SDE vs EBITDA: Which One Buyers Actually Use
The short answer
Buyers use SDE for owner-operated businesses, usually under about $5 million in revenue, because it counts one owner's pay as profit. They switch to EBITDA once a business has a management team running it without the owner. The two measure different things, so a multiple from one world can never be applied to a number from the other without recalculating the whole deal.

What SDE actually is
SDE stands for seller's discretionary earnings. It is the total financial benefit one full-time owner-operator gets from the business in a year. Start with the pretax net profit on the tax return or P&L, then add back the owner's salary, the owner's payroll taxes on that salary, and any personal expenses the business paid for that a new owner would not need to keep paying. Add back interest expense, depreciation, and amortization too, since those relate to how the current owner financed and depreciated assets, not how the business actually performs day to day.
The idea behind SDE is simple: it answers the question a buyer who plans to run the business themselves is really asking, which is what will this business pay me if I step into the owner's chair. That is why it only adds back one owner's compensation. If two owners both draw salaries from the business, only one of those salaries gets added back as discretionary; the other is treated as a real cost of running the place, because someone still has to do that job.
SDE is the standard yardstick for small, owner-operated businesses, and it is what most buyers of a Main Street business, from a landscaping company to a small medical practice, will calculate first before they even ask you what multiple you have in mind.
What EBITDA actually is
EBITDA stands for earnings before interest, taxes, depreciation, and amortization. Like SDE, you start with pretax net profit and add back interest, depreciation, and amortization. The key difference is what happens to owner compensation: EBITDA assumes the business pays a market-rate manager to run it, and that manager's full salary and benefits stay in as a real expense. Nothing is added back for owner pay beyond what a reasonable arm's length manager would actually cost.
This matters because EBITDA is built for a different kind of buyer, usually a private equity group, a strategic acquirer, or a larger company folding your business into an existing operation with its own management layer. They are not stepping in to run the day-to-day themselves, so they need to know what the business earns after someone else is paid to do that job.
EBITDA can be adjusted further for one-time or unusual items, which brings you to adjusted EBITDA, a version that strips out things like a lawsuit settlement, a one-time equipment loss, or a temporary spike in a single cost. Adjusted EBITDA is the number that shows up in most letters of intent for larger deals, and it is where the real negotiation over add-backs tends to happen.
The bridge between SDE and EBITDA
The difference between SDE and EBITDA, for the exact same business in the exact same year, is one thing: a market-rate manager's salary. Take SDE and subtract what it would actually cost to hire someone to replace the owner's labor, including salary, payroll taxes, and benefits, and you land on EBITDA. Add that manager's cost back into EBITDA and you land on SDE.
This is not a rough estimate you can eyeball. A market-rate manager salary depends on the industry, the hours the role demands, and the region you operate in. A general manager for a busy restaurant commands a very different salary than a general manager for a specialty trucking operation with real operational complexity. Whatever the number, it is the single figure that reconciles the two ways of describing the same profit.
Once you understand the bridge, a lot of confusing conversations with buyers start to make sense. Two people can look at the same set of financials, one call it SDE and the other call it EBITDA, and both be right, as long as they are consistent about whether owner pay is counted as profit or as an expense.
Which one applies to you
As a rough guide, owner-operated businesses under roughly $5 million in annual revenue are priced on SDE. That covers most single-location retail shops, home service companies, restaurants, salons, and small professional practices, where the owner is still the one running things or working substantial hours in the business.
Above that revenue range, especially once a business has a general manager or leadership team in place and the owner has stepped back from daily operations, buyers typically shift to EBITDA. That crossover is not a hard line drawn at a specific dollar figure. It is really about whether a buyer would need to replace the owner's labor with a hire, or whether that replacement is already built into the org chart.
If you are not sure which side of that line you fall on, ask yourself what would happen if you took a two-month vacation with no contact. If the business would struggle without you making decisions and doing hands-on work, you are almost certainly an SDE business. If it would run fine because someone else already handles that, you are closer to an EBITDA business, even if your revenue is still relatively modest.
