How we work it out
Cost per hour = watts ÷ 1,000 × share of time at full power × price per kWh. For a 1,800W electric hob (one ring) at 60%: 1,800 ÷ 1,000 × 0.6 × 26.32p = 28p. A thermostat switches the element on and off, so it doesn't draw full power the whole time. The 60% figure is our assumption. It depends on the room, the weather and the thermostat setting, so change it in the calculator if you know better.
