Advanced IV Entry Form
Example Data Table
This sample uses a Level 50 Jolly Dragapult with common training values.
| Stat | Base | EV | Shown Stat | Expected IV | Note |
|---|---|---|---|---|---|
| HP | 88 | 0 | 163 | 31 | HP ignores nature. |
| Attack | 120 | 252 | 172 | 31 | Jolly is neutral here. |
| Defense | 75 | 0 | 95 | 31 | No nature change. |
| Sp. Atk | 100 | 0 | 108 | 31 | Jolly lowers this stat. |
| Sp. Def | 75 | 4 | 96 | 31 | Four EVs add one formula point. |
| Speed | 142 | 252 | 213 | 31 | Jolly boosts this stat. |
Formula Used
The calculator tests every IV from 0 through 31. It returns every IV that recreates the stat you entered.
Nature equals 1.1 for a boosted stat, 0.9 for a lowered stat, and 1.0 for a neutral stat. Shedinja style base HP of 1 is handled as fixed HP of 1.

About IV Planning in Sword and Shield
Why IVs Matter
Individual values shape the final stats of every Pokémon. They are hidden numbers, yet they affect battles every turn. A higher IV usually means a stronger final stat. The difference can decide a knockout, a speed tie, or a safe defensive benchmark. This calculator helps you estimate those hidden values from visible data.
Level and EV Accuracy
Level changes the accuracy of an IV reading. At low levels, many IVs can create the same shown stat. At level 50, ranges are usually narrower. At level 100, single IV values are often easier to confirm. EVs must also be correct. Even one missed training point can change the result.
Nature Effects
Nature is important because it changes non-HP stats after the base formula. A boosted stat is multiplied by 1.1. A lowered stat is multiplied by 0.9. Neutral natures use 1.0. HP never receives a nature boost or penalty. Choose the right nature before judging the result.
Competitive Use
Perfect IVs are not always best. Physical attackers may want low Special Attack ignored. Trick Room teams often want zero Speed. Special attackers may prefer low Attack to reduce confusion and Foul Play damage. The calculator shows ranges, so you can decide whether a Pokémon fits a team plan.
Exporting Results
Use the CSV export for spreadsheets and team databases. Use the PDF export for quick reports. Both include base stats, EVs, visible stats, nature modifiers, and possible IV ranges. Keep records when breeding, trading, or comparing multiple builds. Clear notes prevent mistakes during training.
Checking Data Carefully
Always confirm the form before trusting a result. Make sure the Pokémon is not using a different form. Check whether vitamins, feathers, jobs, or battles changed EVs. Remove items, battle boosts, and temporary effects from your thinking. The summary should match the normal stat screen, not a boosted battle value.
Using Ranges Well
A range is still useful. If Speed shows 30 to 31, the Pokémon is almost ideal. If Attack shows 0 to 3, it may fit special sets. Use the judge label as a quick guide, then read the exact range for serious planning.
Frequently Asked Questions
What is an IV?
An IV is a hidden value from 0 to 31. Each main stat has its own IV. Higher values usually create stronger final stats.
Why do I get an IV range?
Several IVs can produce the same visible stat, especially below level 100. The calculator lists every IV that matches your entered data.
Does nature affect HP?
No. Nature affects Attack, Defense, Special Attack, Special Defense, or Speed. HP always uses the HP formula without a nature multiplier.
Why is no exact IV found?
Your base stat, EV, nature, level, form, or visible stat may be wrong. Check each value and calculate again.
Can I use this for level 50 battles?
Yes. Level 50 is common for competitive play. Some stats may still show ranges because visible numbers are rounded down.
Do EVs over 252 work?
No legal Sword and Shield stat can use more than 252 EVs. The form limits each EV field to that maximum.
What is a perfect IV spread?
A common perfect spread is 31 in all six stats. Some strategies prefer 0 Attack or 0 Speed instead.
Can I export my result?
Yes. Use the CSV button for spreadsheets. Use the PDF button for a simple printable result summary.
