average cost of washing and drying clothes
Rating Newest Oldest. Best Answer: Where I am, it costs about $1.50 to wash and $1.50 to dry. Those are for normal-sized washers. For a family of 4, I spend between $80 and $100 on the machines each month. Ouch. The region you're in will have a lot to do with how much you pay.uch, much, much cheaper. You can get a bottle of cheap detergent for about $3-$6 (depending on the size), and a box of store brand dryer sheets for about $2 or $3 that will last months (about 40 to 70 dryer sheets per box).
