# What is a pokemon's "Level" and its purpose?

I am using this IV calculator by the SilphRoad Community to compute IV values. Recently, I managed to have two Pinsirs with the same Perfect Percentage, as shown here:

As you can see, both Pinsirs have `95.6%` Perfect Value, and comparing their IV Values, they have `15-15` ATK, `14-15` DEF and `14-13` STA – not much of a difference I think? But I noticed the difference on the Pokemons' Level it is `26` to `20.5`. The tooltip says:

From that I assume that a Pokemon's level is proportion to how many times it takes to power up that Pokemon to reach its current CP. So is it just another description of a Pokemon with no application in battling them?

What is a pokemon's "Level" and it's purpose? I hope you can also explain the difference in my example – why is it `20.5`-`26`?

• Is the assumption, that with infinite stardust and candies only the `% Perfect` column would be relevant, correct? Commented Aug 5, 2016 at 8:31
• @Mathias711 sadly the IV calc column of maxed Cp doesn't show the Max for both Pinsir, in your statement `Higher level means higher CP` does it mean, that those 2 Pinsir will have different CP when maxed? Commented Aug 5, 2016 at 11:20
