What Is SDE? Seller’s Discretionary Earnings, Explained for Owners

TL;DR: Seller’s discretionary earnings, or SDE, is the number most small businesses are actually priced on when they sell. It starts with pretax profit, then adds back interest, taxes, depreciation, amortization, one working owner’s full compensation and benefits, and any non-recurring or personal expenses the business paid. In the first quarter of 2026, businesses under $500,000 sold for a median of 2.0 times SDE, and businesses between $1 million and $2 million sold for a median of 3.0 times SDE, per the IBBA and M&A Source Market Pulse survey. Get the SDE calculation wrong and every one of those multiples is being applied to the wrong number.

Ask a buyer what your business earns and they will not reach for the net income line on your tax return. They will rebuild the number themselves. In fifteen years of preparing businesses for sale across the Gulf South, I have never once sold a Main Street business on its tax-return profit. The number that gets multiplied, negotiated, and financed is seller’s discretionary earnings. Most owners have never calculated it. Many have never heard of it. That is a problem, because it is the single most important number in the sale of a business under about $2 million.

Key Takeaways

SDE measures the total economic benefit one working owner receives from the business: pretax profit plus interest, taxes, depreciation, amortization, one owner’s full compensation, and non-recurring or personal expenses.

Market convention prices deals under roughly $2 million in purchase price on SDE and larger deals on EBITDA, per the IBBA and M&A Source Market Pulse.

In Q1 2026, median multiples ran 2.0x SDE under $500K, 2.8x from $500K to $1M, and 3.0x from $1M to $2M.

Every add-back must be documented. An add-back you cannot prove is an add-back the buyer will not pay for.

What is seller’s discretionary earnings (SDE)?

Seller’s discretionary earnings is the standard measure of what a small business actually generates for one working owner. The International Business Brokers Association glossary defines discretionary earnings as “the earnings of a business enterprise prior to the following items: income taxes, non-operating income and expenses, nonrecurring income and expenses, depreciation and amortization, interest expense or income, one owner’s entire compensation, including benefits and any non-business or personal expenses paid by the business.”

Notice what that definition is doing. It strips out everything that reflects how the current owner chose to finance, structure, and run the company, and it isolates the cash the business would put in a new owner-operator’s pocket. You will also hear the same figure called discretionary earnings, owner benefit, or adjusted cash flow. They all point at the same idea.

Citation capsule: Seller’s discretionary earnings (SDE) is defined by the International Business Brokers Association as business earnings before income taxes, non-operating and non-recurring items, depreciation and amortization, interest, and one working owner’s entire compensation and benefits. It is the standard pricing metric for Main Street businesses, which the IBBA and M&A Source Market Pulse defines as deals under $2 million in purchase price.

Why does this metric exist at all? Because small-business tax returns are built to minimize taxable income, not to show a buyer what the business earns. SDE reverses that. It is the bridge between the return your CPA filed and the number a buyer will actually pay a multiple of. The mechanics of building that bridge are called recasting, and we cover the documentation side in detail in our guide to recasting financial statements.

What gets added back into SDE, and what does not?

Start with pretax net income, then add back items in four groups. The first three are mechanical. The fourth is where deals are won and lost.

Financing and tax items. Interest expense, income taxes. The buyer will have their own capital structure and their own tax situation.
Non-cash items. Depreciation and amortization.
One owner’s total compensation. Salary, payroll taxes on that salary, health insurance, retirement contributions. One owner, not two. If your spouse also draws a real salary for a real job, only one owner’s compensation comes back; the other position gets adjusted to a market-rate replacement wage.
Discretionary and non-recurring items. The personal vehicle, the family cell phone plan, the season tickets, the one-time lawsuit settlement, the hurricane deductible. Legitimate, provable, and clearly not required to run the business.

Here is a simplified example of what the bridge looks like for a service business:

Line item	Amount
Pretax net income per P&L	$180,000
+ Owner salary and payroll taxes	$95,000
+ Owner health insurance and retirement	$22,000
+ Interest expense	$14,000
+ Depreciation and amortization	$31,000
+ Personal vehicle and travel run through the business	$18,000
+ One-time equipment repair after storm damage	$12,000
Seller’s discretionary earnings	$372,000

The tax return says this owner earns $180,000. The market says the business generates $372,000 for its owner. At a 3.0x multiple, that difference is not academic. It is $576,000 of price.

What does not come back? Rent you actually pay, market-rate wages for employees who actually work, and any expense a new owner would still incur. And a warning from the other side of the table: buyers and their lenders scrutinize every add-back. The undocumented ones get struck first, and each struck add-back costs you its amount times the multiple.

SDE vs EBITDA: which number is your business priced on?

Purchase price decides it. The IBBA and M&A Source Market Pulse, the quarterly survey of Main Street and lower middle market transactions, reports deals under $2 million in purchase price as multiples of SDE and deals from $2 million to $50 million as multiples of EBITDA. The logic is simple. Below $2 million, the typical buyer is an individual who will step into the owner’s seat, so the metric assumes an owner-operator. Above it, buyers expect to hire management, so earnings are measured after a market-rate salary for a manager. That is the core difference: SDE includes one owner’s compensation as a benefit; EBITDA treats management pay as a cost.

The IBBA glossary separately defines the lower middle market as companies with $5 million to $50 million in annual revenue. If your business sits near the boundary, we quote both numbers, because the buyer pool determines the metric and businesses near the line draw both kinds of buyers. Our comparison of Main Street versus lower middle market valuation walks through that boundary in detail.

What do businesses actually sell for as a multiple of SDE?

