How to Value a Small Business for Sale

Deciding to sell your business is often the biggest financial decision of your life. Getting the price right is the difference between a comfortable retirement and leaving money on the table. While gut instinct plays a role, professional valuation relies on concrete financial formulas, specifically SDE (Seller’s Discretionary Earnings) and EBITDA. Here is how to navigate the math behind a profitable exit.

The Two Main Valuation Formulas: SDE vs. EBITDA

Before you can apply a multiple, you must determine which earnings metric applies to your specific business size. Small businesses and lower-middle-market companies use different yardsticks.

1. Seller’s Discretionary Earnings (SDE)

This is the standard metric for “Main Street” businesses. If your company generates less than $1 million in earnings or has under $5 million in revenue, buyers will likely use SDE.

SDE calculates the total financial benefit a single full-time owner-operator derives from the business. Because small business owners often run personal expenses through the company to reduce tax liability, net income on a tax return rarely reflects the true cash flow.

The SDE Formula:

  • Net Profit (from tax returns)
  • (+) Owner’s Salary
  • (+) Depreciation & Amortization
  • (+) Interest Expenses
  • (+) Non-recurring expenses (one-time legal fees, patent costs)
  • (+) Discretionary expenses (personal vehicle, personal travel, family health insurance)

Why it matters: Buyers of businesses this size are usually individuals buying a job. They want to know exactly how much cash the business generates to pay their own salary and service the debt used to buy the company.

2. EBITDA (Earnings Before Interest, Taxes, Depreciation, and Amortization)

This metric is typically reserved for larger businesses with over $1 million in earnings. At this level, buyers are often private equity firms or strategic competitors. These buyers will not run the business themselves; they will hire a General Manager. Therefore, the owner’s salary is considered a real expense, not an add-back.

Understanding the Multiples

Once you have calculated your SDE or EBITDA, you apply a “multiple” to determine the sale price. This is where market conditions and specific business strengths come into play.

Typical SDE Multiples

For most small businesses, the sales price is usually between 2.0x and 3.0x SDE.

  • 2.0x SDE: This usually applies to businesses where the owner is heavily involved in daily operations, growth is flat, or the equipment is aging.
  • 3.0x SDE: This is a strong target for businesses with consistent growth, clean books, and established staff.
  • 4.0x SDE and above: These premiums are rare for brick-and-mortar small businesses but common for SaaS (Software as a Service) companies, businesses with high intellectual property, or firms with 10-year government contracts.

Example Calculation: If your print shop shows a net loss of $10,000 on taxes but has $150,000 in legitimate add-backs (salary, depreciation, car lease), your SDE is $140,000.

  • Valuation at 2.5x multiple: $350,000.

Factors That Increase Your Multiple

You can push your multiple from the lower end (2.2x) to the higher end (3.0x+) by addressing specific risk factors buyers hate.

  1. Transferability: If the business relies on your personal relationships with clients, the value drops. If customers are loyal to the brand or product, the value rises.
  2. Recurring Revenue: A heating and cooling company with 500 annual service contracts is worth significantly more than a construction company that must bid on every new project. Recurring revenue creates safety for the buyer.
  3. Customer Concentration: If a single client accounts for more than 15% to 20% of your total revenue, buyers will heavily discount the price. Losing that one client could bankrupt the new owner.
  4. Growth Trend: Three years of declining sales suggests a dying business. Three years of 10% year-over-year growth suggests potential.

The Market Approach vs. Asset Approach

While the income approach (Multiples of SDE) is the most common, you should be aware of other methods used to sanity-check the price.

The Market Approach

This method compares your business to similar businesses that have sold recently. Resources like the BizBuySell Insight Report or peer data from brokerage firms allow you to see what similar companies in your industry are actually selling for. For example, dental practices often sell for a percentage of annual collections (often 70% to 80%) rather than strictly on EBITDA.

The Asset-Based Approach

This is generally the “floor” of your valuation. If your business is losing money or has very low margins, it may be valued solely on its tangible assets. This is the liquidation value: inventory, equipment, real estate, and furniture minus liabilities. If your SDE valuation is lower than your asset value, you are better off liquidating the assets than selling the business as a going concern.

Getting Your "Add-Backs" Approved

The most contentious part of valuing a small business is the “add-back” schedule during Due Diligence. You might claim your annual retreat to Hawaii was a business expense, but a buyer might reject that add-back if there is no proof business was conducted.

To defend your valuation, you must have clean documentation. If you claim $50,000 in cash income that was never deposited in the bank, you cannot use it in your valuation. Buyers and banks will only pay for what they can verify on tax returns and bank statements.

Frequently Asked Questions

Can I value my business based on revenue?

Generally, no. While some industries use revenue rules of thumb (like accounting firms selling for 1x revenue), smart buyers focus on profit. A business with $2 million in revenue and $50,000 in profit is worth less than a business with $500,000 in revenue and $200,000 in profit.

What is the difference between an asking price and a clearing price?

The asking price is what you list the business for. The clearing price is what it actually sells for. According to industry data from platforms like BizBuySell, small businesses typically sell for roughly 90% of the original asking price.

Does inventory count in the multiple?

Usually, inventory is calculated separately. The standard listing structure is “Price + Inventory.” This prevents the seller from depleting inventory right before the sale. The buyer pays the agreed multiple for the business operations and then pays dollar-for-dollar for usable inventory at the time of closing.

How much does a professional valuation cost?

A simple Broker’s Opinion of Value (BOV) is often free if you list with a broker. A certified valuation for tax or legal purposes from a credentialed appraiser can cost between $3,000 and $10,000 depending on the complexity of the organization.
