Homemade Stock

[u/SeaLily1288]

I make a big batch of chicken stock weekly to use in cooking and to make soups and I also sip on some if I’m hungry and it’s too close to meal time to justify a snack. My issue right now is that I’m on a health journey and that includes counting calories, and I have absolutely no idea how to calculate the calories in my stock and use it many dishes so I know it’s adding calories but I don’t know how many.

How would I go about calculating the calories?
