How much will your electric bill increase if you buy an electric dryer for an average of 5 loads per week?

About $10.

Do the math. Amps x Volts = Watts. A typical dryer is 30 amps @ 240 volts. That's 7200 Watts. Average electricity cost is $.07 per 1000 watt-hours. So...if you run the dryer for one hour will use 7200 watt-hours. 7.2 x $.07 = $.50 per hour of usage.
