Estimate cooking cost from selected power, daily cooking time and the hob’s average load.
We convert watts to kilowatts and minutes to hours, apply the average-load percentage and then multiply by days and tariff.
A data sheet may show more than 7 kW for the whole hob, but using one zone at medium power draws much less.
Induction reduces transfer losses compared with a radiant resistance, although cookware and cooking habits still matter.
The total connected load of an induction hob may exceed 7 kW because it represents several zones operating together. If you normally cook on one or two zones, using the full connected load can greatly overstate monthly electricity use.
Induction can deliver high power quickly, especially in Boost mode, but a shorter heating time can offset some of that peak demand. The useful quantity is total kWh for the cooking task, not the largest instantaneous wattage.
Use compatible cookware and match the pan base to the active zone. Lids, sensible power settings and switching down once boiling is reached can reduce powered-on time without changing the recipe.

Editorial review: 11 Oct 2026. Total connected load and average cooking consumption are different quantities.
