How much data does Minecraft multiplayer take up?

Okay so i'm going to my dads this weekend and i just got my laptop back and i was wonder how much date minecraft multiplayer takes up. I'm on a server that has an average of 300-400 users and i have a 4GB data cap. We plan on getting unlimited soon but for now this it. I'm using a verizon hotspot and last time i was there i played clash of calns and that took up a total of 2 MB by the time i was done
