How Much Does It Cost to Run an Induction Cooktop?

About 9 cents a day on the default of 30 minutes of cooking. An 1,800 W burner at a 60 percent duty cycle uses 1.8 x 0.5 x 0.6 = 0.54 kWh, and 0.54 x $0.173 is $0.093.

About 31 cents for an hour at full power, since 1.8 kWh x $0.173 = $0.31. With normal cooking that mixes boiling and simmering at a 60 percent average, an hour costs about 19 cents.

About $2.80 a month: 0.54 kWh x 30 = 16.2 kWh, and 16.2 x $0.173 is $2.80. Over a year that is about 197 kWh, roughly $34.

Up to 1,800 W for a plug-in single burner on 120 V, often adjustable down to 100 to 300 W. A built-in induction range uses 1,200 to 3,700 W per zone and 7,000 to 11,000 W across all zones, on a 240 V circuit.

It draws a lot while on, about 15 A at full power, but cooks quickly. At 30 minutes a day it uses about 197 kWh a year, about $34, and it uses less than a coil or radiant burner for the same food.

Yes, by about 10 to 15 percent. Induction gets about 85 percent of its energy into the food and a coil or radiant burner about 75 percent. On the default use that is roughly 20 to 30 kWh a year, about $3.50 to $5.

It depends on your rates. Induction delivers about 85 percent of its energy to the food and gas about 32 percent, so induction needs about 0.4 units of energy for every 1 unit a gas burner uses. Whether that is cheaper comes down to your price per kWh against your price per therm.

About 2 cents for 1 liter. Heating 1 liter from tap temperature to a boil takes about 0.1 kWh in the water, about 0.12 kWh from the wall at 85 percent efficiency, and 0.12 x $0.173 is about 2 cents.

Only one with an inverter rated at least 1,800 W, or the burner turned down to the station's limit. At the default of 0.54 kWh a day, a 1 kWh station covers about a day and a half of cooking after inverter losses.

Use a lid, match the pan to the burner, and turn it down the moment the pot boils. Cutting 10 minutes of full-power time saves 0.3 kWh, about 5 cents.
