What is the formula to calculate IVs and EVs?

Nov. 19, 2013

I assume that IV and EV calculation share the same formula.

Also, state each formula from each generation, if they have different formulas per gen.

The formulas for working out your stats are:

So to work out an IV or EV for a stat, it’s a matter of simply reversing the calculation. If you’re not good at algebra it can be a little difficult so here they are. For HP:

For the other stats:

These formulas have been the same since Generation 3, and as far as I know haven’t changed in X/Y. The Nature modifier is 1.1 for positive nature, 1 for neutral, 0.9 for negative nature.

Note: I’m using the normal mathematical “order of operations” to make the formulas clearer, multiplication/division comes first, so for exampleIV + 2Base + EV/4 + 100is the same asIV + (2Base) + (EV/4) + 100.
