Microwave cost vs U.S. average
At the state average rate, a microwave in Delaware costs $0.05 less a month than it would at the U.S. average rate.
How much electricity does a microwave use?
A microwave draws roughly 600-1,500 W; we use 1,200 watts running 0.25 hours/day. That comes to 0.30 kWh a day — 9.00 kWh a month, or 109.5 kWh over a year — using kWh = watts × hours ÷ 1000.
Microwaves draw meaningful power when running, but short cooking times keep total monthly cost relatively low. Delaware prices that energy at 18.79 ¢/kWh, against a 19.32 ¢/kWh national average.
Microwave operating cost estimate in Delaware
| Time period | Energy use | Cost |
|---|---|---|
| Per hour | 1.20 kWh | $0.23 |
| Per day | 0.30 kWh | $0.06 |
| Per month | 9.00 kWh | $1.69 |
| Per year | 109.5 kWh | $20.58 |
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 microwave, that mostly comes down to daily use frequency, power setting, meal prep habits.
