Pokémon Type Calculator

How to use the Pokémon type calculator

This Pokémon type calculator checks a single or dual typing. It separates defense from offense so you can see both the damage a typing receives and the matchups its own attacks create.

1. Choose one type for a single-type matchup, or add a second type for a dual-type calculation.
2. Read the defensive result to find weaknesses, resistances, double weaknesses, double resistances, and immunities.
3. Check the offensive result to see what each selected attack type hits for increased, reduced, or zero damage.

How to read type effectiveness

In defensive results, each multiplier compares incoming damage with a neutral hit. The calculator groups the non-neutral results so the most important matchups are visible first.

How dual-type matchups are calculated

A dual-type calculation multiplies the two defensive modifiers for each incoming attack. Two 2× weaknesses become 4×. Two ½× resistances become ¼×. A 2× weakness and a ½× resistance cancel to the neutral 1× multiplier. If either selected type is immune, the combined defensive result is 0×.

This multiplication is why adding a second type can change a matchup substantially. It can create a double weakness, remove an existing weakness, strengthen a resistance, or add an immunity. The calculator performs that calculation separately against every possible attacking type before grouping the results.

Defense and offense answer different questions

The defensive card combines both selected types into one profile. It answers what deals extra damage to that typing, what it resists, and what cannot damage it through standard type effectiveness.

The offensive cards evaluate each selected attack type separately. They show which defending types take super-effective, reduced, or no damage from that type. They do not calculate exact battle damage, because move power, stats, same-type attack bonus, items, abilities, and field effects are outside this tool.

Pokémon type calculator vs. type chart

The type chart above shows every matchup at once: 324 of them, one for each pair of attacking and defending types. Most are neutral. 51 are super effective, 61 are not very effective, and 8 have no effect at all. The Pokémon type calculator applies the same chart to the one or two types you choose and returns only the matchups that matter, so use the chart to scan and the type calculator for a specific typing.

A few things stand out once the chart is laid out in full. Grass and Rock are weak to five types each, more than any other type, while Normal and Electric are weak to only one. Steel is the best defensive type: it resists or is immune to 11 of the 18. The eight immunities are Normal and Fighting against Ghost, Ghost against Normal, Electric against Ground, Ground against Flying, Poison against Steel, Psychic against Dark, and Dragon against Fairy.

This calculator evaluates one typing at a time. To compare several team members or attack types together, use the Pokémon type coverage calculator.
