💰 What is EBITDA?

EBITDA (Earnings Before Interest, Tax, Depreciation and Amortization) is a measure of a company's cash-generating ability from operations. It shows operating profitability before accounting for financing decisions, tax obligations, and non-cash accounting expenses.

Key Point: EBITDA is often considered a proxy for operating cash flow. By excluding non-cash expenses (depreciation and amortization), it shows how much cash a business generates from its core operations. This makes it especially useful for comparing companies with different asset bases or capital structures.

The EBITDA Formula

EBITDA = Revenue - COGS - Operating Expenses (excluding D&A)
Or starting from net income:
EBITDA = Net Income + Interest + Taxes + Depreciation + Amortization

Simple Example

Revenue: $1,000,000
Cost of Goods Sold: $400,000
Gross Profit: $600,000
Operating Expenses (cash):
Rent: $60,000
Salaries: $280,000
Utilities: $20,000
Other: $40,000
Cash Operating Expenses: $400,000
Non-Cash Expenses (added back for EBITDA):
Depreciation: $35,000
Amortization: $15,000
EBITDA = $600,000 - $400,000
EBITDA = $200,000

Interpretation: This business generates $200,000 in operating cash before paying interest, taxes, or accounting for asset depreciation.

Why EBITDA Matters

  • Cash focus: Approximates cash generated from operations
  • Capital structure neutral: Ignores how company is financed
  • Asset neutral: Doesn't penalize capital-intensive businesses
  • Comparability: Compare companies regardless of depreciation methods
  • Valuation metric: Used in M&A and business valuations
  • Debt coverage: Shows ability to service debt obligations

What Gets Added Back for EBITDA?

Depreciation:

The allocation of the cost of physical assets (equipment, buildings, vehicles) over their useful life. It's an accounting expense but doesn't involve actual cash leaving the business.

Amortization:

Similar to depreciation but for intangible assets like patents, trademarks, goodwill, or software. Also a non-cash accounting expense.

💡 Why Add Back Non-Cash Expenses?

If you bought a $100,000 machine that lasts 10 years, accounting rules make you expense $10,000/year as depreciation. But you only paid cash once (year 1). EBITDA adds back that $10,000 because it's not actual cash leaving the business each year. This gives a clearer picture of operating cash generation.

EBITDA vs EBIT vs EBT

Metric What's Excluded Best For
EBITDA Interest, Tax, Depreciation, Amortization Comparing capital-intensive companies, cash generation
EBIT Interest, Tax Operating profitability, less capital-intensive firms
EBT Tax only Seeing impact of financing on pre-tax earnings
Net Income Nothing Final profitability, shareholder returns

When to Use EBITDA

Ideal for:

  • Capital-intensive industries (manufacturing, telecom, utilities)
  • Comparing companies with different asset ages
  • Merger & acquisition valuations
  • Assessing debt servicing capacity
  • Startups or growth companies with high D&A
  • Comparing across different tax jurisdictions

Less useful for:

  • Companies with minimal capital expenditure needs
  • Understanding true economic profit
  • Companies that need significant ongoing capex
  • Assessing shareholder value (use net income)
⚠️ EBITDA Limitations

EBITDA can be misleading because it ignores capital expenditures. A company might show strong EBITDA but require massive ongoing investment to maintain assets. Always look at EBITDA alongside actual cash flow and capex requirements. Some say "EBITDA" really stands for "Earnings Before I Tricked the Dumb Auditor" when misused!

EBITDA in Business Valuation

EBITDA is commonly used in business valuation through EBITDA multiples:

Enterprise Value = EBITDA × Industry Multiple

Typical EBITDA Multiples by Industry:

Industry Typical Multiple
Software/SaaS 10-20x
Healthcare services 8-12x
Manufacturing 6-10x
Retail 4-8x
Restaurants 3-5x

Example: A software company with $2M EBITDA might be valued at $20-40M (10-20x multiple).

