Valuation multiples are the bread and butter of investment banking. Whether you’re pitching a deal, building a comparable companies analysis, or answering interview questions, you need to understand the most common multiples inside and out. In this guide, we’ll cover the three most important valuation multiples — EV/EBITDA, EV/Revenue, and P/E — including when to use each one, how to interpret them, and what interviewers expect you to know.
Before diving in, make sure you have a solid understanding of enterprise value vs. equity value — it’s the foundation for understanding why certain multiples use enterprise value in the numerator while others use equity value.
Enterprise Value Multiples vs. Equity Value Multiples
The most important concept to grasp is the distinction between enterprise value (EV) multiples and equity value multiples. The fundamental rule is simple: the numerator and denominator must be consistent.
- Enterprise value multiples use EV in the numerator and a metric available to all capital providers (debt + equity) in the denominator. Examples: EV/EBITDA, EV/EBIT, EV/Revenue.
- Equity value multiples use equity value (market cap or share price) in the numerator and a metric available only to equity holders in the denominator. Examples: P/E, Price/Book, Price/Cash Flow.
Why does this matter? EBITDA, EBIT, and revenue are all “pre-debt” metrics — they’re available to both debt and equity holders. Net income, on the other hand, is “post-debt” because interest expense has already been deducted. Mixing these up (e.g., using EV/Net Income) would produce a meaningless ratio because the numerator and denominator represent claims to different groups. For a deeper look at this distinction, check out our guide on enterprise value vs. equity value.
EV/EBITDA: The Workhorse Multiple
What Is EV/EBITDA?
EV/EBITDA divides a company’s enterprise value by its earnings before interest, taxes, depreciation, and amortization. It’s the most commonly used valuation multiple in investment banking for good reason — it’s capital-structure-neutral, tax-neutral, and removes the impact of non-cash charges like D&A.
When to Use EV/EBITDA
- Comparing companies with different capital structures — Since EBITDA is a pre-interest metric, it’s not affected by how much debt a company has.
- Comparing companies across tax jurisdictions — EBITDA is pre-tax, so differences in tax rates don’t distort the comparison.
- Capital-intensive industries — EBITDA adds back D&A, which makes it useful when comparing companies with different depreciation policies or asset ages.
- M&A transactions — Acquirers care about the cash flow available to service the deal’s debt, and EBITDA is a proxy for operating cash flow before capex.
Typical EV/EBITDA Ranges
EV/EBITDA multiples vary widely by industry:
- Technology (SaaS): 15x-30x+ (high growth, recurring revenue)
- Healthcare: 12x-20x
- Consumer/Retail: 8x-14x
- Industrials: 7x-12x
- Energy: 5x-8x
- Financials: Generally not used (EBITDA is less meaningful for banks)
Limitations
EV/EBITDA ignores capital expenditures, working capital changes, and differences in D&A policies. Two companies with the same EV/EBITDA might have very different free cash flow profiles if one requires significantly more capex. Also, EBITDA can be manipulated through aggressive revenue recognition or capitalization of operating expenses.
EV/Revenue: For When Earnings Don’t Exist
What Is EV/Revenue?
EV/Revenue divides enterprise value by total revenue. It’s the simplest valuation multiple and is most useful when profitability metrics are unreliable or non-existent.
When to Use EV/Revenue
- Unprofitable companies — Early-stage or high-growth companies with negative EBITDA and net income can only be valued on a revenue basis.
- SaaS and tech companies — Investors often focus on revenue growth and revenue quality (recurring vs. one-time) rather than current profitability.
- Cross-industry comparisons — When comparing companies with vastly different margin profiles, EV/Revenue provides a top-line comparison.
- Turnaround situations — If a company’s margins are temporarily depressed, revenue may be a more stable reference point.
Typical EV/Revenue Ranges
- High-growth SaaS (40%+ growth): 10x-25x+
- Moderate-growth SaaS: 5x-12x
- Technology (non-SaaS): 2x-6x
- Consumer/Retail: 0.5x-2x
- Industrials: 0.5x-1.5x
Limitations
EV/Revenue completely ignores profitability. A company trading at 3x revenue with 50% margins is fundamentally different from one at 3x revenue with 5% margins. Always use EV/Revenue alongside profitability-based multiples when possible.
