Those 109 kWh are billed at 14.1¢–24.7¢, against a 24.2¢ whole-bill average on the median plan: they land in the last tier the household reaches, so the average rate understates them by up to 0.5¢ per kWh.
What Michigan homes use
EIA's 2020 residential survey found 109 kWh a year across 269 sampled homes that run one, near the national 112 kWh. The middle half spans 42 kWh to 149 kWh, so a dishwasher varies by 106 kWh between one household and another.
The dishwasher's motor, controls and internal heater, including the heated dry cycle where one is used. That average covers homes with a dishwasher — 67% of homes here.
That makes a dishwasher about 1% of the electricity a Michigan home uses. The remaining 8,261 kWh is what a dishwasher is billed on top of, and on a tiered or time-of-use plan that is what sets the rate it meets.
Light and heavy use of a dishwasher
