It depends on the size of your cup but I'm using a 12oz cup, and I noticed that using just the half Carafe level, I can fill 2 cups with some left over (i'm guessing around ~2-3oz) but it's not enough for another cup for sure. And i think that makes sense since it's suppose to be a 24 oz for a half carafe but in my case, I don't usually fill my cup to the rim anyway since I add liquid coffee creamer for added flavor so I maybe using only max of 10 oz per cup. So for a full Carafe, I would say depending on whether you fill the cup to the rim or not, more or less, it's good for 4 cups of coffee.
