An average household juggles multiple appliances in the kitchen, from blenders to hoods and oven simultaneously.

While this is often necessary, skyrocketing energy prices prompt concerns about power costs of using these kitchen appliances.

What’s the solution? 

Using your appliances less frequently to reduce energy bills? 

Is there any better way? 

Yes; Opting for more energy-efficient appliances.

These days many are turning to air fryers as they gain popularity as energy-efficient alternatives. 

Yes, air fryers are energy efficient when compared with the energy cost of larger ovens (gas or electric) and deep fryers in the house. According to the recent estimates of Utilita — a UK-based electricity and gas supplier, air fryers don’t consume much electricity, typically featuring power ratings between 1000 and 1800 watts.

But do air fryers live up to their energy efficient claims? We are about to explore this in detail.

What Does It Mean To Be Energy Efficient?

According to experts at Energy Star, energy efficiency means a certain appliance requires less electricity to perform the same functions than a less power-efficient unit.

The goal of an energy-efficient appliance is to provide you with the maximum output using the least amount of power and to reduce electricity costs.

In some cases, wastage and inefficiencies can cause household appliances to draw more electricity than they need.

In those situations, these appliances cannot be considered highly efficient.

How To Check The Energy Efficiency Of An Air Fryer

Air Fryers Energy Efficient Than Oven and Other Kitchen Appliances

You can check the energy efficiency by doing simple math involving a few steps.

Start with checking your appliance's wattage; let’s say it is 1400W. Multiply the wattage by the number of hours it is used per day.

Finally, divide the result by 1000.

These calculations yield the per-day kWh of your air fryer.

Energy Consumption (kWh) = (Wattage × Hours Used)/1000

Now, multiply the kWh by the rate at which you acquire electricity from your supplier:

Cost = Energy Consumption (kWh) × Electricity Rate

Factors Making Air Fryers Energy-Efficient

Many factors make using an air fryer more energy-efficient than an oven. We have listed some of them below.

An Air Fryer Cooks Faster

The average cooking time of an air fryer is no more than 30 minutes because of the small cooking space, which heats up pretty fast.

On the contrary, a standard oven has an average capacity of 60 to 70 liters, whereas a gas oven often has more than 100 liters. Therefore, their cooking time is at least 30 minutes or more than an air fryer.

As a result, gas and electric ovens run much longer to cook the same thing an air fryer does much more quickly, leading to higher energy consumption and costs.

Here is a quick overview of the cooking time of an air fryer vs. an oven when making various dishes

Air Fryers Don't Need Preheating

Most air fryers start cooking when you plug them into an electric socket. In cases when preheating air fryer is necessary, an average 3-4 QT air fryer only needs 2-3 minutes to preheat and start cooking.

Conversely, preheating is a must for electric or gas ovens.

An average oven takes around 15-20 minutes to preheat, extending its overall operational time.

Doing the math tells you that using an air fryer is not only a time saver but an energy-efficient choice.

Air Fryers Don’t Waste Heat

Air fryers, unlike ovens, don’t dissipate heat through their body. Hence, heat remains concentrated within the cooking chamber, contributing to faster cooking and less energy consumption.

Air Fryer Vs Electric Oven Vs Gas Electricity Usage And Cost

The electricity usage and cost comparison among an air fryer, electric oven, and gas oven may not be as simple as it might look.

Several factors can influence the costs, such as the electricity costs in your area, the unit's power rating, the appliance's size, etc.

For this reason, we have used averages and estimates to make the comparison practical and acceptable.

Calculating Air Fryer Cost

An air fryer’s power rating can vary depending on its size. Typically, a smaller air fryer consumes less energy than a large dual basket air fryer.

Now, let’s take the example of a standard 4-QT air fryer consuming about 1500 watts of power, 

The average electricity cost in the US is about 23 cents per kWh in 2023. Meanwhile, in the UK, the average per kWh cost of electricity is 34p per kWh.

Using the method of calculating the cost of electricity usage mentioned earlier in the article, here is what we get:

The Cost of Running an Air Fryer for One Hour in the US

1500 watts*1/1000 = 1.5kWh

1.5kWh*23 cents = 34 cents

The Cost of Running an Air Fryer for One Hour in the UK

1500 watts*1/1000 = 1.5kWh  

1.5kWh* 34p = 51 pence

Considering this calculation, if you use your air fryer for one hour daily for a year, your energy cost would be $124 in the US and around £186 in the UK.

