How Much Can I Sell My Business For? The Real Math

Most business owners who ask me this question already have a number in their head. Almost always, that number is wrong by 30 to 50 percent.

That is not a knock on the people asking. It is human nature. You built the thing. You know what it cost you in time, money, and lost weekends. You assume that effort translates into market value. It does not.

Here is the honest answer. If you run an owner-operated business with under $2 million in earnings, your sale price is going to land somewhere between 2 and 4 times your Seller's Discretionary Earnings (SDE). If you are larger and run by a management team, you are looking at roughly 4 to 8 times EBITDA. Industry, customer mix, growth trends, and how dependent the business is on you will move you up or down inside that range. That is the math the market actually uses, whether you like it or not.

The Short Version

• For most owner-operated businesses, sale price equals SDE multiplied by an industry-specific factor between 2.0x and 4.0x.

• Businesses with EBITDA above roughly $2 million transition to EBITDA multiples in the 4x to 8x range.

• The IBBA's Q3 2025 Market Pulse data shows median multiples of 2.0x SDE under $500K, 2.8x SDE between $500K and $1M, 3.0x SDE between $1M and $2M, and 4.8x EBITDA between $2M and $5M.

• Recurring revenue, customer diversification, and a business that runs without you push your multiple up. Customer concentration above 20%, declining trends, and heavy owner involvement push it down.

• BizBuySell reported that businesses sold in 2025 closed at a median of 94% of asking price, but the smallest deals routinely sold for 85% or less.

The Quick Math: What Your Business Is Probably Worth

Every small business sale comes down to one core formula. You take a measure of profit, you multiply it by a number, and you adjust for what you own and what you owe. That is it.

For owner-operated businesses, the profit number is called Seller's Discretionary Earnings, or SDE. SDE is your net income, plus your salary, plus the perks you run through the business (the truck you write off, the family member on payroll, the personal phone, the conferences in Florida that doubled as vacations), plus depreciation, plus any one-time expenses that are not going to repeat for the buyer. The point of SDE is to show what a single owner-operator actually pulls out of the business in a year.

For larger businesses with professional management, the number is EBITDA, which strips out interest, taxes, depreciation, and amortization but assumes a market-rate salary for whoever runs the place. There is a guide on this site that walks through SDE vs. EBITDA in more detail, and it is worth reading before you put a number on yourself. Mixing the two up is one of the most expensive mistakes I see.

The multiple you apply to that profit number is the second piece of the puzzle, and it is set by the market, not by you. According to BizBuySell's 2025 Year in Review, the average cash flow multiple across more than 9,500 closed transactions in 2025 was 2.61x SDE. The all-industry median has hovered between 2.5x and 2.7x for years.

What's the difference between SDE and EBITDA?

SDE adds back the owner's full compensation and personal perks because a small business buyer is going to step into the owner's shoes and take the same benefit. EBITDA does not add back the owner's salary because it assumes a hired manager runs the place. For a business under roughly $2 million in earnings, use SDE. For a business above that, use EBITDA. Apply the wrong one and your value can swing by hundreds of thousands of dollars.

What's a Realistic Multiple for Your Size?

Multiples scale with size. The bigger the business, the higher the multiple, because bigger businesses come with management depth, financing access, and lower buyer risk. The IBBA tracks this every quarter through their Market Pulse Survey, and the numbers are remarkably stable.

Here is what the most recent quarter (Q3 2025) showed:

Enterprise Value (Sale Price)	Median Multiple	Method Used
Under $500,000	~2.0x	SDE
$500,000 to $1M	~2.8x	SDE
$1M to $2M	~3.0x	SDE
$2M to $5M	~4.8x	EBITDA
$5M to $50M	5.3x to 6.0x	EBITDA

A few things to notice. The jump from a $1.9 million business to a $2.1 million business is not just $200K of earnings. The multiple itself jumps from roughly 3x SDE to closer to 5x EBITDA, because you have crossed the threshold where private equity and institutional buyers start paying attention. That is why I tell sellers approaching that line that an extra year of growth before listing can be worth significantly more than the revenue itself adds.

Also notice the bottom of the chart. Sub-$500K businesses have been stuck at 2.0x SDE for over a decade. That is not changing. If you have a business doing $300K in SDE and someone is telling you it is worth $1.5 million, they are either inflating the broker opinion to win your listing or they have no idea what they are doing. Owners who want a credible read on where they stand should look into proper exit planning before they list, not after.

