SDE vs EBITDA: Which One Values Your SaaS Business?

By Phillip Mitchell, Founder & Chief Brokerage Officer, AIExchange.club

Figures are as of September 2026 and move with the market. This is general information, not financial or tax advice.

SDE vs EBITDA: the short answer

If you run your SaaS yourself and it earns under about $1 million a year, buyers will price it on SDE. Above that, or once a hired team runs it, they switch to EBITDA. Some advisors draw the line at roughly $5 million in deal value instead, which lands in the same place.

The two numbers can differ by a third or more for the same business, and each comes with its own multiple. Put an EBITDA multiple on an SDE figure and you'll misprice your company. It's one of the most common valuation mistakes in small deals.

This guide is for SaaS founders weighing a sale and for buyers sizing up a first acquisition. We'll run one example business through both numbers, then cover add-backs, which metric applies to you, and where multiples sit in 2026.

The difference between SDE and EBITDA

The whole difference comes down to how the owner's pay is treated.

What is SDE (seller's discretionary earnings)?

In business valuation, SDE (seller's discretionary earnings) is the total cash benefit one full-time owner gets from the business in a year. You start with net profit, then add back the owner's pay, any personal or one-time costs, and the items that depend on the owner's financing and tax setup.

SDE formula

SDE = net profit + one owner's total pay + personal and one-time costs + interest + taxes + depreciation and amortization

How to calculate SDE: a $600k ARR SaaS example

Take a B2B scheduling tool doing $600k ARR. The founder works on it full time, with two contractors covering support and development. Over the last 12 months it booked $600,000 in revenue and $426,000 in expenses (hosting, tools, contractors, marketing, the founder's salary and a few items below). That leaves $174,000 in net profit.

Here's how that turns into SDE:

A buyer who steps into the founder's seat can expect about $360,000 a year before paying themselves. That's the number an owner-operator cares about, and it's the one they'll put a multiple on.

What is EBITDA in business valuation?

EBITDA is earnings before interest, taxes, depreciation and amortization. In a business valuation, buyers use adjusted EBITDA: the same one-off and personal add-backs as SDE, but the owner's pay is reset to what it would cost to hire someone for the role. That salary stays in as a cost.

Adjusted EBITDA example: the same SaaS

Same scheduling tool, same year:

That's $140,000 less than SDE (39% lower), and the whole gap is the replacement salary. We assumed $140,000 with benefits for a general manager at a $600k ARR product. Advisors typically normalize owner pay to $150,000–$300,000 for lower-middle-market companies, so bigger businesses carry a bigger gap.

The salary cuts both ways. A founder who pays themselves $250,000 would see adjusted EBITDA go up when their pay is reset to market.

Recasting financial statements: add-backs buyers accept (and reject)

Recasting your financial statements means restating the P&L the way a new owner would see it. Every add-back raises your price by the amount times the multiple, so buyers check each one. A $20,000 add-back at 3.5x is $70,000 of price.

How to recast your P&L for due diligence

1. Use 12 months of accrual-based numbers (trailing twelve months), plus the two prior years if you have them.
2. List every add-back on one page with the amount, a one-line reason and the receipt or invoice behind it.
3. Keep the list short. Five solid add-backs beat fifteen soft ones, because one bad add-back makes a buyer question the rest.

When to use SDE vs EBITDA for a SaaS business

Size and who runs the business decide it. Most SaaS businesses sold on marketplaces sit in the first row.

The third row is rarer than founders hope. Marketplace deal data from 2025 shows buyers still anchor on profit unless a business is operating at real scale.

If you're in the grey zone, roughly $500k to $1.5M in earnings, calculate both. A search fund may model your business using EBITDA while an individual buyer anchors on SDE, and you'll want to recognize which number an offer is built on.

SDE vs EBITDA multiples for SaaS in 2026

Small SaaS businesses sold on SDE mostly land between 2.5x and 4x. EBITDA multiples run higher because they're applied to bigger, less owner-dependent companies.

What that means for the example business

$360,000 SDE at 2.5x–4x puts the scheduling tool at $900,000 to $1.44 million. At the 3.9x marketplace median it's about $1.4 million.

Now the classic mistake in reverse: a buyer applies that same 3.9x to adjusted EBITDA of $220,000. The offer comes in around $858,000, over $500,000 lower, for the same business. Always ask which earnings figure a multiple sits on.

Where you land inside a range depends on growth, churn, how much the business depends on you, and customer concentration. We break those down in SaaS Valuation Multiples 2026.

Common SDE and EBITDA mistakes sellers make

• Calling profit "EBITDA" when you pay yourself nothing. If you take no salary, your profit is really closer to SDE. A buyer using EBITDA will subtract a market salary, and your number drops.
• Comparing your SDE to someone else's EBITDA exit. A friend's "6x" on EBITDA and your 3.5x on SDE can be the same price for the same business.
• Adding back more than one owner. A co-founder's or spouse's pay gets reset to market, not added back in full.
• Soft add-backs with no paper trail. One add-back a buyer can't verify makes them discount the rest.
• Mixing cash and revenue. Annual plans paid upfront inflate one month's cash. Buyers spread them over the year, so do it first.
• Being the business. If every customer knows you by name and you handle all support, expect the bottom of the range. Documented processes and a contractor who can run support move you up.

SDE vs EBITDA FAQs

Is SDE always higher than EBITDA?

Almost always. The gap is roughly a market-rate salary for the owner's role, since SDE adds it back and EBITDA keeps it as a cost. The exception is a founder paying themselves well above market.

What is SDE in business valuation?

It's the total yearly cash benefit to one full-time owner: net profit plus that owner's pay, personal and one-time costs, interest, taxes, depreciation and amortization. Buyers multiply it to price owner-run businesses.

Are SDE, owner's benefit and seller's discretionary cash flow the same thing?

Yes. Brokers use the three names for the same number.

What's a good SDE multiple for a SaaS business?

SaaS under $1M ARR typically sells for 2.5x to 4x SDE. Low churn, steady growth and a business that runs without you push toward the top.

Should I pay myself a salary before selling?

It doesn't change SDE, because the owner's pay is added back either way. It does make your books cleaner and your EBITDA more honest, which matters if a larger buyer is looking.
