Pokémon GO IV Calculator
Enter the individual values (IVs) for Attack, Defense, and Stamina. Each stat ranges from 0 to 15.
What Is IV in Pokémon GO?
In Pokémon GO, IV stands for Individual Values. These are hidden stat bonuses assigned to each Pokémon when it is caught, hatched, traded, or encountered through research. There are three IV stats:
- Attack IV
- Defense IV
- Stamina IV
Each value ranges from 0 to 15, so the maximum total is 45. A Pokémon with 15/15/15 is considered a hundo (100% IV) and receives a 4★ in appraisal.
How This IV Calculator Works
This tool uses the standard IV formula used by trainers:
IV % = (Attack + Defense + Stamina) ÷ 45 × 100
After calculating your percentage, the tool also gives you:
- Appraisal star tier (0★ to 4★)
- Quality label (Good, Great, Excellent, etc.)
- Highest stat indicator (or ties)
How to Use the Calculator
Step 1: Check in-game appraisal
Open your Pokémon storage, select a Pokémon, and tap Appraise. If you already know exact values from your scan or overlay app, enter those values directly.
Step 2: Enter Attack, Defense, and Stamina
Type numbers from 0 to 15 in each field. Only whole numbers are valid.
Step 3: Click Calculate
The tool instantly shows total IV points, IV percentage, appraisal tier, and a quick summary so you can decide whether to keep, evolve, or transfer.
Appraisal Tiers at a Glance
- 4★: 45/45 (100%)
- 3★: 37-44 total IV
- 2★: 30-36 total IV
- 1★: 23-29 total IV
- 0★: 0-22 total IV
Do High IV Pokémon Always Win?
Not always. IV matters, but context matters more:
- Raids and Gyms (PvE): Higher IV is generally better, especially high Attack.
- Great/Ultra League PvP: Many top builds prefer lower Attack and higher bulk to stay under CP caps.
- Master League: You usually want the highest IV possible, often 15/15/15.
So a 100% IV Pokémon is amazing, but a lower-IV Pokémon can still be the better battle pick for specific leagues.
When Should You Power Up?
Before spending Stardust and Candy, ask yourself:
- Is this Pokémon useful in current raid or PvP metas?
- Does it have a strong moveset (or Elite TM potential)?
- Is this the best specimen I have for its role?
- Will I regret powering it up before Community Day or special events?
A practical strategy is to keep strong candidates (high IV, useful species, good moves) and delay major investment until you are sure.
Common Trainer Questions
What is a “good” IV in Pokémon GO?
For general play, 82%+ is usually considered good. For serious raid teams, many players target 90%+.
Is a 0/15/15 Pokémon bad?
For raids, usually yes. For some Great League or Ultra League builds, it can be excellent due to better stat product under CP limits.
Should I purify for higher IV?
Purifying raises each IV by +2 (up to 15), but you lose the Shadow attack bonus. Shadow Pokémon can outperform purified ones in many PvE scenarios.
