Advanced Gen 5 IV Calculator
Enter the known base stats, current level, effort values, nature, and observed stats. The calculator tests every IV from 0 to 31 for each stat.
Example Data Table
This sample shows how a fast special attacker can be entered. Replace the numbers with your own known stats.
| Setting | Example Value | Meaning |
|---|---|---|
| Level | 50 | Current level at the time stats are viewed. |
| Nature | Timid | Boosts Speed and lowers Attack. |
| Speed Base / EV / Observed | 90 / 252 / 156 | Used to estimate the Speed IV range. |
| Special Attack Base / EV / Observed | 50 / 4 / 70 | Used to estimate Special Attack IV values. |
| Hidden Power | Calculated from possible IV combinations | Gen 5 type and power depend on IV bit patterns. |
Formula Used
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)
Reverse IV Method
The calculator tests IV values from 0 through 31, then keeps every value that produces the observed stat.
A boosted nature uses 1.1. A lowered nature uses 0.9. A neutral nature uses 1.0. HP does not use a nature multiplier.
How To Use This Calculator
- Enter the current level.
- Select the correct nature.
- Enter each base stat.
- Enter known EV values for each stat.
- Enter the observed in-game stat values.
- Press the calculate button.
- Review possible IV ranges above the form.
- Download the result as CSV or PDF if needed.
Use rare candy, level changes, or exact EV tracking for tighter results. Low level monsters usually produce wider IV ranges.
Gen 5 IV Analysis Guide
Why IVs Matter
Individual values shape the final strength of every stat. In Gen Five, each stat can hold an IV from zero to thirty one. A higher value usually means a stronger final stat. The effect becomes easier to see at higher levels. Competitive players use IV checks to compare possible builds. Breeders use them to judge offspring quality. Casual players use them to understand hidden potential.
Why Ranges Appear
One observed stat does not always reveal one IV. The game rounds numbers during stat calculation. Several IV values can create the same visible stat. This is common at low levels. It is also common when EVs are unknown. A range is not an error. It shows every IV that still fits the formula.
Nature And EV Accuracy
Nature is very important for five non HP stats. A boosted stat is multiplied by 1.1. A lowered stat is multiplied by 0.9. A neutral stat keeps its normal value. Wrong nature selection can make results impossible. EVs also change the answer. Four EV points usually add one formula point before level scaling. Accurate EV records give much cleaner results.
Hidden Power Review
Gen Five Hidden Power depends on IV patterns. The type uses the lowest bit of each IV. The power uses the second lowest bit. Because ranges may include many IV values, several types can remain possible. The calculator lists possible types when the search is practical. It also shows a representative result from midpoint IVs. Use this as a planning guide.
Getting Better Results
Check stats after leveling up. Confirm EVs before entering numbers. Avoid using stats changed by battle moves. Use the actual base stats for the correct form. Recalculate after training changes. Compare exact rows first. Exact rows give the strongest evidence. Wide rows need more data.
FAQs
What does this IV calculator do?
It estimates possible Gen 5 IV values from level, base stats, EVs, nature, and observed stats. It checks every IV from 0 to 31.
Why do I get an IV range?
Game formulas use rounding. At some levels, several IV values create the same visible stat. Higher levels and accurate EVs reduce the range.
Why does a stat show impossible?
The entered stat cannot be produced by the selected level, base stat, EV, and nature. Check the observed stat and nature first.
Do HP stats use nature?
No. HP ignores nature modifiers. Attack, Defense, Special Attack, Special Defense, and Speed can be boosted or lowered by nature.
Does this support Hidden Power?
Yes. It estimates possible Hidden Power types and power when the IV combination count is manageable. It also shows a representative midpoint result.
Should EVs be exact?
Exact EVs give better IV estimates. Unknown or wrong EVs can widen ranges or create impossible results for otherwise valid stats.
Can this calculate all six stats?
Yes. The calculator handles HP, Attack, Defense, Special Attack, Special Defense, and Speed in one submission.
Why use a chart?
The chart compares minimum and maximum IV values quickly. It helps you see exact, tight, and wide stat ranges at a glance.