In Q1 2026, the Market Pulse survey (56th edition, 203 completed transactions reported by roughly 300 advisors) put median multiples at 2.0 times SDE for businesses under $500,000, 2.8 times SDE from $500,000 to $1 million, and 3.0 times SDE from $1 million to $2 million. Larger deals from $2 million to $50 million ran a median of 4.0 times EBITDA. The pattern is durable across years of survey data: bigger businesses earn bigger multiples, because they are less dependent on any one person, customer, or piece of luck.

Two more Q1 2026 data points worth knowing. Sellers in these bands received most of their price in cash at close: 89 percent for deals under $500,000, 79 percent from $500,000 to $1 million, and 86 percent from $1 million to $2 million. And competition is real at the top of the market, where 83 percent of deals over $5 million attracted three or more offers. For the full multiple tables and what sits behind them, see what businesses actually sold for in 2026.

Our finding: In our own Gulf South engagements, the SDE recast moves the earnings number far more than owners expect. It is common for documented SDE to land 50 to 100 percent above tax-return net income for an owner-operated business. The owners who benefit are the ones whose add-backs survive diligence, and the ones whose add-backs survive are the ones with receipts.

The number honest sellers don’t believe

A composite from our practice, details changed to protect confidentiality. In fifteen-plus years of this work, I can count on one hand the owners who walked in already understanding seller’s discretionary earnings. The pattern repeats itself. An owner sits across the desk from me convinced the tax return tells the whole story. Then I come back with the recast number after all the add-backs, and I watch the surprise cross their face. The number is often half again what they believed the business earned, sometimes more.

Here is the part that surprises people who have never sat in that chair: the most honest sellers start backpedaling. They hear their own SDE and their first instinct is to argue it down. They tell me they do not want to do anything that misrepresents the business, because they do not believe their own profitability once the add-backs are in. I have that conversation over and over, and my answer is always the same. This is a normal, standard part of business valuation, and it is ethical and completely above board. Add-backs are not spin. They measure the full economic benefit the owner actually takes from the business, which is exactly what the next owner is buying.

What that instinct gets right is that the number has to be earned. A big part of establishing SDE is establishing the credibility it takes to support that SDE through due diligence, especially when a bank or a professional buyer is involved. Every add-back tied to a general ledger line, an invoice, or a payroll record, assembled so the lender can underwrite it without a follow-up question. Done right, the SDE calculation does more than survive scrutiny. It enhances our credibility with the buyer, because the front-end work behind it is so thorough that every number the buyer tests holds up, and that trust carries into every other claim we make for the rest of the deal. That is what my clients pay me for. Not a bigger number, a defensible one.

How do you calculate your own SDE?

You can get a credible first pass in an afternoon. Here is the sequence we use:

Pull three full years of P&Ls plus the trailing twelve months. Buyers weight recent performance; you should too.
Start from pretax net income, not from cash in the bank and not from taxable income after Section 179 games.
Add the mechanical items: interest, taxes, depreciation, amortization.
Add one owner’s complete compensation: salary, payroll taxes, health insurance, retirement match.
List every discretionary or one-time expense candidate, then keep only the ones you can document. Be honest here. One aggressive, indefensible add-back can poison a buyer’s trust in all the legitimate ones.
Normalize what is left: market rent if you own the building, replacement wages for family members, market pricing for related-party arrangements.

Would a buyer accept your number as it stands today? That is the real test. Our 10-minute self-assessment is a fast way to pressure-test where you stand, and the complete owner’s guide to business valuation explains how SDE feeds the formal valuation approaches.

Seller’s Discretionary Earnings FAQ

What does SDE stand for in business?

SDE stands for seller’s discretionary earnings. It measures the total economic benefit a business provides to one full-time working owner: pretax profit plus interest, taxes, depreciation, amortization, one owner’s entire compensation and benefits, and documented non-recurring or personal expenses. It is the standard earnings metric for pricing owner-operated businesses.

What is the difference between SDE and EBITDA?

SDE adds back one working owner’s entire compensation because it assumes the buyer will replace the owner in the business. EBITDA does not; it treats management pay as an operating cost. The IBBA and M&A Source Market Pulse quotes deals under $2 million in purchase price on SDE and deals from $2 million to $50 million on EBITDA.

What is a typical SDE multiple in 2026?

Per the Q1 2026 IBBA and M&A Source Market Pulse, median multiples were 2.0 times SDE for businesses selling under $500,000, 2.8 times SDE from $500,000 to $1 million, and 3.0 times SDE from $1 million to $2 million. Industry, growth, transferability, and documentation quality move individual businesses above or below those medians.

Does SDE include the owner’s salary?

Yes. One working owner’s full compensation package, including salary, payroll taxes, health insurance, and retirement contributions, is added back into SDE. Only one owner’s compensation comes back; additional working family members are adjusted to the market wage a new owner would pay to replace them.

What add-backs do buyers reject?

Buyers and their lenders reject add-backs that lack documentation, expenses a new owner would still incur, recurring items dressed up as one-time costs, and aggressive personal-expense claims with no paper trail. Each rejected add-back reduces the price by that amount times the multiple, which is why we document every line before going to market.

Conclusion: the multiple gets the attention, the SDE earns the money

Owners love to talk about multiples. But the multiple is set mostly by your size and industry. The number you control is the one it gets multiplied against. Clean books, documented add-backs, and a defensible recast routinely move the outcome more than a half-turn of multiple ever will.

If you want to know what your SDE actually is, with every add-back documented the way a buyer’s lender will demand, that is exactly the work we do before any business goes to market. Book a free consultation and we will walk through your P&L together.
