Introduction
Every Pokémon has hidden stats called Individual Values (IVs). These secret numbers decide how strong your Pokémon really is. Two Pokémon of the same species can have very different power levels because of their IVs. Knowing your Pokémon's IVs helps you pick the best ones for battles, raids, and PVP.
This Pokémon IV Calculator works for both Pokémon GO and main series games like Scarlet, Violet, Sword, and Shield. In the Pokémon GO tab, enter your Pokémon's CP, HP, Stardust cost, and appraisal details. The tool then finds every possible IV combination that matches your inputs. You can even add power-up data to narrow results down further. In the Main Series tab, enter your Pokémon's level, nature, observed stats, and EVs to calculate each stat's IV range.
This calculator gives you the exact numbers you need to make smart choices fast when you build a Great League PVP team in Pokémon GO or breed competitive Pokémon in the main games.
How to Use Our Pokémon IV Calculator
Enter your Pokémon's stats from the game, and this calculator will show you its hidden Individual Values (IVs). IVs are secret numbers that make each Pokémon stronger or weaker. Pick the Pokémon GO tab or the Main Series tab depending on which game you play.
Pokémon GO Mode
Pokémon Species: Type your Pokémon's name into the search box. Pick the correct one from the list that appears.
CP (Combat Power): Enter the CP number shown on your Pokémon's screen in Pokémon GO.
HP (Hit Points): Enter the HP number shown on your Pokémon's screen. You can find this below the health bar.
Stardust Cost: Choose the amount of Stardust needed to power up your Pokémon. This helps the calculator figure out your Pokémon's level. If you don't know it, leave it set to "Unknown."
Just Caught / Not Powered Up: Check this box if you have not powered up this Pokémon yet. This cuts the possible results in half and gives you a more accurate answer.
Overall Star Rating: Open the appraisal screen in Pokémon GO and pick the star rating your team leader gives. It ranges from 0 stars to Wonder (a perfect 100%).
Best Stat(s): Check the stats that your team leader says are the best. If the leader highlights more than one stat as equal, check all of them.
Best Stat Value Range: Pick the bar range your team leader shows for the best stat. A full orange bar means 15 (Max).
Power-Up Narrowing: Click "Add Power-Up Data" if you want even fewer results. Power up your Pokémon once, then enter the new CP, HP, and Stardust cost. You can add more than one power-up to narrow it down further.
Calculate IVs: Press the Calculate button to see all possible IV combinations. The results table shows each possible Attack, Defense, and Stamina IV along with the IV percentage and quality rating. A bar chart below shows how many results fall into Perfect, Great, and Good categories.
Main Series Mode (Gen 3–9)
Pokémon Species: Type your Pokémon's name and pick it from the list. This loads the correct base stats.
Level: Enter your Pokémon's current level, from 1 to 100. You can find this on the summary screen in your game.
Nature: Choose your Pokémon's nature from the dropdown. Natures boost one stat by 10% and lower another by 10%, so picking the right one matters for an accurate result.
Mechanics: Leave this set to "Gen 3–9" for all modern Pokémon games. IVs range from 0 to 31 in these games.
Observed Stats: Enter each stat number exactly as it appears on your Pokémon's summary screen. Fill in HP, Attack, Defense, Sp. Atk, Sp. Def, and Speed.
EVs (Effort Values): Enter the EVs your Pokémon has earned for each stat, from 0 to 252. If you haven't trained it at all, leave every EV at 0. Wrong EV numbers will give wrong IV results.
Calculate IVs: Press the Calculate button to see the possible IV range for each stat. The results table shows every matching IV, a best guess, and the total IV percentage. A bar chart below displays the best guess IV for each stat so you can see your Pokémon's strengths at a glance.
What Are Pokémon IVs?
IVs stand for Individual Values. They are hidden numbers that every Pokémon has. These numbers affect how strong your Pokémon's stats are. Two Pokémon of the same species and level can have different stats because of their IVs. Think of IVs like a Pokémon's natural talent: some are just born stronger than others.
IVs in Pokémon GO
In Pokémon GO, each Pokémon has three IV stats: Attack, Defense, and Stamina (HP). Each one ranges from 0 to 15. A perfect Pokémon has 15 in all three, giving it a total IV percentage of 100%. The in-game appraisal feature gives you clues about your Pokémon's IVs using star ratings and bar graphs. IVs matter a lot in PVP battles, raids, and Gym fights. For PVP leagues like Great League and Ultra League, the best IVs are often not 15/15/15. Instead, you usually want low Attack and high Defense and Stamina to fit under the CP cap. Once you know your IVs, our Pokémon Damage Calculator shows how those stats translate into actual battle damage.
IVs in Main Series Games (Gen 3–9)
In the main Pokémon games like Scarlet, Violet, Sword, and Shield, IVs range from 0 to 31 for six stats: HP, Attack, Defense, Special Attack, Special Defense, and Speed. Higher IVs mean higher stats. Your Pokémon's nature also changes stats by boosting one by 10% and lowering another by 10%. For competitive battling, trainers breed or use items like Bottle Caps to get the best IVs possible. A perfect 31 IV in every stat gives you the strongest version of that Pokémon.
Why IVs Matter for PVP
Knowing your Pokémon's IVs helps you pick the best ones for battles. In Pokémon GO PVP, even a small IV difference can decide who wins a close fight. In the main series, competitive players always aim for ideal IVs to get every edge they can. This calculator takes the information you can see, like CP, HP, level, nature, and stats, and works backward to figure out the hidden IV numbers.
