Pokemon Stat Formula Explained

The official Pokémon stat formula uses base stats, Individual Values (IVs), Effort Values (EVs), level, and nature to compute the final visible numbers in battle.

HP = floor( ( (2 × Base + IV + floor(EV/4)) × Level/100 ) + Level + 10 )
Other Stat = floor( ( (2 × Base + IV + floor(EV/4)) × Level/100 + 5 ) × Nature )

Nature multiplier is 1.1 for the boosted stat, 0.9 for the reduced stat, and 1.0 otherwise. HP is never affected by nature.

How Pokemon Stats Are Calculated Step by Step

  1. Obtain base stats – these are species‑specific values (e.g., Pikachu’s base Speed is 90).
  2. Set level – the Pokémon’s current level (1‑100) directly scales the final stats.
  3. Enter IVs – each stat has a fixed Individual Value (0‑31) determined at birth.
  4. Enter EVs – Effort Values are earned through training, up to 252 per stat (510 total). Every 4 EVs give 1 extra point at level 100.
  5. Choose a nature – nature raises one stat by 10% and lowers another by 10% (except HP).
  6. Apply the formula – for each stat, plug values into the appropriate formula and round down.

Pokemon Stat Calculation Examples

Example 1: Charizard (Level 50, 31 IVs, 0 EVs, Modest nature)

Base Sp. Atk = 109, Modest nature boosts Sp. Atk by 1.1×, lowers Attack by 0.9×.

Sp. Atk = floor( ( (2×109 + 31 + floor(0/4)) × 50/100 + 5 ) × 1.1 ) = floor( ( (218+31) × 0.5 + 5 ) × 1.1 ) = floor( 129.5 × 1.1 ) = 142

Example 2: Blissey (Level 100, 31 IV HP, 252 EVs HP, neutral nature)

Base HP = 255.

HP = floor( ( (2×255 + 31 + floor(252/4)) × 100/100 ) + 100 + 10 ) = floor( 510+31+63 + 110 ) = 714

Understanding IVs, EVs, and Natures

Individual Values (IVs) are innate genetic potential (0‑31 per stat). They cannot be changed after a Pokémon is caught or hatched (except with Hyper Training in later games).

Effort Values (EVs) are gained by defeating specific Pokémon or using vitamins. A maximum of 252 EVs can be invested in a single stat, and 510 total across all stats. Every 4 EVs contribute 1 stat point at level 100.

Natures permanently raise one stat by 10% and lower another by 10% (except the five neutral natures). Common competitive natures include Timid (+Spe, ‑Atk) for special sweepers and Adamant (+Atk, ‑SpA) for physical attackers.

People Also Ask About Pokemon Stats

Pokémon stats follow a fixed formula: for HP: floor(( (2×Base+IV+floor(EV/4)) × Level/100 ) + Level + 10). For other stats: floor(( (2×Base+IV+floor(EV/4)) × Level/100 + 5 ) × Nature). Nature gives 1.1× boost to one stat and 0.9× reduction to another (HP unaffected).
IVs (Individual Values) are fixed 0‑31 values set at birth, representing genetic potential. EVs (Effort Values) are earned through training, up to 252 per stat and 510 total. Both increase stats, but IVs are permanent while EVs can be reset and retrained.
Nature applies a 1.1× multiplier to one stat (except HP) and a 0.9× multiplier to another. The five stats that can be affected are Attack, Defense, Sp. Atk, Sp. Def, and Speed. A neutral nature leaves all stats unchanged.
Yes. This calculator works for any Pokémon from Generation III onward. Simply enter the base stats manually or select from the pre‑loaded list. The formula has remained consistent across all modern games.
Base stats are species‑specific values that define a Pokémon’s potential. For example, Mewtwo has 154 base Sp. Atk. They are combined with IVs, EVs, level, and nature to produce final battle stats. Higher base stats generally mean stronger Pokémon.

Frequently Asked Pokemon Stat Questions

Yes. The stat formula has been identical since Generation III. You can manually enter base stats for any Pokémon from any generation, or choose from a list of popular species.
Base stats are listed on official Pokémon databases, fan sites like Bulbapedia, or within the game’s Pokédex in some titles. Our dropdown includes many common species; simply select one to auto‑fill the values.
The calculator enforces per‑stat maximums of 252 but does not enforce the 510 total – it’s up to you to ensure your EV spread is legal. The game will prevent you from exceeding 510 total EVs.
HP uses a separate formula because it scales differently with level – it adds both Level and a constant +10 to ensure all Pokémon have at least 11 HP. Nature also does not affect HP.
Absolutely. The formula used is the exact in‑game calculation. Competitors use identical math to plan EV spreads and nature choices. Always double‑check with an in‑game stat checker for final verification.

Pokemon Stat Glossary

Base Stat

The species‑specific value for each stat, ranging from 1 to 255. Determines the fundamental potential of a Pokémon.

Individual Value (IV)

A fixed 0‑31 value per stat assigned at a Pokémon’s creation. Higher IVs yield higher final stats.

Effort Value (EV)

Points earned through battling, vitamins, or training that boost a stat. Maximum 252 per stat, 510 total.

Nature

A personality trait that multiplies one stat by 1.1 and another by 0.9 (except HP). 25 possible natures.

Level

The Pokémon’s current experience level (1‑100). Stats scale proportionally with level.

HP Stat

Calculated separately: floor(( (2×Base+IV+floor(EV/4)) × Level/100 ) + Level + 10). Nature never affects HP.

Stat Formula

The mathematical rule that converts base stats, IVs, EVs, level, and nature into final visible stats.

Floor Function

Always rounds down to the nearest whole number after each calculation step, matching in‑game behavior.

Editorial Review & Methodology

This Pokemon Stat Calculator was built and verified by the NumbrWiz Editorial Team. The stat formula implementation follows the official Pokémon core series calculations used from Generation III onward.

  • Formula verification: Cross‑checked against official game mechanics, community resources (Bulbapedia, Smogon), and independent testing.
  • Edge case testing: Validated with minimum/maximum values, level 1 and 100, and all natures.
  • UX design: Built for accessibility with clear validation, keyboard navigation, and screen‑reader support.

Transparency note: All calculations run entirely in your browser. No Pokémon data is ever collected, stored, or transmitted. This is an unofficial fan tool; results are for planning purposes only. Always verify with in‑game stats.