🔢 Calculating EBITDA Step-by-Step

Method 1: Top-Down from Revenue

Example: ManufactureCo

Step 1: Calculate Gross Profit

Revenue: $5,000,000
Cost of Goods Sold: $2,000,000
Gross Profit: $3,000,000

Step 2: Identify Cash Operating Expenses

Expense Type Amount Cash or Non-Cash?
Salaries & wages $1,200,000 Cash
Rent & facilities $300,000 Cash
Utilities $80,000 Cash
Marketing $200,000 Cash
Insurance $60,000 Cash
Other operating $160,000 Cash
Depreciation $250,000 Non-Cash (exclude)
Amortization $50,000 Non-Cash (exclude)
Total Cash Expenses $2,000,000

Step 3: Calculate EBITDA

EBITDA = Gross Profit - Cash Operating Expenses
EBITDA = $3,000,000 - $2,000,000
EBITDA = $1,000,000

Method 2: Bottom-Up from Net Income

Using the same ManufactureCo example:

Net Income: $450,000
Add back: Income Tax ($150,000)
Add back: Interest Expense ($100,000)
Add back: Depreciation ($250,000)
Add back: Amortization ($50,000)
EBITDA = $450,000 + $150,000 + $100,000 + $250,000 + $50,000
EBITDA = $1,000,000

Both methods arrive at the same $1,000,000 EBITDA!

EBITDA Margin

EBITDA Margin = (EBITDA / Revenue) × 100
For ManufactureCo:
EBITDA Margin = ($1,000,000 / $5,000,000) × 100
= 20%

A 20% EBITDA margin means the company generates $0.20 in EBITDA for every $1 of revenue.

Industry EBITDA Margin Benchmarks

Industry Typical EBITDA Margin Notes
Software/SaaS 25-40% High margins, low physical assets
Telecom 30-45% High margins but capital intensive
Healthcare 15-25% Varies by service type
Manufacturing 12-20% ManufactureCo at 20% is strong
Retail 8-15% Competitive, lower margins
Restaurants 10-18% Better than net margins due to D&A
Airlines 15-25% High depreciation on aircraft

Comparing EBITDA, EBIT, and Net Income

Let's see how the same company looks under different metrics:

Metric Amount Margin
Revenue $5,000,000 100%
EBITDA $1,000,000 20.0%
Less: Depreciation & Amortization ($300,000)
EBIT $700,000 14.0%
Less: Interest ($100,000)
EBT $600,000 12.0%
Less: Taxes ($150,000)
Net Income $450,000 9.0%
Key Insight: EBITDA of $1M looks much stronger than net income of $450k. The $550k difference comes from depreciation ($300k), interest ($100k), and taxes ($150k). For a capital-intensive business, EBITDA gives a better sense of cash-generating power.

Adjusted EBITDA

Companies often calculate "Adjusted EBITDA" by also excluding one-time or unusual items:

EBITDA: $1,000,000
Add back: Restructuring costs ($80,000 one-time)
Add back: Legal settlement ($50,000 unusual)
Add back: Loss on asset sale ($20,000)
Adjusted EBITDA: $1,150,000

Adjusted EBITDA shows "normalized" operating performance excluding unusual events.

⚠️ Watch for Aggressive Adjustments

Some companies abuse "Adjusted EBITDA" by excluding too many items or recurring costs to inflate results. Always scrutinize what's being adjusted and whether those items are truly one-time. If adjustments are large or frequent, be skeptical.

🌍 Real-World EBITDA Applications

1
Telecom Company Valuation

Scenario: TelecomNZ is being valued for potential acquisition.

