic window. Buyers want to see that the business isn't in decline and that the best days aren't behind it.

What's the lease situation?A favorable long-term lease is worth a lot. A lease that expires in 18 months with no renewal option can kill a deal entirely, because the SBA won't finance a business without location certainty.

Don't Confuse Asking Price with Sale Price

One more thing worth mentioning: when you see businesses listed on BizBuySell or other marketplaces, those are asking prices. The actual sale prices are typically 15-25% lower. Sellers anchor high, buyers negotiate down, and the reality of SBA lending constraints forces the final price to where the math actually works.

This is why getting a data-driven valuation estimate before you go to market is so valuable. You avoid the mistake of listing too high (and sitting on the market for 18 months while serious buyers pass you by) or too low (and leaving hundreds of thousands on the table). The best outcome is pricing your business where the data says it should be and running a competitive process that lets the market tell you the final number.

The Bottom Line

Small businesses are worth what a qualified buyer can afford to pay, financed by what a lender is willing to lend. That sounds circular, but it's the reality of this market. The SBA lending constraint, the SDE multiple ranges for your industry, and the specific factors of your business all converge on a range that's typically narrower than you'd think.

If you want to know where your business falls within these ranges, our valuation tool draws on real transaction data across your specific industry and size to give you a defensible estimate. It's the same data advisors and brokers use when they price a business for market.
