It’s the question every business owner asks at some point — usually when retirement starts feeling closer than it used to, when a competitor sells for a number that surprises you, or when an unsolicited offer lands in your inbox.
The honest answer is uncomfortable: your business is worth what a real buyer will actually pay, and that number is rarely the one in your head. Most owners overestimate by 30–50%. Some underestimate by even more.
This guide walks through how small businesses are actually valued in 2026 — the five methods buyers and brokers use, what drives the multiple up or down, and how to get a defensible estimate without spending five figures on a formal appraisal. It’s written for owners of businesses doing roughly $250K to $20M in annual revenue, where most small-business M&A happens.
The Short Answer: Multiples of SDE or EBITDA
For 95% of small businesses, valuation comes down to one formula:
Business Value = Earnings × Multiple
The two key variables:
- Earnings — usually Seller’s Discretionary Earnings (SDE) for businesses under ~$2M in profit, or EBITDA for larger ones
- Multiple — typically 2x to 6x for small businesses, though it varies widely by industry, growth, and risk
So if your business produces $400,000 in SDE and sells at a 3x multiple, it’s worth roughly $1.2M. If you can get to a 4x multiple by reducing risk and showing growth, it’s worth $1.6M — same earnings, $400K more in value.
That gap — between what your business is worth today and what it could be worth — is where most exit planning effort gets concentrated.
Step 1: Figure Out Your Earnings (SDE or EBITDA)
Before you can multiply anything, you need a clean earnings number. This is where most DIY valuations go wrong.
Seller’s Discretionary Earnings (SDE)
SDE is what most small-business buyers actually look at. It represents the total financial benefit a single owner-operator gets from the business.
The basic formula:
SDE = Net Profit + Owner’s Salary + Owner’s Benefits + Interest + Taxes + Depreciation + Amortization + One-time/Non-recurring Expenses
The logic: a buyer is going to step into your shoes and run the business themselves, so they care about every dollar of cash flow available to a working owner — not just what’s on the bottom line of your tax return.
Common add-backs:
- Your salary and any family member salaries above market rate
- Personal expenses run through the business (vehicles, phones, travel, meals)
- One-time legal fees, lawsuit settlements, COVID-era anomalies
- Depreciation and amortization (non-cash expenses)
- Interest on loans the buyer won’t assume
Be honest here. Buyers and their lenders will scrutinize every add-back. Aggressive add-backs that can’t be documented destroy deals.
EBITDA
For larger businesses (typically over $1–2M in profit), buyers shift to EBITDA — Earnings Before Interest, Taxes, Depreciation, and Amortization. EBITDA assumes the buyer will hire a CEO rather than operate the business themselves, so it doesn’t include the owner’s salary as an add-back.
If your business is small enough that you’re personally running it, use SDE. If it has professional management already in place, EBITDA is the right number.
Step 2: Find Your Multiple
This is where most “what’s my business worth” calculators oversimplify. The multiple isn’t a fixed number — it depends on dozens of factors. But there are baseline ranges by industry and size.
Typical SDE Multiples by Industry (2026)
These are rough market ranges based on published M&A data, useful as a starting point only:
- E-commerce / online businesses: 2.5–4x SDE
- SaaS and software: 3–6x SDE (often higher for true subscription businesses)
- Professional services (consulting, agencies): 1.5–3x SDE
- Trades / contracting (HVAC, plumbing, electrical): 2.5–4x SDE
- Restaurants and food service: 1.5–2.5x SDE
- Manufacturing: 3–5x SDE
- Healthcare and dental practices: 2.5–4.5x SDE
- Retail (brick-and-mortar): 1.5–3x SDE
What Pushes Your Multiple Up
A handful of factors can move you from the bottom of the range to the top — or beyond:
- Recurring revenue — subscription, retainer, or contract revenue is worth meaningfully more than one-time sales
- Growth — businesses growing 20%+ annually command premium multiples
- Diversified customer base — no customer over 10% of revenue
- Documented systems and SOPs — the business runs without the owner
- Strong management team — buyers don’t have to be operators
- Clean books — accrual accounting, reviewed financials, consistent reporting
- Defensibility — proprietary technology, contracts, brand, or location moats
- Industry tailwinds — businesses in growing sectors get rerated upward
What Pushes Your Multiple Down
The same factors in reverse:
- Owner dependence — if the business needs you personally, the multiple drops sharply
- Customer concentration — one customer over 20% of revenue is a yellow flag, over 40% is often a deal-killer
- Declining or flat revenue — buyers price in the trajectory
- Inconsistent earnings — wild year-to-year swings reduce buyer confidence
- Industry headwinds — declining or disrupted sectors trade at discounts
- Messy financials — every accounting issue costs you 0.25–0.5x in multiple
- Geographic or supplier concentration — single points of failure
Step 3: Run the Numbers (Three Quick Examples)
Let me show how this plays out with three realistic scenarios.
Example A: Service Business, Owner-Dependent
A 10-year-old marketing agency:
- $1.2M revenue
- $280K SDE (after add-backs)
- 60% revenue from top 2 clients
- Owner handles all client relationships
- No documented processes
Multiple: 1.5x (low end — heavy concentration, owner-dependent) Estimated value: ~$420,000
The same agency with diversified clients (no one over 15%), a director-level employee handling accounts, and documented SOPs might trade at 2.5x — pushing value to $700K. Same earnings, 67% more value.
