Forward PE Calculator

Work out forward pe instantly with clear inputs, formula shown and shareable results.

About Forward PE Calculator

Forward P/E divides price by expected earnings, so growth pulls the multiple down relative to the trailing figure. The PEG ratio then compares that multiple with the growth rate, a rough test of whether growth is already in the price.

Formula

Forward multiples

Forward EPS = EPS × (1+g); Forward P/E = price / forward EPS; PEG = P/E ÷ growth %

Worked example

With the default values below, Forward PE Calculator returns Forward Price To Earnings of 25.424. Change any input above and every figure here is recalculated in your browser.

  • In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
  • Figures are rounded for display to 3 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.
  • Figures are estimates for planning only. Market returns are not guaranteed, and rates, limits and tax rules change. This is not financial or tax advice — speak to a qualified adviser before acting.
  • This is an estimate for general information and not professional financial, tax or legal advice. See the full disclaimer for the limits that apply to this kind of calculator.

Frequently Asked Questions

How reliable are forward estimates?

They are forecasts and are usually too optimistic, so treat a low forward P/E built on aggressive growth with care.

What PEG is considered reasonable?

Around 1 is the traditional rule, though it breaks down for very high or negative growth rates.