Legitimate add-backs buyers will accept
Add-backs exist to correct for the fact that small business tax returns are often built to minimize taxable income, not to show true profitability. Legitimate add-backs include the owner's salary and payroll taxes, personal vehicle expenses run through the business, one-time legal or professional fees tied to a specific event, a one-time repair or casualty loss, and non-cash items like depreciation and amortization.
Other common ones include above-market rent paid to a related party, life insurance premiums on the owner that a new buyer would drop, and travel or meals that are clearly personal rather than business development. The test a buyer applies to every single one is whether the expense would disappear or change under new ownership, not whether it is technically deductible on a tax return.
Good documentation makes these add-backs far more credible. Bank statements, receipts, and a written explanation for each line item turn an add-back from something a buyer has to take on faith into something they can verify. Buyers who cannot verify an add-back will often just refuse to count it.
Add-backs buyers reject
Buyers push back hard on add-backs that look like an attempt to inflate the number rather than correct for owner-specific quirks. A common rejected add-back is a second employee's salary when that person is doing real, necessary work, even if they happen to be a family member. Buyers will also reject add-backs for expenses they believe they would still have to pay, such as a bookkeeper, basic marketing, or software subscriptions the business genuinely needs to operate.
Vague add-backs without documentation, like a lump-sum figure for miscellaneous personal expenses with no receipts behind it, are almost always cut or heavily discounted. The same goes for one-time add-backs that keep recurring year after year; if a repair or legal cost shows up in three consecutive years, it is not really one-time, and a buyer will treat it as a normal cost of doing business.
The general rule is that every dollar you add back has to survive the question a buyer's advisor will ask, which is: if I bought this business tomorrow, would I still be paying this? If the honest answer is yes, it does not belong in your add-back list, no matter how you have historically treated it on your tax return.
Why using the wrong basis is the costliest mistake you can make
Here is where owners lose real money. Say a business generates $600,000 in SDE. Most small businesses trade between 2 and 4 times SDE, so a fair price range would be roughly $1.2 million to $2.4 million. Now suppose that same owner hears that businesses in their sector trade at 4 to 5 times EBITDA and applies 5 times to their $600,000 SDE figure. That suggests $3 million, which is not realistic, because EBITDA multiples are meant to apply to EBITDA, a smaller number that already has a market-rate manager salary subtracted out.
If that same business had $500,000 of EBITDA after subtracting a $100,000 manager salary from its $600,000 SDE, then 5 times EBITDA gives you $2.5 million, which is a very different, and far more defensible, number. The multiple and the profit base always have to match.
This mistake cuts both ways. An owner who applies an SDE-style multiple of 3 times to an EBITDA figure will undervalue their own business and may accept an offer well below what a buyer would actually have paid. Getting the basis wrong, in either direction, is the single most expensive misunderstanding an owner can walk into a negotiation with, because it either scares off legitimate buyers with an unsupportable asking price or leaves real money on the table.
How to present your number to a buyer credibly
Start by stating clearly which figure you are using, SDE or EBITDA, and show your math from the top line of your tax return or P&L down to that figure, with every add-back listed separately and labeled. A one-page bridge that a buyer's accountant can follow in five minutes builds far more trust than a single number handed over without support.
Back up every add-back with a source, whether that is a bank statement, an invoice, a payroll record, or a letter from your tax preparer confirming a one-time event. Buyers and their lenders will ask for this documentation anyway during due diligence, so having it ready upfront speeds up the process and signals that you are not hiding anything.
Present three years of financials, not just the most recent year, and show the trend. A buyer wants to see that your SDE or EBITDA is stable or growing, not the product of one unusually good year. If your multiple range comes from a sector benchmark, treat it as a typical range rather than a promise, since actual deal terms always depend on the specific business, its growth, its customer concentration, and current market conditions.
