As of 2014, the cost of running an energy-efficient, front-loading washing machine is approximately $85 annually in energy costs, plus the cost of about 15 gallons of water per load. The cost of water and electricity may vary slightly by region.
A top-loading washing machine uses more energy and water than a front-loading washing machine. Energy costs per load may be as much as double when using a top-loading washing machine. A top-loading washing machine also uses as much as 50 gallons of water per load, depending on the setting used. The cost per 1,000 gallons of water in the United States averages $1.50, in addition to any fees and taxes charged by local municipalities. Washing in cold water may be more cost efficient in both front- and top-loading washing machines.
