Seller’s discretionary earnings (SDE) is the total pre-tax financial benefit a single full-time owner-operator takes out of a business in a year, expressed as one number. It starts with pre-tax net income and adds back the owner’s compensation, interest, depreciation and amortization, and the personal or one-time expenses that will not continue under new ownership. Buyers of smaller owner-operated companies price on SDE because it answers the question they care about: if I run this business myself, how much cash is available to pay myself and service acquisition debt?

What Seller’s Discretionary Earnings Measures
The one-owner convention
SDE assumes exactly one working owner. That owner’s full compensation package comes back into earnings, because the buyer is stepping into the seat and will decide what to draw. If a business has two or three owners on payroll, only one seat is added back in full. The others are treated as employees: their pay stays as an expense, or is replaced at a market wage if they were overpaid for the job they do.
This is where inflated SDE figures usually start. An owner and spouse each drawing $150,000 for two genuine full-time roles produces one add-back, not two. Getting it wrong means repricing the deal later, the most expensive thing that can happen in a sale process.
Why the metric exists
Owner-operated financials are not built to show profitability. They are built to minimize tax. Discretionary spending, family payroll and accelerated depreciation suppress reported net income, so the business looks far less profitable on paper than it is. SDE undoes that distortion so the operation can be compared against other businesses a buyer is considering.
What SDE is not
SDE is not free cash flow, and it is not what a buyer ends up with. It sits above capital expenditures, working capital, income taxes and debt service. A business with $1 million of SDE that needs $200,000 a year of equipment replacement does not deliver $1 million of spendable cash. Every experienced buyer and lender adjusts for this.
The SDE Formula and Standard Add-Backs
The formula
SDE = pre-tax net income + one owner’s total compensation + interest expense + depreciation and amortization + discretionary personal expenses + non-recurring items. Each term should trace to a line on the tax return or general ledger. Building this schedule is called recasting, and the output should be a document a buyer’s accountant can walk through line by line.
Add-backs buyers accept with little argument
- The owner’s W-2 salary, compensatory distributions, and employer payroll taxes on that salary. These come back in full because the buyer sets their own pay.
- Owner health, life and disability premiums and retirement contributions made for the owner personally. These belong to the compensation package, not to the cost of operating.
- Interest expense on company debt, since the buyer will carry a different capital structure and the seller’s borrowing says nothing about operating performance.
- Depreciation and amortization, since these are non-cash charges. Expect an offsetting conversation about maintenance capital expenditures in asset-heavy businesses.
- A personal vehicle used mainly outside the business, including lease, fuel and insurance, where it is not required to deliver the service.
- Genuinely one-time costs such as a settled lawsuit or a flood repair, provided there is documentation showing the event closed and will not recur.
Add-backs buyers push back on
- Meals, entertainment and travel. Buyers routinely accept a fraction of what is claimed, reasoning that some of that spending genuinely supports customer relationships and will continue.
- Family members on payroll who actually work. If a spouse handles the books eight hours a week, only the amount above a market wage for that work qualifies.
- Above-market rent paid to a building the owner holds separately. Buyers usually want the lease restated at market as a closing condition rather than taking the add-back on faith.
- Failed initiatives such as a marketing campaign that did not work. Buyers treat experimentation as a recurring cost of running a business, not an anomaly.
- Large blocks of perks such as club memberships and season tickets. Past a modest amount these stop reading as add-backs and start reading as a signal about the books being loose.
- Depreciation in equipment-intensive businesses. The charge is non-cash, but the replacement spending behind it is real, and buyers will size a capital reserve against it.
A Worked SDE Add-Back Schedule
The schedule as the seller presents it
Take an HVAC contractor with $6,200,000 of revenue and $412,000 of pre-tax net income on its most recent return. The owner runs the company full time. The building is held by the owner’s LLC and leased to the business at $216,000 a year against a $174,000 market rent.
| Pre-tax net income | $412,000 |
| Owner W-2 salary | $185,000 |
| Employer payroll taxes on owner salary | $14,150 |
| Owner health and life insurance | $28,400 |
| Interest expense | $63,000 |
| Depreciation and amortization | $148,000 |
| Owner personal vehicle and fuel | $19,600 |
| Spouse on payroll | $52,000 |
| One-time legal settlement | $76,000 |
| Personal travel and club dues | $22,500 |
| Above-market related-party rent | $42,000 |
| Total add-backs | $650,650 |
| Seller’s discretionary earnings | $1,062,650 |
What survives diligence
Two lines get trimmed. The spouse genuinely handles bookkeeping about eight hours a week and a replacement costs $24,000, so only $28,000 of the $52,000 is a real add-back. Travel and club dues fall from $22,500 to $9,000 once the buyer finds recurring customer entertainment inside the total. The combined $37,500 reduction brings defensible SDE to $1,025,150.
The rent add-back survives only because the seller agrees to restate the lease at $174,000 at closing. Depreciation survives too, while the buyer separately underwrites roughly $110,000 a year of truck replacement. That reserve does not reduce SDE; it shows up in the multiple and in how the lender sizes the loan.
SDE Compared With EBITDA and Net Income
How the three relate
Net income is what the tax return reports after every expense, including owner pay. EBITDA removes interest, taxes, depreciation and amortization but leaves management compensation as an operating cost, because an institutional buyer pays someone to run the company. SDE goes further and removes one owner’s compensation entirely. For the same company, SDE is always largest and net income smallest.
Converting SDE to adjusted EBITDA
The bridge between them is the cost of replacing the owner. Subtract a market compensation package for whoever would do the owner’s job and SDE becomes adjusted EBITDA. In the example above, a general manager capable of running the company costs $178,000 fully loaded, so adjusted EBITDA is $847,150 against SDE of $1,025,150.
