SDE works well for small, owner-operated businesses. As a company grows and a management team runs it, buyers — especially private equity, strategic acquirers and larger lenders — switch to EBITDA.
What EBITDA measures
Earnings Before Interest, Taxes, Depreciation and Amortization. It strips out:
- Interest — because the buyer will finance the business differently.
- Taxes — because they depend on the owner’s structure and situation.
- Depreciation and amortization — non-cash accounting charges.
What’s left approximates the operating earnings the business generates, comparable across companies regardless of how they’re financed.
Adjusted EBITDA
Raw EBITDA usually needs normalizing:
- Owner compensation adjusted to market. If the owner pays themselves far more or less than a manager doing that job would earn, the difference is adjusted.
- One-time expenses added back — a lawsuit, a relocation, a one-time consulting project.
- Non-operating items removed — gains on selling equipment, personal expenses.
- Run-rate adjustments — sometimes, for documented changes like a new contract or a cost removed. Buyers scrutinize these heavily.
SDE vs EBITDA
| SDE | Adjusted EBITDA | |
|---|---|---|
| Owner pay | Adds back one owner’s full compensation | Keeps a market salary for the owner’s role |
| Typical business | Smaller, owner-operated | Larger, with management in place |
| Typical buyer | Individuals, owner-operators | Private equity, strategics, larger buyers |
| Question answered | What does this produce for one owner? | What does this earn as a company? |
The same business can be described both ways. The numbers will differ because of how owner pay is treated — so always ask which one is being quoted. See seller’s discretionary earnings.
Why EBITDA multiples vary
A multiple is just a shorthand for risk and growth. Buyers pay higher multiples for:
- Size — larger businesses are usually seen as less risky.
- Recurring revenue and long customer relationships.
- Diversified customers and suppliers.
- Strong management that will stay.
- Growth with a believable path to continue.
- Industries in favor with buyers and lenders.
And lower multiples for owner dependence, concentration, volatile earnings, heavy capital needs or a shrinking market. I don’t publish multiples here because they move with markets and vary enormously by deal; an advisor with current data for your industry can give you a realistic range.
How buyers test adjusted EBITDA
- Reconcile to tax returns and financial statements.
- Challenge every adjustment for documentation and logic.
- Look at monthly trends, not just annual totals.
- Analyze customer and product profitability.
- Commission a quality-of-earnings review on meaningful deals. See financial due diligence.
When a business crosses from SDE to EBITDA
Usually when the owner is no longer the main operator — there’s a general manager or leadership team, and the owner could step away without the business changing much. That’s also when the business tends to become more valuable, because it’s less dependent on one person. If you want to make that shift before selling, build the leadership team and operating rhythm first. See how to build a leadership team and what increases business value.
A note for owners
If a buyer quotes you a value based on EBITDA and you’ve been thinking in SDE, the numbers can look shockingly different. Neither is wrong. Make sure you’re comparing the same measure, and understand what salary the buyer is assuming for the role you play today.
Questions to ask when someone quotes EBITDA
- Is this raw or adjusted EBITDA?
- What adjustments were made, and is each documented?
- What salary was assumed for the owner’s role?
- Are there run-rate adjustments, and how confident should a buyer be in them?
- What capital spending does the business need each year to keep running?
- How has the figure moved month to month, not just year to year?
Getting clear answers keeps everyone honest and prevents surprises late in diligence, when re-trading a price damages trust on both sides.
How I look at it as an operator
When I evaluate a business, I care less about the label and more about two things: how much cash a well-run version of this business reliably produces, and what it would take to get there. If the EBITDA depends on the owner working nights, it isn’t the number I’d pay for. If it’s produced by a team and a system, it is.

Common EBITDA mistakes sellers make
- Quoting EBITDA when the business really depends on the owner. If you’d need to hire someone expensive to replace you, the adjusted figure has to reflect that.
- Stacking optimistic run-rate adjustments. Buyers will remove most of them.
- Ignoring seasonality. A strong quarter annualized isn’t a year.
Questions people ask
What does EBITDA stand for?
Earnings before interest, taxes, depreciation and amortization — a measure of operating earnings that removes financing choices, taxes and non-cash charges so businesses can be compared more easily.
What is adjusted EBITDA?
EBITDA after normalizing adjustments — adding back true one-time or non-operating expenses and adjusting owner compensation to a market salary for the role the owner performs.
What is an EBITDA multiple?
A factor buyers apply to adjusted EBITDA to estimate value. Multiples vary by industry, size, growth, risk, customer concentration and market conditions, which is why there is no single ‘right’ multiple.
