What Is EBITDA — and Why Every Business Owner Should Know Theirs

If you've ever looked into buying or selling a business, you've run into EBITDA within about five minutes. It gets thrown around like everyone was born knowing it.

Here's what it actually means and why it matters.

EBITDA stands for Earnings Before Interest, Taxes, Depreciation, and Amortization.

That's it. You start with your earnings, then add back four things that have nothing to do with how well the business itself performs:

• Interest — what you pay on loans. That's a function of how you financed the business, not how it operates.
• Taxes — driven by your entity structure, your state, and your personal situation.
• Depreciation — an accounting entry spreading the cost of equipment over its useful life. No cash leaves the building.
• Amortization — the same idea, applied to intangible assets like patents or goodwill.

Strip those out and you're left with a cleaner picture: how much money does this business generate from actually doing business?

The whole point is comparability.

Imagine two identical shops on the same street doing the same revenue. One owner bought the building with a big mortgage; the other leases. One is an S-corp; the other is an LLC. One just wrote off a truck; the other drives a paid-off van.

Their bottom lines will look completely different — but their operations are nearly identical. EBITDA cuts through the financing and accounting noise so you can compare the businesses themselves.

That's why buyers, lenders, and brokers reach for it. It answers the question: what does this thing actually produce, before we get into who owns it and how they paid for it?

This is where it hits your wallet.

Most businesses are priced as a multiple of EBITDA. A business generating $200,000 in EBITDA selling at a 3x multiple prices around $600,000. Change the multiple to 4x and you're at $800,000 — same business, different market.

Two things follow from that:

Every dollar of EBITDA is worth several dollars of sale price. At a 4x multiple, finding $25,000 in annual savings doesn't add $25,000 to your value — it adds roughly $100,000. That's why cleaning up your numbers before a sale pays so well.

The multiple depends on risk. Larger, more stable businesses with diversified customers and an owner who isn't essential command higher multiples. Small, owner-dependent businesses with customer concentration get lower ones. Same EBITDA, very different price.

Lenders use it too. When a bank sizes a loan, they're asking whether EBITDA comfortably covers the debt payments.

Worth knowing: for smaller owner-operated businesses, you'll often see SDE — Seller's Discretionary Earnings — instead. SDE takes EBITDA a step further and adds back the owner's salary and personal perks run through the business. The logic is that a new owner-operator would be replacing that person, so those costs are theirs to redirect. For a full breakdown of how valuation multiples work in practice, see What Is My Business Worth?

Rough rule of thumb: main-street businesses tend to be priced on SDE, larger ones on EBITDA. If someone quotes you a multiple, ask which number it's applied to. A 3x on SDE and a 3x on EBITDA are wildly different prices.

Charlie Munger famously called it "bullshit earnings," and he had a point worth respecting.

It ignores real costs. Interest is money that genuinely leaves your account. Depreciation is a placeholder for equipment that eventually has to be replaced with real cash. A business with aging machinery can post a beautiful EBITDA right up until it needs a new roof and three new trucks.

It's not cash flow. EBITDA says nothing about inventory tying up your money or customers paying 90 days late. Plenty of businesses have healthy EBITDA and no cash.

It's easy to dress up. Because "add-backs" are somewhat subjective, sellers can get creative — every questionable expense becomes a one-time event. Legitimate add-backs are documented. The rest are hopeful. If you want to know exactly where add-backs live on a tax return and how to document them properly, see How to Find Add-Backs on a Tax Return.

So use EBITDA as a starting point, not a verdict.

EBITDA is shorthand for what a business earns from operating, stripped of financing and accounting decisions. It's the language buyers, sellers, and lenders use to compare businesses and set prices.

Know yours. Know whether you should be quoting EBITDA or SDE. And understand what it leaves out — because the buyer across the table certainly will.

Not sure what your business's EBITDA is, or what multiple it would command? That conversation is worth having before you need it.
