Pokémon Stat Calculator (Gen 3+)
Use this tool to calculate a Pokémon stat from its Base Stat, Level, IV, EV, and Nature.
How a Pokémon Stat Calculator Works
A Pokémon stat calculator helps you predict your final in-battle stats before you spend time breeding, hyper training, EV training, or leveling. Instead of guessing whether your Speed is enough to outspeed a key threat, you can calculate the exact number and plan your build with confidence.
In modern games (from Generation 3 onward), stats are determined by five key factors: Base Stat, Level, IV, EV, and Nature. HP uses a slightly different equation than the other five stats.
Core Formulas (Gen 3+)
HP Formula
HP = floor(((2 × Base + IV + floor(EV/4)) × Level) / 100) + Level + 10
Other Stats Formula
Stat = floor((floor(((2 × Base + IV + floor(EV/4)) × Level) / 100) + 5) × Nature)
- Nature is 1.1 if boosted, 0.9 if lowered, and 1.0 if neutral.
- EV impact is reduced with floor(EV/4), so EV values not divisible by 4 can be inefficient.
- Shedinja is a famous exception: it always has 1 HP.
Understanding IVs, EVs, and Nature Quickly
IVs (Individual Values)
IVs are hidden values from 0 to 31 for each stat. Higher is better for most builds, with 31 often considered "perfect." Competitive players usually optimize IVs to hit exact benchmarks.
EVs (Effort Values)
EVs come from training and items, and they directly increase stats. A single stat can have up to 252 EVs, and total EVs across all stats are capped at 510. Because only EV/4 matters in the formula, efficient spreads use multiples of 4.
Nature
Nature modifies one non-HP stat by +10% and another by -10% (or does nothing if neutral). This can significantly change speed tiers and damage ranges, especially at level 50 in competitive formats.
Example Calculation
Suppose you want to calculate Speed for a level 50 Pokémon with Base 100, IV 31, EV 252, and a beneficial nature:
- floor(EV/4) = floor(252/4) = 63
- 2 × Base + IV + floor(EV/4) = 200 + 31 + 63 = 294
- floor((294 × 50) / 100) = floor(147) = 147
- 147 + 5 = 152
- floor(152 × 1.1) = floor(167.2) = 167
Final Speed = 167.
Why This Matters in Team Building
Stat planning is one of the biggest edges in both singles and doubles formats. Small differences like 1-2 points can decide who moves first or survives a key hit. Use a stat calculator when:
- Designing EV spreads around speed tiers
- Checking if a defensive spread survives specific attacks
- Comparing neutral vs. boosting nature options
- Optimizing level 50 and level 100 builds
Common Mistakes to Avoid
- Forgetting nature on non-HP stats
- Using inefficient EVs (for example, 250 instead of 252)
- Mixing level assumptions between formats (50 vs. 100)
- Ignoring special cases like Shedinja's fixed HP
Final Thoughts
A reliable Pokémon stat calculator removes guesswork from your builds. Once you understand the formulas, you can tailor every point to your strategy—whether you are climbing ranked battles, preparing for tournaments, or just building cleaner teams in casual play.
