This tool helps you determine the exact Effort Values (EVs) required for a specific Pokémon to achieve a desired Stat Value at a given Level, IV, and Nature combination.

Pokémon EV Calculator Formula
The standard formula used to calculate a non-HP stat (Attack, Defense, Special Attack, Special Defense, Speed) in Pokémon is:
Where:
Formula Source: Bulbapedia: Stat Calculation | Serebii: Detailed Stat Mechanics
Variables
- S (Final Stat): The final stat value the Pokémon has in battle.
- BS (Base Stat): The stat value inherent to the Pokémon’s species.
- IV (Individual Value): A random number from 0 to 31 that contributes to the stat.
- E (Effort Value): The value (0 to 252) earned through training, always applied in multiples of 4. This is the value this calculator solves for.
- L (Level): The Pokémon’s current level.
- N (Nature Multiplier): 1.1 (Beneficial Nature), 1.0 (Neutral Nature), or 0.9 (Hindering Nature).

What is Effort Value (EV) Calculation?
Effort Value (EV) calculation is the process competitive players use to precisely allocate the 510 total EV points a Pokémon can earn, ensuring they hit specific stat breakpoints required for their role. For instance, a player might need their Speed stat to be exactly 1 point higher than a common threat (like another Pokémon’s maximum Speed stat) to guarantee moving first.
An EV calculator reverses the official stat formula. Instead of inputting the EVs and getting the resulting stat, you input your *desired* stat and the calculator tells you the minimum EVs you must invest. This is critical for optimizing builds and preventing wasted EV points, as 4 EVs are needed to get +1 stat point at level 100.
How to Calculate Required EVs (Example)
Suppose you are training a Pokémon (Level 50) with a Base Stat of 120 and 31 IVs, and you want its final stat to be exactly 150 using a Beneficial Nature (1.1).
- Identify Inputs: BS=120, IV=31, L=50, N=1.1, Target Stat=150.
- Set up the Loop: Start testing EV values from 0, 4, 8, … up to 252.
- Test EV=0: Calculate the stat with 0 EVs. If the result is less than 150, continue.
- Test EV=4: Calculate the stat with 4 EVs. If the result is less than 150, continue.
- Find Breakpoint: The calculator finds the lowest EV value (e.g., 204 EVs) where the resulting stat is 150 or higher. This is your required EV investment.
- Final Check: If, after testing 252 EVs, the stat is still below 150, the target is impossible under these conditions (Level, IV, and Nature are too low).
Frequently Asked Questions (FAQ)
Is the EV formula the same for all Pokémon stats? The formula for HP is slightly different (it includes a base HP calculation), but the formula used in this calculator is accurate for all five non-HP stats: Attack, Defense, Special Attack, Special Defense, and Speed.
What is the maximum EV I can allocate to one stat? The maximum Effort Value (EV) you can allocate to a single stat is 252. The total maximum EVs across all six stats is 510.
Why do EVs have to be in multiples of 4? For every 4 EVs invested in a stat, the Pokémon gains 1 stat point at Level 100. Investing 1, 2, or 3 EVs in a stat provides the same benefit as 0 EVs at Level 100, which is why EVs are always optimized in multiples of 4.
What is a ‘breakpoint’ in EV training? A breakpoint is the minimum stat value needed to achieve a specific game-play goal (like outspeeding a major threat or guaranteeing a 2HKO). The required EV is the lowest multiple of 4 that successfully reaches that breakpoint.