Electrical Oven Cost

Electrical Oven Cost

Electric ovens need around 3000 watts of power for their operations, which is half the average power rating of an air fryer.

The exact wattage of your oven can be found on the appliance tag of your oven or instruction booklet.

Using the same calculation as mentioned above.

The Cost of Running an Electric Oven for One Hour in the US

3000 watts*1/1000 = 3kWh

3kWh*23 cents = 69 cents

The Cost of Running an Electric Oven for One Hour in the UK

3000 watts*1/1000 = 3kWh

3kWh*34p = 102 pence

If you use your oven for one hour daily for a year, you will have to pay roughly £379 in the UK and $250 in the US. These costs are approximately double that of using an air fryer for the same duration.

Gas Oven Cost

Gas Oven Cost

To calculate the cost of using a gas oven, you need the energy ratings of your gas oven in Btu and the per therm cost of natural gas in your area.

Below is a step-by-step process for calculating the cost. The average price of natural gas in the US is $2.3 per therm as of July 2023. Meanwhile, in the UK, it is 134.54 pence per therm.

The Cost Of Running A Gas Oven For One Hour In The UK


$2.3*0.18=$0.41 or 41 cents                                                                                 

The Cost Of Running A Gas Oven For One Hour In The UK


134.54p*0.18=24.2 p

If you use your gas oven for one hour daily for a year, you will have to pay $149 in the US and £88 in the UK.

Our Verdict

CountryGas ovenElectric OvenAir fryer
US41 cents                                                                                69 cents                              34 cents
UK24.2 p                 102 pence51 pence    

From the above comparison, air fryers emerge as the most energy-efficient cooking appliance, with the lowest operational costs.

Whereas, electric and gas ovens have higher associated costs. In the case of a gas oven, since you have to run it for much longer than an air fryer, using it becomes more expensive.

How Much Electricity Does An Air Fryer Use

The electricity usage of an air fryer can vary according to the size and model. Typically, air fryers consume between 800 and 2000 watts of power.

Air fryers with less capacity generally require less energy than large air fryers.

A small air fryer with 1 to 2 Quart capacity can draw 800 to 1000 watts of electricity. A medium 3 to 6 QT air fryer can consume from 1200 to 1500 watts.

While a large air fryer with more than 7 QT capacity may require 1600-1800 watts of power.

Factors Impacting Electricity Usage Of An Air Fryer

Here are some factors that can alter the power requirement of an air fryer. Have a look.

Size Impacts Electricity Use

The size of the air fryer is one of the primary variables that estimate the electricity requirement of an air fryer.

For instance, Ninja AF101, with a capacity of 4 quarts, operates at 1550 watts, while Ninja AF161, with 5.5 quarts, requires 1750 watts of power for its operations.

So, as the capacity of a unit increases, so do its electricity requirements.

Air Fryer Functionality/Settings Impact Electricity Use

Unlike the past, today, air fryers come with smart features such as:

  • Wi-Fi integration
  • Shake reminder
  • Multiple cook settings (toast, broil, dehydrate)
  • Large displays that always stays ON

These value-added features also increase the power requirements of an air fryer.

If the display on an air fryer is always ON and the interior light does not turn off until the food is cooked, this appliance generally consumes more electricity.

Hence, buying a multi-functional air fryer might cost you more than a basic air frying unit.

Various Food-Related Factors Impact Electricity Use

These two food-related factors can impact electricity consumption.

  • The amount of food
  • The cooking duration

All of these aspects are interlinked with each other.

Cooking two pounds of fries will take less time than cooking three.

Cooking one chicken breast in an air fryer may take fifteen minutes. In comparison, the cooking time may increase to twenty minutes when you cook two chicken breasts.

The longer the cooking time, the higher the electricity usage.

Air Fryer Brand/Model Affect The Electricity Use

Sometimes, air fryers of the same size, cooking settings, etc., have different power requirements.

Kitcook and Ultrean air fryers have the same capacity, but their power requirements differ.

The former requires 1300 watts of power, while the latter operates at 1500 watts.

It means that power consumption also comes down to the manufacturer and the brand of the air fryer.