When to get a quality of earnings review
A quality of earnings review, often called a QoE, is an independent examination of your financials performed by an accounting firm, separate from a standard audit or tax filing. It verifies that your revenue and profit are real, recurring, and properly recorded, and it tests every add-back you have proposed against bank records and source documents.
For smaller SDE-based deals, a full QoE is often not worth the cost. But once a business is large enough to be priced on EBITDA, especially in deals above a few million dollars in enterprise value, buyers, particularly private equity groups and lenders financing the deal, will frequently require one before closing.
Getting your own QoE done before you go to market, sometimes called a sell-side QoE, can be worth the cost even on the smaller end of the EBITDA range. It lets you find and fix any weak add-backs or accounting issues before a buyer's team finds them, and it gives you a credible, third-party-tested number to negotiate from rather than a spreadsheet you built yourself.
A hypothetical HVAC company: same business, two labels
Picture a hypothetical HVAC company generating $700,000 of pretax profit before add-backs. The owner works full time managing crews and takes a $120,000 salary that is added back, along with $30,000 of personal vehicle and travel costs and $50,000 of interest and depreciation, bringing SDE to $900,000. At a typical range of 2 to 4 times SDE, this business might be valued between $1.8 million and $3.6 million. Now suppose a buyer wants to see EBITDA instead. They subtract a market-rate general manager salary of $110,000, landing on EBITDA of $790,000. HVAC businesses typically trade at 3.5 to 7 times EBITDA, and a company this size usually sits nearer the bottom of that band, so at 3.5 to 4.5 times, EBITDA-based value comes out to roughly $2.8 million to $3.6 million. The two labels, correctly matched to their own multiples, describe the same business and land in a compatible range. It is only when the multiples get crossed with the wrong profit figure that the numbers stop making sense.

Common questions
Can a business have both an SDE and an EBITDA figure at the same time?
Yes. Every business has both numbers; they are just two different ways of measuring profit depending on whether owner labor is counted as profit or as a cost. Which one a buyer actually uses to make an offer depends mostly on the size of the business and whether it already has management in place.
Is EBITDA always a bigger number than SDE?
No, SDE is virtually always larger than EBITDA for the same business, because SDE adds back the owner's full compensation while EBITDA leaves a market-rate manager salary in as an expense. The gap between the two is exactly that manager salary.
What if my accountant has never calculated SDE or EBITDA for me?
That is common, since these are deal-specific figures rather than standard accounting line items. You or a business broker can build the calculation directly from your tax returns and P&L, starting with pretax profit and working through add-backs one at a time.
Do buyers ever negotiate the add-backs after an offer is made?
Frequently. Add-backs are often revisited during due diligence once a buyer's accountant reviews your bank statements and receipts, and unsupported add-backs can be reduced or removed at that stage, which can lower the final price even after a letter of intent is signed.
Should I calculate SDE myself before talking to a buyer?
Yes, having your own SDE or EBITDA calculation ready, with documentation for each add-back, puts you in a much stronger negotiating position than waiting for a buyer to calculate it for you and present their own, likely lower, version.
Why do multiples vary so much between industries?
Multiples reflect how buyers view risk, growth, and how replaceable the owner is. A trucking company at 3 to 4.5 times EBITDA typically carries more competitive and cyclical risk than a medical practice at 4 to 6 times adjusted profit, which often has more stable, recurring demand.
What happens if I mix SDE add-backs into an EBITDA calculation?
You end up with a number that is neither accurate SDE nor accurate EBITDA, and a buyer's advisor will catch it quickly during review. Mixing the two erodes your credibility and can slow down or derail a deal even if the underlying business is strong.
At what exact revenue does a business switch from SDE to EBITDA pricing?
There is no fixed dollar line; roughly $5 million in revenue is a common reference point, but the real driver is whether the business still depends on the owner's daily labor or already runs through a management team, since that is what determines which figure a buyer needs.
