Adjusted EBITDA: The Number That Actually Determines What Your Shop Is Worth

If you watched Tuesday's video on EBITDA, you know the basics. Your shop earns revenue, pays its expenses, and what's left over before interest, taxes, depreciation, and amortization is your EBITDA. That number is the starting point for any valuation conversation.

But here's where things get interesting. And where most shop owners either gain or lose six figures in a sale.

The number buyers actually use is not your raw EBITDA. It's your Adjusted EBITDA. And understanding the difference might be the most important financial concept you learn this year if you have any plans to eventually sell.

What "Normalizing" Actually Means

When a buyer looks at your financials, they're trying to answer one question: what does this business actually earn if I own it instead of you?

That's a different question than what it earns right now.

Your shop might be running expenses through the P&L that a professional owner wouldn't have. Not because you're doing anything wrong. That's just how privately held businesses work. Owners run their lives through the company. It's legal, it's common, and it affects how a buyer reads your books.

So buyers go through a process called normalizing. They add back the expenses that were real to you but won't exist under new ownership. The result is Adjusted EBITDA.

What Gets Added Back

Here are the most common add-backs in a collision repair shop:

Owner compensation above market. If you're paying yourself $300,000 a year and a competent general manager would cost $120,000, a buyer adds back $180,000. That's not a judgment on what you deserve. It's a reflection of what it actually costs to run the business without you.

Personal vehicle expenses. The truck or SUV the business pays for that you use personally. The insurance on it. Fuel. Maintenance. These are real expenses on the books but they go away under new ownership.

Personal benefits run through the business. Cell phones for family members. Health insurance for relatives who don't work there. Country club memberships. These are legitimate perks of business ownership. But a buyer won't carry them.

One-time expenses. A roof replacement. A lawsuit settlement. A piece of equipment that blew up and had to be replaced. These events won't repeat, so they shouldn't be used to calculate ongoing earnings.

The Example That Makes It Click

Say your EBITDA is $400,000. That's what the raw number shows.

But when you walk through the add-backs with your advisor, you find your salary is $80,000 above what a GM would cost, your personal vehicle runs $15,000 through the books, and you had a one-time legal settlement last year for $25,000.

Add those back, and your Adjusted EBITDA is $520,000.

At a 4x multiple, that's the difference between a $1.6 million valuation and a $2.08 million valuation. That's $480,000 on the same business.

Where Owners Get Into Trouble

Here's the part that doesn't get talked about enough. Add-backs only work if they're defensible.

I've seen owners come into a conversation having added back nearly everything. Every personal expense, every piece of equipment, every salary line. The adjusted number looks great on paper. And then the buyer starts asking questions.

If you can't explain each add-back clearly, if you can't show documentation, if the adjustment doesn't hold up to scrutiny, the buyer discounts it. Or they walk.

The credibility of your Adjusted EBITDA matters as much as the number itself. Buyers have seen every version of this. They know what's legitimate and what's creative accounting.

A good rule to live by: if you'd be uncomfortable explaining it out loud to a skeptical audience, don't add it back.

Why This Matters Even If You're Not Selling

You don't have to be in active sale conversations for this to be relevant.

Knowing your Adjusted EBITDA gives you a clearer picture of what your business is actually worth. It helps you make better decisions about what to run through the company. It helps you prepare for a conversation that might be two years away, or ten years away.

And it helps you catch problems early. If your Adjusted EBITDA is lower than you expected, that's information. It tells you where to focus.

The shops that get the best outcomes in a sale are the ones that understood these numbers before anyone ever made an offer.
