How to compute the price-to-earnings (P/E) multiple

1. Enter share price

   "Share price" is the current (or quoted) price of one share. Same currency as the EPS you'll enter — the tool doesn't convert currencies.

2. Enter EPS

   "EPS" is earnings per share for the period you're using (trailing 12 months for TTM P/E, latest full year for annual). EPS = 0 throws "EPS cannot be 0." — a P/E multiple isn't meaningful at zero earnings.

3. Press Run

   Result is pe = price / eps, rounded to 4 decimals. Don't compare P/Es across sectors without context — utilities and tech sit in very different bands.

4. Negative P/E warning

   If EPS is negative (a loss), this returns a negative P/E. Most analysts treat negative P/E as "not meaningful" rather than a low multiple — losses don't get multiplied.
