If you've started looking into selling your business, you've probably seen two acronyms popping up again and again: SDE and EBITDA. So what's the difference between SDE and EBITDA? Both measure what your business earns, but in different ways. In business, SDE (seller's discretionary earnings) counts your salary as profit. EBITDA replaces it with what a hired manager would cost. Mixing the two up can throw off your valuation by hundreds of thousands of dollars.
This SDE vs. EBITDA guide explains both in plain English, with a sample business you can follow using your own numbers. You'll learn which measure buyers will likely use for your business, how each turns into an estimated sale price, and which add-backs hold up in due diligence. For the full selling process, see our guide on how to value and sell your business.
Key Takeaways
- SDE is what the business earns for one full-time owner-operator.
- Adjusted EBITDA is roughly SDE minus the cost of replacing the owner.
- Smaller, owner-run businesses bought by individuals are usually priced on SDE; businesses bought by professional buyers are priced on EBITDA.
- SDE multiples are lower than EBITDA multiples, so never compare them directly.
- Document every add-back, because buyers will test them.
What does SDE stand for in business?
The SDE meaning in business is seller's discretionary earnings: the total financial benefit a business provides to one full-time owner-operator in a year. That includes pre-tax profit, plus the owner's salary and benefits, plus certain expenses that won’t continue predictably under a new owner.
To see how it works, let's follow a sample business through this guide: an HVAC service company with about $3 million in annual revenue. (For what drives value in this industry specifically, see how to value and sell an HVAC business.) On paper, it shows $300,000 in pre-tax profit. But that number leaves out a lot of what the business actually provides to its owner.
Your tax return is built to keep taxable income low, so it rarely shows the full picture. SDE starts with profit and adds back items a buyer wouldn't carry forward. For our sample HVAC company:
Sample figures for illustration only.
Each of these lines is called an “add-back” and each one has a good reason for being included. The owner's pay goes back in because SDE measures what the business earns for its operator. Interest reflects how the business was financed, not how it runs. Depreciation and amortization are accounting expenses, not cash leaving the business that year. Personal and one-time costs simply won't continue under a new owner.
One rule to know: SDE only adds back one owner's pay. If two partners both work in the business, the second salary usually stays in as a real cost, because a buyer would still need to pay someone to do that job.
That's a big reason why SDE is used as the standard number for smaller, owner-run businesses. The typical buyer plans to step in and run the company themselves, so they want to know what it would pay them for doing the job you do today.
What is EBITDA?
EBITDA stands for earnings before interest, taxes, depreciation, and amortization. It measures what a business earns from its core operations, before financing decisions, taxes, and non-cash accounting expenses. Unlike SDE, however, EBITDA assumes the business pays someone a normal salary to run it.
When you're selling a business, EBITDA almost always means adjusted EBITDA. It starts the same way as SDE, adding back interest, depreciation, personal expenses, and one-time costs. The difference is the owner's pay. That one line is the real difference in seller's discretionary earnings vs. EBITDA. Instead of adding your full salary back as profit, adjusted EBITDA replaces it with what the business would pay a qualified manager.
Back to our HVAC company example. The owner earns $200,000, but hiring a new general manager or CEO to run the business would cost about $150,000, including salary, benefits, and payroll taxes. Adjusted EBITDA keeps that $150,000 as an expense.
Sample figures for illustration only.
At SIG Partners, we look at EBITDA because we place an experienced CEO in every business we acquire, so we need to know what the business earns after paying for that leadership.
SDE vs. EBITDA: what's the difference?
SDE shows what a business earns for an owner who runs it, while adjusted EBITDA shows what it earns after paying someone else to run it. Everything else in the EBITDA vs. SDE comparison follows from that one difference.
Which one will buyers use for my business?
It mostly depends on your size and on who's likely to buy.
SDE is the usual measure for smaller, owner-run businesses, often with yearly earnings under $1 million. The typical buyer is an individual who plans to run the business day to day, so they want to know what it will pay them. At SIG Partners, we target businesses with revenues over $4 million, so SDE is not a metric that we use during closing.
Adjusted EBITDA is the measure professional buyers like private equity firms and holding companies, including SIG Partners, use to value a business, because they’re planning for the day you leave. SDE adds your salary back into earnings, which makes the number look bigger on paper. But once you step away, someone still has to run the company, and that person gets paid. A buyer will put a market-rate CEO salary right back on the books, which is why EBITDA is the number that shows what your business actually earns without you. That’s true even if you’re still running things day to day. Most owners we talk to are.
Many businesses in the lower middle market can fall somewhere in between. When you're selling a business in that range, it's worth asking every buyer directly which measure their offer is based on. Two offers can look far apart on paper and turn out to be close once you know what each one is multiplying.
How SDE and EBITDA become a sale price
Most small and mid-sized businesses are priced the same basic way:
Earnings × multiple = estimated value
The multiple reflects how much risk a buyer sees and how much growth they expect. We cover how buyers think about multiples in what stable businesses are worth to buyers today. SDE multiples are lower than EBITDA multiples, because a buyer paying on SDE is also buying themselves a job. A buyer paying on EBITDA is buying earnings after the cost of that job is already covered.
Here's how that could play out for our sample HVAC company:
Sample figures and multiples for illustration only. Actual multiples vary by industry, size, and market conditions.
