EV/EBITDA vs P/E Ratio: When Should an Analyst Use Each Multiple?

EV/EBITDA compares operating enterprise value with earnings before interest, tax, depreciation and amortisation. P/E compares equity price with earnings attributable to shareholders. Use the ratio that matches the claim and business economics, then examine what the denominator omits. Neither multiple measures value reliably without context about growth, risk, capital requirements and accounting quality.

Match numerator and denominator

For EV/EBITDA, the numerator includes the financing claims reflected in the defined enterprise-value bridge. EBITDA is measured before financing interest, making the pairing more consistent across different debt levels than an equity-price numerator paired with EBITDA.

P/E can be calculated as share price divided by earnings per share, or equity value divided by consistent ordinary-shareholder earnings. Net income is after interest and tax, so financing and tax differences affect the result. Define whether the earnings are trailing, forecast or normalised.

CFA Institute's comparison of market multiples identifies these claim distinctions and notes that EV/EBITDA can help comparisons across different leverage. That does not make it immune to all financing or accounting choices.

Compare two hypothetical businesses

Assume Company A has EV ₹1,000 crore, debt ₹400 crore and cash ₹100 crore, with no other bridge items. Its equity value is ₹700 crore. EBITDA is ₹100 crore, depreciation ₹20 crore, interest ₹30 crore and an illustrative tax rate 25%.

EBIT is ₹80 crore, pre-tax profit ₹50 crore and net profit ₹37.5 crore. EV/EBITDA is 10× and P/E is 700/37.5, or about 18.7×. These are synthetic values, not current company data or a recommended valuation.

Company B has the same EV and operating figures but no net debt and no interest. Equity value is ₹1,000 crore and net profit ₹60 crore under the same simplified tax assumption. EV/EBITDA remains 10×, while P/E becomes about 16.7×.

The example shows why different P/Es need not mean one operating business is cheaper. Financing changes both the equity claim and the earnings left for it. A valid comparison must consider the whole bridge and the risk borne by shareholders.

Understand what EBITDA leaves out

EBITDA does not deduct the capital expenditure needed to maintain or expand operations. Two businesses with identical EBITDA may produce very different free cash flow if one requires heavy equipment replacement. Depreciation is imperfect, but ignoring it entirely does not make assets maintenance-free.

EBITDA also omits working-capital investment and taxes. A company selling heavily on credit can report rising EBITDA while cash is tied up in receivables. Examine cash conversion, capital expenditure and operating working capital alongside the multiple.

Lease accounting can alter EBITDA and debt-like obligations. Compare companies using a consistent treatment, particularly in sectors with substantial leased assets. Acquisitions, share-based compensation and repeatedly adjusted exceptional costs can also complicate the apparent denominator.

Use P/E where earnings are meaningful

P/E can be useful for mature profitable companies with reasonably comparable accounting and capital structures. For some financial businesses, equity-based approaches may be more natural than a standard industrial-company EV/EBITDA framework because debt is integral to operations.

A low P/E can reflect cyclically high earnings about to fall; a high P/E can reflect temporarily depressed earnings or optimistic growth expectations. For negative earnings, a negative P/E does not mean the stock is an ordinary bargain. Use a method that fits the business and explain why the usual ratio fails.

Choose several complementary measures and inspect the actual business drivers. A hypothetical company at 8× EBITDA is not automatically better value than one at 12× if the former requires much more reinvestment or faces greater risk. Current peer comparisons need dated primary filings and market data. This educational example establishes calculation mechanics rather than a trade recommendation or a verified sector ranking.

Quick questions, clear answers

Is EV/EBITDA a cash-flow multiple?

It is often used as a rough operating comparison, but EBITDA is not free cash flow. It omits taxes, working-capital changes and capital expenditure. Reconcile it to operating cash and reinvestment before drawing conclusions about the cash available to investors.

Should I compare trailing and forward P/E?

They answer different questions. Trailing uses reported earnings; forward uses an estimate that may be wrong. Show both where useful, identify the forecast period and source, and avoid comparing one company's forward ratio with another's trailing ratio as though the bases match.

Which ratio should decide an investment?

Neither should decide it alone. Use ratios to identify questions, then assess the quality and sustainability of earnings, balance-sheet risk, management, valuation assumptions and suitability. An attractive multiple cannot by itself compensate for unreliable accounts or a deteriorating business.
