Common questions
Answered from the data on this page.
How much does it cost to run a microwave per month?
At the typical usage for this appliance (1,000 W for 0.5 h/day ≈ 15 kWh/month), the median across US states is about $2.48 per month as of June 2026. Your state and actual usage move the number — the calculator above lets you change both.
Which states are most and least expensive to run a microwave?
Most expensive: Hawaii at about $8.02 per month. Least expensive: Nevada at about $1.99. The spread comes from residential rates alone (latest EIA month) — the appliance draws the same power everywhere.
How much does a microwave cost per hour?
About $0.16 per hour at the median US residential rate of 16.32¢/kWh (1,000 W draw). Cost per hour never varies by state as much as monthly bills do — hours of use drive the total.
Method: cost = wattage × hours/day × 30.44 days × state average residential rate (EIA-861M, June 2026). Your utility's fixed charges, tiered rates, and time-of-use plans change the real invoice — see the methodology.
