How to Value a Small Business: Valuation Multiples by Industry (2026)

How to Value a Small Business Using SDE Multiples

If you want to know how to value a small business, start with SDE multiples. Small business valuation is the process of determining fair market value based on the seller's discretionary earnings and an industry-specific multiple. Take the SDE, multiply by the right number, and you get a reliable estimate of what the business is worth.

The formula looks like this: Business Value = SDE x Industry Multiple

A business generating $200,000 in SDE with a 2.5x multiple is worth roughly $500,000. That same $200,000 in SDE with a 5.0x multiple puts the value at $1,000,000. The multiple is what separates a deal that makes you wealthy from one that buries you in debt.

If you are not sure how to calculate SDE, read our guide to calculating seller's discretionary earnings first. Getting SDE wrong means the multiple is applied to the wrong base number, and the entire valuation falls apart.

2026 SDE Multiples by Industry

The table below shows typical SDE multiple ranges for 20 common small business industries. These ranges reflect businesses with annual SDE between $100,000 and $1,000,000. Larger businesses within each industry tend to trade at the higher end. Smaller, riskier, or more owner-dependent businesses trade at the lower end.

Industry SDE Multiple Range Median
Auto Repair 2.0x - 3.0x 2.5x
Restaurant 1.5x - 2.5x 2.0x
HVAC 2.5x - 3.5x 3.0x
Plumbing 2.0x - 3.0x 2.5x
SaaS 4.0x - 8.0x 5.5x
E-commerce 2.5x - 4.0x 3.0x
Laundromat 2.5x - 4.0x 3.0x
Manufacturing 3.0x - 5.0x 4.0x
Retail 1.5x - 2.5x 2.0x
Dental Practice 1.5x - 2.0x 1.75x
Professional Services 2.0x - 3.5x 2.5x
Construction 2.0x - 3.0x 2.5x
Home Services 2.0x - 3.0x 2.5x
IT Services 3.0x - 5.0x 4.0x
Salon and Spa 1.5x - 2.5x 2.0x
Veterinary 2.5x - 3.5x 3.0x
Healthcare 3.0x - 5.0x 4.0x
Transportation 2.0x - 3.0x 2.5x
Pet Services 2.5x - 3.5x 3.0x
Accounting 2.0x - 3.0x 2.5x

These multiples apply to asset sales, which is how most small business transactions are structured. They do not include real estate. If the business owns the building, that is valued separately, typically based on a commercial appraisal or cap rate analysis.

What Drives Multiples Higher

Not every HVAC company sells for the same multiple. A well-run operation with recurring revenue, trained technicians, and diversified customers will command 3.5x. A one-truck operation where the owner does every install will struggle to get 2.5x. Here are the factors that push multiples toward the top of the range.

  • Recurring revenue. Service contracts, subscriptions, and maintenance agreements create predictable cash flow. Buyers pay more for predictability. An HVAC company with 400 maintenance contracts is worth significantly more than one that relies entirely on one-time repair calls.
  • Low owner dependency. If the business runs without the owner present every day, it is more transferable. Buyers want to step into a system, not become the system. A business with a general manager handling daily operations commands a premium.
  • Revenue growth. Three consecutive years of 10%+ revenue growth signals a healthy business in a growing market. Flat or declining revenue compresses multiples fast.
  • Customer diversification. No single customer should represent more than 10% to 15% of revenue. Heavy concentration means losing one account could sink the business. Learn more about concentration risk and other red flags.
  • Strong margins. Gross margins above industry average suggest pricing power, operational efficiency, or both. Thin margins leave no room for error and scare buyers away.
  • Clean financials. Businesses with professionally prepared financial statements, separate business and personal expenses, and three or more years of consistent tax returns trade at higher multiples. Messy books create uncertainty, and uncertainty lowers price.
  • Defensible market position. Proprietary technology, exclusive territories, long-term contracts, or strong brand recognition all create barriers to entry that protect future cash flow.

What Pushes Multiples Lower

The same factors work in reverse. Here is what compresses valuation multiples.

  • Owner dependency. If the owner is the primary salesperson, the main technician, and the only person who knows the customers, the business may not survive the transition. Buyers discount heavily for this risk.
  • Declining revenue. Two or more years of revenue decline signals a structural problem. The multiple drops, and buyers often walk away entirely.
  • Customer concentration. If one customer represents 30% or more of revenue, the business has a single point of failure. Multiples drop by 0.5x to 1.0x for concentration risk alone.
  • Deferred maintenance. Equipment that needs replacement, facilities that need repair, and technology that needs upgrading all represent hidden costs. These costs come directly off the effective purchase price.
  • Industry headwinds. Businesses in declining industries or facing regulatory changes trade at lower multiples regardless of current performance.
  • Inconsistent financials. Large year-over-year swings in revenue or profitability make it hard to project future earnings. Buyers use the worst year as their baseline, not the best.

Worked Example 1: HVAC Company

An HVAC business in Texas generates $350,000 in SDE. The owner has 300 residential maintenance contracts generating $180,000 in annual recurring revenue. The company employs 6 technicians and a full-time office manager. Revenue has grown 8% annually for three years. No customer represents more than 3% of revenue.

This business hits several premium indicators: recurring revenue, low owner dependency, growth, and diversification. It should trade at the upper end of the HVAC range.

