How Much Does a Dishwasher Cost to Run?

A dishwasher’s electricity cost depends on the cycle, duration, heating requirements, and how often it is used. Electric water heating can be an important part of total energy use.

Suppose a dishwasher averages 1,200 watts during a 1.5-hour cycle and is used 20 times per month. That is about 36 kWh. At $0.16 per kWh, the estimate is $5.76 per month.

This is an example, not a universal figure. Actual use varies by machine and cycle.

Calculate the cost per cycle and multiply it by your normal monthly usage. Compare cycle energy information when available rather than assuming a longer cycle is always more expensive.
