According to the California Energy Commission an average clothes dryer will cost in the range of $1,500 to operate over an 18 year lifespan. Regardless of the type of dryer, or the method of power (gas or electric), a dryer will operate the same - using artificially forced hot air to dry clothes. According to the U.S. Department of Energy a clothes dryer uses 6 percent of household electricity per month; Memphis Light, Gas and Water Division translates this into $7 per month using one load per day. If you think using the laundromat dryers are cheaper, think again. Even if you only do three loads per weekly trip you spend $3.75 per week ($15 per month).
