Pokémon GO IV Calculator
Enter your Pokémon's individual values (IVs) from appraisal: Attack, Defense, and HP (Stamina), each from 0 to 15.
What this Pokémon GO IV calculator does
This tool quickly converts your Pokémon's three IV stats into an easy-to-read total IV percentage. In Pokémon GO, every Pokémon has hidden individual values for Attack, Defense, and HP (Stamina), each ranging from 0 to 15. These are added together to produce a value out of 45.
The calculator gives you:
- Total IV score (out of 45)
- IV percentage (0% to 100%)
- Star-style appraisal tier
- A practical recommendation for raids or PvP
How IVs work in Pokémon GO
IVs are permanent stats assigned to each Pokémon when you catch, hatch, or trade it. They affect final battle stats, but they are only one piece of the puzzle. Species, moveset, level, and type matchups usually matter even more.
IV range explained
- Attack IV: 0-15
- Defense IV: 0-15
- HP IV: 0-15
Maximum possible total is 45. The IV% formula is:
IV% = (Attack + Defense + HP) / 45 × 100
What counts as a “good” IV?
For many trainers, 90%+ is great. A perfect Pokémon has 15/15/15 (100%), often called a hundo. But in Great League and Ultra League PvP, lower Attack with high Defense/HP can actually perform better under CP caps.
How to use this IV calculator
- Open your Pokémon's appraisal screen in Pokémon GO.
- Read the exact IV bars (or values if known from scanning tools).
- Enter Attack, Defense, and HP values in the calculator.
- Click Calculate IV % to see your result.
Understanding your result
The result includes a star-equivalent bracket similar to in-game ranges:
- 4★: 45/45 only (100%)
- 3★: 37-44 total
- 2★: 30-36 total
- 1★: 23-29 total
- 0★: 0-22 total
Use this as a fast decision helper when choosing what to power up, evolve, transfer, or keep for league play.
Raid vs PvP IV priorities
For raids and gym offense
Higher total IV is generally better, especially high Attack. If you have two of the same species with similar levels and moves, choose the one with stronger overall IVs.
For Great League and Ultra League
Meta PvP builds often prefer lower Attack and higher Defense/HP to fit more levels under CP caps (1500 and 2500). A 98% overall IV isn't always the best PvP pick.
Common trainer mistakes
- Powering up only based on IV% and ignoring movesets
- Transferring low-attack PvP gems because total IV looks low
- Ignoring stardust cost and candy budget
- Forgetting that shadows and legacy moves can change value dramatically
Quick FAQ
Is a 100% IV Pokémon always best?
Not always. For Master League and raids, usually yes. For Great/Ultra PvP, stat product builds can outperform perfect IVs.
Can IVs change later?
Usually no, but trading rerolls IVs, and purification sets minimum IV floors for Shadow Pokémon.
Should beginners chase only hundos?
No. Focus first on useful species, strong movesets, and cost-efficient upgrades. IV optimization comes after that.
