Quick answer
EBITDA = Net Income + Interest + Tax + D&A. Example: Net Income $5M + Tax $1.5M + Interest $500K + D&A $800K = EBITDA $7.8M. EBITDA Margin = EBITDA / Revenue × 100.
How to use this EBITDA calculator
Choose your method with the toggle at the top of the calculator:
- From Net Income (bottom-up): enter Net Income, Tax Expense, Interest Expense, and D&A. The calculator shows EBT and EBIT as intermediate steps, then EBITDA. Enter Revenue optionally to get EBITDA Margin.
- From Revenue (top-down): enter Revenue, COGS, and Operating Expenses excluding D&A. Because D&A is excluded from OpEx, the result is already EBITDA - not EBIT. EBITDA Margin is shown automatically since Revenue is already entered.
Enter all figures in the same currency unit (e.g., all in thousands, or all in millions). The result cards abbreviate large numbers for display.
What is EBITDA?
EBITDA stands for Earnings Before Interest, Taxes, Depreciation, and Amortization. It measures how much profit a business generates from its core operations, before the effects of how it is financed (interest), where it is taxed (taxes), and how it accounts for capital investment (D&A).
Because it strips out these financing and accounting variables, EBITDA allows you to compare the operational performance of two companies regardless of their capital structure or tax jurisdiction - a key requirement in M&A (Mergers and Acquisitions) analysis, private equity valuation, and bank lending.
EBITDA is not a GAAP metric. It does not appear on a standard income statement. You calculate it by starting from Net Income and adding back the four removed items.
EBITDA explained to a beginner
Imagine you own a bakery. This year you earned $200,000 in sales and spent $120,000 on ingredients and staff, leaving $80,000 operating profit. But you also paid $10,000 in interest on your oven loan, $15,000 in taxes, and your accountant wrote off $5,000 in equipment wear (depreciation). Your net income is $50,000.
EBITDA simply adds all four items back: $50,000 + $15,000 tax + $10,000 interest + $5,000 D&A = $80,000. That $80,000 is what the bakery earned from baking - before the bank, the taxman, and the accountant's write-offs got involved.
It lets you compare two bakeries on equal footing even if they borrowed different amounts or operate in different tax regions.
EBITDA formulas
There are two equivalent methods:
Bottom-up (most common)
This is the most frequently used formula for calculating EBITDA. It starts from Net Income on the income statement:
$$\text{EBT} = \text{Net Income} + \text{Tax Expense}$$
$$\text{EBIT} = \text{EBT} + \text{Interest Expense}$$
$$\text{EBITDA} = \text{EBIT} + \text{Depreciation} + \text{Amortization}$$
Or in one line:
$$\text{EBITDA} = \text{Net Income} + \text{Interest} + \text{Tax} + \text{D\&A}$$
Top-down
This formula starts from Revenue and works down to operating profit before D&A:
$$\text{EBITDA} = \text{Revenue} - \text{COGS} - \text{Operating Expenses (excl. D\&A)}$$
Both methods yield the same EBITDA. The bottom-up method is preferred in practice because all inputs are clearly labelled line items on the income statement. The top-down method is useful when you want to verify operating cost structure.
EBITDA Margin converts EBITDA into a comparable percentage:
$$\text{EBITDA Margin} = \frac{\text{EBITDA}}{\text{Revenue}} \times 100$$
Worked examples for EBITDA
| Company | Net Income | Tax | Interest | D&A | EBITDA |
|---|---|---|---|---|---|
| SaaS startup | $2,000,000 | $600,000 | $200,000 | $300,000 | $3,100,000 |
| Manufacturing co | $50,000,000 | $20,000,000 | $10,000,000 | $25,000,000 | $105,000,000 |
| Retail chain | $30,000,000 | $10,000,000 | $5,000,000 | $8,000,000 | $53,000,000 |
| Loss-making startup | -$3,000,000 | $0 | $500,000 | $1,200,000 | -$1,300,000 |
| Telecom provider | $80,000,000 | $35,000,000 | $20,000,000 | $65,000,000 | $200,000,000 |
The telecom row in the table above illustrates why context matters when reading EBITDA. D&A of $65M adds back more than the net income itself, lifting EBITDA to $200M from an $80M net income base.
