If you were looking for the in-battle stat, see Stats#Accuracy.

Accuracy is an aspect of moves that determine how often they can hit their target.

A move's base accuracy currently can be any number from 1-100, reflecting the probability of the move hitting as a percentage; moves' accuracy was not visible to the player until the Generation III games. While values from 1-100 for accuracy are possible, only values from 50-100 are used, and is only used in multiples of 5.

Many moves have an accuracy of "—%", indicating that they are exempt from accuracy calculations. This is usually because they affect no one but the user (and/or the partner in a Double Battle), or because they will never miss the target unless the target uses a move that grants semi-invulnerability for a turn (such Fly or Dig).

Accuracy can be increased by Abilities, held items, and increasing the accuracy stat; Compoundeyes raises the Pokémon's accuracy by 30%, Victory Star raises a Pokémon's accuracy by 10%, the Wide Lens raises the holder's accuracy by 10%, and the Zoom Lens raises the holder's accuracy by 20% if the holder moves after its target from Pokémon Platinum onwards. The accuracy stat can be increased by Acupressure, Hone Claws, Coil, Moody, and X Accuracy.

Accuracy can be decreased by Abilities, held items, and decreasing the accuracy stat; Hustle decreases the accuracy of the Pokémon's physical moves by 20%. The accuracy stat can be decreased by Flash, Kinesis, Mirror Shot, Mud Bomb, Mud-Slap, Muddy Water, Octazooka, Sand-Attack, SmokeScreen, and Secret Power when used in the sand, on plain terrainDPPtHGSS, and in puddlesDPPtHGSS.

Formula for accuracy and evasion

The probability that a move will hit is calculated as follows:

Accuracy calc.png

Where:

  • Abase is the base accuracy of the move (in percent - e.g. a base accuracy of 95 is counted as 0.95),
  • Accuracy is the current accuracy stat of the user (in percent - e.g. raising accuracy by three stages raises this number to 2), and
  • Evasion is the current evasion stat of the target (in percent - e.g. lowering evasion by two stages lowers this number to 0.6).

If P is greater than 1, the move will surely hit. In a Double or Triple Battle, it is possible for a move that targets multiple Pokémon to hit some and miss others—the probabilities are calculated individually for each Pokémon.

In Generation I

In the Generation I games, even moves with a 100% accuracy would miss once in a great while for seemingly no reason whatsoever. This was due to accuracy being internally calculated as a fraction of 256, when the highest internal accuracy a move could possess was 255 (FF in hexadecimal, and the highest value expressible in a single byte), yielding an accuracy of 99.6%. This also applied to secondary effects such as poison or paralysis, but it was resolved in Generation II.

In the Pokémon Mystery Dungeon series

In the Pokémon Mystery Dungeon series, accuracy is instead called "Hit Ratio" and is displayed with a number of stars instead of a numerical value. More stars indicates a higher accuracy. For example, Scratch has a Hit Ratio of PMD Star IV.pngPMD Star IV.pngPMD Star IV.pngPMD Star IV.pngPMD Star IV.pngPMD Star IV.pngPMD Star IV.png.

Hit Ratio does not correlate with accuracy from the main series. Some moves, such as Scratch and Crunch, share the same accuracy in the main series but have different Hit Ratios (or vice versa).
