What Is EBITDA and Why Is It Important​

The founder tells the investor, “We made a profit this year.” “What was your EBITDA?” says the investor. And then the conversation shifts. If you’ve ever nodded along, trying to work out what that word means in your head, this guide is for you.
Why does EBITDA matter? Lenders, buyers, and investors use it to compare businesses on an equal footing. It also has some real blind spots. Let’s break it down so you can use the number well and question it when you need to.

Quick Answer: What Is EBITDA?

EBITDA means earnings before interest, tax, depreciation, and amortisation. It shows how much a company earns from its main business before taking into account financing choices, tax bills and accounting write-offs. Take it as a rough index of operating strength.
The U.S. Securities and Exchange Commission takes notice of the same four items. SEC correspondence defines EBITDA as earnings before interest, taxes, depreciation, and amortisation, and says a measure calculated in another way should carry another title, such as “adjusted EBITDA.”

What Each Letter Means

• E (Earnings): The earnings figure you begin with is usually net income.
• I (Interest): The price of borrowing. Not on how well it runs, but on how you funded the business.
• T (Taxes): Income tax. Location- and structure-specific rates and rules.
• D (Depreciation): The systematic reduction in the value of tangible assets like laptops, machines, or vehicles.
• A (Amortisation): The systematic expensing of intangible assets like software or acquired licenses.

“Take those four out, and you see earnings from day-to-day operations.”

How to Calculate EBITDA

There are two ways you can get to the same number. Choose what you want based on the data you have.

• EBITDA = net income + interest + taxes + depreciation + amortisation.
• EBITDA = operating income (EBIT) + depreciation + amortisation.

Next, let’s run the numbers on a hypothetical company. Say a small startup in India reports these numbers:

• Turnover: ₹2.00 crore
• Operating cost ex depreciation & amortisation: ₹1.50 crore
• Depreciation & Amortisation: ₹10 lakh
• Interest: ₹8 lakh
• Tax: ₹8 lakh

Write-offs reduce operating costs by ₹50 lakh. That’s the EBITDA. Thus, depreciation and amortisation of ₹10 lakh is deducted to arrive at an operating income of ₹40 lakh. After taxes and interest, net income is ₹24 lakh. Put the pieces back together (₹24 + ₹8 + ₹8 + ₹10 lakh), and you’re back to 50 lakh rupees.
It is very easy to find out the EBITDA margin. 50 lakh / 2.00 crore = 25%. Margins allow you to compare companies of different sizes.

EBITDA vs. EBIT vs. Net Income

Each step up the table takes more cost off. That makes the number look better and also makes it less complete.

Why Is EBITDA Important?

These are the main reasons why professionals request it.

It Compares Companies More Fairly
Two companies can have different net income and perform equally well. One borrowed a lot. One bought equipment last year. EBITDA does not consider those differences. Coursera’s explainer notes that it normalises certain financial metrics so that comparisons between companies are easier.

It Shows Operating Strength
EBITDA answers one simple question: does the core business of this business make money before you get to financing and accounting choices? If you see EBITDA going up for a few quarters in a row, that means the operation itself is improving.

It Anchors Valuation Talks
Buyers and investors often value a company as a multiple of EBITDA. It is also a figure used by business owners to show prospective buyers the financial health of their company. It’s on The Startup Gig’s homepage, next to due diligence, modelling and data room support, which gives you an idea of how closely these topics connect in a real transaction.

It Helps Lenders Judge Debt Capacity
Banks look at a business’ earnings before interest and tax in relation to its debt. Ratios based on EBITDA, such as debt to EBITDA, provide lenders a quick read on the strength of repayment. A higher EBITDA gives a company more borrowing power.

It Guides Internal Decisions
Founders can track EBITDA monthly, by product line or branch. That tells you which parts of the business are paying their way and which are bleeding.

The Limits of EBITDA

EBITDA is a useful measure, but it’s not the whole story. That’s where it falls flat.

It Ignores Capital Spending
Depreciation is a non-cash expense, but the assets that are being depreciated do wear out and eventually need to be replaced. Warren Buffett noted this gap in his 2000 shareholder letter and asked if management believes that someone else is paying for capital expenditures. A company that continues to purchase machines can have a healthy EBITDA and still find itself lacking cash.

It Is Not Cash Flow
EBITDA also ignores changes in working capital, like unpaid invoices to customers or inventory you had to buy. Earnings might look good, but those items are cash eaters. Always read EBITDA along with the cash flow statement.

Companies Calculate It Differently
Definitions drift because EBITDA is not an official accounting measure. Coursera notes that inconsistent formula use is a drawback, since companies may calculate the components differently. That is what “Adjusted EBITDA” is for. It strips out one-off item management calls. So read each adjustment before you trust the total.

Regulators Watch How It Is Presented
In the US, there are rules for companies that report it publicly. According to SEC guidance, if a company uses EBITDA as a performance measure, it must reconcile EBITDA to net income, not to operating income. The rule exists because the figure is misleading if shown by itself.

It May Matter Less for Early-Stage Startups
Many young companies have negative EBITDA as they build. For them, burn rate, runway, and unit economics often give a better picture. EBITDA is more meaningful as the business matures to stable earnings.

How to Read EBITDA Like an Investor: Next Steps

This checklist should be used any time someone gives you an EBITDA number.

• Look up the definition: Ask if it’s just plain EBITDA or adjusted EBITDA.
• Compare it with the net profit: A big gap means big interest, tax, or write-off costs.
• Look at capital expenditure: If the business has to keep reinvesting, forget about that.
• Review cash flow: Ensure that earnings are converted into cash.
• Margin and trend analysis: A good quarter is not proof. ‘More’ means several in a row.
• Comparison with peers: Compare with companies in the same industry, because asset needs are very different.

Founders in need of help building the numbers behind these checks can look at what advisory firms offer. The Startup Gig’s Virtual CFO and Tax vertical provides services like financial modelling, financial projections, MIS, budgeting, and valuation reports. Having clean month numbers will speed up any discussion on EBITDA.

Wrapping Up

EBITDA offers you a quick, comparable view of operating earnings. It helps with valuation, lending and day-to-day decisions. It also hides capital requirements, cash timing, and creative adjustments. You will put it to good use. How was it built? Combine it with net income and cash flow.
