Toaster vs Toaster Oven: Which One Actually Costs Less to Run Every Month?

A standard toaster costs roughly $0.50–$1.50 per month to run, while a toaster oven runs closer to $3–$8 per month depending on how heavily you use it. The gap exists because toaster ovens draw more watts and run for longer cycles — but the full picture is more complicated than that, and for some households the toaster oven actually wins on total energy spend. Here’s how to figure out which one makes sense for your kitchen.

Safety First: Never leave a toaster or toaster oven unattended while in use. Both appliances draw significant current and can overheat if crumbs accumulate in the tray or if ventilation is blocked by cabinet walls or dish towels. Empty the crumb tray weekly, keep at least 4 inches of clearance on all sides, and always unplug before cleaning.

Quick Facts: Toaster vs Toaster Oven Electricity Cost

• A typical 2-slice toaster draws 800–1,200 watts but only runs for 2–4 minutes per use, so the actual energy consumed is tiny.
• A toaster oven draws 1,200–1,800 watts and runs 15–30 minutes per cooking session — that’s where the cost gap opens up.
• At the U.S. average electricity rate of roughly $0.16 per kWh, toasting two slices of bread costs about $0.004 per cycle.
• Using a toaster oven to replace full oven cooking can cut energy use by 30–50% on those specific tasks — a potential monthly saving of a few dollars.
• The edge case most articles miss: air fryer-style toaster ovens with fans often finish jobs faster, which can actually make them cheaper per meal than a standard toaster oven despite their higher wattage rating.

The Raw Numbers: Wattage, Time, and What You Actually Pay

Let’s do the math properly instead of waving vaguely at “energy savings.” The formula is simple: Watts ÷ 1,000 × hours used × your electricity rate = cost. That’s it.

Say you toast two slices of bread every morning. Your toaster pulls 1,000 watts and the cycle takes about 3 minutes (0.05 hours). That’s 0.05 kWh. At $0.16 per kWh, that’s $0.008 per day, or roughly $0.24 per month. Add a weekend bagel or two and you’re still under $0.40.

Now for the toaster oven. I’ve got a Breville Compact Smart Oven that pulls 1,800 watts. If I use it for 25 minutes to roast vegetables — which is a pretty typical session — that’s 0.75 kWh, or about $0.12 per cooking session. Run it once a day and you’re at $3.60 per month. Use it for two or three meals daily and that climbs toward $7–$8 without breaking a sweat.

So on pure appliance-to-appliance comparison? The toaster wins easily. But that framing ignores something important.

The Comparison That Actually Matters: Toaster Oven vs Full-Size Oven

Nobody uses a toaster oven instead of a pop-up toaster. They use it instead of heating a full 5,000-watt electric oven to bake four chicken thighs or reheat leftover pizza. That’s the real comparison, and here the toaster oven looks very different.

A large electric oven preheats for 15–20 minutes before you even put food in. A toaster oven — especially a convection model — is ready in 5 minutes. For small jobs, you’re looking at roughly half the total energy consumption when you switch from your main oven to a countertop unit. The U.S. Department of Energy has noted that cooking appliances account for a meaningful chunk of home energy use, and reducing preheat time is one of the most practical ways to cut that.

I did a rough real-world test on this in my own kitchen. Reheating a slice of lasagna in my full oven: about 35 minutes total (preheat plus heat-through), which at 4,500 watts average draw works out to roughly 2.6 kWh — about $0.42. Same lasagna in the toaster oven: 18 minutes at 1,800 watts = 0.54 kWh, or $0.09. That’s not a rounding error. It adds up fast if you’re cooking this way every day. For more on reheating food in a toaster oven efficiently, I’ve got a full breakdown elsewhere on the site.

Model-by-Model: How Much Does Each Type Actually Draw?

Not all toaster ovens are equal, and wattage varies a lot. Here’s how some popular models shake out in terms of power draw and what that means for your bill.

Appliance / Model	Wattage	Typical Session Length	Est. Cost Per Session	Est. Monthly Cost (1x daily)
2-Slice Pop-Up Toaster (average)	900–1,200W	3–4 min	$0.01	$0.25–$0.40
Hamilton Beach 4-Slice Toaster Oven	1,200W	15–20 min	$0.05–$0.07	$1.50–$2.00
Cuisinart TOA-70 Air Fryer Toaster Oven	1,800W	15–25 min	$0.07–$0.12	$2.10–$3.60
Breville Smart Oven Air Fryer Pro	1,800W	15–25 min	$0.07–$0.12	$2.10–$3.60
Ninja Foodi XL Pro Air Oven	1,800W	12–20 min (fan-assisted)	$0.06–$0.10	$1.80–$3.00
Full-Size Electric Oven (for context)	3,500–5,000W	35–60 min (incl. preheat)	$0.19–$0.48	$5.70–$14.40

The Ninja’s slightly lower effective cost despite matching wattage is because the convection fan cuts cooking time noticeably. I’ve used the Ninja Foodi XL Pro and the Breville side by side, and the Ninja genuinely does finish chicken wings about 4–5 minutes faster at the same temperature. That’s not marketing — it matters for the electricity bill.

