Remote Desktop Connection Data Usage

Does anyone know how much data it uses when I use Windows Remote Desktop Connection for an hour for normal office uses?

I'm asking because I need to connect to a computer remotely and I have to pay for the amount of data I use. Thanks

"Hourly bandwidth consumption at rates like these can vary from ~12M to 3.4G+. Unless you are watching video over RDP, the higher end of the ladder is highly unlikely. For normal activity at 1024x768 resolution with standard settings I'd estimate about ~25M per hour." (c) John T
