A tiny daily expense
Most two-slice toasters use around 800 to 900 watts. Since it only takes a couple of minutes to toast bread, the total electricity used is incredibly small. You would have to make toast for hours to see a real difference on your bill.
Four-slice models
Larger toasters draw more watts, often up to 1,500. However, they toast twice as much bread in the same amount of time, so the cost per slice stays exactly the same.
Vampire power
Some digital toasters draw a tiny amount of standby power when plugged in. If you want to be completely efficient, unplug it when you are done with breakfast.
Rate source and limits
The default rate is the EIA U.S. residential average for April 2026, retrieved July 16, 2026. It is an average revenue per kilowatt-hour, not a quote for your utility plan. Fixed fees, taxes, tiers, and time-of-use prices can change the bill.
