SDE vs EBITDA — Which Valuation Method Applies to Your Business?

If you've spent any time researching what your business is worth, you've run into two acronyms that show up constantly: SDE and EBITDA. Both are used to value businesses. Both involve adding things back to your profit. They look similar on the surface but produce very different numbers and using the wrong one will either give you false expectations or leave you underselling yourself in negotiations.

If you haven't yet worked out a baseline number for your business, start with our guide on how much your business is worth first.

Here's the plain-English version of what each one actually means, when each one applies to your business, and why the distinction matters more than most owners realize.

The core difference in one sentence

SDE asks: what does this business put in the owner's pocket? EBITDA asks: what does this business produce as a standalone operation, independent of who runs it?

That single distinction determines everything about when each method gets used and why.

What SDE is and how it's calculated

SDE stands for Seller's Discretionary Earnings. It's the valuation method used for small, owner-operated businesses, typically those generating under $1M–$2M in annual earnings.

The idea behind SDE is straightforward: when an individual buyer acquires a small business, they're planning to step into the owner's role themselves. They want to know the total economic benefit the business produces for whoever runs it full time, not just the profit on paper, but everything the business puts in the owner's hands including salary, perks, and personal expenses that flow through the company.

To calculate SDE, you start with your net profit and add back:

Your full owner's salary and benefits because a new owner working full time would pay themselves from the business, and this figure belongs in the earnings calculation. Interest expense because this reflects how the current owner chose to finance the business, not what the business itself earns. Taxes because tax obligations change with ownership structure. Depreciation and amortization, non-cash accounting charges that don't reflect actual cash flow. Personal expenses run through the business like a car, a phone, travel, meals, a family member's salary if they're not performing a market rate role. One time or non-recurring costs, a legal dispute that's resolved, a major one-off equipment repair, moving costs.

What you're left with is the true cash the business generates for whoever owns and operates it. That number gets multiplied by a market rate, typically 2x–4x for small businesses to arrive at a valuation.

A simple example: A business owner pays themselves $200,000 a year, runs $30,000 in personal expenses through the business, and shows $120,000 in net profit on their tax return. Their SDE is roughly $350,000. At a 3x multiple, the business is worth approximately $1.05M.

What EBITDA is and how it's calculated

EBITDA stands for Earnings Before Interest, Taxes, Depreciation, and Amortization. It measures what the business produces as an operating entity, independent of its ownership structure, financing decisions, and tax situation.

The key difference from SDE is how it handles owner compensation. EBITDA does not add back the owner's full salary. Instead, it normalizes owner compensation to what a professional manager would cost to replace them. If the current owner pays themselves $300,000 but a hired CEO would cost $120,000, only the $180,000 excess gets added back. The $120,000 market rate replacement cost stays as an expense, because a buyer who doesn't plan to run the business themselves would need to spend that money on management.

This makes EBITDA the right metric for businesses acquired by companies, private equity firms, or investors who aren't stepping into the operator role. They need to know what the business earns as a standalone operation with proper management in place, not what it produces for a hands on owner.

EBITDA multiples are higher than SDE multiples, typically 4x–12x or more depending on the sector, but they're applied to a lower earnings number. Done correctly, both methods should produce a similar final valuation for the same business. The multiple changes because the earnings base changes.

Which one applies to your business

The answer comes down to three things: the size of your earnings, your ownership structure, and who your likely buyer is.

Use SDE if:

Your annual earnings (owner benefit) are under $1M–$2M. You are actively involved in running the business day to day. Your likely buyer is an individual, someone using SBA financing, personal capital, or a search fund to buy themselves a job and a business simultaneously. You are a solo owner or partnership where both partners are operationally active.

In this scenario, SDE is what buyers in your market will use. It's also what business brokers use when representing businesses in this size range, because it reflects what an owner operator actually takes home. Using EBITDA here would systematically undervalue your business by ignoring the full benefit of owner compensation.

If you're a startup founder raising capital rather than selling an established business, the valuation framework is completely different. Here's what investors actually look for when valuing a startup.

Use EBITDA if:

Your annual earnings are above $1M–$2M. Your business has professional management in place and doesn't depend on you specifically to operate. Your likely buyers are private equity firms, strategic acquirers, or other companies, not individual owner-operators. You have multiple locations, departments, or business units that make an owner-operator model impractical.

In this scenario, institutional buyers will apply an EBITDA framework. They're not planning to run the business themselves, so the owner's total compensation is irrelevant to them, what matters is the standalone profitability they're acquiring.

The grey zone — $1M to $2M in earnings:

If your business sits between $1M and $2M in annual earnings, you may be in range for both methods and both buyer types. This is actually a favorable position, it means you can potentially attract both individual buyers (who think in SDE) and smaller PE or strategic buyers (who think in EBITDA), which creates competition and tends to push your price higher. An M&A advisor in this zone will often present financials both ways to maximize buyer interest.

Why this matters for your negotiations

Here's where most business owners get confused and where confusion costs money.

If you're a small business owner who's heard that businesses sell for "5x or 6x earnings," that figure almost certainly refers to EBITDA not SDE. The same business valued at 3x SDE and 6x EBITDA can produce nearly identical final valuations, because SDE is a larger number (it includes your full salary) and EBITDA is a smaller number (it nets out a market-rate replacement salary). The multiple looks higher on EBITDA precisely because the earnings base is lower.

This creates a trap: a small business owner hears "5x multiples" and assumes their business should be worth 5x their SDE. It shouldn't, 5x SDE would be an extremely unusual outcome for a small owner-operated business. The realistic range is 2x–4x SDE, which for a business with $400k in SDE puts the value at $800k–$1.6M. That's a real, good outcome for a well-run small business, but it's a different number than 5x SDE would suggest.

Understanding which earnings base your business should be valued on, and what realistic multiples look like in your specific sector, is the starting point for any meaningful conversation about what you're actually worth.

Once you know which method applies, the next question is what you can do to move your number higher, here's exactly how to increase your business valuation before you sell.

One more thing: adjusted EBITDA

You'll also hear the term "adjusted EBITDA" frequently, which adds another layer of normalization on top of standard EBITDA. Adjusted EBITDA removes one-time revenues and expenses, a legal settlement in one year, an unusually large contract that won't repeat, costs from a business line you've since closed, to show what the business produces in a normalized, ongoing state.

When sophisticated buyers talk about EBITDA, they almost always mean adjusted EBITDA. And when they're doing due diligence, they'll be making their own adjustments regardless of how you've presented the number, which is why having a clear understanding of your own add-backs, and being able to defend each one with documentation, matters enormously in negotiations.

Knowing your number

The practical takeaway from all of this: before you enter any conversation about selling or raising capital, you need to know which earnings metric applies to your business, what your earnings look like under that metric, and what realistic multiples in your sector look like against that base.

That combination, the right earnings metric applied to sector specific and company specifc transaction data, is what MergeX is built to provide. Not a generic calculator that applies the same formula to every business, but a real benchmark against actual deals in your vertical.
