What this Pokémon GO IV calculator does

In Pokémon GO, each Pokémon has three hidden Individual Values (IVs): Attack, Defense, and Stamina. Each stat ranges from 0 to 15. This calculator converts those three numbers into a total score out of 45, a percentage, and a star-style appraisal tier so you can quickly decide whether to power up, evolve, trade, or transfer.

If you already know your stat bars from in-game appraisal, this tool gives you the IV result instantly—no spreadsheet required.

How IVs are calculated

The formula is simple:

• Total IV points = Attack + Defense + Stamina
• IV Percentage = (Total IV / 45) × 100

Example: If your Pokémon is 15/14/13, total IV is 42. That means 42/45 = 93.33% IV.

Star tiers used by the calculator

• 4★: 45/45 (perfect IV, often called a hundo)
• 3★: 37–44 total IV
• 2★: 30–36 total IV
• 1★: 23–29 total IV
• 0★: 0–22 total IV

Should you keep high IV Pokémon?

Usually yes—but your decision depends on your goal:

• Raids and Gyms: high overall IV (especially high Attack) is generally preferred.
• Great League / Ultra League PvP: lower Attack with high Defense/Stamina is often better because of CP caps.
• Master League PvP: very high IV, ideally near perfect, is usually best.

Quick practical rules

• Keep all 4★ Pokémon.
• Keep strong raid attackers with high Attack IV and useful typing.
• For Great/Ultra League, check PvP rank before transferring low-Attack spreads.
• Don’t power up everything—save Stardust for relevant meta Pokémon.

Why IVs are important (but not everything)

IVs matter, but they are only one part of performance. Species base stats, move set, level, shadow bonus, weather boost, and team composition all impact battle outcomes. A top-tier species with average IV often outperforms a weak species with perfect IVs.

Use IV data for optimization, not obsession. Build around useful Pokémon first, then refine with better IV versions over time.

Common mistakes trainers make

• Transferring low-star Pokémon that are actually excellent for CP-capped PvP leagues.
• Ignoring move quality and only chasing IV numbers.
• Spending Stardust on non-meta Pokémon with good IVs but poor battle value.
• Assuming 100% IV is mandatory for all game content.

Frequently asked questions

Is 100% IV required for raids?

No. It helps, but it is not required. Team quality, counters, and proper move sets have a larger effect in many situations.

What is a hundo?

A hundo is a perfect 15/15/15 Pokémon with 45 total IV points (100%).

Can a low-IV Pokémon still be useful?

Yes. Many low-Attack, high-bulk combinations perform very well in Great League and Ultra League under CP limits.

Final thoughts

This Pokémon GO Pokémon IV calculator is designed for speed and clarity. Enter your three IV values, get your exact score, and make a smart keep/power-up decision in seconds. Use IVs as a decision tool—but always combine them with move quality, league goals, and actual battle usefulness.
