Air Fryer Running Costs: Are They Cheaper Than an Oven?
A big reason for the air fryer boom is the promise of lower running costs than an oven. Here's the honest picture of what an air fryer costs to run and when it really saves money.
Why they can be cheaper
An air fryer heats a much smaller space than a full-size oven and reaches temperature faster, so for small and medium portions it uses less energy to cook the same food. Cooking times are often shorter too. For a portion of chips or a couple of chicken breasts, that adds up to a meaningful saving over firing up a large oven.
When the saving shrinks
If you're cooking a big meal that fills a full-size oven anyway - a large roast with several trays - the oven may be just as efficient, because you're using all that space. The actual cost depends on the air fryer's wattage, how long it runs, and your electricity tariff, so check the stated power rating rather than assuming a fixed figure.
