Price-to-earnings ratio: Reading a P/E Ratio in Context
Price-to-earnings compares share price with earnings per share. A lower multiple can reflect different growth expectations, accounting effects or business risk rather than an obvious bargain.
Use the Price-to-earnings ratio Calculator to enter your own figures and compare the result with the worked example below.

These are illustrative inputs, not current prices, rates or recommended targets. Where a currency is shown, keep all comparable money amounts in the same currency; conversion examples identify the two sides separately.
How to interpret the result
Compare compatible trailing or forward earnings. Negative or unusually small earnings limit the usefulness of the ratio.
