ChatGPT Team Annual plan add/remove member related question

So, I have paid for two-member team annual plan on the 5th of December. I added the third member on February 27 (now I have 3/2 seats). Imagine, tomorrow (March 3), I will remove this user. Will I be charged for the third user based on the number of days I was in a team or for the whole remaining year in my next invoice?