Industry Matters Almost as Much as Size

Within those size brackets, your industry sets the realistic ceiling and floor. A laundromat and a marketing consultancy with the same SDE will not sell for the same number, and they should not.

Here are some of the industry medians from BizBuySell's 2025 data:

• Service businesses (cleaning, pest control, professional services): 2.0x to 3.0x SDE

• Construction and trades (HVAC, plumbing, electrical): 2.5x to 3.5x SDE for smaller, 4x to 6x EBITDA for larger

• Manufacturing: 2.7x to 3.5x SDE for smaller, climbing to 9x EBITDA for tech-enabled or automated operations

• Healthcare practices: 2.5x to 4.5x SDE for Main Street, 5x to 11x EBITDA for platform deals

• Retail (brick-and-mortar): 1.5x to 2.5x SDE

• Restaurants: roughly 2.0x SDE, with thin margins compressing the range

• E-commerce and online businesses: 2.0x to 3.5x SDE, higher for content sites with stable traffic

• Specialty operations like marinas, car washes, storage facilities, and laundromats: 4x to 6.6x SDE

The pattern is consistent. Industries with recurring revenue, high barriers to entry (licensing, real estate, regulatory hurdles), and stable cash flow get rewarded. Industries with thin margins, location dependency, and easy entry get punished.

What Pushes Your Multiple Up or Down

Once you know your industry and size median, the real question is where you fall inside that range. The answer comes down to risk. Buyers pay premiums for businesses they believe will keep performing after the seller is gone, and they discount businesses that look like they will collapse without the owner.

Things that push your multiple up:

• Recurring or contracted revenue above 60 percent of total revenue (premium of roughly 20% to 50% on the multiple)

• Top customer below 10% of revenue

• Documented systems and a real second-tier management team

• Three-plus years of clean, accountant-reviewed financials

• Year-over-year growth above 15%

• Long-term lease at below-market rent

• Owner working under 30 hours a week in the business

Things that push your multiple down:

• One customer over 20% of revenue (10% to 20% multiple compression)

• One customer over 30% (a 1x to 2x EBITDA haircut, and many SBA lenders will not finance the deal)

• Owner is the brand, the salesperson, and the technician (15% to 25% discount, sometimes more)

• Declining revenue trend (15% to 30% multiple compression)

• Sloppy books that need reconstruction

• Single location with no portability

How does customer concentration affect sale price?

Customer concentration is one of the fastest ways to lose six figures of value at closing. Buyers and lenders treat any single customer over 15 to 20 percent of revenue as concentration risk. Above 30 percent, many SBA lenders and private equity firms refuse to fund the deal at all. I have seen two nearly identical service businesses sell at very different prices solely because one had a 30% customer and the other had a clean spread of small accounts.

The Mistakes That Cost Owners Real Money

I want to be blunt here, because being polite about this costs people money.

The biggest mistake is what I call the retirement number trap. The owner figures out what he needs to retire, divides it by some multiple he heard at a chamber of commerce lunch, and announces that as his asking price. The market does not care what you need. The market cares what your business earns and what comparable businesses have actually sold for in the last twelve to eighteen months.

The second biggest mistake is valuing on revenue. I had a conversation with a guy running a regional distribution business doing $4 million in top-line revenue who was sure his business was worth $4 million. His SDE was about $180,000. At a generous 3x SDE multiple, his business was worth somewhere around $540,000. The revenue number was a vanity metric. He had been telling himself the wrong story for years.

A few other patterns I see over and over:

• Confusing sweat equity with market value. The years you put in are real, but a buyer is paying for future cash flow, not your past sacrifice. Period.

• Applying EBITDA multiples to SDE numbers. If you add back your $150K salary on a small business and then apply a 5x multiple, you have just inflated your value by $750K out of thin air.

• Trusting one rule of thumb. "Service businesses sell for 1x revenue" is a great way to leave a quarter million dollars on the table or run a stale listing for 18 months.

• Failing to recast the books properly. Most tax returns understate true earnings because they are written to minimize taxable income. If you do not normalize the numbers, your starting point is wrong.

That whole list is exactly what we walk through with sellers during seller advising engagements, and it is also why I do not trust most online valuation calculators. They cannot ask you any of the right questions.

Why do most owners overestimate what their business is worth?

Three reasons. First, the endowment effect, a real behavioral pattern in which owners assign more value to something they own than to an identical asset they do not. Second, owners conflate sweat equity with market value, even though buyers only pay for future cash flow. Third, owners often hear what comparable businesses asked for and assume that was the sale price. Asking is not selling.

