Type Calculation Formula
Generation III+ (Current Formula):
Type Number = ⌊(a + 2b + 4c + 8d + 16e + 32f) × 15 / 63⌋
- a = HP IV is odd ? 1 : 0
- b = Attack IV is odd ? 1 : 0
- c = Defense IV is odd ? 1 : 0
- d = Speed IV is odd ? 1 : 0
- e = Special Attack IV is odd ? 1 : 0
- f = Special Defense IV is odd ? 1 : 0
The result (0-63) corresponds to a specific type according to the type table.
Power Calculation (Gen III-V):
Power = ⌊(u + 2v + 4w + 8x + 16y + 32z) × 40 / 63⌋ + 30
- u-z are based on whether each IV divided by 4 has remainder 2 or 3
- Power ranges from 30 to 70
Generation VI+ (Simplified):
Hidden Power always has 60 base power, but the type still varies based on IVs.

If You've Ever Wasted Hours Hunting for the Perfect Hidden Power Type, This Calculator Changes Everything
Figuring out Hidden Power type in Pokémon is one of those tasks that sounds simple on paper but turns into a spreadsheet nightmare in practice. You've got a competitive team in mind, you need HP Ice to nail that Garchomp, but your bred Pokémon keeps ending up with HP Dark. Or you're not even sure what IVs to aim for, and every guide online throws formulas at you without showing the result in real time. That's exactly where the Hidden Power Calculator at heycalc.org steps in — a free, browser-based tool that instantly converts any set of Individual Values (HP, Attack, Defense, Special Attack, Special Defense, Speed) into the exact Hidden Power type, base power, and a color-coded type effectiveness chart. It supports every generation from II to IX, so whether you're playing HeartGold or Scarlet, the calculation is correct for your game.
Why This Tool Exists (and Why You'll Actually Use It)
Hidden Power isn't just a weird move with a variable type — it's a cornerstone of competitive team building. The right Hidden Power can turn a coverage gap into a win condition. But the underlying math is fussy. The type depends on whether each IV is odd or even (and for Generations III–V, the power varies too), and there's no in-game display that tells you what you're getting until you've committed to the Pokémon.
Traditional approaches involve either memorising a formula, clicking through clunky Java applets from 2008, or cross-referencing printed IV charts. None of those are fun when you're on your eighth Egg hatch at 2 AM.
The heycalc version feels like a breath of fresh air because it's designed around what you actually need to know: you punch in six numbers (or load a perfect IV preset), pick your game generation, and the result appears instantly. No ads interrupting the flow, no login required, no waiting for a server response.
How to Use the Hidden Power Calculator Like a Pro
The interface is split into three tabs: IV Calculator, Perfect IV Presets, and Type Guide. Most of the time you'll live in the first tab, but the other two are surprisingly useful once you dig into team optimisation.
Entering IVs and Choosing a Generation
Start by entering the IVs of your Pokémon — each stat accepts values from 0 to 31. If you don't know your Pokémon's exact IVs (maybe you haven't levelled it to 50 yet), you can still use approximate values; the calculator will show you the type and power for that specific combination.
Then select the generation:
- Gen VI+ (fixed power 60) covers all modern games, from X/Y through Scarlet/Violet.
- Gen III–V (variable power 30–70) includes the older handheld titles where base power actually matters.
- Gen II uses the original formula with power ranging from 31 to 70.
After clicking Calculate Hidden Power, you'll see a clean results card showing the type, base power, category (physical/special), and the sum of your IVs. Below that, a doughnut chart visualises the move's effectiveness against all 18 types — super effective, neutral, resisted, or immune. This is gold when you're trying to decide whether HP Fire is worth it over a different coverage move.
The "Perfect IV Presets" Tab: No Math Required
One of the most thoughtful features is the Perfect IV Presets table. It lists every possible Hidden Power type with the IV combination that yields maximum power (70 in Gen III–V, or the fixed 60 in Gen VI+). You click a row, and those IVs are automatically filled into the calculator.
For example, if you need Hidden Power Ice, the preset might show 30/30/30/31/30/31 (or similar, depending on generation). You can load it and immediately see the type confirmation. This saves an enormous amount of back‑and‑forth when you're breeding or using Bottle Caps.
Competitive Battling Tips Embedded Right There
The same tab includes a short list of competitive battling tips that reference real Pokémon and meta scenarios:
- HP Fire for Ferrothorn and Scizor coverage
- HP Ice for Dragon‑types like Garchomp and Dragonite
- HP Ground for Electric‑types hitting opposing Electric‑types
- HP Fighting for Normal‑types like Snorlax and Blissey
- HP Grass for Water‑types dealing with Swampert and Gastrodon
These tips make the tool feel like it was built by someone who actually plays VGC or Smogon, not just a generic calculator generator.
Is This Hidden Power Calculator Safe and Private? (Yes—Here's Why)
A lot of online tools ask you to upload files or register an email, which raises a red flag for anyone handling team data from official games. The Hidden Power Calculator runs entirely in your browser — no data is sent to any server. The JavaScript processes your IV inputs locally, and the results are displayed without any network call.
