Why is the PE and PEG ratio on Simply Wall St platform different to other sites?

Simply Wall St uses trailing twelve months or “TTM” data excluding extraordinary items for all of our past net income and EPS figures.


Why is the PE ratio on the Simply Wall St platform different?

If you find that the PE ratio is different from other sites, please follow the steps outlined below:

  1. Check the EPS or earnings per share data used by other sites. Is it based on future earnings? In which case it would be a “forward P/E ratio” and therefore not comparable to the current P/E ratio (based on TTM EPS) on the SWS site. The same goes for when other sites use EPS  based on annual data which can be outdated.
  2. You can see the inputs used in the P/E calculation by clicking on view data under the PE section under “Valuation”.



  1. Compare the inputs in the SWS-calculated PE ratio to the data on other sites and this should help you see what is causing the difference.

Why is the PEG ratio on Simply Wall St platform different?

Our PEG ratio is calculated based on the most recent PE Ratio and updated EPS growth rate based on consensus analysts forecast. Other sites may show different PEG ratios as they might be using out-of-date EPS growth rates or figures that are based on historical data. Our PEG ratio is more up-to-date than others as it changes as the market price moves, when there are revisions on consensus analysts estimates or if there is a new earnings report which could affect PEG calculations. To know more about the frequency of each of these updates, check out How often is the financial data updated.

You can follow the similar steps outlined above to check the inputs used in our PEG calculation.
