Formula
air fryer wattage ÷ 1,000 × cooking time × electricity price = running cost
For example, a 1,500W air fryer used for 0.5 hours at 24.67p/kWh costs 1.5 x 0.5 x 24.67p = 18.50p.
Ways to reduce the cost
- Avoid long preheats unless the recipe needs one.
- Cook suitable portions rather than using a full oven for small meals.
- Do not overcrowd the basket if it extends cooking time.
- Batch-cook similar items when practical.
