SDE vs. EBITDA: How Small Business Sale Prices Are Actually Calculated

You've spent years building your business. Now you're starting to think about what it's worth. You Google around, see some references to "multiples," and immediately hit a wall: SDE vs. EBITDA — how small business sale prices are actually calculated depends on which metric a buyer uses, and most owners have no idea which one applies to them. Getting this wrong doesn't just create confusion. It can cost you six figures at the closing table.

Let's break this down the way a buyer actually thinks about it.

SDE vs. EBITDA: What They Actually Mean

SDE (Seller's Discretionary Earnings) is the total financial benefit a single owner-operator takes from the business. It starts with net income, then adds back the owner's salary, personal benefits, one-time expenses, non-cash charges like depreciation, and interest. The idea is simple: if a buyer steps into your shoes, this is the cash they can expect to control.

EBITDA (Earnings Before Interest, Taxes, Depreciation, and Amortization) strips out financing and accounting decisions but does not add back a market-rate salary for management. It assumes the business has — or will need — a paid management layer that the owner doesn't personally fill.

Here's the core distinction:

• SDE is used when the owner is the business — they're running day-to-day operations and their compensation is baked into the earnings.
• EBITDA is used when the business runs with professional management, or could reasonably do so after the sale.

For most businesses in the $750K to $3M range — the kind we work with across Newton, Wellesley, Cambridge, and the Route 128 corridor — SDE is the standard. Once you cross roughly $3M to $5M in revenue with a real management team, buyers start shifting to EBITDA.

How the Multiple Gets Applied (and Why It Matters So Much)

The sale price of a small business is almost always expressed as a multiple of SDE or EBITDA. But here's what trips owners up: the multiples are different ranges for each metric, and mixing them up creates wildly inaccurate expectations.

Typical ranges for Main Street and lower middle-market deals:

• SDE multiples: 2.0x – 4.0x (most small businesses)
• EBITDA multiples: 3.5x – 6.0x+ (larger, management-run companies)

EBITDA multiples look higher, but remember — EBITDA already subtracts a management salary. So a business with $600K in SDE might show only $400K in EBITDA after accounting for a $200K GM salary. Watch what happens:

• At 3.0x SDE: sale price = $1.8M
• At 4.0x EBITDA: sale price = $1.6M

Same business. Different metric. $200K gap. This is why understanding which framework applies to your company isn't academic — it's the single most consequential financial question of your exit.

A Real-World Scenario: Two Businesses on Route 128

Consider two commercial services companies, both doing about $2.5M in revenue, both based along the Route 128 corridor west of Boston.

Company A: The owner runs operations, manages the sales pipeline, and handles key accounts personally. She pays herself $280K in total compensation. After recasting, SDE is $520K. A qualified buyer applies a 2.8x multiple. Implied value: $1.46M.

Company B: The owner stepped back two years ago. An operations director and a sales manager run the day-to-day. EBITDA — after paying both managers — is $410K. A strategic buyer sees the management infrastructure and applies a 4.5x multiple. Implied value: $1.85M.

Company B commands a higher price despite having lower owner earnings. Why? Because the buyer isn't purchasing a job — they're purchasing a system. The management layer de-risks the transition and makes the business attractive to a wider pool of acquirers, including private equity groups and search funds active in the Greater Boston market.

This is why we tell owners who are 1-3 years out from a sale: the most valuable thing you can do right now might not be growing revenue. It might be removing yourself from operations.

Forensic Recasting: Where the Real Money Hides

Whether your business is valued on SDE or EBITDA, the accuracy of that number depends entirely on how thoroughly your financials are recast. Most owners undercount their add-backs. They forget the personal vehicle running through the books, the one-time legal bill from a lease renegotiation, the family member on payroll who won't be part of the deal.

At Nova Exit Partners, we call this forensic financial recasting. Erik Kretschmar — who has sold four of his own businesses — personally leads this process because he's been on both sides of the table. He knows what buyers scrutinize, what add-backs they'll accept, and what they'll challenge.

We routinely find $50K to $150K in legitimate add-backs that owners missed. At a 3x multiple, that's $150K to $450K in additional sale price. For a business owner in Needham or Waltham preparing to fund their next chapter, that's not a rounding error — that's life-changing money.

What This Means for Your Exit Timeline

If you're a business owner in Greater Boston thinking about selling in the next one to three years, here's what to do with this information:

• Know which metric applies to you. If you're the primary operator, expect SDE-based valuation. If you have management in place, you may qualify for EBITDA-based pricing — and a higher multiple.
• Get a professional recasting done now. Not next year. The earlier you identify your real earnings, the more time you have to improve them before going to market.
• Think about de-risking. Every function you remove from your personal plate potentially shifts your valuation from SDE territory to EBITDA territory. That shift alone can add 20-40% to your sale price.

Understanding how small business sale prices are calculated isn't just financial literacy — it's exit strategy. The owners who get the best outcomes are the ones who learn this early and build toward it deliberately.

If you'd like to know exactly where your business stands — which metric applies, what your recast earnings look like, and what a realistic sale price range might be — we'll walk through it with you. No pitch, no pressure. Just clarity.
