Okay, I'm lost...

Heres my Level 1 Mudkip.
HP: 12
ATK: 6
DEF: 6
SP.ATK: 6
SP.DEF: 5
SPEED: 6
Lax Nature.

What would the IV be?
How would I calculate it from a level 1 Pokemon?
I checked the Guide on it and I just dont understand those random formulas.

Try Metalkid's IV Calculator (Look it up on Google, as I'm not sure I can link to it)

But first, have an IV Battle, (set the levels at 100 and write down the stats), then type those into the calculator and see what the outcome, and by the way, Lax isn't a good nature for Swampert, Relaxed is better.

You won't be able to gain accurate IV values at level 1.

You can't determine IV's like that. Use Serebii's 4th-gen IV calculator. Rare Candy the Pokemon to lvl 40ish if you have an AR, so you don't get any EV's mixed in with the stats. Punch in all the stats and you'll see what IV's your Pokemon got. The higher the level on the Pokemon, the more accurate the calculator is. [You won't want to be using a Lax swampert, by the way. =P] Hope this helps.

Okay... I actually get it now.
Thanks.
