Pokemon Health Calculator

Calculate a Pokemon's health points (HP) using its base stats, Individual Values (IVs), and Effort Values (EVs). This calculator helps trainers determine the maximum potential HP of their Pokemon and understand how IVs and EVs affect its health.

How to Use This Calculator

To calculate a Pokemon's HP:

Enter the Pokemon's base HP stat (found in the Pokedex).
Enter the Pokemon's IVs (Individual Values) for HP. Each IV ranges from 0 to 31.
Enter the Pokemon's EVs (Effort Values) for HP. Each EV ranges from 0 to 252.
Select the Pokemon's level (1-100).
Click "Calculate" to see the results.

The calculator will display the calculated HP, the minimum and maximum possible HP for that Pokemon, and a chart showing the HP growth at different levels.

Formula Explained

The formula for calculating a Pokemon's HP is:

HP = floor(0.01 × (2 × Base + IV + floor(0.25 × EV)) × Level) + Level + 10

Where:

Base - The Pokemon's base HP stat from the Pokedex
IV - Individual Value for HP (0-31)
EV - Effort Value for HP (0-252)
Level - The Pokemon's current level (1-100)

The minimum HP occurs when IV = 0 and EV = 0, while the maximum HP occurs when IV = 31 and EV = 252.

Worked Example

Let's calculate the HP for a level 50 Charizard with:

Base HP: 78
IV: 31
EV: 252

Using the formula:

HP = floor(0.01 × (2 × 78 + 31 + floor(0.25 × 252)) × 50) + 50 + 10

= floor(0.01 × (156 + 31 + 63) × 50) + 60

= floor(0.01 × 250 × 50) + 60

= floor(125) + 60

= 125 + 60

= 185

So, this Charizard has a calculated HP of 185.

Frequently Asked Questions

What are IVs and EVs?: IVs (Individual Values) are hidden stats that determine a Pokemon's potential. EVs (Effort Values) are points that can be trained to increase a Pokemon's stats. Both affect a Pokemon's HP calculation.
How do I get better IVs?: IVs are randomly determined when a Pokemon is caught. There's no way to directly improve them, but you can breed to pass on favorable IVs to offspring.
What's the maximum HP for a Pokemon?: The maximum HP occurs when a Pokemon has 31 IVs and 252 EVs in HP. This gives the highest possible HP value for that species.
Does level affect HP?: Yes, HP increases with level. The formula accounts for this by multiplying the base calculation by the current level.
Can I use this calculator for all generations?: This calculator uses the modern formula that applies to Generation III and later. For older generations, the formula differs slightly.
