pokemon iv calculator

Pokémon IV Calculator (Main Series)

Use this tool to estimate possible Individual Values (IVs) for one stat based on your Pokémon’s observed stat, level, EVs, base stat, and nature.

Stat Type

Base Stat Find this from Pokédex resources for the exact species and form.

Observed In-Game Stat

Level

EVs in This Stat In modern games, max EV per stat is usually 252.

Nature Modifier Used for non-HP stats only.

What this pokemon iv calculator does

A Pokémon’s IV (Individual Value) is a hidden number between 0 and 31 for each stat. Higher IVs mean better raw stat potential. This calculator helps you reverse-engineer likely IV values by plugging in known data from your game.

Instead of guessing whether your Pokémon is “good,” you can estimate how strong that individual stat really is. This is useful for breeding projects, battle team building, raid prep, and deciding if a Pokémon is worth investing mints, bottle caps, or EV training resources.

How to use the calculator

Select whether you are calculating HP or a non-HP stat.
Enter the species’ base stat for that stat.
Enter the stat you currently see in-game.
Enter your Pokémon’s exact level.
Enter EVs in that stat (if unknown, start with 0 and test ranges).
Select nature modifier for non-HP stats.
Click Calculate IV Range.

Formula used in this tool

HP stat formula

HP = floor(((2 × Base + IV + floor(EV / 4)) × Level) / 100) + Level + 10

Non-HP stat formula

Stat = floor((floor(((2 × Base + IV + floor(EV / 4)) × Level) / 100) + 5) × Nature)

The calculator checks all IV values from 0 to 31 and returns every value that reproduces your observed stat exactly. If more than one IV appears, that means your current level/EV setup does not uniquely identify a single IV yet.

Interpreting your results

You may get one IV (exact), or a range of possible values. Early levels often produce wider ranges due to rounding. To narrow results, raise the level and run the calculation again with updated stats.

Single value: You found the exact IV for that stat.
Narrow range (e.g., 28–31): Very strong stat, likely battle-viable.
Wide range: Need more data (higher level, confirmed EVs, and correct nature).

Practical optimization tips

1) Confirm nature first

Using the wrong nature modifier (1.1, 1.0, or 0.9) can shift all outputs. Always verify nature before you calculate.

2) Track EV training carefully

If EVs are uncertain, calculate multiple scenarios (0, 4, 252, etc.). EV uncertainty is one of the biggest causes of confusing IV ranges.

3) Re-check after leveling

Recalculating at a higher level often collapses a wide range into a single precise IV value.

FAQ

Does this work for Pokémon GO?

No. This calculator is designed for the main-series stat formulas. Pokémon GO uses a different appraisal and stat system.

What is a “perfect IV”?

A perfect IV is 31 in a stat. Competitive players often target 31 in key stats, though some niche builds intentionally run low values (for example, low Speed in Trick Room teams).

Why do I get no matching IVs?

Usually one input is incorrect: base stat, level, EV count, nature, or observed stat. Double-check each value and try again.

Final thoughts

A good pokemon iv calculator saves time, prevents wasted training resources, and helps you make smarter roster decisions. Use this tool whenever you catch, hatch, or breed a promising Pokémon and want to know whether it deserves long-term investment.
