Pokemon Rebirth Stat Calculator — Main-Series Reference, Not Official
Editorial contact: Raymond
This tool applies the main-series stat formula to a base stat, IV, EV spread, level and nature. It is a reference calculator, not an official Pokemon Rebirth tool: the experience page does not publish a stat system.
Reference only. If the game shows a different value, the game is right — this tool is not a Rebirth-confirmed formula.
Do not use this as proof of an in-game IV. The experience page does not confirm IVs, EVs or natures. Use the tool to understand the main-series formula, then check the in-game summary for what the build actually displays.
| Stat | Base | IV (0–31) | EV (0–252) | Result at Lv 50 |
|---|---|---|---|---|
| HP | 155 | |||
| Attack | 110+10% | |||
| Defense | 100 | |||
| Sp. Attack | 90−10% | |||
| Sp. Defense | 100 | |||
| Speed | 100 |
The tool applies the main-series formula above and nothing else. It is not a Pokemon Rebirth calculator: the experience page does not publish IV, EV or nature data, and no result here should be treated as an in-game value.
How to use the reference tool
- Set a level. Level 50 is a common midpoint; level 100 is the main-series endgame reference.
- Enter a base stat only if the game or a reference page supplies one.
- Enter an IV and EV spread to see how the main-series formula responds.
- Pick a nature to see the 10% swing in the reference model.
Main-series stat formula (Generations III–IX), cross-checked against Bulbapedia's Stat article. The Pokemon Rebirth experience page does not publish its own formula or stat system, so this calculator is a reference tool only.
What the reference calculator is doing
HP = floor(((2 × base + IV + floor(EV / 4)) × level) / 100) + level + 10
other = (floor(((2 × base + IV + floor(EV / 4)) × level) / 100) + 5) × nature
Nature is 1.1 for the boosted stat, 0.9 for the reduced stat and 1.0 otherwise. This is the main-series formula. It is not confirmed for the Pokemon Rebirth build.
FAQ
FAQ
Is this an official Pokemon Rebirth calculator?
No. It applies the main-series stat formula. The official experience page does not publish IV, EV, nature or stat formulas for this build, so the result is a reference model, not an in-game value.
Where do I find the base stat?
From the in-game summary of the species, if the build shows one. Do not enter a trained stat as if it were a base stat. If the game does not display base stats, the tool cannot reproduce that build.
Why is a 31 IV only a few points better than a 0 IV?
In the main-series formula the IV is scaled by level. At level 100 the difference is about 31 points; at level 50 it is roughly half. This is a property of the reference formula, not a statement about Pokemon Rebirth.
Does the calculator store my inputs?
No. Everything runs in your browser. Nothing you type is sent to a server.