The Breville Smart Oven Air Fryer Pro is the one I’d pick if money weren’t the deciding factor — better build quality, more accurate thermostat, and the interior light is actually bright enough to see what you’re doing. The Cuisinart TOA-70 is a solid mid-range pick that costs less upfront and runs fine for everyday use. Hamilton Beach is budget territory, and it shows in how unevenly it toasts, but if you’re mostly reheating leftovers, it does the job.

The Edge Case Everyone Misses: Standby Power and Phantom Load

Here’s something the other articles on this topic skip entirely. Some toaster ovens — particularly the digital ones with clocks, preset timers, or “keep warm” functions — draw a small amount of power even when they’re not cooking. This is called standby or phantom load. It’s usually only 1–5 watts, but over a month it can add $0.07–$0.60 to your bill. Not dramatic. But if you’ve got three or four plug-in kitchen appliances all doing this, it stacks.

Standard pop-up toasters, by contrast, draw essentially zero power when idle. No clock, no display, nothing running. This is actually one genuine argument in favor of a simple toaster for bread-and-bagel households — it’s completely passive when you’re not using it.

The fix for toaster oven standby draw is boring but effective: plug it into a smart outlet or a simple power strip you switch off. I use a cheap switched strip for my toaster oven and it’s become second nature to flip it after cooking. Takes two seconds.

Which Should You Actually Buy? An Honest Verdict

If you mostly make toast, bagels, and the occasional English muffin — a pop-up toaster is cheaper to run, faster, and takes up less counter space. Full stop. The temperatures a toaster reaches are more than adequate for browning bread evenly, and there’s no reason to overcomplicate it.

But if you’re using your full oven more than three or four times a week for small meals, switching those cooking sessions to a toaster oven will likely save you money on net, even accounting for the toaster oven’s higher per-session cost. The monthly energy bill math tips in its favor pretty quickly.

For most households that do both — toast in the morning, actual cooking in the evening — the answer is to own a pop-up toaster for bread and a mid-range toaster oven for everything else. That’s genuinely the most cost-efficient setup. Check out my picks for the best mini toaster ovens if you’re tight on counter space; some of the compact models perform surprisingly well and draw less power than their full-size siblings.

If you’re buying a toaster oven specifically to save money, go convection. The fan-assisted models like the Ninja Foodi and Breville Air Fryer Pro genuinely cut cooking times by 20–30%, which translates directly to lower electricity use per meal. You’ll also want a decent toaster oven baking pan — the ones that come in the box are often thin and warp at high heat, which is a minor annoyance I didn’t anticipate when I first got my Breville.

Serious Eats has a good breakdown of convection cooking principles if you want to understand why airflow affects cooking time — worth reading if you’re nerdy about this stuff.

The Bottom Line

A toaster costs almost nothing to run — we’re talking under $0.50 a month for typical use. A toaster oven costs more per month in absolute terms, but if it’s replacing your full-size oven for small cooking jobs, it saves you money overall. The two appliances are solving different problems, which is why comparing their electricity costs directly is a bit like comparing your car’s fuel use to your bicycle’s. Both have a place.

Buy a pop-up toaster for toast. Buy a convection toaster oven for cooking. Unplug the toaster oven when you’re not using it if it has a digital display. And don’t bother heating a 5,000-watt oven to reheat two slices of pizza. That one habit alone pays for a decent toaster oven in about six months.

?Frequently Asked Questions

How much electricity does a toaster use per month?

A standard 2-slice toaster used once daily for toast costs roughly $0.25–$0.50 per month in electricity at the average U.S. rate of $0.16 per kWh. Each individual toasting cycle uses so little energy — typically under 0.01 kWh — that it barely registers on your bill. Even heavy daily use rarely pushes the monthly cost above $1.

How much does it cost to run a toaster oven every month?

A toaster oven used once daily for 20-minute cooking sessions costs roughly $3–$5 per month at average U.S. electricity rates. Use it for multiple meals a day and that can climb to $7–$10. The exact number depends on your model’s wattage (most fall between 1,200 and 1,800 watts) and your local electricity rate.

Is a toaster oven cheaper to run than a regular oven?

Yes, significantly — for small cooking tasks, a toaster oven typically uses 30–50% less energy than a full-size electric oven on the same job, mostly because it preheats faster and the smaller cavity heats up more efficiently. If you’re cooking a Thanksgiving turkey, obviously the full oven wins by necessity, but for anything that fits in a 6–12 quart toaster oven interior, the countertop appliance is cheaper to run.

Does a toaster oven use more electricity than a toaster?

Yes — a toaster oven uses more electricity per month than a pop-up toaster in almost every real-world scenario. Toaster ovens have higher wattage ratings and run much longer per cycle. That said, the right comparison isn’t toaster vs. toaster oven; it’s toaster oven vs. full-size oven, where the toaster oven wins convincingly.

Should I unplug my toaster oven when not in use?

It’s a good habit, especially for digital models with clocks or displays that draw 1–5 watts continuously even when idle. Over a year that phantom load can add $0.50–$3 to your electricity bill — not enormous, but pointless. More importantly, unplugging reduces fire risk from electrical faults in an appliance that contains heating elements.
