SDE vs EBITDA vs ARR: Which Multiple Values Your SaaS

Short answer: SDE (seller discretionary earnings) values small owner-operated businesses and adds the owner's salary back into profit. EBITDA values businesses that already run without the owner and does not add the salary back. ARR multiples value SaaS on revenue instead of profit, which is why fast-growing software gets priced on ARR while a mature, profitable tool gets priced on SDE or EBITDA. Rough rule: under about $1M in earnings use SDE, above it use EBITDA, and if the business is growing above roughly 30% a year, expect an ARR multiple to win. Last updated July 2026. Educational only, not financial advice.

What is the difference between SDE and EBITDA?

The difference is one line: the owner's compensation. SDE measures what the whole business produces for a single owner-operator, so it adds the owner's salary, benefits and personal expenses back into profit. EBITDA measures what the business produces after paying someone a market wage to run it, so the owner's salary stays as an expense. Same business, two numbers, and SDE is always the larger one.

That gap exists because the two metrics answer different buyer questions. A person buying a job wants to know what they will earn running it themselves, which is SDE. A fund or strategic buyer who will install a manager wants to know what it earns after paying that manager, which is EBITDA. Quoting the wrong one to the wrong buyer makes your business look either overpriced or oddly cheap.

	SDE	EBITDA	ARR multiple
Measures	Total owner benefit	Operating profit after management	Recurring revenue, not profit
Owner salary	Added back	Kept as an expense	Not relevant
Typical deal size	Under ~$1M earnings	Above ~$1M earnings	Any size, growth-led
Typical buyer	Individual operator, small holdco	PE, strategic, search fund	Strategic, growth acquirer
Common SaaS range	3x to 5x SDE	5x to 12x EBITDA	3x to 7x ARR
Best when	Profitable, founder-run, slow growth	Profitable, has a real team	Growing fast, profit reinvested

How to calculate SDE for a SaaS business

Start with net profit from the tax return or P&L, then add back the items a new owner would not inherit. For a typical founder-run SaaS that means:

• The owner's salary, distributions and payroll taxes on them
• Interest, taxes, depreciation and amortization (the same adjustments as EBITDA)
• Owner health insurance, retirement contributions and personal phone or vehicle costs
• One-time, non-recurring costs: a rebrand, a lawsuit, a failed product line, a single large legal bill
• Discretionary spend the buyer would cut: conference travel, a course, a personal coach on the books

A worked example. A SaaS does $600,000 revenue and shows $120,000 net profit. The founder pays themselves $110,000, runs $8,000 of health insurance through the company, spent $15,000 once on a trademark dispute, and has $6,000 of depreciation. SDE is $120,000 + $110,000 + $8,000 + $15,000 + $6,000 = $259,000. EBITDA on the same business is $149,000, because the $110,000 salary stays in. At 3.5x, the SDE view prices it near $906,000 and the EBITDA view near $521,000. Nothing about the business changed. That is why the metric you present matters.

Which add-backs will a buyer actually accept?

Every seller thinks their add-backs are obvious and every buyer thinks half of them are optimistic. The test a buyer applies is simple: would this cost still exist for me next year? If yes, it is not an add-back, no matter how the seller categorizes it.

Add-back	Accepted?	Buyer's reasoning
Owner salary (in SDE)	Yes	New owner replaces it with their own
One-time legal or rebrand cost	Yes, with evidence	Genuinely non-recurring, needs an invoice
Owner health insurance, personal vehicle	Usually	Personal benefit, not business cost
A contractor doing real work	No	The work still needs doing after close
Marketing spend that drives signups	No	Cut it and revenue falls, so it is not discretionary
Inference and API costs	No	Direct cost of delivering the product
"I could run it cheaper" savings	No	Hypothetical, buyer will not pay for their own future work

Document every add-back with a source: an invoice, a bank line, a payroll record. Add-backs you can evidence get accepted quickly. Add-backs you assert in a spreadsheet get argued down one by one during diligence, and each one you lose comes off the price at full multiple. Clean expense categorization ahead of time is worth real money here, which is why sellers increasingly let software read the receipts and categorize every expense during the year rather than reconstructing twelve months of card statements the week a buyer asks.

When to use SDE vs EBITDA

Use SDE when one person runs the business and the buyer will be that person. Practically, that means earnings under about $1M, no management layer, and a founder who is still in the product daily. This covers most micro SaaS and the majority of deals under $2M in enterprise value.

Use EBITDA when the business already has a team that runs it, earnings are above roughly $1M, or the buyer is an institution. Funds model EBITDA because they will hire a general manager and they price the business net of that cost. Presenting SDE to a PE buyer just means they recalculate it themselves and quietly wonder why you did not.

The awkward middle is real. A $700,000-revenue SaaS with one part-time contractor and a founder working ten hours a week is genuinely arguable either way. In that case present both, clearly labeled, and let the buyer pick the frame that matches their plan. Sellers who present both look prepared. Sellers who present only the flattering one look like they are hiding the other.

Why SaaS often gets valued on ARR instead of either

Profit multiples assume profit is the point. In fast-growing software it usually is not, because the sensible thing to do with cash is reinvest it into growth, which suppresses profit precisely when the business is most valuable. A SaaS growing 60% a year with deliberate near-zero profit would price at almost nothing on an EBITDA multiple, which is obviously wrong, so the market prices it on revenue instead.

The practical rule: growth above roughly 30% a year, and revenue multiples usually produce the higher, more defensible number. Growth below 15% with real profit, and earnings multiples usually win. Between those, run both and lead with whichever tells the more honest story you can defend under diligence. Our breakdown of what a SaaS business actually sells for covers the current ranges in detail.

What is a good SDE multiple for a SaaS business?

Small profitable SaaS typically trades at 3x to 5x SDE, which is higher than most brick-and-mortar small businesses (often 2x to 3x) because software has better margins, no inventory and no premises. Within that band, the multiple is set by the same factors that set any SaaS price: churn, growth trend, customer concentration, and how much of the operation depends on the founder personally.

Profile	Typical SDE multiple	Why
Flat or declining, founder-dependent	2.0x to 3.0x	Buyer is acquiring a job with risk attached
Stable, low churn, documented ops	3.0x to 4.0x	Predictable, transferable, easy to run
Growing 20%+, low churn, some team	4.0x to 5.0x	Growth plus reduced key-person risk
Growing fast with expansion revenue	Price on ARR instead	Profit multiple undervalues the trajectory

Presenting your numbers so a buyer believes them

Whichever metric you lead with, the presentation rules are the same. Show trailing twelve months, not a cherry-picked quarter. Reconcile the top-line number to bank deposits and to the billing system, because that is the first thing any competent buyer does. List every add-back on its own line with an amount and a source, rather than a single "adjustments" figure. State your ARR definition explicitly, including how you treat annual prepayments and trials.

None of this is about making the number bigger. It is about making it survive scrutiny, because a defensible $250,000 SDE beats an aspirational $310,000 that gets picked apart in week four and drags the price down with the seller's credibility. The deeper walkthrough is in how to value an AI company, and SaaS churn rate benchmarks covers the retention numbers that move whichever multiple you end up using.

Next steps

Work out which frame fits your business, then put a range on it: the SaaS valuation calculator handles the ARR method and the SaaS valuation multiples page covers where each band applies. If you are getting ready to go to market, selling your SaaS business walks through preparation and venue, and SaaS M&A covers how the deal itself runs. Every listing on Buyouts shows verified MRR, ARR, growth and churn alongside a published multiple, so you can see which metric comparable businesses were actually priced on.
