Example Data Table
| Example | Level | Base Stat | Observed Stat | EV | Nature | Expected Use |
|---|---|---|---|---|---|---|
| Fresh hatch HP | 1 | 55 | 12 | 0 | 1.00 | Early breeding check |
| Ranked attacker | 50 | 116 | 168 | 252 | 1.10 | Battle ready review |
| Speed control | 50 | 30 | 31 | 0 | 0.90 | Trick Room check |
| Special wall | 100 | 110 | 256 | 252 | 1.10 | Defensive spread review |
Formula Used
The calculator tests every possible IV from 0 to 31. This method handles in-game rounding better than a direct reverse formula.
HP Formula
HP = floor(((2 × Base + IV + floor(EV ÷ 4)) × Level) ÷ 100) + Level + 10
Other Stat Formula
Stat = floor((floor(((2 × Base + IV + floor(EV ÷ 4)) × Level) ÷ 100) + 5) × Nature)
Nature is 1.10 for a raised stat, 0.90 for a lowered stat, and 1.00 for a neutral stat.
How To Use This Calculator
- Enter the Pokémon level.
- Choose a preset or type each base stat manually.
- Enter the observed in-game stat values.
- Add known EV values for each stat.
- Select nature modifiers for non-HP stats.
- Press the calculate button.
- Review exact IV ranges and rating labels.
- Download the result as CSV or PDF when needed.
Why This IV Tool Matters
Individual values shape the hidden potential behind every stat. A Pokémon with strong IVs can reach better final numbers at the same level. This matters in raids, ranked battles, breeding chains, and careful training plans. Sword and Shield players often see only broad judge phrases. This calculator turns visible stats into clearer IV ranges.
Built For Practical Checks
The tool uses level, base stats, effort values, nature, and observed stats. It then tests every possible IV from 0 to 31. This avoids weak reverse guesses. It also respects rounding inside the game formula. You can enter a fresh hatch, a trained partner, or a raid catch. EV fields let you test trained builds instead of assuming zero investment.
Reading The Results
Each row shows the matching IV values for one stat. A single value means the inputs identify that stat exactly. A range means several IVs can produce the same visible stat. This is common at low levels. Higher levels usually narrow the range. The overall score uses the midpoint of each matching range. It is a guide, not an official rating.
Better Breeding Decisions
Breeding is easier when weak stats are visible early. You can compare parents, mark perfect stats, and decide which offspring deserve bottle caps later. A speed value of zero can also be useful for Trick Room teams. That is why the calculator labels low and perfect values clearly.
Export And Review
Use the CSV button to save rows for spreadsheets. Use the PDF button for a quick report. Both downloads help when comparing several Pokémon. Keep notes beside nature, EV spread, and held items. Small details can change the visible stat. Accurate entries give the best results.
When checking several candidates, keep names consistent. Record ability, role, and notes too. A clear log prevents confusion. It also helps you spot spreads worth training before spending rare items later with confidence.
Tips For Accuracy
Check the current level first. Enter the correct nature modifier for each non-HP stat. Use one if the nature does not affect that stat. Add all known EVs. For untrained Pokémon, keep EVs at zero. If no exact match appears, review every input before judging the result.
FAQs
What is an IV?
An IV is a hidden value from 0 to 31. It affects how high a stat can become. Higher IVs usually produce better final stats.
Why does the result show a range?
A range appears when several IV values create the same visible stat. This often happens at low levels because rounding hides small differences.
Does HP use nature?
No. HP is not raised or lowered by nature. The calculator ignores nature for HP and applies it only to other stats.
Should EVs be zero for new Pokémon?
Usually yes. Freshly hatched or newly caught Pokémon often have zero EVs. Trained Pokémon need the correct EV values entered.
Why is there no exact match?
An input may be wrong. Check the level, base stat, observed stat, EV value, and nature modifier. One wrong field can break the match.
Can this help breeding?
Yes. It helps you spot strong parents and useful offspring. It also helps identify perfect, weak, or special speed IV spreads.
What does Best mean?
Best means the stat has a 31 IV. That is the highest natural IV value used by the calculator.
Can I export many checks?
Yes. Run the calculator, then use the CSV or PDF button. Save separate reports for each Pokémon you compare.
