How to Value a Small Business: A Practical Guide for Owners Thinking About Exit
If you own a small business and are starting to think about an exit — whether that means selling in two years or ten — understanding how buyers will value your company is one of the most practical things you can do right now. The number a buyer arrives at may feel arbitrary or surprising. It doesn’t have to. The frameworks are knowable, and understanding them gives you real advantages in a sale process.
This post focuses specifically on the valuation approaches that apply to smaller businesses — typically those with under $10 million in enterprise value — and explains the practical rules of thumb that drive most transactions at this deal size. For the full methodology overview that applies across deal sizes, see our pillar guide on business valuation methods.
The Core Metric: Seller’s Discretionary Earnings (SDE)
For owner-operated businesses where the owner is also the primary operator, buyer valuation typically starts with seller’s discretionary earnings (SDE) rather than EBITDA. SDE is calculated by taking net income and adding back: the owner’s salary and benefits (since a buyer will account for the owner’s role differently), interest, taxes, depreciation, amortization, and any one-time or personal expenses run through the business.
The resulting SDE figure represents the total financial benefit available to a single full-time owner-operator. It is the most relevant earnings metric for buyers of small businesses because it reflects economic reality better than EBITDA when owner compensation is a material part of the cost structure.
Typical SDE Multiples by Industry
- Service businesses (general): 2x–3.5x SDE
- Professional services firms: 2.5x–4x SDE
- Property management companies: 3x–5x SDE
- Construction and trades: 2x–3.5x SDE
- Retail businesses: 1.5x–2.5x SDE
These are ranges, not formulas. Where your business lands within the range — or whether it trades above it — depends on the factors below.
What Drives Multiples Up
Recurring or contracted revenue. Buyers pay premiums for predictability. A service business with multi-year contracts or historically low customer churn trades at a higher multiple than one that re-earns its revenue year to year. Even month-to-month agreements with stable renewal history are valued more favorably than fully transactional revenue.
Low owner dependence. The buyer needs to believe the business will continue performing without you. A business where all key customer relationships, institutional knowledge, and operational decisions run through the owner is discounted accordingly. Investing in management depth and documented processes before going to market improves value in a measurable way.
Customer diversification. Concentration in any single customer — particularly above 15–20% of revenue — is a risk factor buyers price explicitly. Addressing concentration before going to market, if possible, is worth the effort.
Clean financials. Unexplained variances, informal revenue recognition, and personal expenses commingled with business records reduce buyer confidence and, as a direct consequence, price. Buyers who cannot readily verify your earnings build a discount into their offer. Our framework for preparing to sell your business and maximize value covers the cleanup steps that make the biggest difference here.
The Legal Piece
Purchase price is a headline number. What you actually net from a sale depends on deal structure, earnout terms, working capital adjustments, seller note provisions, escrow holdbacks, and the representations you make in the purchase agreement. A seller who focuses only on the LOI price — without understanding how those other terms affect their net proceeds — often leaves significant value on the table.
Experienced transaction counsel helps you understand the full economic picture of a deal, not just the number on the letter of intent.
