How to Value a Small Business for Sale

Your broker told you the business is worth $1.8M. A buyer’s advisor runs the numbers through SBA underwriting and lands at $1.2M. That is not a lowball. That is the real number, backed by the math a lender will actually approve.

Learning how to value a small business for sale means setting aside what feels right and looking at what the cash flow supports. What the debt service allows. What a lender signs off on. Sellers who understand this close faster and with fewer surprises. Sellers who do not end up relisting six months later after a deal collapses in diligence.

Here is how the calculation actually works from the buy side.

What “Value” Actually Means When a Business Changes Hands

Most sellers anchor to a gut-feel number tied to revenue or years in operation. Buyers see it differently. Value is a function of one thing: how much transferable cash flow does this business produce, and what multiple does the market pay for it.

Two metrics drive almost every small business valuation below $5M.

Seller Discretionary Earnings (SDE) is the standard for businesses with one owner-operator. Start with net income, add back the owner’s salary, personal expenses run through the business, depreciation, amortization, and one-time costs. The result represents the total economic benefit a new owner would receive.

EBITDA applies to larger businesses or those with a hired management team already running operations. It stands for Earnings Before Interest, Taxes, Depreciation, and Amortization. Because it does not include an owner add-back, EBITDA tends to come in lower than SDE for the same business.

The multiple applied to either metric reflects industry norms, deal risk, and current market conditions. For SDE, most small business deals close between 2.0x and 3.0x. The ceiling we underwrite to is 3.5x. For EBITDA, the range is typically 2.5x to 4.0x, with a hard cap at 5.0x for deals at the quality end of the market.

Revenue is almost never the right basis for valuation. Sellers anchor to it. Buyers ignore it.

The SBA Underwriting Test: The Real Floor on Valuation

Here is something most sellers never hear from their broker: the buyer’s lender has more influence over your final sale price than the buyer does.

When a buyer uses SBA 7(a) financing (which is the standard financing tool for acquisitions under $5M, and the one most buyers in this range end up using), the lender runs a Debt Service Coverage Ratio calculation before approving the loan. That DSCR number determines whether the deal is fundable at a given price. Not the broker’s opinion. Not the buyer’s enthusiasm. The ratio.

DSCR is straightforward. Take the business’s annual SDE or EBITDA and divide it by the annual debt payments the acquisition loan generates. We target a minimum 2.0x DSCR. The SBA typically requires 1.25x at a bare minimum, but anything below 1.5x is dangerous territory.

Here is how that plays out in practice.

Say you are selling a landscaping company with $280K in SDE. A buyer offers $840K, which is 3.0x SDE. On a 10-year SBA loan at current rates, the annual debt service on $840K runs roughly $105K to $115K. That generates a DSCR somewhere around 2.4x to 2.7x. Clean deal. Everybody moves forward.

Now say the broker listed it at $1.2M (4.3x SDE). The debt service jumps to approximately $150K to $160K per year. DSCR falls to about 1.75x. The lender pulls back. The deal either dies or the buyer renegotiates the price down to where the arithmetic works. And the seller, who spent 90 days in diligence thinking they had a done deal, is back to square one.

The DSCR test is why valuation multiples have a ceiling. Not arbitrary. Arithmetic.

How to Calculate SDE (And Why Your Number Is Probably Off)

Getting the SDE calculation right is the single most important thing a seller can do before listing. An inflated SDE creates offers that collapse in due diligence. An understated SDE leaves money on the table. Both are avoidable.

SDE calculation follows this sequence:

Start with net income from your most recent full-year tax return (or a 3-year average weighted toward recent years).
Add back your W-2 salary and any personal health insurance paid by the business.
Add back personal expenses the business paid that a new owner would not incur: auto, phone, travel, meals with a legitimate add-back case.
Add back depreciation and amortization.
Add back any one-time or non-recurring expenses. Legal fees from a one-off dispute, equipment that was replaced and will not recur, COVID-related losses in specific years.
Remove any above-market rent if you own the real estate. Normalize it to market rate so a buyer understands the real occupancy cost.

Side note: step 6 catches a lot of sellers off guard. If you own both the business and the building, the rent you charge the business may not reflect what a third-party tenant would actually pay. Lenders and buyers will normalize this, so you should do it first.

A few add-backs buyers will push back on: family members on payroll who do real work and whose roles a buyer would need to hire for, owner’s discretionary travel that is genuinely business-critical, and equipment expenses that recur annually even if the amounts vary.

Every add-back you claim will be scrutinized. Clean, documented add-backs hold up. Questionable ones get stripped out, and the valuation adjusts with them.

What Drives a Higher Multiple

Two businesses with the same SDE can command very different prices. The variables that push toward the higher end of a range are worth understanding before you enter negotiations.

Recurring revenue. A business where 60% of revenue comes from contracts or subscriptions gets a higher multiple than one that restarts from zero each month. Buyers pay a premium for predictability.

Low owner dependency. If the business runs when you are not there, it is worth more. If you are the key relationship, the primary technician, or the only person who knows how things work, buyers discount heavily for key-person risk.

Customer concentration. If one customer represents more than 20% of revenue, expect the buyer to either lower the offer or structure an earnout tied to that customer’s retention. We see concentration kill more deals than almost any other single factor.

Clean financials. Three years of tax returns that tell a consistent story, a clear P&L, and documented add-backs reduce perceived risk. Messy books signal risk to buyers and lenders alike.

Strong DSCR. Valuations that work at the DSCR level close. Ones that do not, do not. No amount of negotiation changes this.

