SDE and EBITDA both measure business earnings, but using the wrong one — or misunderstanding which applies to your business — can lead to a valuation conversation that’s off by a meaningful amount before it even really starts.
What SDE Actually Measures
Seller’s Discretionary Earnings adds back the owner’s own compensation, along with one-time or personal expenses, to show the total financial benefit available to a single owner-operator. It answers the question: if I bought this business and ran it myself, what would it actually generate for me before I pay myself anything? This is the standard metric for small, owner-operated pet care businesses where the owner is actively working in the business day to day.
What EBITDA Actually Measures
Earnings before interest, taxes, depreciation, and amortization strips out financing and accounting decisions to show core operating profitability, but unlike SDE, it does not add back owner compensation — it assumes a paid manager is already running the business. This makes EBITDA the more appropriate metric for larger, more established businesses with real management structure beyond the owner.
Why the Distinction Matters for Small Pet Care Businesses
Most pet sitting and dog walking businesses are small enough that the owner’s personal involvement is central to daily operations, which makes SDE the more accurate and more commonly used metric in this space. Using EBITDA on a business that’s still fundamentally an owner-operator role would understate true earnings, since it wouldn’t add back the value of the owner’s labor the way SDE does.
Where the Crossover Point Typically Falls
There’s no exact revenue threshold, but many advisors start shifting the conversation toward EBITDA once a business has an SDE in the range of $500,000 to $1,000,000 and a genuine management layer capable of running operations without the owner’s daily involvement. Below that range, SDE remains the more relevant and more commonly requested metric by buyers, brokers, and lenders alike.
Why Multiples Differ Between the Two
Because EBITDA already assumes a paid manager, EBITDA multiples for larger businesses tend to look higher on paper than SDE multiples for smaller ones, even though the underlying economics can be comparable once you account for what each metric does and doesn’t include. Comparing an SDE multiple directly to an EBITDA multiple without adjusting for this difference is a common and costly mistake for owners doing informal research.
A Side-by-Side Numeric Example
Take a pet sitting business generating $200,000 in net profit before the owner’s salary, with the owner also drawing an $80,000 salary from the business. Under SDE, the calculation adds that salary back, along with any personal expenses run through the business, to arrive at a discretionary earnings figure that might land around $290,000 once smaller add-backs like a personal phone plan or a one-time legal fee are included. Under EBITDA, that same business — assuming it already had a paid manager instead of an owner-operator — would show a much lower figure, since a market-rate manager salary would need to be deducted rather than added back. Applying the wrong metric to the wrong situation can make the same business look dramatically more or less valuable than it actually is.
Common Mistakes Owners Make With These Terms
The most frequent mistake is an owner hearing an EBITDA multiple mentioned in a general business article or podcast and assuming it applies directly to their own small, owner-operated business, then feeling shortchanged when a broker explains why SDE is the relevant metric instead. The reverse mistake also happens — a growing business with real management depth continuing to think in SDE terms, which can actually undersell the business to a buyer who would value it more highly under a proper EBITDA framework that reflects its more mature operational structure.
How Lenders and Buyers Treat Each Metric
SBA lenders financing small business acquisitions are very familiar with SDE and use it as a standard input in their own underwriting calculations, since most SBA-financed deals involve owner-operator businesses in exactly this size range. Larger, more sophisticated buyers — private equity groups, strategic acquirers already running similar operations — think natively in EBITDA terms, since it’s the standard metric across corporate finance generally, and applying to them with an SDE-based pitch alone can make a business appear smaller or less institutionally credible than it actually is.
Which Metric Should You Track Even Before Selling
Owners planning a future sale benefit from calculating their SDE annually, even years before listing, since tracking it over time shows whether the business is actually building sellable value or simply generating income the owner has to keep showing up for. If the business eventually grows enough to justify an EBITDA-based conversation instead, that transition will be obvious from the numbers themselves — a real management team, reduced owner involvement, and earnings that no longer depend on adding back a single person’s salary.

Add-backs that get challenged during due diligence
Not every add-back an owner proposes survives a buyer’s scrutiny. Legitimate add-backs typically include owner salary, personal vehicle expenses run through the business, one-time legal or consulting fees, and discretionary perks like a company credit card used for non-business travel. What tends to get challenged or rejected outright: a family member’s salary for work they don’t actually perform, “one-time” expenses that recur every year, and personal expenses so intertwined with business operations that separating them cleanly isn’t credible. A buyer’s accountant will typically want documentation for every add-back over a modest threshold, so owners who wait until the sale process to start organizing this paperwork often lose weeks of momentum reconstructing three years of receipts.
How this plays out in an actual pet care acquisition
A dog walking and pet sitting company with $650,000 in revenue and a single owner handling scheduling, some walks, and all client relationships will almost always be valued on SDE, and buyers will expect that SDE figure to roughly represent what they’d earn stepping into the owner’s shoes full time. If that same company has grown to $2.5 million in revenue with a general manager, a scheduling coordinator, and a team of 15 W-2 or 1099 sitters who don’t need the founder’s daily involvement, a sophisticated buyer is far more likely to ask for EBITDA, because the business has crossed into something closer to a standalone operating company rather than a job the owner happens to also own.
What this means for how you build the business now
If your long-term plan is to sell, the choice between SDE and EBITDA isn’t just an accounting detail — it’s a signal of what kind of buyer you’re building toward. Staying in SDE territory means you’re likely selling to another owner-operator, often financed through an SBA loan, who wants to step into a role similar to the one you’re leaving. Building toward EBITDA means investing in management infrastructure, documented systems, and a team that can run operations without you, which broadens your buyer pool to include private equity roll-ups and strategic acquirers who pay more but expect more structural maturity in return. Neither path is inherently better, but conflating the two, or drifting between them without a clear target, tends to produce a business that doesn’t fit cleanly into either buyer category when it’s finally time to sell.
Getting a credible number before you talk to anyone
Before entering any conversation with a broker, lender, or prospective buyer, it’s worth calculating your own SDE (or EBITDA, if your management structure justifies it) using the last three years of financials, documenting every add-back with a receipt or explanation, and having a bookkeeper or accountant sanity-check the result. A number you can defend line by line carries far more weight in a negotiation than a round figure pulled from a rule of thumb, and it puts you in a position to correct a buyer’s assumptions rather than simply reacting to whatever figure they propose first.
Frequently asked questions
Can a business be valued on both metrics at once? Sometimes a broker will present both figures during a transition period, especially if the business is straddling the SDE/EBITDA crossover point, but the final agreed-upon valuation almost always settles on one primary metric that both sides accept as the basis for the multiple applied.
Does industry matter, or is this crossover point universal? The general principle holds across small service businesses, but the specific revenue range where the shift happens varies by industry margin structure — a lower-margin business needs more revenue to reach the same SDE or EBITDA dollar figure than a higher-margin one.
Should I hire a professional to calculate this instead of doing it myself? A DIY calculation is a reasonable starting point for your own planning, but once you’re within a year or two of an actual sale, a business broker or M&A advisor familiar with pet care transactions will catch add-backs and adjustments an owner typically misses or overstates.
