What this Pokémon HP calculator does
This tool calculates a Pokémon's final HP stat using the standard main-series stat formula. It is useful for casual play, nuzlockes, competitive team building, and checking EV/IV training outcomes quickly.
Unlike Attack, Defense, and Speed, HP is not affected by nature. That means your HP result depends on only four things: base HP, IV, EV, and level (plus one special case: Shedinja).
Pokémon HP formula
If the Pokémon is Shedinja, HP is always 1.
Quick variable guide
- Base: Species base HP stat from the Pokédex.
- IV: Hidden individual value from 0 to 31.
- EV: Trained effort value, usually 0 to 252 in one stat.
- Level: Current level, from 1 to 100.
How to use the calculator
- Enter your Pokémon's Base HP.
- Set your Level.
- Enter HP IV and HP EV.
- Click Calculate HP.
The result panel shows the final HP stat and a full breakdown of each step, plus a min/max HP range at the same level for that base stat.
Example calculations
Example 1: Level 50 competitive spread
Suppose your Pokémon has base HP 95, level 50, IV 31, and EV 252.
floor(EV/4) = floor(252/4) = 632 × Base + IV + EV part = 190 + 31 + 63 = 284floor((284 × 50) / 100) = 142- Final HP =
142 + 50 + 10 = 202
Example 2: Story mode level 100
At level 100, the formula becomes easier to estimate because multiplying by level and dividing by 100 simplifies directly:
HP = (2 × Base + IV + floor(EV/4)) + 110
This is why level 100 stat planning feels very direct compared with level 50 formats.
Common HP planning targets in team building
| Target | Why players use it |
|---|---|
| High raw HP | General bulk and better survivability against neutral hits. |
| 4n + 1 HP | Often preferred with Substitute so the 4th Substitute can still leave 1 HP. |
| Hazard-aware HP numbers | Can optimize survivability around Stealth Rock and chip damage thresholds. |
| Balanced HP + defenses | Sometimes adding Defense/Sp. Def EVs gives better effective bulk than max HP alone. |
Important notes and mistakes to avoid
- HP EVs above 252 are not legal in standard play.
- Total EVs across all stats cannot exceed 510 (this calculator only checks HP EV).
- Nature does not change HP.
- Shedinja always has 1 HP regardless of level, IVs, or EVs.
- In-game rounding matters: the formula uses floor operations.
FAQ
Does this work for every generation?
It matches the standard modern main-series HP formula used in competitive contexts. Very old generation edge cases and battle-specific modifiers are outside this quick calculator.
Can this replace an IV calculator?
Not completely. This page computes HP from known values. An IV calculator usually infers IVs from observed stats, level, and nature.
Why do I get the same HP when EV changes by 1 point?
Because HP uses floor(EV / 4). In practice, EVs typically influence stats in chunks of 4.
Final takeaway
If you care about Pokémon optimization, HP math is one of the highest-value things to learn. Use this Pokémon HP calculator to test level 50 and level 100 builds quickly, compare min/max ranges, and tune EV spreads with confidence.
