Calories in cottage cheese?

I am really confused. I make my own cottage cheese at home by boiling 1% milk and adding left over whey/lemon juice to separate the cheese. 2 quarts/2000 gm milk gives me about  1.5 cup/12 oz cheese, and 1500 gm leftover whey. How many calories would the resulting cheese have? I do not add any milk/cream to the separated cheese, but usually leave some whey in to keep it soft.

It'll be pretty close to the standard amount per 100g for 1% fat cottage cheese as listed in the CC database.   Or close enough not to matter.
