As of 2013, the weekly cost to wash and dry two loads of laundry at a laundromat is about $6, not including cleaning products or travel costs. The Simple Dollar notes that it costs about $3 per load of laundry washed and dried in a laundromat.
When washing clothing at home, consumers pay about 36 cents for the energy to run the washing machine for one load of laundry, 40 cents for energy for the dryer and 11 cents for water. The estimate does not include cleaning products or equipment costs.
The average cost of a washing machine is about $700. It has a lifespan of about nine and a half years, assuming that one load of clothing is washed per day. A dryer costs about $600 and lasts about 11 years. Based on the savings by washing at home versus at a laundromat, it takes about 610 loads of laundry to recoup the cost of purchasing a washer and dryer.
