When would you use DCF vs comps (With Examples): Interview Answer Guide 2027

This dcf vs comps interview question is best shown on one hypothetical company. Your DCF says $50 per share; trading comps at a 10x EV/EBITDA median say $48. The $2 gap is the interesting part — either your forecasts are optimistic or the market is mispricing the peers — and explaining which you believe is the real answer.

What This DCF vs Comps Interview Question Tests

A DCF and a comps analysis answer different questions. The DCF is an intrinsic valuation: it asks what the company is worth based on the cash it will generate, discounted for time and risk — independent of what the market thinks today.

How to Answer This DCF vs Comps Interview Question

Value a hypothetical packaging company both ways. Your DCF — 5% revenue growth, stable 15% EBITDA margins, 9% WACC, 2% terminal growth — produces an enterprise value implying $50 per share. Trading comps of four similar packaging firms sit at a median 10x EV/EBITDA; applied to this company's EBITDA, they imply $48 per share.

Now interpret the $2 gap instead of just reporting it. If your growth forecast exceeds what peers are achieving, the DCF may be optimistic and the comps are warning you. If the whole sector just sold off on macro fears while this company's contracts are locked in, the DCF may be seeing through noise the market is overreacting to.

Common Mistakes on the DCF vs Comps Interview Question

Declaring one method universally superior. “DCF is always better” (or the reverse) signals a student answer. Each has failure modes; professionals weight by context.

Running only one method. Answering a valuation question with a lone DCF or a lone comp multiple ignores the triangulation norm — interviewers will ask “what does the other approach say?”

Ignoring the story behind the gap. Reporting two numbers without explaining why they differ wastes the most valuable part of the exercise — the disagreement is the analysis.

This is the kind of technical question that commonly decides interview rounds — candidates report that one hesitant or rambling answer here can end the process on the spot. Practice saying your answer out loud until it sounds calm, structured, and confident.

FAQ

Can DCF and comps give very different answers?

Yes, and that is normal — they measure different things. A wide gap means either your assumptions diverge from market expectations or the market is mispricing the peers; investigating which is the real work.

Which is faster to build?

Comps, by far — a trading multiples table can be assembled in an afternoon, while a proper DCF needs a full forecast model. Speed is part of why comps dominate early-stage screening.

Do professionals really use DCFs if they're so sensitive?

Yes, but as one input among several, usually with sensitivity tables and scenario analysis rather than a single point estimate. The discipline of building the forecast is often as valuable as the output.

Where do precedent transactions fit in?

As a third leg, especially in M&A: they show multiples buyers actually paid, including control premiums. Interview format may vary by role and region — check the official careers page for the current process.
