It just says the same thing regardless of what I enter:
1 million annual:
> If you got to keep your fair share of the profit Amazon.com reported, $77.7B, your salary would be $1.049.283. You helped Amazon.com make enough to pay you $49.283 more.
3 million annual:
> If you got to keep your fair share of the profit Amazon.com reported, $77.7B, your salary would be $3.049.283. You helped Amazon.com make enough to pay you $49.283 more.
1 dollar per year:

Good catch, thanks! That was a locale bug. If your browser is set to a European locale, the number formatting was using periods instead of commas. Just pushed a fix, should be live in a minute or two.
You're right that the per-employee share is the same regardless of salary. That's the point: it shows what the company made per head, and then what your salary would look like with that added on top. The salary input just personalizes it.
