How much does heating your snake room affect your bill?

I use an oil-filled heater as well. The trailer is incredibly drafty. The snake room has a hole in the corner because the whole trailer is twisted (whoever put the trailer here didn't know how to set it up right), and the bathroom is separating from the trailer. Over the winter I tacked a blanket up over the window, and laid blankets over the bottom of the bathroom and the bedroom door, and it only helped marginally. Between the snake room heater, our monitor heater, and the two bathroom heaters, our bill goes up from $100-120 in the summer to ~$175 in the winter (this is based off one winter and this spring/summer). I set the heater to 85F over the winter because the room is so drafty that most of the heat is swept out, so certain parts of the room is 74-80F and other parts are 85-88F. I have no clue what our power bills were like at the apartment, didn't bother to ask.
