Apartment is just shy of 800 square feet and is 1 bedroom 1 bath.Has electric water heater, furnace, stove, microwave, fridge, dishwasher.Now l plan on using the stuff reasonable and turning the furnace down at night to prolly (62-64).l will most likely have my computer on everyday also but not 24/7. Anyone have a similar setup in michigan that can give me some incite as to what to expect on my bill.The office said they average $80 and are obviously higher in the winter, but how much higher?

This is impossible to answer, too many variables. Depends on usage, energy star rating on the appliances, etc.

The only suggestion l can offer is this: When it comes to heating (applies to A/C, as well) it is usually cheaper to set a temperature & leave it alone. Let is say u set ur heating for 70 at night, then turn it off during the day. You will use more energy to heat the place back up, then u would use if u had just left it at 70 a maintained the temperature.
