Valuation multiples come up in investment banking interviews in two forms: the direct question ("Which multiple would you use for this company?") and the bigger one, "How would you value this business?", where comparable companies analysis does much of the work. In both, the interviewer checks one thing first: do you know which value goes on top of which metric? Pair them wrongly and you lose the interviewer early, however polished the rest sounds.
What valuation multiples measure
A single multiple means little until you set it beside similar businesses, which is why bankers call this relative valuation. Two values can sit on top of the fraction.
- Enterprise value is the value of the operating business to everyone who funds it: shareholders, lenders, preferred holders and non-controlling interests, net of cash.
- Equity value is the common shareholders' slice. For a listed company, that is the share price times diluted shares outstanding.
The matching rule
The numerator and the denominator have to belong to the same group of capital providers. To test it, ask one question about the denominator: have the lenders been paid yet?
- Not yet (revenue, EBITDA, EBIT, unlevered free cash flow): lenders and shareholders both have a claim on it, so it pairs with enterprise value.
- Already paid (net income, EPS, levered free cash flow): interest has come out and the rest belongs to shareholders, so it pairs with equity value.
On the income statement, interest expense is the dividing line. Metrics above it go with enterprise value; metrics below it go with equity value. Our breakdown of EBIT vs EBITDA vs net income walks the income statement line by line.
The EV/Net Income trap
Take an illustrative example with round numbers, ignoring the tax benefit of debt. Two companies have identical operations: EBIT of 100, a 25% tax rate and an enterprise value of 750. Company A has no debt. Company B carries 300 of debt at 10% interest, so its equity value is 750 minus 300.
| Item | Company A | Company B |
|---|---|---|
| EBIT | 100 | 100 |
| Interest | 0 | 30 |
| Net income | 75 | 52.5 |
| Enterprise value | 750 | 750 |
| Equity value | 750 | 450 |
| EV/EBIT | 7.5x | 7.5x |
| P/E | 10.0x | 8.6x |
| EV/Net Income | 10.0x | 14.3x |
| Equity value/EBIT | 7.5x | 4.5x |
Illustrative round numbers. Net income is after interest and 25% tax; B's P/E and EV/Net Income are rounded to one decimal.
Now read the multiples.
- EV/EBIT is the same for both. The businesses are identical, and the multiple says so.
- P/E is lower for B, and the gap has a real cause: B's shareholders own a leveraged, riskier claim.
- EV/Net Income is higher for B, and nothing in B's operations justifies it. You divided everyone's claim by the shareholders' earnings: the top still counts B's lenders, while the bottom has already paid them.
- Equity value/EBIT is the mirror-image mistake. It fails in the other direction, making B look like a bargain only because it borrowed.
The valuation multiples you will see most
- EV/Revenue. Useful when a company has little or no profit, such as an early-stage or high-growth business. Its weakness: it treats a thin-margin company and a high-margin one as interchangeable.
- EV/EBITDA. The workhorse of comps. It sits above interest, so leverage does not distort it, and above D&A, so depreciation policy matters less. Its blind spot is capex: two businesses can show the same EBITDA while one spends far more of it on equipment.
- EV/EBIT. Captures D&A, which makes it a better yardstick when capital intensity varies across the peer set.
- P/E. The multiple equity investors quote. Leverage, interest and tax all feed into it, so it suits shareholders but gets noisy across different capital structures.
| Sector | EV/EBITDA | EV/EBIT |
|---|---|---|
| Semiconductors | 34.8x | 44.3x |
| System and application software | 24.5x | 32.4x |
| US market, excluding financials | 17.0x | 25.7x |
| Food processing | 10.0x | 13.6x |
| Telecom services | 6.5x | 12.2x |
| Oil and gas producers | 5.2x | 10.3x |

Two patterns stand out. Across these sectors EV/EBITDA runs from about 5x to 35x, so 12x can be cheap in one sector and expensive in another. And the step from EV/EBITDA to EV/EBIT is largest where D&A is heavy: oil and gas producers roughly double, while software rises by about a third.
Banks and insurers are the classic exception. Borrowing is part of their operating model, so enterprise value stops meaning much and you will see price-to-book and P/E instead. The dataset behind the table above reports no EV multiples for banks. Raising the exception unprompted shows you understand why the rule exists.
How comps put multiples to work
Comparable companies analysis applies the matching rule across a peer group.
- Pick the peer set. Similar sector, size, growth, margins and geography. This step carries more judgement than any formula in the analysis.
- Build each peer's numerators. Equity value from share price and diluted shares; enterprise value by adding debt, preferred stock and non-controlling interests and subtracting cash. For US-listed companies, the filings with these inputs are free on SEC EDGAR.
- Calculate multiples on consistent periods. Use last-twelve-months or forward figures for every peer, not a mix.
- Apply a range to the target. Take the range where the peers cluster and multiply it by the target's metric.
Precedent transactions apply the same multiples to prices paid in past deals, as our guide to precedent transaction analysis explains.
Follow-ups to have ready
"Can you use EV/Net Income?" No. Net income is after interest, so it belongs to shareholders, while enterprise value includes the lenders' claim. Say that in one sentence and stop.
"Two companies have the same EV/EBITDA but different P/E ratios. Why?" Different leverage, tax rates or D&A. Anything between EBITDA and net income can move P/E without touching EV/EBITDA.
"Which multiple would you use for a loss-making company?" EV/Revenue, or a forward EBITDA multiple if profits are in sight. A negative P/E tells you nothing.
"A company issues shares and uses the cash to repay debt. What happens to EV/EBITDA?" Ignoring fees, nothing: enterprise value and EBITDA both stay put. P/E usually changes, because equity value and net income both move.
A 30-second answer
"A valuation multiple divides a company's value by a financial metric so I can compare it with similar businesses. Both sides must belong to the same capital providers. Enterprise value belongs to debt and equity holders, so it pairs with metrics before interest, like revenue, EBITDA and EBIT. Equity value belongs to shareholders, so it pairs with metrics after interest, like net income. That is why EV/EBITDA and P/E work and EV/Net Income does not."
How to make it stick this week
- Say the 30-second answer out loud until you need no notes, then have someone fire the four follow-ups at you in random order.
- Rebuild the Company A and B example from memory with your own numbers. If EV/EBIT comes out the same for both, you have the logic.
- Calculate one real multiple. Compute a listed company's EV/EBITDA by hand from its latest annual report, then compare it with the free US sector figures in Aswath Damodaran's EV multiples dataset at NYU Stern, last refreshed in January 2026. If yours sits far from the sector, work out why.
