By far AC is the largest consumer of juice, however there are a number of items that consume power all the time (ghost watts) averaging 100 to 200 watts 24/7 or 73.2 to 146.4 kWH monthly.
To quote dollars to operate an appliance is somewhat misleading depending upon your utility but you can be reasonably accurate at .112 cents per kWH. So my AC costs $55.56 this month not including customer charges, taxes and other fees.
Data based upon a whole house energy monitor collecting 100,000 points of data per second for six years or 18.9 trillion points of reference.
Any questions on energy consumption in TV, ask away.
TLDR: no your bill is not high.

Toymeister,
With great respect for your abilities, I have had difficulties matching your calculations using your data. The problem seems to be what is the AC power consumption instantaneous versus average over the month.
"exactly 496,120,000 watts or 496.1 kWH" I assume you meant watt-hours for the month. If so, I can match your monthly power cost. Otherwise I get a number about double suggesting that somewhere the average daily runtime and the absolute 24 hrs per day times 30 days per month somewhere got missed or I misunderstood.
Trying to calculate the kwh starting with the AC power draw:
Assuming AC power draw is 2927 watts or 2.927 kw when operating, and assuming 11 hrs per day times 30 days per month I get 981 kwh/mo.
At $0.112 per kwh, the monthly cost would be about $110.
Going back to: 496.1 kwh consumed times $.112 per kwh = $ 55.6
I agree with your comments and analyses. I agree that the OP cost is reasonable for all of the points you mentioned, other fees, ghost loads etc. The student in me could not make the quick numbers match.