Industry matters too. Service businesses with low capex, trained workforces, and established customer lists tend to trade at the higher end. Industries with high equipment replacement costs, regulatory risk, or cyclical revenue trade lower.

And What Kills It

This part is shorter because it is simpler.

Buyer dependency on the owner, messy or inconsistent financials, customer concentration above 20%, declining revenue trends, and a listing price that does not clear the DSCR test. Any one of these can compress your multiple from 3.0x down to 2.0x, or kill the deal outright.

You would be surprised how many sellers come to market with two or three of these issues running simultaneously and wonder why qualified offers are not materializing.

SDE Multiple vs. EBITDA Multiple: Which One Applies

This is a common source of confusion. Using the wrong metric, or applying the wrong multiple to the right metric, leads to expectations that are significantly out of line with what buyers will pay.

Use SDE if: You are an owner-operator with one primary owner running the business. Most businesses under $1.5M in cash flow fall here. SDE is the right metric when the owner’s compensation is part of what the buyer is replacing or adjusting.

Use EBITDA if: Your business already has a management layer in place and the owner is not actively working in day-to-day operations. Larger businesses (generally those with revenue above $3M to $5M) and businesses being sold to a buyer who plans to install a general manager tend to be valued on EBITDA.

A common and costly error: applying an EBITDA multiple (say 4.0x) to an SDE number ($400K) to get a $1.6M valuation, when the business really warrants a 2.5x to 3.0x SDE multiple for a $1.0M to $1.2M asking price. That $400K gap is not a negotiating position. It is a structural misunderstanding that kills deals before they start.

If your broker is mixing these up, correct it before the listing goes live. Not after you have burned through three months of buyer interest.

So That Covers the Valuation Side. The Structure Side Is Different.

Valuation and price are not the same as what you walk away with at closing.

Most SBA-financed acquisitions below $5M close with a structure that looks roughly like this: 70% to 85% SBA loan, 10% to 15% buyer equity injection, and a seller note covering the remainder. The seller note is typically put on full standby for up to 10 years at 0% interest. Zero interest. Zero payments. For the duration of the standby period.

This is standard. Not a red flag. We see this structure on over 90% of the SBA deals we work on. It is how the SBA deal math works, and sellers who understand it going in negotiate more effectively than those who learn about it mid-deal.

What this means for you in practice: if the deal closes at $1.2M and includes a $120K seller note, you receive $1.08M at closing and $120K over time (or in a lump sum if the buyer refinances). Your CPA should walk through the tax treatment carefully, because the timing and character of proceeds can have a meaningful impact on what you net after taxes.

Asset sales versus stock sales also affect net proceeds. Most SBA-financed acquisitions are structured as asset sales (per SBA Standard Operating Procedures, this is the typical requirement). The tax treatment differs significantly for sellers, so model both structures before agreeing to terms.

What Regalis-Backed Buyers Look Like From the Seller’s Side

Sellers sometimes wonder what it means when a buyer shows up with an advisory team already in place. Here is the practical answer.

Our buyers come pre-underwritten. We have reviewed the deal, run the DSCR, confirmed SBA eligibility, and structured the offer before it reaches the seller. That means less time wasted on buyers who cannot actually close, and fewer deals that fall apart mid-diligence because the financing was never real.

There is no cost to sellers in any deal we work on. We represent the buyer. The seller has zero fees, no commissions, and no obligation.

We review 120 to 150 deals per week. We know which businesses close and which sit. The sellers who close faster are almost always the ones who come in with clean books, realistic expectations about how to value a small business for sale, and a willingness to structure the deal in a way that works for SBA financing. From what we have seen across hundreds of deals, those three things matter more than the listing price itself.

Frequently Asked Questions

How do I value a small business for sale using SDE?

Calculate seller’s discretionary earnings by adding back the owner’s salary, personal expenses, depreciation, and non-recurring costs to net income. Then apply a market multiple. Most small businesses below $5M sell at 2.0x to 3.0x SDE. The right multiple depends on industry, recurring revenue, owner dependency, and whether the deal works at an acceptable DSCR for SBA financing.

What is a realistic sale price for a small business doing $500K in revenue?

Revenue alone does not determine price. What matters is cash flow. A $500K revenue business might produce $120K in SDE or $200K depending on margins and owner expenses. At 2.5x SDE, those businesses sell for $300K or $500K respectively. Buyers and lenders underwrite cash flow, not revenue, so focus on cleaning up and documenting your SDE before setting price expectations.

How long does it take to sell a small business using SBA financing?

From a signed letter of intent to closing, SBA-financed business sales typically take 60 to 90 days. This includes 30 to 45 days of buyer due diligence and 2 to 4 weeks of SBA lender underwriting. Deals move faster when the seller’s financial records are organized and the buyer’s advisory team has experience with the SBA process.

Why do buyers use a DSCR calculation when valuing a business?

The DSCR tells the lender whether the business generates enough cash flow to service the acquisition loan. SBA lenders require a minimum of 1.25x DSCR. Buyers and advisors typically target 2.0x or higher for deal viability. If the asking price produces a DSCR below the lender’s threshold, the deal either reprices or falls apart. Valuation multiples have a practical ceiling tied to cash flow, not just market sentiment.

What is the difference between an asset sale and a stock sale for a small business?

In an asset sale, the buyer purchases specific business assets (equipment, customer lists, contracts, goodwill) rather than the legal entity. In a stock sale, the buyer acquires the entire company including its liabilities and legal history. Most SBA-financed small business acquisitions are structured as asset sales. The tax treatment differs significantly for sellers, so your CPA should model both structures before you agree to deal terms.
