Calculate your cost
Start with the example below, then replace the wattage, daily runtime, and rate with the numbers for your toaster.
This setup uses about 3 kWh in a 30-day month.
Please enter valid values within the ranges shown.
| Schedule | Hours/day | Cost/month |
|---|---|---|
| Half runtime | 0.05 | $0.25 |
| Page example | 0.1 | $0.51 |
| Longer runtime | 0.15 | $0.76 |
Same 900-watt input and 18.83¢/kWh rate; only runtime changes.
Formula for the page example
0.9 kW × 0.1 hr × $0.1883 = $0.02 per day
Convert watts to kilowatts, multiply by the active hours used each day, then multiply by the electricity price in dollars per kWh. Multiply the daily result by 30 for the monthly estimate shown above.
How to read this estimate
Toasters use exposed heating coils that draw intense heat for just a few minutes. You hardly notice the cost on your monthly bill.
Use this as a baseline until you can check the label or measure the toaster directly. Model, settings, condition, climate, and household routine can all change the result.

Ways to spend less
- Toast multiple slices at the same time if you have a larger unit.
- Keep the crumb tray clean to prevent burning smells and inefficiency.
- Unplug the toaster when not in use.
