Input a pokemon's IVs, current level, and desired level; CP calculator will tell you the resulting CP and HP, and how much stardust and candy you need (and buddy distance and catches to get that much candy).

I like the slide bar tool on this sight. Fast and easy way to start any level and see how much it will cost to go to any other level.
