SDE (Seller's Discretionary Earnings): What It Means for Business Buyers

What Is SDE?

SDE stands for Seller's Discretionary Earnings. It is the most common valuation metric used in small business sales, typically for companies under $5M in revenue.

The formula is straightforward:

SDE = Net Income + Owner Salary + Owner Benefits + Discretionary Add-Backs + One-Time Expenses

The logic behind it: a single owner-operator receives economic value from the business in multiple forms. Their W-2 salary is one layer. But they might also pay for a personal vehicle, a cell phone, health insurance, travel, or other expenses through the business. SDE adds all of that back to net income to show the full economic picture.

That part is legitimate.

The problem is what happens next.

How Brokers Use SDE to Their Advantage

Brokers use SDE because it produces the largest defensible number. Larger number means higher asking price. Higher asking price means a larger commission.

This is not a conspiracy. It is how the market works. A buyer needs to understand it going in.

Here is where it gets slippery. Add-backs are supposed to be real, documented, and non-recurring. In practice, brokers push the definition. "Owner meals" becomes a $30K add-back. A one-time equipment repair becomes an add-back. A family member on payroll who did actually do some work gets added back in full.

By the time the broker is done, the SDE looks significantly healthier than the business actually is.

The Critical Difference: SDE vs. What a Buyer Actually Earns

When you buy a business, you step into the operator role. That changes the math in two ways.

First, if you are replacing a working owner, you need to pay yourself a market-rate salary. That salary does not go in your pocket twice. It comes out of cash flow before debt service.

Second, some of the add-backs were genuinely personal to the seller. That $1,800/month personal vehicle lease does not follow the business to new ownership. The add-back disappears.

Third, SDE ignores debt service entirely. It tells you what the business earns. It does not tell you what is left after you pay the bank.

A business showing $300K SDE might produce $180K in real after-salary, after-debt-service cash flow. Or less.

Based on Regalis Capital's analysis of recent acquisitions, buyers who underwrote deals on SDE without adjustment consistently found 15% to 50% less actual cash flow than the broker's headline number suggested.

That gap is the difference between a deal that works and one that puts you underwater.

How to Calculate SDE: A Worked Example

Take a $200K SDE business. Here is how the broker likely built that number, and how a buyer should restate it.

These figures are a realistic hypothetical illustration, not a specific closed deal.

The broker is not wrong that SDE is $223K. The add-backs are documented. But a buyer paying 3x SDE ($669K asking price) is actually paying roughly 6x real adjusted cash flow. That deal may not clear a 1.5x DSCR, let alone the 2x target Regalis uses.

These are rough estimates for illustrative purposes. Actual deal economics depend on individual business financials and lender underwriting.

SDE vs. EBITDA: What Is the Difference?

EBITDA (Earnings Before Interest, Taxes, Depreciation, and Amortization) is used for larger businesses, typically above $3M to $5M in revenue. It does not add back the owner's salary, because larger companies have management teams in place and do not depend on a single owner-operator.

SDE is used for smaller, owner-operated businesses where the owner's economic benefit is the central valuation driver.

The practical difference: a business with $300K SDE and a $150K owner salary might show $150K EBITDA. Same business. Very different headline number.

SBA lenders use their own underwriting standard, which typically looks at business cash flow after a replacement management cost, before debt service. This number is often called "cash flow available for debt service" and it sits between EBITDA and raw SDE.

When Regalis underwrites a deal, we always recast SDE to an adjusted number before running debt service coverage calculations.

How SDE Affects SBA Loan Sizing

SBA lenders do not lend against SDE directly. They lend against verified, tax-return-supported cash flow, adjusted for debt service capacity.

If a broker is showing $300K SDE but the business tax returns show $180K in net income plus $80K owner salary, a lender will work from the tax return numbers, not the broker's add-back schedule.

This is one of the most common disconnects in small business deals. A buyer gets excited about a $300K SDE number, locks in a purchase price, then discovers lender underwriting comes in 30% lower than the broker's package suggested.

The result: the deal does not qualify for the loan amount needed to close at the agreed price.

As of Q1 2026, SBA lenders are scrutinizing add-backs more carefully than in prior years. One-time add-backs need documentation. Owner salary add-backs need a clear replacement cost analysis. Lenders are asking for 2 to 3 years of business tax returns, not just a broker-prepared cash flow recast.

Frequently Asked Questions

What is a typical SDE multiple for a small business acquisition?

As of Q1 2026, most small businesses with under $1M SDE trade between 2x and 4x SDE, depending on industry, size, and growth trajectory. Service businesses with recurring revenue tend to trade at the higher end. Retail or single-location food businesses often trade at 2x or below. The multiple is only meaningful after you have restated SDE to a real, buyer-adjusted cash flow figure.

How much should I discount SDE when evaluating a deal?

Regalis Capital's deal team applies a 15% to 50% discount to broker-reported SDE before underwriting debt service coverage. The right discount depends on how aggressive the add-backs are, whether a replacement salary is needed, and how many add-backs are genuinely non-recurring. A deal with clean, documented add-backs and a seller who stayed lean on personal expenses might only need a 15% haircut. A deal with heavy personal expense mixing might need 40% or more.

Do SBA lenders use SDE to approve loans?

No. SBA lenders use adjusted business cash flow supported by tax returns, not broker-prepared SDE schedules. Lenders will verify income through 2 to 3 years of federal business tax returns and run their own cash flow analysis. Add-backs that are not reflected on tax documents face heavy scrutiny. This is why a deal that looks strong on SDE can still fail to qualify for the loan amount needed to close at the agreed-upon price.

Buying a Business and Not Sure If the SDE Is Real?

This is one of the most common places deals go sideways. A broker's SDE figure looks strong. The asking price feels justified. Then lender underwriting comes back at 70 cents on the dollar and the deal falls apart.

Regalis Capital's deal team reviews 120 to 150 deals per week and recasts cash flow on every single one before we let a client go to LOI. If you are evaluating a business and want a second set of eyes on the numbers, start with a free deal assessment.
