the double size washers are the smallest size and they are $2.75/load. The 4x size is $3.50/load. the 6x size is $4.75/load and the 9x size is like $6.50/load. the washers are beasts and do an awesome job and the hot water is actually hot. the dryers are .25 per 5 minutes of dry time and are also pretty efficient. i try to get the dryers that have been used most recently that way they are already warmed up.
Depends on the size of washer or dryer you use. They have multiple load size units. I think the smallest washer is like $4.00 and the dryers are timed per the amount of money you put in them.
