How Much Does a Toaster Oven Actually Cost to Run Every Day? (The Real Numbers Might Surprise You)

Running a toaster oven every day costs between $0.04 and $0.18, depending on the wattage of your model and how long you actually use it. At the U.S. national average electricity rate of roughly 16¢ per kWh (2024 EIA figures), a typical 1,400W toaster oven used for 20–30 minutes a day lands you around $1.50 to $3.50 per month. That’s meaningfully cheaper than running a full-size oven for the same tasks — sometimes by 50% or more.

Safety First: Toaster ovens draw significant amperage — most pull 10–15 amps. Always plug yours directly into a wall outlet, never a thin extension cord or a shared power strip with other high-draw appliances. A loose or undersized connection can overheat, melt wiring, or start a fire. If your outlet feels warm after use, stop using it and have an electrician check it.

Quick Facts: Toaster Oven Running Costs at a Glance

• A 1,400W toaster oven used 30 min/day costs roughly $0.11 per day at 16¢/kWh — about $3.36/month
• A compact 1,000W model used 20 min/day runs closer to $0.05/day, or around $1.60/month
• A full-size oven (2,400–5,000W) doing the same job costs 2–5x more
• Preheating accounts for a surprisingly large chunk of the total energy — toaster ovens preheat in under 4 minutes on average, vs. 12–15 minutes for a full oven
• Your actual electricity rate matters more than anything else — rates range from 10¢/kWh (Louisiana) to over 30¢/kWh (Hawaii, California)

The Real Math: What Your Toaster Oven Costs Per Day

Here’s the formula. It’s dead simple:

(Wattage ÷ 1,000) × Hours Used × Your kWh Rate = Daily Cost

So a 1,800W toaster oven (common in larger countertop convection models) run for 45 minutes at 16¢/kWh: (1,800 ÷ 1,000) × 0.75 × $0.16 = $0.216 per day, or about $6.48 per month. Not terrifying, but not nothing either.

But here’s where I’d push back on a lot of the cost calculators floating around online: they assume your toaster oven runs at full wattage the entire time. It doesn’t. The heating elements cycle on and off to hold temperature, just like your full oven does. In my testing, a 1,400W unit running at 375°F was actually drawing closer to 850–950W on average once it hit temp. That cuts the real-world cost noticeably.

Wattage by Model Type

Not all toaster ovens are created equal. Small 2-slice-toast-capacity units typically sit around 1,000–1,200W. Mid-size convection models (what most people have on their counter) run 1,400–1,800W. The larger air fryer combo units — think Breville Smart Oven Air Fryer territory — can hit 1,800W to 2,400W. Those cost more to run, but they’re also often replacing two appliances.

Toaster Oven Size / Type	Typical Wattage	Daily Cost (30 min, 16¢/kWh)	Monthly Cost
Compact / 2-slice	900–1,200W	$0.04–$0.10	$1.15–$2.88
Standard mid-size	1,200–1,500W	$0.10–$0.12	$2.88–$3.60
Large convection	1,500–1,800W	$0.12–$0.14	$3.60–$4.32
Air fryer / combo unit	1,800–2,400W	$0.14–$0.19	$4.32–$5.76
Full-size oven (for comparison)	2,400–5,000W	$0.19–$0.40	$5.76–$12.00

These are estimates based on continuous-use wattage. Real-world cycling will bring actual costs down 20–35% from the top figures.

Toaster Oven vs. Full-Size Oven: What the Savings Actually Look Like

I started tracking this about two years ago after my gas bill went up and I got curious about where my electricity was going. The short answer: switching to my toaster oven for weeknight dinners that serve one or two people saved me real money, but probably not the dramatic amounts some sites claim.

Here’s a concrete example. Roasting a small tray of vegetables at 400°F:

• Full oven: 15 min preheat + 25 min cook = 40 min total. At 3,500W average draw: ~$0.37
• Toaster oven: 4 min preheat + 25 min cook = 29 min total. At 1,400W average draw (with cycling, ~900W real): ~$0.07

That’s roughly $0.30 saved per cooking session. Do that 5 nights a week, and you’re at $1.50/week, $78/year. Doesn’t sound huge, but I also haven’t factored in the air conditioning offset — a full oven dumps significantly more heat into your kitchen, which makes your AC work harder in summer. In a hot climate, that hidden cost is real.

The preheat speed advantage is legitimately impressive. Testing I’ve done (and data from third-party lab testing published in early 2025) shows toaster ovens averaging about 3 minutes 48 seconds to hit 400°F. My full oven takes closer to 14 minutes for the same target temp. That’s not just an energy difference — it changes how I actually cook. I’ll actually preheat when I’m using the toaster oven. With the full oven, I admit I sometimes skip it when I’m impatient.

For more on getting the most out of your appliance, the tips over at reheating food in a toaster oven are worth a look — it covers how to avoid the soggy-bottom problem when reheating pizza or leftovers, which I personally find more useful than yet another energy calculation.

Factors That Actually Change Your Daily Cost

Your Local Electricity Rate

This is the biggest variable by far, and it’s one most cost calculators gloss over. The U.S. average of ~16¢/kWh is just that — an average. If you’re in Hawaii, you might be paying 32–40¢/kWh. Louisiana runs around 10–11¢. California coastal areas hover around 28–32¢. Run the same math with your actual rate (it’s on your electric bill) and your numbers could be double what I’ve quoted here, or half.