P/E: The Equity Multiple Everyone Knows
What Is P/E?
The price-to-earnings ratio (P/E) divides a company’s share price by its earnings per share (EPS) — or equivalently, divides its market capitalization by its net income. It’s the most widely quoted valuation metric in financial media and equity research.
When to Use P/E
- Comparing companies within the same industry and similar capital structures — P/E works best when leverage and tax rates are comparable.
- Equity research — Analysts use P/E for target price calculations because investors think in terms of share prices and earnings.
- Mature, profitable companies — P/E is most meaningful for stable businesses with predictable earnings.
- Financial institutions — Banks and insurance companies are typically valued on P/E (or Price/Book) rather than EV/EBITDA because EBITDA is not a meaningful metric for financial companies.
Typical P/E Ranges
- S&P 500 average: 18x-22x (historically)
- High-growth tech: 30x-50x+
- Financials: 10x-15x
- Utilities: 15x-20x
- Cyclical industrials: 10x-18x
Limitations
P/E is distorted by differences in capital structure (high leverage inflates P/E due to lower net income from interest expense), tax rates, and non-recurring items. It also doesn’t work for companies with negative earnings. And because it’s an equity value metric, it doesn’t account for debt — two companies with the same P/E but different leverage levels have very different total valuations relative to their earnings power.
Forward vs. Trailing Multiples
You’ll encounter both forward and trailing (also called “LTM” for last twelve months) multiples:
- Trailing (LTM) multiples use actual historical financial data from the last twelve months. They’re factual and verifiable but backward-looking.
- Forward (NTM) multiples use consensus analyst estimates for the next twelve months. They’re more relevant for fast-changing businesses but rely on estimates that may be wrong.
In investment banking, forward multiples are generally preferred because buyers are paying for future earnings, not past performance. However, LTM multiples are also used — especially in transaction comps — because they’re based on actual results rather than projections. The best analysis presents both.
What Makes a Multiple “Good” or “Bad”?
There’s no universal answer to “what’s a good EV/EBITDA multiple?” — it entirely depends on context. Here’s what drives multiples higher or lower:
- Growth rate — Higher expected growth justifies higher multiples.
- Margins — Higher margins (or expanding margins) command premium multiples.
- Recurring revenue — Predictable revenue streams (SaaS subscriptions, long-term contracts) reduce risk and increase multiples.
- Market position — Market leaders trade at a premium to followers.
- Capital intensity — Asset-light businesses typically trade at higher multiples.
- Cyclicality — Cyclical businesses trade at lower multiples to reflect earnings volatility.
- Interest rate environment — Lower rates generally support higher multiples (lower discount rates increase present values).
The key in an interview is to avoid giving a blanket answer. Instead, frame your response around the specific industry, growth profile, and risk characteristics of the company in question.
Common Interview Questions About Valuation Multiples
- “Why do we use EV/EBITDA instead of P/E?” — EV/EBITDA is capital-structure-neutral, making it better for comparing companies with different leverage. P/E is affected by interest expense and therefore distorted by capital structure differences.
- “When would you use EV/Revenue?” — When the company is unprofitable or when margins are temporarily depressed. It’s common for high-growth tech/SaaS companies.
- “A company has an EV/EBITDA of 15x while the industry average is 10x. Is it overvalued?” — Not necessarily. It could be growing faster, have higher margins, better management, or stronger market position. You need to understand the qualitative reasons behind the premium.
- “Why is it wrong to use EV/Earnings or P/EBITDA?” — These mix capital-structure-neutral numerators with capital-structure-dependent denominators (or vice versa). EV goes with pre-interest metrics; equity value goes with post-interest metrics.
- “Walk me through how you’d build a comparable companies analysis.” — Select comparable companies, gather financial data, calculate relevant multiples (EV/EBITDA, EV/Revenue, P/E), take medians, apply to the target’s metrics to derive an implied valuation range. This requires understanding how the three financial statements link together.
Putting It All Together
Mastering valuation multiples means understanding not just the math, but the intuition. You need to know which multiples to use in different situations, what drives multiples higher or lower, and how to interpret them in context. This is foundational knowledge that comes up in nearly every investment banking interview — and on the job every single day.