When to Trust a Calculator and When to Get a Real Valuation

A free online calculator or a broker opinion of value is fine if you are 12 to 24 months out and just want to know whether selling makes sense. It is not fine if you are headed into a divorce, an IRS estate filing, a partnership buyout, an SBA loan underwriting, or any litigation involving the business. Those situations require a certified valuation from a credentialed appraiser, and an estimate will not hold up.

Cost-wise, here is what to expect:

• Free to $500 for an online calculator or broker opinion of value

• $1,500 to $4,000 for a standard non-certified valuation

• $7,000 to $10,000 for a certified valuation suitable for IRS, court, or lender purposes

• $10,000 and up for complex multi-entity or holding company appraisals

If you are within six months of going to market, want to settle a partnership buyout cleanly, or just want a defensible number to anchor negotiations, the certified path is worth it. Our team handles preliminary business valuations for sellers who are not yet ready to list but want a credible number to work toward.

When should I get a formal business valuation?

Get a formal valuation when the number has to hold up to outside scrutiny. That includes IRS estate or gift tax filings, divorce proceedings, partnership disputes, ESOP formation, SBA loan underwriting, and any litigation involving the business. It is also worth the cost when you are within six months of listing, when there is a specific buyer in negotiation, or when you need a defensible number to anchor a partnership or family transaction. If you are using the next year or so to prepare your business for sale, a preliminary valuation up front gives you a target to work toward.

What This Looks Like in the Real World

Let me ground all of this in a typical example.

I had a client running a regional commercial cleaning company a while back. Revenue was around $2.6 million. Net income on the tax return was $140,000. The owner was paying himself $185,000, running a vehicle and family phones through the business worth about $24,000 a year, and had taken a $40,000 one-time legal expense the prior year defending a frivolous suit. So the recast SDE was about $389,000.

His industry median for cleaning services was around 2.5x SDE, but his book of business was 70 percent contracted, his top customer was only 9 percent of revenue, and he had a manager running daily operations. We were able to pitch the business at the upper end of the range. It listed at 3.4x SDE, drew multiple offers, and closed within 5% of asking price. The buyer financed it through an SBA loan, and the whole process from listing to close ran a touch under six months.

That same business with sloppy books, a 35% top customer, and the owner answering every service call himself? Same revenue, same on paper, but it would have struggled to clear 2.0x SDE and probably would not have qualified for SBA financing at all. Same business in the data. Different price by close to a million dollars.

That is the difference between getting it right and guessing.

What to Do With This

If you have read this far, you probably have a more grounded sense of where your business actually sits than you did 10 minutes ago. The next step is doing the recast on your numbers, comparing to industry medians, and being honest with yourself about the factors that move the multiple. If you also want a realistic read on the timeline to sell a business of your size and type, that is worth knowing before you commit.

Frequently Asked Questions

How do I calculate what my small business is worth?

Calculate Seller's Discretionary Earnings: net income plus owner salary, plus perks, plus non-recurring expenses, plus depreciation. Multiply by your industry's median multiple, typically 2x to 4x for owner-operated businesses. Adjust up for recurring revenue, low customer concentration, and management depth. Adjust down for owner dependence, customer concentration, or declining revenue. Cross-check against asset value and revenue multiples.

What is the average sale price of a small business in 2025?

According to BizBuySell's 2025 Year in Review, the median sale price for a closed Main Street business in 2025 was $350,000 with a median cash flow of around $159,000. The average cash flow multiple was 2.61x SDE across more than 9,500 transactions. Sale prices vary significantly by industry and size, with manufacturing and healthcare commanding higher prices than restaurants and retail.

How long does it take to sell a business?

The median Main Street business takes roughly 168 to 170 days from listing to close, per BizBuySell data. Lower-middle-market deals often run 6 to 12 months due to more complex due diligence and financing. Total time including pre-listing preparation typically runs 12 to 18 months for owners who have not started preparing in advance.

Can I sell my business without a broker?

You can, but most owners who try get a worse outcome. Reasons include limited buyer reach, no negotiating buffer, weaker confidentiality, no help with deal structure or financing, and the time drain of running a sale process while operating the business. The fee a broker earns is almost always recovered through a higher sale price and better terms.

What is my business worth if I am not profitable?

A business with no profit is typically valued on its assets. Add up the fair market value of equipment, inventory, and any real estate, then subtract liabilities. The result sets a floor value. In some cases, businesses with strong revenue but no profit (often early-stage e-commerce or SaaS) can be valued on a revenue multiple of 0.5x to 2x, though buyers will be skeptical.
