How much does it cost to run a dishwasher in California?

$83/yr · median certified model

Electricity in California is genuinely expensive — 34.7¢/kWh, 89% above the national average — so the median certified dishwasher costs about $83 a year, and efficiency differences between models turn into real money.

California sits at rank 50 of 51 — near the very top of the cost table for a dishwasher. At local rates, certified models span $28 (Loch L1126) to $83 (Amana ADFS2524R) per year — $56 of annual headroom that depends entirely on which unit you buy. For reference, the national extremes are Nevada (13.1¢/kWh) and Hawaii (52.7¢/kWh); the same median dishwasher would cost $31 and $126 a year there.
