What figures were you using? I'd like to put the current New South Wales, Australia electricity price into the equation.
My calculations are here[1]. Basically, $2/1000 gallons of water & $0.10/kWh for electricity (I did not bother calculating for gas dryers) were the most recent US averages I could find, and that was rounding up (e.g., electricity was actually > $0.09 but I used this calculator[2], and plugged in appropriate values where I could find most current data.

Even with lowball estimates, my cost for washing is double yours - 30+c/kWh... sigh.
