Beginner Reading

When should you use the HP Calculator?

Burn, poison, sandstorm, Stealth Rock, Spikes, and healing items create HP breakpoints that matter when reading remaining health and tuning HP SP.

Open HP examples and tuning tips

Read remaining HP from the current HP.

Enter max HP and current HP to see what remains after status, hazard, weather, and recovery effects are applied.

Stealth Rock follows type effectiveness.

Stealth Rock is tied to Rock-type effectiveness, so Fire and Flying candidates can lose much more on entry.

HP SP optimization finds breakpoints.

Even with similar bulk, final HP values near 16n, 16n+1, or 4n can change residual damage and recovery amounts.

Examples

After Stealth Rock

Check whether a switch-in survives the next hit after taking entry damage.

Leftovers and Sitrus value

Compare HP SP candidates to find final HP values with better recovery efficiency.

Reading notes

  • Spikes only applies to grounded Pokemon.
  • Sandstorm and poison matter more when you read them across multiple turns.
  • Use the damage calculator for direct move damage.
