A 1,400 watt toaster oven costs about $0.13 to run for 30 minutes at $0.18 per kWh.
Quick estimate
This uses 1400 watts, 0.5 hours per day, and an electricity rate of $0.18 per kWh.
Toaster ovens can be cheaper than full ovens for small meals because they heat a smaller space.
Many toaster oven units fall around 1400 watts, with a rough range of 1000 to 1800 watts. Check the product label, user manual, or manufacturer specifications for the most accurate number.
| Estimate | Watts | Hours per day | Daily cost | Monthly cost |
|---|---|---|---|---|
| Low estimate | 1000W | 0.25 | $0.05 | $1.35 |
| Typical use | 1400W | 0.50 | $0.13 | $3.78 |
| High estimate | 1800W | 0.75 | $0.24 | $7.29 |
A toaster oven cycles one or more heating elements in a compact cavity. Toast, bake, broil, convection, and air-fry settings can engage different elements and fan loads.
Wattage input
Use the input rating for the appliance and treat it as the likely high draw. If your model has independently controlled upper and lower elements, a plug-in meter can show how each mode differs.
Runtime input
Include any preheat period and the full cooking session. Multiple trays or batches should be counted separately, while residual heat after shutoff consumes no additional electricity.
Convert watts to kilowatts, multiply by the number of hours used, then multiply by your electricity rate.
Cost = Watts / 1000 x Hours Used x Electricity RateFor this toaster oven example: 1400 / 1000 x 0.5 x 0.18 = $0.13 per day.
These details make this estimate more useful for real-world use.
A toaster oven heats a much smaller chamber than a full-size oven. For small meals, snacks, or reheating, that can reduce preheat time and total runtime.
If you need several batches, a toaster oven may run long enough that the savings are smaller. For a large meal, a full oven can sometimes be more practical because it cooks more food at once.
Use the toaster oven for small portions instead of preheating a large oven.
The easiest way to improve the estimate is to replace the default values with your actual wattage, average runtime, and local electricity rate.
Wattage ranges are practical planning estimates for common household appliances. Actual use can differ by model, age, settings, room conditions, and maintenance.
These authoritative sources support the calculation method, default electricity-rate benchmark, and appliance-specific operating context. The wattage range remains a planning estimate; use the nameplate on your own appliance for the most accurate input.
Used to benchmark the rounded default residential electricity rate. Your utility bill remains the best source for your own rate.
Supports the watts-to-kWh calculation method and the recommendation to check the appliance nameplate or use a power meter.
It often has an advantage for small meals because its cavity preheats faster and the cooking session may be shorter. The result depends on food quantity, temperature, and repeated batches.
