How to Value a Small Business: 4 Methods Every Owner Should Know

One of the most common questions business owners ask is: "What is my business actually worth?"

The answer isn't as simple as a single number. Business valuation is part science, part art — and the method you use depends on your industry, business size, and the type of buyer you're targeting.

In this guide, we'll walk through the four primary methods used to value small businesses, when each applies, and how to think about your number before going to market.

Why Valuation Matters Before You Sell

Going to market without knowing your business's value is like listing your house without knowing the neighborhood comps. You'll either price too low and leave money on the table, or price too high and sit on the market until you're forced to cut.

A proper valuation gives you:

• A realistic expectation for what you'll receive
• Leverage in negotiations with buyers
• The ability to reject lowball offers with confidence
• A roadmap for what to improve before listing

Method 1: EBITDA Multiple (Most Common for Operating Businesses)

For the vast majority of profitable small businesses, the EBITDA multiple method is the gold standard. EBITDA — Earnings Before Interest, Taxes, Depreciation, and Amortization — represents the business's true operating profitability.

The formula:

Business Value = EBITDA × Industry Multiple

Example: A plumbing company with $1M in revenue and a 20% profit margin has an EBITDA of $200,000. At a 4x multiple, the business is worth approximately $800,000.

Industry multiples vary significantly. Technology and SaaS companies command 6–10x, while restaurants typically sell for 2–3x. For a full breakdown by sector, see our EBITDA multiples by industry guide.

Normalizing EBITDA

Before applying a multiple, you need to "normalize" your EBITDA — adjusting for items that won't carry over to a new owner:

• Owner's salary above market rate: If you pay yourself $200K but a manager would cost $80K, add back $120K
• Personal expenses run through the business: Travel, vehicles, meals, etc.
• One-time expenses: Legal settlements, equipment purchases, building improvements
• Related-party transactions: Rent paid to a property you own at above-market rates

Normalized EBITDA is almost always higher than your reported EBITDA — and it's what buyers and brokers actually use to value your business.

Method 2: Seller's Discretionary Earnings (SDE) for Owner-Operated Businesses

For smaller businesses — typically under $1M in revenue — buyers often use Seller's Discretionary Earnings (SDE) instead of EBITDA. SDE adds back the owner's total compensation (salary + benefits + perks) on top of EBITDA.

The formula:

SDE = Net Profit + Owner's Compensation + Depreciation + Interest + Taxes + Add-backs

SDE is most relevant when the owner is the primary operator and the business's value is tied to their personal involvement. A buyer acquiring this type of business needs to understand the full economic benefit they'd receive.

Typical SDE multiples range from 1.5x to 3x for small businesses, depending on industry and business risk.

Method 3: Asset-Based Valuation

The asset-based approach values a business by adding up the fair market value of all its assets and subtracting liabilities. This method works best for:

• Businesses with significant physical assets (equipment, inventory, real estate)
• Companies that aren't particularly profitable
• Holding companies or investment entities

Types of asset-based valuation:

• Book Value: Assets minus liabilities per the balance sheet (often understates true value)
• Adjusted Book Value: Assets restated to current fair market value
• Liquidation Value: What you'd get if you sold everything immediately (lowest value)

For most operating businesses, asset-based valuation undervalues the company because it ignores goodwill, customer relationships, and earning power. However, it establishes a floor value — the minimum a rational seller should accept.

Method 4: Market Approach (Comparable Sales)

Similar to how real estate agents use comparable sales ("comps"), the market approach values a business based on what similar businesses have recently sold for.

Business brokers and M&A advisors use databases like BizBuySell, DealStats, and PeerComps to find comparable transactions. They look at:

• Revenue multiples (Price / Revenue)
• SDE multiples (Price / SDE)
• EBITDA multiples (Price / EBITDA)
• Industry, location, size, and growth rate

The challenge is that private business sales are rarely fully disclosed, so comparable data can be sparse — especially for niche industries.

Which Method Is Right for Your Business?

Here's a practical guide:

| Business Type | Primary Method | Secondary Method | |---|---|---| | Profitable operating business | EBITDA multiple | Market comps | | Owner-operated, under $1M revenue | SDE multiple | Market comps | | Asset-heavy (manufacturing, fleet) | EBITDA + asset value | Asset-based | | Unprofitable or pre-revenue | Asset-based | Liquidation value | | SaaS / recurring revenue | Revenue multiple | EBITDA multiple |

Factors That Increase Your Multiple

Not all businesses in the same industry command the same multiple. These factors push your valuation higher:

1. Revenue growth: Buyers pay premiums for growth. Year-over-year revenue increases of 10%+ are highly attractive.
2. Recurring revenue: Contracts, subscriptions, and maintenance agreements reduce buyer risk.
3. Customer diversification: No single customer should represent more than 20% of revenue.
4. Strong management team: A business that runs without the owner commands significantly higher multiples.
5. Clean financials: Well-organized books, professional accounting, and clean tax returns build buyer confidence.
6. Transferable systems: Documented processes, SOPs, and operational systems that don't depend on the owner.

Getting a Professional Valuation

While our free business valuation calculator provides an excellent starting estimate, a certified business appraiser or experienced business broker will give you a more precise number — one you can defend in negotiations.

Professional valuation typically costs $3,000–$10,000 for a formal written appraisal. Many brokers will provide a free opinion of value as part of their listing proposal.

The Bottom Line

Valuing a small business is more nuanced than a simple formula. The right method depends on your business type, size, and the market you're selling in. Understanding all four approaches will make you a far more informed seller — and help you avoid leaving money on the table.
