Calorie question???

I have a question about calories! I absolutely LOVEEEEEEEEE the french vanilla sugarfree cappuccino's from TOPSTAR. I usually get a 20 ounce, and I'm curious to know how many calories are in them. I've tried looking it up on google but I havn't gotten any results. I usually estimate around 350 calories? I have no problem continuing to estimate, I'm just curious if anyone has any idea if I'm in the ballpark.

Anyone??

i work at a coffee shop. i've never heard of topstar but i assume that is a coffee shop.

skinny: 96 calories and 0 grams fat

2%: 132 calories and 4.8 grams fat

a 20-ounce cappuccino with 2 shots of espresso and 1 ounce (4 pumps) flavor contains only 6-ounces of actually milk. the rest is foam.

a shot of espresso has 5 calories. the syrup has none.
so i would estimate it would have the same amount of calories in a cup of milk maybe and then 10 more for the espresso shots.
