What Does It Cost to Run a Dishwasher in Connecticut?
Running a dishwasher in Connecticut costs about $14.51 a month — $176.51 a year — at the state's average rate of 32.24 ¢/kWh. That's roughly $70.74 a year more than a household paying the national average pays for the exact same dishwasher. The estimate assumes a typical 1,500-watt dishwasher running 1 hours/day, at the all-in average rate (delivery, fixed charges, and utility fees already included; locally billed taxes vary by area).

Dishwasher cost vs U.S. average
At the state average rate, a dishwasher in Connecticut costs $5.81 more a month than it would at the U.S. average rate.
How much electricity does a dishwasher use?
A dishwasher draws roughly 1,200-1,800 W; we use 1,500 watts running 1 hours/day. That comes to 1.50 kWh a day — 45.0 kWh a month, or 547.5 kWh over a year — using kWh = watts × hours ÷ 1000.
Most of a dishwasher's electricity goes to heating water, not spinning the spray arms — so a hot 'sanitize' or 'heated dry' cycle costs noticeably more than a quick eco wash. Connecticut prices that energy at 32.24 ¢/kWh, against a 19.32 ¢/kWh national average.
Dishwasher operating cost estimate in Connecticut
| Time period | Energy use | Cost |
|---|---|---|
| Per hour | 1.50 kWh | $0.48 |
| Per day | 1.50 kWh | $0.48 |
| Per month | 45.0 kWh | $14.51 |
| Per year | 547.5 kWh | $176.51 |
These figures use the all-in average rate. Your actual bill can run higher when separately billed taxes, seasonal pricing, and fixed monthly fees apply.
What changes the cost the most?
Two things move this number: your state's rate, which you can't change, and how hard the appliance works, which you often can. For a dishwasher, that mostly comes down to heated dry setting, eco mode, number of cycles per week.

Source: U.S. Energy Information Administration (EIA) Retail Sales of Electricity. Updated: April 2026. Estimates use the EIA all-in average residential rate — energy, delivery, fixed charges, and utility fees together, not just the electricity itself. Fees are inside the rate, not an extra on top; how your own bill splits fixed versus per-kWh charges varies by utility.