Used correctly, the two methods land in roughly the same place. The problems start when they get mixed up. Apply the 4.0× EBITDA multiple to SDE, and you'd expect $2.54 million, about $600,000 more than any buyer is likely to pay.
Multiples also move with the market. By one estimate, small business EBITDA multiples fell from roughly 6.7× at a 2017 peak to around 4.3× in 2025. Buyers have also become less willing to pay for one unusually strong year. That's why steady results over three years usually matter more than your best twelve months.
Why not just price a business on revenue? Revenue is simple to find, but it ignores profitability: two companies with the same sales can earn very different amounts. EBITDA and SDE take more work to calculate and depend on which add-backs a buyer accepts. That's why they're the numbers buyers actually use, and revenue multiples mostly show up as rough rules of thumb.
SDE vs. cash flow vs. free cash flow
If you've browsed businesses for sale online, you've probably seen "cash flow" listed as the key number. In most small business listings, that's SDE, sometimes called seller's discretionary cash flow. So in that context, the cash flow SDE meaning is the same thing: earnings available to one owner-operator.
Free cash flow is different, and buyers look at it too. It starts with EBITDA and subtracts the cash the business needs to keep running: equipment and vehicle purchases, the money tied up in inventory and receivables, and taxes. For an equipment-heavy business, the gap between EBITDA and free cash flow can be large.
Take our HVAC company. If it spends $60,000 a year replacing trucks and equipment, a buyer will factor that in, even though it never shows up in SDE or EBITDA. When comparing cash flow vs. SDE on a listing, or free cash flow versus EBITDA in an offer, make sure you know which one is being used.
Add-backs buyers accept, and ones they question
Add-backs are where SDE and EBITDA can rise or fall the most, so expect buyers to test every one.
Usually accepted, with documentation:
- Your salary, benefits, and payroll taxes
- Truly one-time costs, like a lawsuit settlement or storm damage repair
- Personal expenses run through the business, backed by receipts
Often questioned:
- "One-time" costs that show up every year in a different form
- Rent paid to yourself when you own the building. Buyers will adjust it to market rate, up or down.
- Family members on payroll who don't work full time, or who are paid above or below market
- Expenses you cut recently to make profit look higher
The rule of thumb: if you can't prove it with a receipt, invoice, or clear explanation, don't count on it. Many buyers will test add-backs through a quality of earnings report during due diligence. Aggressive add-backs that don't hold up can cost you more than the add-back itself, because they make buyers question the rest of your numbers.
Common mistakes sellers make with SDE and EBITDA
- Comparing an SDE multiple to an EBITDA multiple. Hearing that businesses in your industry sell for 5× and applying it to SDE can set expectations hundreds of thousands of dollars too high. Always check which earnings number a multiple refers to.
- Counting add-backs you can't document. Gather receipts and records for every add-back before you go to market.
- Leaning on one strong year. Buyers look at trends. Show at least three years of results, and be ready to explain any spikes or dips. It's one of the mistakes business owners make when selling.
- Forgetting the owner's replacement cost. If a buyer will need to hire for your role, your EBITDA has to account for it, whether you calculate it or they do.
- Ignoring equipment and working capital needs. A business that needs heavy reinvestment is worth less than its SDE or EBITDA alone suggests.
Frequently asked questions
What does SDE stand for in business?
SDE stands for seller's discretionary earnings. It's the total financial benefit a business provides to one full-time owner-operator in a year: pre-tax profit, plus the owner's salary and benefits, plus personal and one-time expenses that won't continue under a new owner. It's the standard earnings measure for smaller, owner-run businesses.
Is SDE the same as cash flow?
Often, yes. Most small business listings label SDE as "cash flow" or "seller's discretionary cash flow." It isn't the same as free cash flow, which subtracts the money a business needs to keep running, like equipment purchases and inventory. Buyers look at both, especially for businesses with trucks or heavy equipment.
Is SDE always higher than EBITDA?
SDE is almost always higher. Adjusted EBITDA equals SDE minus the cost of replacing what the owner does in the business. If a manager already runs day-to-day operations and the owner is largely hands-off, that cost can be close to zero, and the two numbers end up nearly the same.
Does SDE include the owner's salary?
Yes, for one owner. SDE adds back the owner's full salary, benefits, and payroll taxes, because it measures what the business earns for the person running it. If two partners both work in the business, the second salary usually stays in as a real cost.
What if my business already has a general manager?
Then their salary is already a business expense and stays in both SDE and adjusted EBITDA. The adjustment only covers what you, the owner, still do. If you're largely hands-off, the two numbers end up about the same. If you still handle a key role like sales, buyers subtract what it would cost to hire for it.
What is a good SDE multiple?
It depends on size, industry, growth, and risk. Many small, owner-run businesses sell for roughly 2–3× SDE, according to a recent Insight Report from BizBuySell.
Businesses with recurring revenue, steady growth, and a team that runs without the owner tend to earn higher multiples.
Know which number you're being paid on
SDE and EBITDA measure the same business in two ways. SDE shows what it earns for an owner who runs it. Adjusted EBITDA shows what it earns after paying someone else to. Neither is better. What matters is using the right one for your business, and knowing which one a buyer is using when they make an offer.
Before you go to market, calculate both, document every add-back, and look at three years of results rather than one. For the full process, see our guide on how to value and sell your business.