That 2.5x difference is not hidden profit - it reflects the physical infrastructure (towers, cables, switches) that telcos depreciate over decades. Reading the EBITDA figure without understanding the CapEx required to maintain those assets gives a misleading picture of the cash economics.
For capital-intensive businesses, I always pair EBITDA with a CapEx intensity check before drawing any conclusions.
EBITDA in valuation
EBITDA is the denominator in the most widely used valuation multiple in private markets: EV/EBITDA (Enterprise Value divided by EBITDA). It measures how many years of EBITDA it would take to pay back the full enterprise value of the business.
| Industry | Typical EV/EBITDA multiple | Typical EBITDA Margin |
|---|---|---|
| SaaS / Software | 15x – 30x | 15% – 30% |
| Telecom | 6x – 10x | 30% – 40% |
| Healthcare | 10x – 16x | 15% – 25% |
| Manufacturing | 6x – 10x | 10% – 20% |
| Retail | 5x – 8x | 5% – 10% |
| Oil & Gas | 4x – 8x | 20% – 35% |
Lenders also use EBITDA in leverage covenants. A typical leveraged buyout covenant might require Net Debt / EBITDA ≤ 4.0x. If EBITDA falls, the company may breach the covenant and trigger a renegotiation or accelerated repayment.
Adjusted EBITDA adds back non-recurring items (restructuring charges, one-time legal settlements, stock-based compensation) to produce a "normalised" figure. In M&A, sellers typically present Adjusted EBITDA; buyers scrutinise each add-back carefully.
When I review a seller's Adjusted EBITDA in a deal, the first thing I do is rebuild it from reported EBITDA line by line. If the same restructuring charge appears in two or three consecutive years of the reconciliation, it is not non-recurring - and accepting it as an add-back overstates the normalised earnings of the business.
Limitations of EBITDA
EBITDA has well-known critics. Charlie Munger called it "bullshit earnings" because it excludes depreciation - a real economic cost that reflects capital consumption. Warren Buffett noted that EBITDA ignores the CapEx required to maintain and grow a business.
Key limitations to understand:
- Ignores CapEx: A business with heavy capital expenditure requirements (e.g., airlines, railways) looks healthier on EBITDA than it truly is. Free Cash Flow (Operating Cash Flow minus CapEx) is a more conservative measure.
- Not GAAP: Companies can define and present EBITDA differently. Always check the footnotes when reading reported EBITDA figures.
- Can be gamed: Aggressive add-backs inflate Adjusted EBITDA. Common questionable add-backs include "growth investments," recurring restructuring charges, and stock-based compensation.
- Not cash flow: EBITDA ignores changes in working capital. A company with growing EBITDA but deteriorating receivables can still run out of cash.
The CapEx blind spot is the one that bites acquirers most often. I've reviewed deals where a 10x EBITDA multiple looked reasonable on paper, until the maintenance CapEx requirements were pulled out - a business generating $20M EBITDA but spending $15M annually on capital to maintain operations is producing $5M of real cash, not $20M.
Frequently asked questions about EBITDA
What is EBITDA?
Earnings Before Interest, Taxes, Depreciation, and Amortization. It measures operating profitability by adding back four non-operating or non-cash items to Net Income, enabling comparisons across companies with different capital structures and tax situations.
What is the EBITDA formula?
EBITDA = Net Income + Interest Expense + Tax Expense + Depreciation + Amortization. Equivalently: Revenue minus COGS minus operating expenses (excluding D&A).
What is a good EBITDA margin?
It depends heavily on the industry. SaaS typically targets 20–30%, telecom 30–40%, manufacturing 10–20%, retail 5–10%. Compare against sector peers, not an absolute threshold.
What is the difference between EBITDA and EBIT?
EBIT stops at operating income - it includes D&A as expenses. EBITDA adds D&A back, making it higher and closer to operating cash flow. The difference matters most in capital-intensive industries with large D&A charges.
What is Adjusted EBITDA?
Adjusted EBITDA further adds back non-recurring items: restructuring costs, M&A expenses, one-time charges, or stock-based compensation. It aims to show "normal" operating profitability. Always scrutinise add-backs - some are genuinely one-time, others recur every year.
Can EBITDA be negative?
Yes. A company running operating losses will have negative EBITDA. This is common in early-stage startups and distressed businesses. Negative EBITDA means the core business is not yet profitable even before non-cash charges.