This means you can use it while drafting a competitive team on your phone without worrying about someone scraping your Pokémon data. It's also completely free, with no hidden paywalls or premium tiers. The lightweight code loads quickly even on slower connections, and the interface resizes cleanly for mobile screens.
People Also Ask: Common Questions About Hidden Power and This Calculator
How do I get Hidden Power Fire on a specific Pokémon?
Hidden Power type is determined solely by IVs. To get HP Fire, you need an IV combination where the odd/even pattern (in Gen VI+) matches the Fire table. Use the Perfect IV Presets tab to find the exact spread, then breed or use Hyper Training with Bottle Caps (note: Hyper Training does not change the actual IV value for Hidden Power — only the base stats — so you must have the raw IVs correct. The calculator accounts for this nuance by showing the real IVs needed.)
Does the Hidden Power calculator work for Gen IX (Scarlet/Violet)?
Yes, it supports up to Gen IX. Select "Gen VI+" from the generation dropdown because Scarlet/Violet use the simplified formula where base power is always 60. The type calculation follows the same algorithm as Sun/Moon and Sword/Shield.
What Hidden Power type is best for competitive battling?
There's no single best type — it depends on your team's coverage needs. Hidden Power Ice is extremely common for hitting Dragon and Ground types. Hidden Power Fire is essential for Ferrothorn and Scizor. Hidden Power Ground helps Electric‑types break past other Electric‑types. The calculator's Competitive Battling Tips section gives context for each popular type.
Can I use this calculator on my phone?
Absolutely. The layout is responsive, and all input fields are touch‑friendly. On a small screen, the IV entry grid stacks vertically, and the results card remains easily readable. There's no app to download — just open heycalc.org in your mobile browser.
Does this calculator show Hidden Power base power correctly for older generations?
Yes. When you select Gen III–V, the calculator computes the true base power (ranging from 30 to 70) using the quarter‑remainder method. It also displays the IV sum, which correlates with power — higher sums generally yield higher power. For Gen II, it uses the earlier formula with a different power range.
The Hidden Power Type Guide: Understanding the Formula (Without the Headache)
If you're curious about the inner workings, the Type Guide tab explains the calculation clearly:
Generation III+ (current formula):
The type number is derived from six binary values (1 if the IV is odd, 0 if even) for each stat in this order: HP, Attack, Defense, Speed, Special Attack, Special Defense. The formula is:
Type Number = floor((a + 2b + 4c + 8d + 16e + 32f) × 15 / 63)
That number (0–63) maps to one of the 17 types (excluding Normal, though Fairy is included in modern gens). The guide also shows a polar area chart that visualises the distribution of types across all possible IV combinations — handy if you want to know how rare a certain Hidden Power type is.
Power calculation (Gen III–V):
Instead of odd/even, it uses whether the IV modulo 4 is 2 or 3. The formula is similar but with a different scaling factor, and the final power is clamped between 30 and 70.
Final Thoughts: Why This Calculator Belongs in Every Trainer's Toolbox
After spending a few hours building a team for an upcoming tournament, I can't imagine going back to manual IV charts or outdated online calculators. The Hidden Power Calculator at heycalc.org does one thing and does it well — it eliminates the guesswork from what is arguably the most fiddly mechanic in competitive Pokémon.
It's fast, free, privacy‑respecting, and it works on any device. Whether you're a VGC grinder, a casual breeder, or someone who just wants to understand how the move works under the hood, this tool gives you exactly what you need without asking for anything in return. Load up a few presets, see which types fit your team, and get back to battling with confidence.
Frequently Asked Questions about Hidden Power Calculator
How do I sanity-check the hidden power result?
Rerun the calculator with a known example and compare it against the figure you expect; then swap back to your own numbers.
Which hidden power inputs change the outcome most?
Adjust one field at a time. The figure that shifts the result hardest is the assumption worth double-checking before you rely on it.
How accurate is the Hidden Power Calculator for different game generations?
The calculator uses the exact formulas from Bulbapedia and verified research across each generation. For Gen II, it applies the original algorithm where power depends on a different IV calculation. For Gen VI and later, it correctly forces base power to 60 while still computing type from IV odd/even parity. Test it against a known Pokémon, and you'll see it matches in‑game results.
Do I need to create an account or pay to use the Hidden Power Calculator?
No account, no payment, no subscription. The tool is completely free and does not store any information. All processing happens in your browser's JavaScript engine; nothing is saved on the server.
Can I see the IV combination needed for a specific Hidden Power type without manual trial and error?
Yes. Open the Perfect IV Presets tab, and you'll find a complete table with every Hidden Power type and its ideal IV spread. Click the "Load" button next to any row to instantly populate the calculator inputs. You can also tweak individual IVs afterward to see how changes affect the result.
What if the Hidden Power type I want is not listed in the presets?
All 17 possible types (excluding Normal) are covered. If you don't see a type, it's because Hidden Power can never be that type under the current formulas (it cannot be Normal or Fairy? Actually Fairy is possible in Gen VI+ — the presets include Fairy. So all types are there). Scroll through the table; if you still don't see it, double‑check your generation selection — in Gen II, the type table is slightly different.
