Most of us look at it every day but did you ever got to wonder how much energy does your toaster use? You obviously did since you’re reading this and I wouldn’t hold you back any longer. I’m curious myself so I’ll save us all the trouble and get to the point.

In this article, I’ll go through common toaster wattages, how much power they consume in a year, and teach you how to calculate it on your own.

How Many Watts Does a Toaster Use?

The power consumption of a toaster differs with each model. Common 2-slice toasters use anywhere between 800 and 1400 Watts while 4-slice toasters can use up to 1800 Watts. For most accurate info it’s best to check your toaster’s manual.

2-Slice Toaster Energy Consumption in a Year

To better understand how many watts does a 2-slice toaster use here’s a breakdown of possible yearly power consumption. I included the most common wattages for this type of toaster.

For the yearly charge, I took the average kWh price in the United States.

WattsDaily UsageWorking Hours (Year)kWh Per YearYearly Cost
8002 Min (2 Slices)~129.6 kWh$1.3
9002 Min (2 Slices)~1210.8 kWh$1.5
10002 Min (2 Slices)~1212 kWh$1.6
11002 Min (2 Slices)~1213.2 kWh$1.8
12002 Min (2 Slices)~1214.4 kWh$2
13002 Min (2 Slices)~1215.6 kWh$2.1
14002 Min (2 Slices)~1216.8 kWh$2.3
Yearly kWh cost for using a 2-slice toaster.

Table Breakdown:

Let’s say you’re using your toaster to make 2 slices of bread each day. Since this is a 2-slot toaster it would be one run, averaging 2 minutes. Everyday usage of 2 minutes would result in around 12 working hours per year.

For the yearly cost calculation, I used the national average of 13.50 cents per kWh.

4-Slice Toaster Energy Consumption in a Year

To better understand how many watts does a 4-slice toaster use here’s a breakdown of possible yearly power consumption. I included the most common wattages for this type of toaster.

For the yearly charge, I took the average kWh price in the United States.

WattsDaily UsageWorking Hours (Year)kWh Per YearYearly Cost
15004 Min (4 Slices)~2436 kWh$4.9
16004 Min (4 Slices)~2438 kWh$5.2
17004 Min (4 Slices)~2441 kWh$5.5
18004 Min (4 Slices)~2443 kWh$5.8
Yearly kWh cost for using a 4-slice toaster.

Table Breakdown:

Let’s say you’re using your toaster to make 4 slices of bread each day. Since this is a 4-slot toaster it would be one run, averaging 4 minutes. Everyday usage of 4 minutes would result in around 24 working hours per year.

For the yearly cost calculation, I used the national average of 13.50 cents per kWh.

Calculate Toaster Energy Consumption

There’s a simple formula you can use to calculate kWh for your toaster. Once you have that number you can multiply it with kWh price in your state and work out an annual cost.

kWh = Watts x Time (Hours) / 1000

Multiply your toaster wattage with working hours in a particular time frame. Afterward, divide it by 1000 and you’re left with kWh for the given period.

Are Toasters Energy Efficient?

For their particular purpose, toasters are energy efficient. No other appliance will make toasted bread and consume less energy while doing it.

Does Unplugging Your Toaster Save Energy?

Unplugging your toaster can save small amounts of energy. A variety of appliances can consume electricity when plugged in, despite being turned off. However, the common practice of unplugging toasters has more to do with safety, rather than energy saving.

Modest Spending, Extraordinairy Pleasure!

The ROI on the toaster is just amazing! It doesn’t consume much energy annually and the number of perfect breakfasts you got is uncountable! It gets even better now when you know your breakfast is also eco-friendly!
