Chocolate Coating?

Hi, does anyone know many calories chocolate coating adds to an ice cream bar? (about the size of a magnum or so)

I'm guessing it can't be much but if you eat a few everyday it could add up in a few months? 

My guess is that it'd be at least 100 calories for just the chocolate since it IS chocolate.. but it could vary depending on the type of magnum! :) Dark chocolate less, almond more and so on.

ahhhh no I ate like six today alone :( alright it's an expensive lesson i guess!

thanks!
