How to value a company: a beginner's guide
A plain-language introduction to company valuation: the three main approaches — multiples, discounted cash flow, and net assets — and when to use each.

Valuing a company means estimating what it is really worth — so you can judge whether the market price is a bargain, fair, or expensive. There is no single perfect method; professionals use three complementary approaches.
1. Relative valuation (multiples)
The fastest approach: compare the company to similar businesses using multiples such as the P/E ratio or EV/EBITDA.
If comparable companies trade at 15× earnings and your company trades at 10×, it may be undervalued — or the market may expect it to grow more slowly. Multiples are quick but only as good as the peers you compare against.
2. Discounted cash flow (DCF)
The most rigorous approach. A DCF estimates value as the free cash flow the company will generate in the future, discounted back to today’s value.
The logic: a euro received in ten years is worth less than a euro today, so future cash is “discounted” to reflect time and risk.
A DCF forces you to think about growth, margins and risk — but it’s highly sensitive to your assumptions. Small changes in the growth rate swing the answer a lot.
3. Asset-based valuation
Here you value the company by its net assets — what it owns minus what it owes, from the balance sheet. It’s most useful for asset-heavy businesses (property, banks) and as a floor value, less so for companies whose worth is mostly intangible.
Putting it together
Good analysts don’t rely on one number. Triangulate: sanity-check a DCF against multiples, and multiples against the balance sheet. The goal isn’t false precision — it’s a well-reasoned range, and the discipline to only buy with a margin of safety below it.
