Business valuation is a professional discipline. Market multiples vary widely by industry, growth rate, and economic conditions. This guide explains the most common approaches for educational and planning purposes. A formal appraisal by a Certified Valuation Analyst (CVA) or experienced business broker is essential before making decisions about buying, selling, estate planning, or partner buyouts.
Why Business Valuation Matters
Most small-business owners put the majority of their net worth into their business — yet they have only a vague idea of what it’s worth until they try to sell it. Understanding valuation helps you:
- Set a realistic asking price when selling
- Know what to pay when buying another business
- Plan for estate taxes and business succession
- Structure partner buyout agreements fairly
- Understand how to increase business value before a sale
The Two Main Market Approaches
The most common way to value a privately-held small business is the market approach — comparing the business to similar businesses that have actually sold. There are two variants:
1. SDE Multiple (Small Businesses)
SDE (Seller’s Discretionary Earnings) is the right metric for owner-operated businesses with annual revenue under about $5 million, where the owner works in the business full-time.
SDE = Net Profit + Owner’s Salary and Benefits + Non-recurring/add-back expenses + Depreciation & Amortization
It represents the total economic benefit available to a single owner-operator — how much the new owner could earn from the business before their own salary.
Example: A profitable $800K revenue business with $180K net profit, owner salary of $120K, and $100K in add-backs (one-time legal expense, personal vehicle) = $400K SDE.
At a 2.5× SDE multiple: Enterprise Value = $400,000 × 2.5 = $1,000,000
If the business has $50,000 in liabilities and $10,000 in cash: Equity Value = $1,000,000 − $50,000 + $10,000 = $960,000
2. EBITDA Multiple (Mid-Market Businesses)
EBITDA (Earnings Before Interest, Taxes, Depreciation, and Amortization) is the metric for businesses where a new owner would hire a manager rather than run it themselves — typically $2M+ in revenue.
EBITDA is more comparable across companies because it strips out capital structure (interest) and accounting choices (depreciation), focusing on operating cash flow.
Typical ranges: Lower-middle market ($2M–$10M EBITDA): 4×–7×. Larger or fast-growth businesses can command 8×–12× or more.
Typical SDE Multiples by Business Size
| Annual SDE | Typical Multiple Range | Reason |
|---|---|---|
| Under $150K | 1.5–2.0× | High risk, very owner-dependent |
| $150K–$500K | 2.0–3.0× | Main-street / small business range |
| $500K–$1M | 2.5–3.5× | More scalable, some management |
| $1M–$3M | 3.0–4.5× | Approaching mid-market norms |
| $3M+ | 4.0–5.5× | EBITDA multiples start applying |
These are national averages from BizBuySell and IBBA transaction data. Your specific industry, customer concentration, and growth rate shift the multiple up or down.
What Increases a Business’s Multiple?
Higher multiples go to businesses with:
- Recurring revenue (subscription, contract, retainer) rather than one-time transaction revenue
- Diversified customer base (no single customer >15–20% of revenue)
- Documented, transferable systems and processes (not “all in the owner’s head”)
- Strong online presence, brand recognition, or proprietary technology
- Industry tailwinds (growing market)
- Clean, accurate financial records (3+ years of organized P&L, tax returns)
- Trained management team in place
Lower multiples come from:
- Heavy owner dependence
- Customer concentration (one big client = one big risk)
- Declining revenue trend
- Undocumented or informal operations
- Industry headwinds or disruption risk
Enterprise Value vs. Equity Value
These terms are often confused in small-business transactions:
Enterprise value (EV) is the total value of the business to all capital providers — debt holders and equity owners combined. It’s what you’d pay to buy the entire business free and clear.
Equity value is what the owner actually receives after the debts are paid: Equity Value = Enterprise Value − Total Liabilities + Cash.
In most small-business transactions, the buyer acquires a “debt-free, cash-free” business — meaning: the seller keeps the cash and pays off all business liabilities at closing; the buyer pays the equity value and then brings working capital. This is why enterprise value and equity value are used somewhat interchangeably in small-business discussions (the buyer pays enterprise value; the seller nets equity value after paying off debts).
Sensitivity: Why a Range Matters
Market multiples are averages over hundreds of transactions. Your specific multiple will land somewhere in a range depending on the factors above. A ±0.5× range on a $400K SDE business at 2.5×:
- Low end (2.0×): $800,000
- Mid-point (2.5×): $1,000,000
- High end (3.0×): $1,200,000
This $400,000 swing shows why working with a broker to benchmark your specific business against actual comparable sales is valuable before naming a price.
