Will a Mini Fridge cause my electric bill to be considerably higher?

I've got a roommate who wants a mini fridge for his room. Its one of the larger ones, probably a little under 3 cubic feet. About how much will this raise our electric bill?|||it depends on how often you open it.but warm beer or refreshments v,s chilled for $5 a month.it would be worth every cent|||probably about $5 a month|||If its a newer one,not much.Just check with the wattage from this month.If it is the only new appliance you will know next month.They are really cheap to run,everyone has them in dorms...|||It doesn't use as much as a box fan. I know of Older people that use only the mid size dorm fridge. because they let the store store their food and the buy it as they need it. like enough for two days. They also use the weekly ad as a menu as to what is for dinner. Large fridges are a energy waste and even worst are the big freezers. The proof in this is that when it comes time to clean out the fridgeees. Look at how much money goes to the trash. Big fridg, big money, little fridg, little money, real simple.
