Though the amount of an average electric bill for an apartment varies based on utility prices and usage, the typical apartment dweller spends $30 to $50 on electricity each month, based on 2014 figures not including AC use. The use of air conditioning significantly increases electricity costs.
Electric bills are generally lower during the winter months and for apartments in cool climates, as those conditions minimize air conditioning usage. On average, air conditioning use during the summer months can increase a monthly electric bill by $50 to $80. In hot climates, such as Arizona and southern California, air conditioning costs can add $80 to $90 to the monthly apartment electric bill.
