Service Entrance

Can someone tell me how to caculate the load in my service entrance box.
I want to add a new breaker for a new electric water heater replacing the
gas water heater I now have. However I do not want to go thru all the work
just to have an inspector tell me my service entrance will not handle the load.

Many home wiring books describe a "demand load calculation". You can also read a description here. If you get stuck, we can do the calculation for you if you answer our host of questions that we will ask.
