Forward Price-to-Earnings (P/E) Ratio: Definition and Example

The forward price-to-earnings (P/E) ratio compares a stock’s current share price with expected future earnings per share, usually over the next year.

It is a forward-looking valuation metric, unlike a trailing P/E ratio, which uses earnings already reported.

How It Works

A simple form is:

current share price / expected next-year earnings per share

Because the denominator is forecasted, the ratio can change sharply when analyst estimates or company guidance change.

Worked Example

Suppose a stock trades at $72 and analysts expect next year’s earnings per share to be $6.

Its forward P/E ratio is:

$72 / $6 = 12

If the earnings forecast falls to $4.80, the forward P/E immediately rises to 15, even though the share price has not moved.

Scenario Question

An investor says, “Forward P/E is always more reliable than trailing P/E because it uses future earnings.”

Answer: Not necessarily. It may be more relevant, but it is also more dependent on forecast accuracy.
