How much does it cost to run a toaster oven?
We've pre-filled a typical toaster oven below. Set your electricity rate and adjust the hours to match how you use yours — the cost updates instantly.
A toaster oven is the appliance you reach for specifically to avoid heating up the big oven, and the electricity bill backs that instinct up. At 1,000-1,500 watts it draws roughly the same power as a hair dryer or a space heater — but you're only running it in short bursts to reheat a slice of pizza or bake a small tray of fries, not for hours at a stretch. That's the whole story here: the wattage looks high on paper, but the runtime is so short (most people use one well under 30 minutes a day) that the actual monthly cost stays low.
Where people get surprised is when the toaster oven quietly becomes their everyday oven — reheating leftovers, making toast, cooking a full dinner for one — because those extra 10-minute sessions add up faster than a single big Sunday roast in the full-size oven ever would. Preheating less (toaster ovens heat up fast, so most jobs don't need it) and matching the pan size to the job are the two habits that keep this appliance as cheap as it's supposed to be.
What drives the cost of running a toaster oven
- Wattage: most toaster ovens draw 1,000-1,500W (this calculator defaults to 1,200W), squarely in space-heater territory, but only while actively heating
- Runtime per use: sessions are typically short (reheating, toasting, small bakes), which is why the default assumption here is just 0.5 hours a day — far less than a full-size oven sees
- Mode and temperature: broiling or running at higher temperatures for longer draws more power than a quick toast or warm cycle
How to cut it
- Skip preheating for short jobs (toast, reheating) — toaster ovens heat up in 1-2 minutes, far faster than a full oven, so a full preheat cycle is often wasted energy
- Use the toaster oven instead of the full-size oven whenever the job fits — you get the same result at a fraction of the wattage-hours
- Match the setting to the job: broil/high-heat functions pull more watts than the standard bake or toast setting, so use the lowest mode that gets the job done
- Batch small cooking tasks into one session instead of running short back-to-back cycles, since each start-up spends a bit of energy getting to temperature
Common questions
How much does it cost to run a toaster oven per month?
At a typical 1,200W and about 0.5 hours a day, a toaster oven costs roughly $3.06 a month at $0.17/kWh. Set your own rate and hours above for an exact figure.

Is a toaster oven cheaper to run than a full-size oven?
Yes, for small jobs. A toaster oven's smaller cavity heats up faster and holds less air, so it uses less energy than a full-size oven to cook the same small item — that's true even though its wattage (1,000-1,500W) isn't dramatically lower than an oven's. The savings come from shorter preheat and cook times, not a lower wattage rating.
Does toasting bread cost less than a full bake or broil cycle?
Yes. Toasting runs the heating elements for just a few minutes at a fixed setting, while baking or broiling holds the oven at temperature for much longer. A few minutes of toasting costs a fraction of a cent; a 20-30 minute bake at 1,200W adds up to real (if still modest) money over a month.
