EBITDA

What Is EBITDA?

EBITDA is earnings before interest, taxes, depreciation, and amortization: a measure of operating profitability that strips out financing decisions, tax jurisdiction, and non-cash charges. It approximates what a company's core operations earn, which makes it the standard basis for valuation multiples, lender covenants, and comparisons between businesses with different capital structures.

How EBITDA Works

Two companies can run identical operations and report very different net income. One is loaded with debt and pays interest. One sits in a high tax jurisdiction. One bought its equipment outright and depreciates it, while the other leases. EBITDA removes those four differences so the operating businesses can be compared directly.

That is also the source of every criticism aimed at it. Interest is a real payment. Taxes are a real payment. Depreciation and amortization are non-cash today, but they represent assets that eventually have to be replaced. EBITDA is a comparison tool, not a measure of what a company can spend.

Buyers and lenders lean on it anyway because it is the cleanest available proxy. Enterprise value to EBITDA is the workhorse valuation multiple in private markets, and most credit agreements express leverage as a maximum debt to EBITDA ratio.

How to Calculate EBITDA

There are two paths to the same number. Start from the bottom of the income statement and add back, or start from operating income and add back only the non-cash charges.

Formula: EBITDA = Net Income + Interest + Taxes + Depreciation + Amortization

Formula: EBITDA Margin = EBITDA / Revenue x 100

Take a company with $6,000,000 in revenue and $500,000 in net income. It paid $50,000 in interest and $80,000 in taxes, and it recorded $70,000 of depreciation and $30,000 of amortization.

EBITDA = $500,000 + $50,000 + $80,000 + $70,000 + $30,000 = $730,000.

EBITDA margin = $730,000 / $6,000,000 x 100 = 12.2 percent.

The cross check: operating income is $630,000, and adding back $70,000 of depreciation and $30,000 of amortization gives the same $730,000.

EBITDA in Plain English

EBITDA asks a narrow question: before we account for how this business is financed, where it is taxed, and how its accountants spread out the cost of past purchases, does it make money selling its product? A high EBITDA margin means the core engine works. It does not mean there is cash in the bank on the fifteenth of the month.

Adjusted EBITDA and What Gets Added Back

Most companies report adjusted EBITDA alongside the standard version. Typical add-backs include restructuring charges, litigation settlements, acquisition costs, and stock based compensation.

Some of these are defensible. A one time legal settlement genuinely does distort a single year. Others are not. Stock based compensation is a recurring cost of employing engineers and salespeople; adding it back does not make it disappear. Adjusted EBITDA is not defined under GAAP, which means the definition is whatever the company says it is.

The practical rule for reading someone else's adjusted EBITDA: find the reconciliation table, look at the size of the add-backs relative to the number itself, and ask which of them will appear again next year. If the same add-back shows up three years running, it is an operating expense wearing a costume.

Where EBITDA Misleads SaaS Operators

Software businesses have low depreciation and high stock based compensation, which is exactly backwards from the industries EBITDA was designed for. Three specific distortions matter.

Capitalized software development moves engineering salaries off the income statement and into amortization, which EBITDA then removes. Two SaaS companies with the same spend can show very different EBITDA depending on capitalization policy alone.

Deferred revenue means cash timing and profit timing diverge. A company collecting annually upfront can show weak EBITDA and a strong bank balance, or the reverse.

Sales commissions are paid immediately but amortized over the expected customer life under current revenue standards, so fast growth flatters EBITDA relative to actual cash out the door.

EBITDA, Free Cash Flow, and the Rule of 40

Free cash flow answers the question EBITDA cannot: after capital expenditures, working capital swings, interest, and taxes, how much cash is left? A company with positive EBITDA and negative free cash flow is funding growth from somewhere, and it is worth knowing where.

The Rule of 40 combines growth and profitability into one number, most often revenue growth rate plus EBITDA margin, with 40 as the passing mark. The company above growing 28 percent with a 12.2 percent EBITDA margin lands at 40.2 and clears the bar. Whether it clears the bar on cash is a separate question.

EBITDA and the Closing Motion

EBITDA is silent on timing, and timing is where most B2B software companies actually struggle. A team can close a strong quarter, book profitable contracts, report healthy EBITDA, and still be short of cash because buyers pay monthly while commissions, hosting, and payroll are paid now. That gap opens in the Collect stage of the Closing Motion. Ratio does not change EBITDA. It changes when the cash behind it arrives: with Ratio Trade the buyer pays monthly or quarterly while the seller collects the full total contract value upfront, and Ratio Boost converts existing recurring contracts into upfront capital. Same reported profitability, materially different cash position.

Common Questions About EBITDA

Is EBITDA the same as operating income?

No. Operating income, or EBIT, still includes depreciation and amortization. EBITDA adds both back, so it always sits at or above operating income and reflects less of the cost of the company's asset base.

What is a good EBITDA margin for a SaaS company?

It depends entirely on growth stage. Companies growing above 40 percent often run negative EBITDA by design, while mature software businesses commonly target 20 percent or more. Judge the margin against the growth rate, not on its own.

Why do lenders care so much about EBITDA?

Credit agreements size debt capacity and set covenants as a multiple of EBITDA, because it is a rough proxy for cash available to service interest and principal. That is also why the exact definition of adjusted EBITDA in a loan document is worth negotiating carefully.

Key Takeaways

• EBITDA measures operating profitability before interest, taxes, depreciation, and amortization.
• EBITDA margin is EBITDA divided by revenue, and it feeds the profitability half of the Rule of 40.
• Adjusted EBITDA is not standardized, so read the reconciliation and question recurring add-backs.
• In SaaS, capitalized development and deferred revenue can distort EBITDA in both directions.
• EBITDA says nothing about when cash arrives, which is why free cash flow belongs beside it.