Financial Overview:

Revenue: $800,000,000
COGS: $320,000,000
Operating Expenses (cash): $240,000,000
Depreciation: $120,000,000 (huge network infrastructure)
Amortization: $20,000,000 (spectrum licenses)
Interest: $30,000,000
Taxes: $21,000,000

Calculating Key Metrics:

Metric Calculation Amount
EBITDA $800M - $320M - $240M $240,000,000
EBIT $240M - $120M - $20M $100,000,000
Net Income $100M - $30M - $21M $49,000,000

Enterprise Value Using EBITDA:

Industry EBITDA multiple for telecom: 8x
Enterprise Value = $240M × 8
= $1,920,000,000 (≈$1.92 billion)
Why EBITDA Works Here: Telecom has massive depreciation ($120M) from network infrastructure. EBITDA of $240M shows true cash-generating ability better than $49M net income. The $1.92B valuation reflects the business's operating strength, not just accounting profit.
2
Restaurant Chain Analysis

Scenario: DinerChain owns 15 restaurants and wants to open 10 more.

Current Performance:

Revenue: $12,000,000
Food costs (COGS): $3,600,000 (30%)
Labour: $4,200,000
Rent: $1,800,000
Other operating: $900,000
Depreciation: $360,000 (equipment, furniture)
Interest: $180,000
EBITDA = $12M - $3.6M - $4.2M - $1.8M - $0.9M
EBITDA = $1,500,000

EBITDA Margin:

EBITDA Margin = ($1,500,000 / $12,000,000) × 100
= 12.5%

Debt Coverage Ratio:

Annual Interest Payments: $180,000
Interest Coverage = EBITDA / Interest
= $1,500,000 / $180,000
= 8.3x coverage (very healthy)
💡 Expansion Decision

With 8.3x interest coverage and healthy 12.5% EBITDA margin, DinerChain has strong capacity to take on debt for expansion. Lenders typically want minimum 2-3x coverage, so 8.3x provides comfortable cushion. The EBITDA metric shows they generate sufficient operating cash to service expansion debt.

Software vs Manufacturing Comparison

Scenario: Comparing two $10M revenue companies in different industries.

SoftwareCo (SaaS Business):

Line Item Amount % of Revenue
Revenue $10,000,000 100%
COGS (hosting) $1,000,000 10%
Operating Expenses $6,000,000 60%
Depreciation $200,000 2%
EBITDA $3,000,000 30%
EBIT $2,800,000 28%

ManufactureCo (Heavy Equipment):

Line Item Amount % of Revenue
Revenue $10,000,000 100%
COGS $5,000,000 50%
Operating Expenses $3,000,000 30%
Depreciation $800,000 8%
EBITDA $2,000,000 20%
EBIT $1,200,000 12%

Comparison:

SoftwareCo Advantages:
  • Higher EBITDA margin (30% vs 20%)
  • Minimal depreciation impact (EBITDA ≈ EBIT)
  • More scalable, asset-light model
ManufactureCo Reality:
  • Lower EBITDA but still solid 20%
  • Large depreciation ($800k) impacts EBIT significantly
  • EBITDA better represents cash generation than EBIT
  • Needs ongoing capital investment
4
Private Equity Acquisition

Scenario: PE firm is acquiring SmallBiz for 6x EBITDA.

SmallBiz Financials:

EBITDA: $4,000,000
Purchase Price: 6x EBITDA = $24,000,000
Down Payment (equity): $6,000,000
Debt Financing: $18,000,000
Interest Rate: 6% = $1,080,000/year

Post-Acquisition Debt Service:

EBITDA: $4,000,000
Interest Coverage = $4,000,000 / $1,080,000
= 3.7x (healthy coverage)

PE Firm's Expected Returns:

Improve EBITDA to $6M over 5 years (50% growth)
Exit at 6x EBITDA = $36M
Repay debt: -$12M (paid down $6M over 5 years)
Net proceeds: $24M
Initial equity: $6M
Return: 4x equity in 5 years (≈32% IRR)
💡 Why EBITDA Drives PE Deals

Private equity focuses on EBITDA because: (1) it's a good proxy for debt servicing capacity, (2) multiples are standard for valuation, (3) improvements in EBITDA directly increase exit value, and (4) it's comparable across different capital structures (important when using leverage).
