Forward P/E

The same ratio against next year's expected earnings, so it depends on a forecast rather than a fact.

Updated 2026-09-03

How it is calculated

Forward P/E = price ÷ expected next-year EPS

The forward price-to-earnings ratio uses analysts' consensus estimate of next year's earnings rather than last year's actual result. It answers what you are paying against what the company is expected to earn.

It is more useful than the trailing figure for a business whose profits are genuinely changing, and less trustworthy, because the denominator is now an opinion. Consensus estimates are systematically optimistic, they cluster because analysts read each other, and they are revised sharply after the fact rather than before it.

The gap between trailing and forward P/E is often the more informative number. A large gap means the market expects a substantial change in profitability, and that expectation is exactly the thing a DCF should be tested against.

  • PEG — A P/E adjusted for how fast the company is growing. Around 1.0 is conventionally treated as fair, though the convention has little theory behind it.
  • EPS — Profit for the last twelve months divided by the share count. Accounting profit, not cash, which is why Angie values the cash instead.
