Quick answer
Based on 1400W at a 80% duty cycle (this equipment cycles on and off rather than drawing full power continuously) and 19.52¢/kWh, the Ohio average for May 2026.

Why the cost differs in Ohio
Ohio has the 34th cheapest residential electricity of the 51 US states and territories we track, at 19.52¢ per kWh against a national average of 18.44¢. That is +5.9% compared with the national figure. Ohio has a competitive retail market, so households can shop for supply and published averages blend many different contracted rates. PJM capacity costs are the main upward pressure on bills rather than fuel. The climate delivers a genuine dual peak, with cold winters and humid summers both contributing substantially to annual consumption.
For this appliance specifically, the difference works out to an extra $1.32 a year over what the same toaster oven would cost at the national average rate. Run the identical appliance in Hawaii and it would cost $63.77 a year; in Idaho it would cost $15.15. That spread of $48.63 is entirely down to location.
That works out to roughly 1.2% of a typical Ohio household's annual electricity bill - modest individually, though appliances in this range add up.
Ohio sits above the national average, so the running cost of this toaster oven is modestly higher than a typical US household would pay. Usage habits still matter more than location at this rate level.
Because Ohio has retail supplier choice, the state average blends many different contracted rates. If you have shopped for a plan, your own price per kWh is the number to put in the calculator.

| US average | 18.44¢ | $1.89 | $22.61 |
| Idaho cheapest state | 12.35¢ | $1.26 | $15.15 |
| Hawaii most expensive | 52.00¢ | $5.32 | $63.77 |

About running a toaster oven
For small items a toaster oven costs roughly a third of what a full-size oven does, since it heats a much smaller cavity and needs little or no preheat. The saving disappears once you are cooking enough food to fill a full oven rack.
What actually changes the cost
- If your utility offers time-of-use pricing, shifting this load off-peak can cut its cost substantially without using any less energy.
How we worked this out
The arithmetic is simple and we would rather show it than hide it. Divide watts by 1,000 to get kilowatts, multiply by hours of use and by the duty cycle to get kilowatt-hours, then multiply by your rate:
1400W ÷ 1000 × 0.3h × 80% = 0.336 kWh/day × 19.52¢ = $0.066 per day
One honest caveat: Ohio’s figure is a state average published by the EIA. Your own utility’s tariff, any time-of-use pricing, fixed monthly service charges and local taxes all shift the real number. Put your actual per-kWh rate into the calculator above for a figure that reflects your bill.
Questions about toaster oven running costs
How many watts does a toaster oven use?
A typical toaster oven draws about 1400 watts while running, with most models falling between 1000W and 1800W. Check the nameplate label or manual for your specific unit - the range is wide enough that averages can mislead.
How much electricity does a toaster oven use per day?
At around 0.3 hours of use a day and a 80% duty cycle, that works out to roughly 0.34 kWh per day, or about 10 kWh a month. Your actual figure depends on your usage and model.
Why does the cost differ so much between states?
Residential electricity rates across the US range from about 12.35 cents per kWh in North Dakota to 46.62 cents in Hawaii - nearly a fourfold difference. The same toaster oven, used identically, therefore costs almost four times as much to run in the most expensive state as in the cheapest.
Is it cheaper to run a toaster oven at night?
Only if you are on a time-of-use or variable tariff. On a flat rate, the time of day makes no difference to cost. If you are on time-of-use pricing, off-peak hours are typically materially cheaper, and shifting this load can reduce its cost without reducing usage.
