To figure it all out you need to know what your electric company charges.
It is usually listed on your bill for kwh.
Then you need to determine how long each device is running per day.
If your 37 w bulb is burning 10 hours a day it is comsuming 370 watts per day * 30 days in a month = 11.1 kw
So if you are charged $.10 per kwh your light will cost you $1.10 per month