This is why one business can be quoted at two multiples and one price. At 4.0 times SDE it is worth $4,100,600, and that same figure is 4.8 times adjusted EBITDA. Neither is more correct; they apply to different earnings bases. Comparing an SDE multiple to an EBITDA multiple without converting is the most common valuation error owners make.
Where the convention switches
The switch tracks buyer type more than company size. Individuals and searchers who will personally operate the business think in SDE. Private equity groups and strategic acquirers who install or retain management think in EBITDA. In practice, transactions below roughly $2 million of enterprise value are quoted on SDE and deals above $5 million on EBITDA, with both appearing in between.
SDE Multiples and How Buyers Apply Them
Multiples by size
Larger earnings streams command higher multiples, and the pattern is consistent across broker surveys of completed transactions. Recent quarterly survey data from business brokerage and M&A trade associations has shown median multiples around six times SDE for businesses selling under $500,000, roughly five times in the $500,000 to $1 million band, and about four and a half times between $1 million and $2 million. Above $2 million those same surveys switch to EBITDA and report medians near four times.
Multiples by business type
Marketplace data covering thousands of completed small-business sales shows sector averages clustering between roughly two and three and a half times SDE. Restaurants and owner-dependent retail sit near the low end. Trade services, healthcare practices and construction land in the mid-two range. Manufacturing, distribution and technology-enabled businesses average above three. Because that data skews toward sub-$1 million deals, a well-run lower-middle-market business typically prices above its sector average.
What actually moves the multiple
Within any sector and size band the spread is wide, and it is driven by risk rather than by the earnings number. Owner dependence is the biggest single factor: a business where the owner holds the customer relationships and approves every decision is worth materially less than the same earnings produced by a management team. Customer concentration, recurring versus project revenue, record quality and the direction of earnings fill in the rest.
How SDE Is Used in Small-Business Lending
The lender’s version of the number
When a buyer finances an acquisition with an SBA 7(a) loan, the lender rebuilds SDE from the tax returns rather than accepting the seller’s recast. The test is whether each add-back is documented and represents a cost that genuinely disappears under new ownership. Because loan size is driven by cash flow, every dollar that fails reduces what a buyer can borrow and therefore pay.
Debt service coverage and the buyer’s salary
The lender takes verified SDE, subtracts a living wage for the buyer and a capital expenditure allowance, then divides the remainder by annual debt service. Most SBA lenders want that ratio at 1.15 to 1.25 or better on historical earnings. Program rules require a minimum ten percent equity injection on a change of ownership, and a seller note on full standby can supply no more than half.
Coverage math therefore sets a ceiling on price in the SBA-financed market. A business whose defensible earnings will not cover debt service at the asking price will not close with a leveraged buyer, whatever the recast says.
Quality of earnings on larger transactions
Current SBA rules require an independent quality of earnings report on acquisition loans at or above a $3 million purchase price, measured before buyer equity or seller financing. The report tests the schedule item by item, and the lender must underwrite to the earnings it supports. Sellers in that range should assume every discretionary line will be examined by a third party with no stake in closing.
Frequently Asked Questions
What is a good SDE multiple for a small business?
A good SDE multiple for a small business is generally two to three and a half times for sub-$1 million transactions, rising toward four to five times as SDE approaches and exceeds $1 million. Sector, owner dependence and earnings quality move a specific business within that range.
Is SDE the same as cash flow?
SDE is not the same as cash flow, though listings often use the terms interchangeably. SDE sits above capital expenditures, working capital changes, income taxes and debt service. Actual cash available to an owner after those items is usually well below the SDE figure quoted in a marketing package.
Can I add back my spouse’s salary?
You can add back a spouse’s salary only to the extent it exceeds the market cost of replacing the work they actually do. If a spouse performs no operating role, the full amount qualifies. If they run the books, only the excess above a market wage does.
Does SDE include the owner’s health insurance?
Yes, SDE includes the owner’s health insurance along with life and disability premiums and retirement contributions made on the owner’s behalf. These are components of the owner’s compensation package rather than costs of operating the business, so they come back into earnings with the salary.
At what size do buyers stop using SDE?
Buyers generally stop using SDE once a transaction exceeds roughly $5 million in enterprise value, because acquirers at that level install professional management and think in EBITDA. Below about $2 million, SDE is effectively universal. Between those figures both metrics appear, depending on who is bidding.
How do buyers verify SDE?
Buyers verify SDE by tracing every add-back to source documents: tax returns, payroll registers, the general ledger, credit card statements, leases and settlement paperwork. Anything supported only by the seller’s explanation is removed. On larger deals an independent accounting firm performs this work.
Verification usually happens after a letter of intent is signed, which is the worst time to discover a problem. Sellers who document the schedule before going to market avoid the retrade that follows when add-backs fail.
Working With an M&A Advisor on Your SDE
The value of an advisor here is not producing a bigger number. It is producing a number that holds. A sell-side advisor builds the recast the way a buyer’s accountant or a lender’s quality of earnings provider will read it, with a source document behind each line, and removes the marginal items that invite scrutiny of the whole schedule. A defensible $1,025,000 of SDE closes at a higher price than an aggressive $1,180,000 cut in diligence, because the second costs both dollars and credibility where leverage matters most.
An advisor also frames the number for the right audience, so the same company presented on SDE to an individual buyer and on adjusted EBITDA to a private equity group prices consistently. Beyond the arithmetic, the work is identifying which risk factors suppress the multiple and whether any can be fixed in the year or two before a sale. Reducing owner dependence moves value more than any add-back will.
SDE is the earnings base; the multiple applied to it comes from somewhere else. That multiple is normally derived through comparable company analysis, and where a buyer wants to test the number against projected cash flow rather than market pricing, the alternative is a discounted cash flow valuation.
