How much electricity does a toaster use?

Depends on the model and the electricity meter because these things aren't 100% -- not an electrical person.

The Hamilton Beach 2-slice toaster that I have apparently burns about 830 watts. I just played with the toast and darkness settings. Maybe the other two buttons for bagels do something. There didn't appear to be a difference in power consumption between just turning the toaster on and turning it on with the "toast" button pushed. Also, the number setting for the darkness of the toast only seemed to act like a timer.

Cost per year
At $0.10/kWh, a power consumption of 830 W translates to 0.83 kW. At 24 hours a day, 365 days per year, that is 0.83 kW x 24 (h/day) x 365 (day/yr) x $0.10 (/kWh) = $727.08 (/yr). I'd really like to know who needs to toast 24/7/365.

For two slices of toast, it usually takes less than 5 minutes. I only have time to make toast on weekends and off-days. On average, that's two or three times a week.

Oh well, gives you an idea of what a space heater or water kettle costs to run year round. Those actually are turned on 24/7/365, but they have periods of off-time.