  • SDE: $350,000
  • Multiple: 3.3x (upper end of 2.5x - 3.5x range)
  • Estimated Value: $350,000 x 3.3 = $1,155,000

With a 10% down payment on an SBA loan, the buyer needs $115,500 in cash to close this deal. Annual debt service on a $1,039,500 loan at 7.5% over 10 years is roughly $147,000, leaving $203,000 in pre-tax cash flow to the new owner.

Worked Example 2: SaaS Business

A B2B SaaS product serves 850 paying customers at an average of $99 per month. Annual recurring revenue is $1,009,800. Monthly churn is 2.1%. The sole founder handles product decisions and major customer relationships. Two part-time contractors handle support. SDE is $480,000.

The strong recurring revenue and healthy customer count push the multiple up. But the high churn rate (2.1% monthly means roughly 22% annual churn) and heavy founder dependency pull it back down. This business is unlikely to command top-tier SaaS multiples.

  • SDE: $480,000
  • Multiple: 4.5x (lower-middle of 4.0x - 8.0x range)
  • Estimated Value: $480,000 x 4.5 = $2,160,000

A buyer paying $2.16M for this business needs to solve two problems fast: reduce churn and hire someone to replace the founder's daily involvement. If churn drops to 1% monthly and a product manager takes over operations, the next buyer might pay 6.0x or higher.

Worked Example 3: Restaurant

A casual dining restaurant in a mid-size city has been operating for 12 years. The owner works 50 hours per week as the general manager. SDE is $150,000. Revenue has been flat for two years. The lease has 4 years remaining with a 5-year renewal option. No proprietary recipes or systems. Staff turnover is 60% annually.

This is a textbook lower-end restaurant deal. Heavy owner involvement, flat revenue, high turnover, and no competitive moat. The multiple sits at the bottom of the range.

  • SDE: $150,000
  • Multiple: 1.7x (lower end of 1.5x - 2.5x range)
  • Estimated Value: $150,000 x 1.7 = $255,000

At $255,000, the buyer is essentially buying a $150,000-per-year job with $255,000 in risk. The math only works if the buyer can increase revenue, reduce their own hours, or both. Many experienced acquisition buyers avoid restaurants entirely because of these thin margins and high failure rates.

How SBA Lenders Use Multiples

SBA lenders do not just accept whatever price buyer and seller agree on. They run their own valuation analysis, and industry multiples play a central role.

When you apply for an SBA 7(a) loan to acquire a business, the lender will calculate the business value using SDE multiples for the relevant industry. If the agreed purchase price is significantly above what the multiples suggest, the lender may require a third-party business valuation, reduce the loan amount, or decline the loan entirely.

Here is how this works in practice. You agree to buy an auto repair shop for $600,000. The SDE is $180,000. That implies a multiple of 3.33x. The typical range for auto repair is 2.0x to 3.0x. The lender sees that you are paying above market and flags the deal.

To get the loan approved, you would need to justify the premium. Maybe the shop has a long-term lease in a prime location, proprietary diagnostic equipment, or a fleet contract with the city. Without a compelling reason, the lender caps the loan at a value supported by industry multiples, and you cover the gap with additional cash or seller financing.

The lesson: know the multiples before you negotiate. If you are paying above the typical range, have a documented reason. If you are paying below, you likely have a stronger loan application. Check out our guide to SBA loans for business acquisitions for the full process.

Why Multiples Are a Starting Point, Not a Final Answer

Multiples give you a quick range to work with. They are not a precise valuation. Two HVAC companies with identical SDE can have dramatically different values based on recurring revenue, team strength, customer mix, and equipment condition.

Use multiples to screen deals quickly. If someone is asking 5.0x for a restaurant, you can immediately move on. If an IT services firm is listed at 3.5x with strong growth, it is worth investigating further.

Frequently Asked Questions

What is a good SDE multiple for a small business?

A "good" multiple depends on the industry and specific business characteristics. For most small businesses, multiples range from 1.5x to 4.0x SDE. Anything below 2.0x usually indicates higher risk or a less desirable industry. Multiples above 4.0x are typically reserved for SaaS, healthcare, and other businesses with strong recurring revenue or high barriers to entry. The best deal is not necessarily the lowest multiple - it is the one where the price is justified by the cash flow and risk profile.

How do I calculate the value of a small business?

Start by calculating the seller's discretionary earnings (SDE). This is net income plus the owner's salary, owner benefits, depreciation, amortization, interest, and non-recurring expenses. Then multiply SDE by the appropriate industry multiple from the table above. For example, a plumbing company with $250,000 in SDE at a 2.5x multiple is worth approximately $625,000. This does not include real estate or excess working capital, which are valued separately. Read our full guide on calculating SDE for step-by-step instructions.

What industries have the highest valuation multiples?

SaaS businesses command the highest multiples among small businesses, ranging from 4.0x to 8.0x SDE. This is driven by recurring revenue, high margins (often 70%+), and scalability without proportional cost increases. Healthcare and IT services also trade at premium multiples (3.0x to 5.0x) due to high barriers to entry, licensing requirements, and sticky customer relationships. Manufacturing sits in a similar range when the business has proprietary products or long-term contracts.

Do SDE multiples include real estate?

No. SDE multiples value the operating business only. Real estate is always valued separately, typically through a commercial appraisal or cap rate analysis. If the business owns its building, the deal is usually structured in one of two ways. Either the buyer purchases both the business and the real estate in a single transaction with separate valuations, or the seller retains the real estate and leases it to the buyer at market rate. The lease approach is more common in SBA-financed deals because it keeps the total transaction size manageable and the loan amount within SBA limits.