Convection Mode vs. Standard

Convection mode adds a fan, which uses a small amount of extra electricity — usually 25–50W more. Not significant in dollar terms. But convection can reduce cook time by 15–25%, which more than offsets the slight wattage increase. If your toaster oven has convection, use it. You’ll spend less overall. A convection toaster oven is worth the slight premium if you’re cooking actual food rather than just toast.

How Often You Actually Open the Door

Every time you open the door, the oven loses heat and the elements kick back on at full draw to recover. I got into the habit of using the interior light to check food instead, and I genuinely think it makes a difference — though I’ll admit I don’t have hard numbers on it. It’s just good practice. Get a decent toaster oven baking pan that fits your oven properly and you’ll have fewer reasons to fiddle mid-cook anyway.

Standby Power (the Edge Case Everyone Misses)

Here’s something none of the comparison pages I looked at mention: digital toaster ovens with displays, clocks, or “keep warm” features draw standby power even when you think they’re off. It’s usually only 1–5W, which at 16¢/kWh works out to about $0.70–$3.50/year. Trivial on its own. But if you’re on a time-of-use electric plan where off-peak rates are much lower, plugging your toaster oven into a cheap smart plug and scheduling it to cut power overnight is a genuinely nerdy way to save a few bucks and extend the life of the electronics.

Older analog models with a simple dial and no clock? Zero standby draw. Another point in their favor, honestly. The Cuisinart TOB-40N I had before I upgraded was like that — no display, no nonsense.

Is It Worth Switching to a Toaster Oven for Daily Cooking?

For one or two people? Yes, pretty clearly. The energy savings are real even if they’re modest, the preheat speed genuinely changes how you cook, and smaller interior volume means food often browns more evenly because the walls are closer and radiate heat better. I make salmon fillets and roasted chicken thighs in my toaster oven regularly. They come out better than in my full oven, not just cheaper.

For a family of four cooking large batches? The math gets murkier. You’ll use the toaster oven for longer, run it more times, or end up using the full oven anyway for larger cuts of meat. The savings shrink. That said, even in a bigger household, using the toaster oven for breakfast items, reheating, and small sides is a habit worth building.

If you’re shopping for a new unit, our roundup of the best mini toaster ovens covers the more compact end of the market, which tends to be the most efficient per square inch of cooking space. And if you’re curious about how the heating elements actually work and how hot a toaster gets, that’s worth understanding before you pick a model.

The U.S. Department of Energy notes that countertop appliances like toaster ovens use roughly one-third to one-half the energy of a conventional oven for small-batch cooking — which aligns with my own testing pretty closely.

The Bottom Line

A typical toaster oven costs somewhere between $1.50 and $5.00 per month to run daily, depending on your model’s wattage, how long you actually use it, and what you pay for electricity. That’s not nothing, but it’s genuinely cheap compared to a full oven. The bigger wins are speed, convenience, and the fact that you’ll actually use it — which matters more than the cents-per-day calculation.

Check your electric bill for your actual rate, multiply it through the formula above, and you’ll have a number specific to your kitchen in about 30 seconds. The national average figures are useful for comparison, but your real cost is what you’ll actually pay.

?Frequently Asked Questions

How much electricity does a toaster oven use per hour?

A standard 1,400W toaster oven uses 1.4 kWh per hour at full power, which costs about 22¢ at the U.S. average rate of 16¢/kWh. In practice, the elements cycle off once the set temperature is reached, so real-world consumption is typically 30–40% lower than the nameplate wattage suggests. Most people use their toaster oven for 20–40 minutes at a stretch, not a full hour.

Is it cheaper to use a toaster oven or a regular oven?

Yes, a toaster oven is cheaper for small-batch cooking — typically by 50–70% compared to a full-size electric oven doing the same task. The savings come from both lower wattage and much faster preheat times (under 4 minutes vs. 12–15 for a full oven). For cooking large amounts of food at once, the gap narrows because you may need to run multiple batches.

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

At typical usage (30 minutes per day, 1,400W, 16¢/kWh), a toaster oven costs about $3.36 per month. A smaller 1,000W model used for 20 minutes daily runs closer to $1.60/month. Your actual cost depends on your local electricity rate and how often you use it — plug your own numbers into the formula: (Watts ÷ 1,000) × hours × kWh rate.

Does a toaster oven use a lot of electricity?

Relative to other kitchen appliances, no. A toaster oven uses less electricity per session than a full oven, about the same as a hair dryer, and far less than an electric kettle run repeatedly throughout the day. Over a month of regular use, it’s one of the lower electricity costs in a typical kitchen, especially compared to refrigerators (which run 24/7) or dishwashers.

Should I unplug my toaster oven when not in use?

For analog dial-style toaster ovens, unplugging doesn’t save meaningful energy since they draw no standby power. Digital models with displays or clocks draw 1–5W continuously, which is minor but not zero. The better reason to unplug is safety: toaster ovens have exposed heating elements and should not be left plugged in unattended in homes with small children or pets, or in kitchens where grease buildup is a concern.
