Check out the calculator at http://www.ark-survival.net/en/taming-calculator/

shows you what you need to tame and how long.

I found a really good taming calculator too, I use this one all the time.

I highly recommend Dodorex app (Android), it means you won't have to switch screens to use, and will also give timer for starve taming, egg hatch stats etc
