Pokemon GO IV Calculator

The Pokemon GO IV calculator reveals the hidden Individual Values behind every Pokemon you catch — the Attack, Defense, and Stamina scores (each 0–15) that determine how strong your Pokemon truly is, regardless of CP. IVs are fixed at capture and cannot be changed, making them the single most important factor when selecting raid attackers, PvP picks, and Pokemon worth powering up to Level 50.

A 100% IV Pokemon has 15 in all three stats — the theoretical ceiling — while a 0% IV Pokemon scores zero across the board. In practice, anything above 80% is generally worth investing Stardust in for PvP, while raid meta Pokemon ideally need 90%+ to stay competitive at the top level. Check the CP calculator to see exactly how much CP your Pokemon will reach after powering up, and use the Stardust calculator to plan your upgrade costs before committing resources.

IVs interact directly with the CP Multiplier (CPM) at each level to determine final Combat Power, Hit Points, and battle performance. A perfect 15/15/15 Mewtwo at Level 40 reaches 4178 CP — versus a 10/10/10 Mewtwo hitting only 3982 CP — a difference that matters in difficult raids and Master League battles. Use the Pokemon GO IV calculator above to instantly reveal every stat, PvP rank, and level-by-level CP table for any Pokemon in your collection. Browse all our tools at the Pokemon calculators hub.

Type your Pokemon's name in the Search Pokemon box — results appear as you type. Click your Pokemon's name to select it. The sprite, type badges, and base stats load automatically.

Enter your Pokemon's Attack IV, Defense IV, and Stamina IV (each 0–15). If you have appraised your Pokemon in-game, use the Appraisal tab to input your Team Leader's arrow ratings instead — the calculator narrows down possible IVs automatically.

Set the Level slider to your Pokemon's current level. You can find the exact level by checking the arc above your Pokemon in-game — it moves from Level 1 (far left) to your trainer level +10 (far right). Half-levels are supported (e.g. 20.5).

Hit Calculate IVs. The results card instantly shows IV percentage, star rating, CP and HP at the current level, PvP league ratings for Great, Ultra and Master League, best moveset DPS, and a full CP table across every level from 1 to 50.

Individual Values in Pokemon GO work differently from the main-series games. Rather than six stats, Pokemon GO uses three: Attack, Defense, and Stamina. Each ranges from 0 to 15, giving 16 × 16 × 16 = 4,096 possible IV combinations per Pokemon species. The calculator above checks all combinations against your input to return the exact result.

The CP Formula

Combat Power is not a direct stat — it is a composite value derived from base stats, IVs, and the CP Multiplier (CPM) at the Pokemon's current level. The official formula is:

CP = (BaseAtk + IVAtk) × √(BaseDef + IVDef) × √(BaseSta + IVSta) × CPM² ÷ 10

The CPM is a level-dependent scalar value that increases from 0.094 at Level 1 to 0.8403 at Level 40 and 0.8740 at Level 50. This is why powering up a Pokemon raises its CP even without changing the IVs — the multiplier grows. Verify any result instantly with the IV calculator above.

Why IVs Matter (and When They Don't)

For casual play and raids below Level 5 difficulty, IVs have minimal impact — a 51% Pokemon can still win Tier 1 raids. The difference becomes significant in three scenarios: Master League PvP (where you fight at full CP and a 15/15/15 is always better), high-level raids (where a 100% attacker saves a few seconds off the clock), and friendship-powered duo raids (where every stat point counts).

For Great League (CP cap 1500) and Ultra League (CP cap 2500), the meta is counterintuitive: low Attack IVs are often better. Because CP is weighted more heavily toward Attack in the formula, a lower Attack IV lets you power a Pokemon to a higher level within the CP cap — gaining more Defense and Stamina stat product than a 15 Attack IV version at the same CP ceiling. This is why a 0/15/15 Medicham can outperform a 15/15/15 in Great League.

Common Misconceptions

Many players assume a shiny Pokemon has better IVs — it does not. Shininess and IVs are completely independent. Similarly, Lucky Pokemon obtained through trading are guaranteed a minimum of 12 in all three IVs, but they are not guaranteed 15/15/15. Purified Pokemon receive a +2 IV bonus applied before the 15 cap — so a 13/13/13 shadow becomes 15/15/15 when purified, making mid-IV shadows worth keeping.

Weather-boosted catches also have a minimum IV floor of 4 in all three stats. Research breakthrough and raid boss catches start at a minimum of 10/10/10. Eggs and hatches have a minimum of 10/10/10 as well. Knowing these floors helps you quickly reject or keep Pokemon without needing a calculator every time.
