What this IVs Pokémon GO calculator does

This tool calculates your Pokémon's total IV score and IV percentage using the three hidden stats in Pokémon GO: Attack, Defense, and Stamina. Each stat ranges from 0 to 15, so a perfect Pokémon has 15/15/15 for a total of 45/45 (100% IV).

Trainers use IV calculators to decide which Pokémon are worth powering up, evolving, or keeping for raids, gyms, and PvP leagues. A quick calculation can save Stardust, Candy, and time.

How IV percentage is calculated

The formula is straightforward:

• Total IV = Attack + Defense + Stamina
• IV % = (Total IV ÷ 45) × 100

For example, a Pokémon with 13 Attack, 14 Defense, and 15 Stamina has: 42 total IV, which equals 93.33%.

Star rating tiers (appraisal equivalent)

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

How to use the calculator correctly

1. Open your Pokémon in Pokémon GO.
2. Tap Appraise and note the three bar values (or exact IV numbers if you use overlays/tools).
3. Enter Attack, Defense, and Stamina IV values in the fields above.
4. Click Calculate IV %.
5. Review total IV, percentage, star tier, and gameplay note.

Are higher IVs always better?

Usually, yes—but not always. The best IV spread depends on your goal:

For raids and gym offense (PvE)

Higher IVs are generally best, especially high Attack IV. If you're deciding between two Pokémon of similar level and species, the one with better IVs is often the stronger long-term investment.

For Great League and Ultra League (PvP)

High IV percentage can be misleading in CP-capped leagues. Many top PvP builds prefer lower Attack and higher Defense/Stamina to maximize bulk under the CP cap. So a 0/15/15-style spread can outperform a 15/15/15 in certain matchups.

Practical IV hunting tips

• Use weather boosts and event spawns to increase your chance of strong catches.
• Trade with friends for rerolls—Lucky trades are especially valuable.
• Prioritize species usefulness before chasing perfect IVs.
• Keep an eye on move sets; IVs matter, but moves matter too.
• For PvP, check rank tools in addition to raw IV percentage.

Common mistakes trainers make

• Powering up low-level Pokémon too early without checking IVs.
• Ignoring good PvP spreads because they are not high IV %.
• Transferring "decent" Pokémon that may be useful for special cups.
• Assuming IVs alone decide battles—team composition and timing are huge factors.

Frequently asked questions

What is a "hundo" in Pokémon GO?

A "hundo" is a 100% IV Pokémon with 15 Attack, 15 Defense, and 15 Stamina (45/45 total).

Is a 0-star Pokémon always bad?

Not necessarily. Some low-star Pokémon can still be useful in niche PvP formats, and high level can sometimes compensate for lower IVs in casual play.

Should I evolve first or power up first?

Most trainers evolve first, then decide whether to invest Stardust based on final moves, IVs, and intended use case.

Does IV matter more than level?

In the short term, level usually has a bigger impact than a small IV difference. In the long term, high IV plus high level gives best performance.

Bottom line
