Instructions ±

What are IVs and EPs?

If such terms sound Greek to you, then you should read a Pokémon Training Guide before using this tool.

User Interface

Generates a SaveCode and a link (URL) that you can keep in your bookmarks or send to a friend.
Single click to load the data saved in the URL, or double-click to load any SaveCode.
Some random examples: Shuckle, Giratina, Snorlax and a team.

IV Calculation (make it look simpler?)

* Fields marked with an asterisk are optional.


Every calculator will return errors if your Effort Points are innacurate! If necessary, use some anti-vitamin berries.

Single mode: The higher your Pokémon's level, the more accurate the results. If you want to calculate a low level one, then input the optional information and additional row data by leveling-up, evolving it or changing forme. The +Lv. and +EPs indicators, tell you how many apitional levels or Effort Points (same level) respectively are required to refine the resulting IV spread.

The Judge guy is located in the Battle Tower's lobby, near the PC, and can tell you the potential of your Pokémon and the stat with the highest IV. Talk to him multiple times to find out if there's a tie in the highest IV.

You can practically get 100% accurate results at level 20, using just a few Rare Candies; save beforehand if you'd like to keep them of course.

Team mode: Useful for IV Battles; use this to calculate multiple Pokémon at once. For an IV Battle, gather a team of low level Pokémon and battle with a friend online, forcing them to level 100, then writing down their projected stats.

Row mode: Use this to calculate and examine currently selected Pokémon in detail.

Stat Calculation

Using the median IVs, and input Effort Points, accurately calculates a Pokémon's stats on the given level.

Hidden Power Calculation

Hidden Power's type and base power depend on a Pokémon's Individual Values.

Using the IV spread (or median IVs if locked) you can calculate all possible combinations.

The Hidden Power guy in the GameCorner Prize Building (Platinum: Veilstone, HeartGold/SoulSilver: Celadon, Black/White: Mistralton City) lets you know exactly what type it is. In previous games, attacking a Kecleon helps as well.

EV training tools

EP tracking
Unselect an active row to enable tracking mode, then select the proper item, opponent species and number fought, to calculate the Effort Points gained.
EPs Calculation
Particularly useful to competitive battlers.
First calculate your current Pokémon's stats, alter your current stats in the first row, then use this to view how many EPs are required to reach these specific stats.
