How to use the usage range

The cards above show how the same defined cooking comparison changes as weekly use rises. The important point is not the exact annual saving in any one card: it is that frequency multiplies a relatively small per-cook energy difference. A household using an air fryer once a week will see a very different annual effect from one replacing several oven sessions every week.

Real results depend on food quantity, pre-heating, cooking time and the power actually drawn by each appliance. A full oven cooking several dishes at once can be efficient per portion, while a small air fryer can be efficient for a single tray or small meal. Treat the range as a sensitivity check, then edit the calculator with the cooking pattern you actually expect to use.

What to compare fairly

Compare the same meal or cooking task, not only the appliance wattage. Enter realistic run times for both appliances and use your own electricity unit rate. If the oven would be used anyway for other food, allocating its whole energy use to one item can overstate the benefit of switching.
