Pokémon IV Calculator (Serebii-Style Quick Tool)
Enter your Pokémon's level, base stats, observed stats, EVs, and nature effect for each stat. Click Calculate IVs to see possible IV values (0-31).
What is an IV calculator (and why people search “iv calculator serebii”)?
In mainline Pokémon games, IVs (Individual Values) are hidden numbers from 0 to 31 for each stat: HP, Attack, Defense, Special Attack, Special Defense, and Speed. Competitive players use IV calculators to reverse-engineer these values from visible in-game stats.
Many players search for “iv calculator serebii” because Serebii is a trusted Pokémon resource. This page gives you a clean, browser-based calculator with similar practical use: input your known values, then instantly view possible IV ranges.
How this IV calculator works
Stat formulas used
For generations using modern stat formulas, the calculator checks IV values from 0 to 31 and keeps only the values that match your observed stat.
- HP: floor(((2 × Base + IV + floor(EV/4)) × Level) / 100) + Level + 10
- Other stats: floor((floor(((2 × Base + IV + floor(EV/4)) × Level) / 100) + 5) × Nature)
Nature is 1.1 for boosted stats, 0.9 for reduced stats, and 1.0 for neutral.
Why you may see a range instead of one exact IV
At lower levels, multiple IV values can produce the same displayed stat due to rounding. If you level up your Pokémon, or provide exact EV training info, the IV range usually narrows.
Step-by-step usage guide
- Set your Pokémon’s level.
- For each stat row, enter Base Stat and Observed Stat.
- Enter EVs (0-252) for each stat.
- Choose the nature effect for each non-HP stat.
- Click Calculate IVs.
The summary box gives total IV range and a quick quality signal, while each row shows the exact candidates for that specific stat.
Common mistakes that cause “No match”
- Wrong level entered (especially after candy/training changes).
- Forgotten EV investment from battles, vitamins, feathers, or wings.
- Incorrect nature multiplier selected for a stat.
- Using temporary stat stages (battle boosts/drops) instead of raw menu stat values.
Breeding, Hyper Training, and practical IV goals
Breeding targets
For many competitive builds, aiming for 31 IV in key stats (often Speed plus one offense stat) is ideal. Defensive Pokémon may prioritize HP and one or two defenses instead.
When 0 IV is actually good
Some strategies intentionally seek 0 Speed IV (for Trick Room teams) or 0 Attack IV (to reduce Foul Play and confusion self-damage on special attackers).
Hyper Training note
Hyper Training makes stats perform as if IVs are maxed in battle calculations, but it does not always replace naturally perfect IVs for breeding inheritance. Keep that distinction in mind.
Quick FAQ
Does this tool work for all Pokémon?
Yes, as long as you enter the correct base stats, level, EVs, observed stats, and nature effects.
Can this calculator handle unknown EVs?
It assumes you provide EVs. If EVs are unknown, test likely EV spreads and compare resulting ranges.
Is this the official Serebii calculator?
No. This is an independent, Serebii-style educational calculator page replica.
