Electricity bills and electric costs will depend on your electric rates and how much electricity you actually use.
But for an estimate the lowest an electric bill is usually is $30.00 per month and at most could be $100.00 per month for a one person usage. Of course electricity bills can get up to $300.00 per month if you have electric heat.
I would budget at least $100.00 per month just to be on the safe side for the electric bill.
If you have electric heat then plan on $300.00 per month.
