How IVs Work in Pokémon GO

In Pokémon GO, every Pokémon has three hidden individual values (IVs): Attack, Defense, and Stamina. Each stat ranges from 0 to 15, giving a total possible IV score of 45. A perfect Pokémon, often called a hundo, has 15/15/15.

This IV calculator helps you quickly convert those three numbers into a percentage so you can compare catches and decide which Pokémon are worth evolving, powering up, or saving for trade.

What This Calculator Tells You

• Total IV percentage (for example, 93.33%)
• Star tier equivalent (0★ to 4★)
• Stat-by-stat bars for attack, defense, and stamina
• Quick guidance for raid/Master League style vs bulk PvP-style spreads

IV Star Tier Reference

Pokémon GO Appraisal Brackets

• 4★: 45/45 total (100%)
• 3★: 37-44 total
• 2★: 30-36 total
• 1★: 23-29 total
• 0★: 0-22 total

Remember: higher IVs are generally better, but they are not the only thing that matters. Species base stats, moveset, level, and league CP caps often matter more than raw IV percentage.

Should You Always Keep the Highest IV?

For Raids and Gyms

Usually yes. High attack IV and high overall IV are strong for raid damage and for max-level builds. If you're deciding between two similar Pokémon for PvE, the higher IV one is usually the long-term investment.

For Great League and Ultra League PvP

Not always. Because of CP caps, many PvP builds prefer lower attack and higher defense/stamina. That lets the Pokémon reach a higher level while staying under the cap, often resulting in better bulk.

That's why a spread like 0/15/15 can outperform a 15/15/15 version in some leagues. This calculator gives a quick hint, but true PvP ranking is species-specific.

Practical Tips for Using IV Data

• Tag Pokémon by role: Raid, GL PvP, UL PvP, Trade.
• Do not spend stardust immediately; compare several candidates first.
• Check moveset availability before committing Elite TMs.
• Evaluate shadows separately; they can outperform regular forms in raids despite lower IVs.
• Use IVs as a tie-breaker when species, level, and moves are close.

Common Mistakes Trainers Make

1) Overvaluing IV over Pokémon level

A high-level 89% Pokémon is often more useful right now than a low-level 100% Pokémon, especially if stardust is limited.

2) Ignoring move quality

A strong moveset can create more battle impact than a small IV difference. Always check fast and charged move performance.

3) Transferring low-attack PvP candidates

Many trainers accidentally transfer excellent PvP spreads because the percentage looks low. For capped leagues, lower overall IV can still be ideal.

Quick IV Decision Framework

• If raid focus: prioritize high attack and high total IV.
• If Master League: usually prefer the highest possible IV, ideally 15/15/15.
• If Great/Ultra League: evaluate CP-optimized spreads by species and rank tools.
• If casual play: keep what you enjoy and avoid over-spending resources.

Final Thoughts

A Pokémon GO IV calculator is best used as a fast decision helper, not the only rule. Combine IVs with level, moves, and your gameplay goals. If you raid heavily, high IV attackers pay off over time. If you play PvP, species-specific rank spreads matter more than headline percentage.

Use the calculator above whenever you appraise a catch, and you'll make cleaner, faster team-building decisions without wasting stardust.
