What Is an SDE Multiple—and What Multiple Should You Pay?
Understand how SDE multiples work, why industry averages are only a starting point, and what can make two similar businesses deserve different prices.
# What Is an SDE Multiple—and What Multiple Should You Pay?
An SDE multiple compares the price of a business with its seller’s discretionary earnings.
The math is almost suspiciously simple:
Price ÷ SDE = SDE multiple
If a business is priced at $600,000 and reports $200,000 of SDE, the asking multiple is 3.0×.
Simple calculation. Complicated conclusion.
What the multiple actually tells you
A multiple is a compact way to describe how expensive a business is relative to one year of reported owner earnings.
It helps you:
- Compare asking prices across similar businesses
- Notice unusually high or low pricing
- Translate changes in SDE into potential changes in value
- Speak the same general language as brokers, lenders, and valuation professionals
It does not tell you that you will recover your cash in exactly three years. Loan payments, taxes, equipment, working capital, growth, declines, and the accuracy of SDE all remain stubbornly present.
Why there is no universal “right multiple”
Buyers often ask for the normal multiple as if every business is a can of soup with a shelf price.
Market data can provide a range, but the appropriate multiple depends on the business and the evidence behind it.
Factors that may support a higher multiple include:
- Stable or growing supported earnings
- Recurring or repeat revenue
- Low customer concentration
- A capable team that can remain after closing
- Documented systems and limited owner dependence
- Transferable contracts, leases, licenses, and supplier relationships
- Equipment in good condition
- A long operating history
Factors that may support a lower multiple include:
- Declining or volatile earnings
- Heavy reliance on one customer, employee, supplier, platform, or owner
- Questionable add-backs
- Short lease term or difficult assignment
- Major deferred maintenance
- Weak records
- Unusual regulatory, litigation, or transition risk
The multiple is where the market’s opinion about quality and risk meets the earnings figure.
Compare the right businesses
A 3× multiple for a landscaping company is not automatically comparable with a 3× multiple for a subscription software company.
Industry matters. Size matters. Geography may matter. Real estate matters. The measurement period matters. Whether the data reflects asking prices or completed sales matters.
When reviewing market data, ask:
- Are these asking prices or actual sale prices?
- Are the earnings seller-reported or independently verified?
- What dates does the data cover?
- How many transactions are included?
- Does the price include inventory or real estate?
- Are the compared businesses similar in size and operating model?
A precise-looking average built from the wrong comparison group is still the wrong answer. It is simply wearing a tie.
The multiple amplifies SDE mistakes
Suppose a listing claims:
- Asking price: $750,000
- Reported SDE: $250,000
- Asking multiple: 3.0×
After reviewing the records, you conclude that $40,000 of add-backs are unsupported. Adjusted SDE becomes $210,000.
The asking price is now approximately 3.57× your supported SDE—not 3.0×.
Nothing about the price changed. Your understanding did.
That is why the quality of SDE deserves attention before debating whether 2.8× or 3.1× is fair.
Price and financeability are different questions
A business can be reasonably priced compared with similar sales and still fail to support the proposed debt.
It can also support debt while being expensive relative to its risk.
Use at least two screens:
- Market screen: How does the price compare with supported earnings and relevant transactions?
- Cash-flow screen: After realistic expenses, can the business pay the acquisition debt and leave enough room for the owner and normal volatility?
The multiple helps with the first question. DSCR and cash-flow modeling help with the second.
So, what multiple should you pay?
There is no responsible one-number answer without knowing the business, verified earnings, included assets, market evidence, financing, and risks.
A better process is:
- Calculate the multiple using seller-reported SDE.
- Recalculate it using supported SDE.
- Review relevant sold-business and listing data separately.
- Adjust your expectations for concentration, owner dependence, growth, equipment, contracts, and transition risk.
- Test whether the resulting price works under realistic financing and downside assumptions.
- Obtain professional valuation support when the decision or transaction warrants it.
The bottom line
An SDE multiple is a comparison tool, not a valuation certificate.
Use it to notice when the price and earnings appear out of alignment. Then investigate why. Sometimes the business deserves a premium. Sometimes the listing is optimistic. Sometimes the SDE is doing gymnastics.
The number starts the conversation. The evidence decides how seriously to take it.