Example B: E-commerce Brand
A DTC consumer brand:
- $2.1M revenue
- $420K SDE
- 35% repeat customer rate
- Growing 30% YoY
- Diversified product line, multiple sales channels
Multiple: 3.5x (above average — growth + repeat revenue) Estimated value: ~$1.47M
Example C: Established Trades Business
A 25-year HVAC company:
- $4.8M revenue
- $720K SDE
- General manager runs daily operations
- Maintenance contracts make up 30% of revenue
- Established brand in the local market
Multiple: 4x (above range — recurring revenue, professional management, brand) Estimated value: ~$2.88M
The Five Valuation Methods Buyers and Appraisers Actually Use
Most small businesses are valued using SDE or EBITDA multiples, but understanding the alternatives helps you stress-test your number.
1. SDE / EBITDA Multiple (Market Approach)
The dominant method for small business valuation. Earnings × industry-appropriate multiple. Best for: profitable businesses with consistent earnings.
2. Discounted Cash Flow (DCF)
Projects the business’s future cash flows and discounts them back to present value using a risk-adjusted discount rate. The “gold standard” academically, but most small-business buyers don’t use it because the assumptions about the future are too speculative. Best for: high-growth businesses with predictable cash flows.
3. Asset-Based Valuation
Adds up the value of the business’s tangible and intangible assets, minus liabilities. Most useful when a business is asset-heavy (equipment, real estate, inventory) or when the business is unprofitable and being sold for parts. Best for: manufacturing, real estate-heavy businesses, distressed sales.
4. Revenue Multiple
Some industries — especially SaaS and high-growth tech — get valued on revenue rather than profit, because they’re reinvesting profits into growth. Multiples are much lower (typically 0.5x to 4x revenue depending on the model). Best for: pre-profit businesses with strong growth trajectories.
5. Comparable Sales (Comps)
Looking at what similar businesses in your industry actually sold for. The most concrete data point you can get, but small-business sale data is fragmented. BizBuySell publishes general data, and platforms like Capitaliz aggregate transaction data across categories. Best for: validating a number you got from another method.
In practice, sophisticated buyers and appraisers triangulate using two or three methods. If they all land in roughly the same range, you have a defensible number. If they diverge wildly, something needs investigating.
How to Get a Real Estimate
You have three reasonable paths, depending on how serious you are.
Free DIY Estimate
Run the math yourself using SDE × industry multiple. Cross-check with a free online calculator (BizEx, the Western & Southern calculator, and several others give directional estimates). This gets you within ±30% of reality, which is fine for a “should I even consider selling?” decision.
Tool-Based Valuation
Platforms like BizEquity and Capitaliz offer more sophisticated valuation modeling — they pull industry data, ask detailed questions about your business, and produce a multi-method valuation report. Capitaliz is particularly good for owner-managed businesses because it explicitly models the “value gap” between today’s value and what the business could be worth with improvements. Cost is typically $500–$2,000.
The Value Builder System takes a slightly different angle — it scores your business on the eight drivers buyers care about (recurring revenue, customer satisfaction, hub-and-spoke owner dependency, etc.) and gives you a value-builder score. Useful both for valuation and for showing where to focus to increase value.
Professional Appraisal
A certified business appraiser (CVA, ABV, or ASA designation) produces a defensible written valuation. This costs $3,000–$10,000+ and is necessary for legal proceedings (divorce, partner disputes, estate planning) or transactions where the value will be challenged. It’s overkill if you’re just curious or 2+ years from selling.

Common Mistakes That Inflate (or Deflate) Your Estimate
A few patterns that consistently distort owner valuations:
Anchoring on revenue. “My business does $3M in revenue” is not a valuation. Revenue is meaningless without margin. A $3M business with $100K in SDE is worth a fraction of a $1.5M business with $400K in SDE.
Using peer comparisons casually. “My friend sold his business for 6x” — but your friend’s business may have had recurring revenue, a management team, and no customer concentration. The multiple wasn’t free; it was earned.
Ignoring owner add-backs that won’t transfer. Yes, you can add back your salary. But if the buyer will need to hire a $120K manager to do what you do, that comes out somewhere — in price, in earnings projections, or in deal structure.
Forgetting working capital. Most small business deals are sold “free of debt and cash.” If the business needs $200K of working capital to run, that’s typically delivered with the business — meaning you don’t get to keep it. This catches sellers off guard.
Confusing asking price with sale price. Listings on BizBuySell are asking prices. Actual closing prices are typically 10–25% lower. The middle of negotiation is where reality lives.
How Long Until You Need a Real Number?
If you’re more than 2 years from wanting to sell, a directional estimate is fine. Use a free calculator, get a baseline, and start working on the value drivers.
If you’re 6–18 months out, get a tool-based valuation from Capitaliz, BizEquity, or a similar platform. The structured questions will surface issues you can still fix.
If you’re inside 6 months, hire a professional. The cost is trivial relative to a six- or seven-figure transaction, and the report becomes a negotiation tool.
What to Do This Week
Three concrete actions:
- Calculate your SDE for the trailing 12 months. Just the math — net profit + add-backs. Don’t be aggressive; be defensible.
- Look up your industry’s typical SDE multiple range. BizBuySell’s industry data and several broker reports publish this. Pick the middle of the range as your baseline.
- Multiply. That’s your rough valuation. Now ask: what would have to be true for you to be at the top of the range instead of the middle?
That last question is the entire game. The owners who get the highest multiples aren’t necessarily running the best businesses — they’re running businesses that are easiest to evaluate, finance, and transition.
Knowing your number is the first step. Closing the gap between your number today and your number at exit is where the real money is made.
