induction hob power consumption calculator

If you are planning to buy a new induction hob or wondering how much electricity your existing induction hob is consuming then this article is for you. In this article, we will calculate the power consumption of an induction hob and also look at how much it costs to use one.

Induction Hobs are normally rated between 1500 watts to 7200 watts. A 2000-watt induction hob running for 1 hour in a day will consume around 2 kWh of electricity in a day. This adds up to around 60 kWh of electricity in a month.

This would roughly translate to a monthly electricity cost of $ 9.72 in the US, £ 16.2 in the UK, C$ 18 in Canada, A$ 20.4 in Australia and Rs 600  in Mumbai, India.

Read the article to know how you can calculate the power consumption of your induction hob using a simple calculator.


Induction Hob power consumption:

The power consumption of an induction hob (for that matter any electrical appliance) depends upon two main things,

  1. First is the wattage of your induction hob,
  2. And second is the electricity tariff in your area.

Before we jump into calculating the power consumption of your induction hob let’s see what these terms are and how you can find out your induction hob’s wattage and the electricity tariff of your locality.

If you already know these terms and just want to use the calculator then please scroll down to use the calculator.

Let’s check out the wattage of different types of induction Hobs.


What is the wattage of An Induction Hob:

Most induction hobs you will find in the market comes between a wattage range of 1500 watts to 7200 watts. Generally, the more the number of induction plates/burners, the higher the wattage.

For example, the induction hob on the left has 2 induction plates/burners one of 1600 watts and the other of 1700 watts, a total of 3300 watts.

Similarly, this induction hob on the right has 4 induction plates/burners each of 1500 watts, a total of 6000 watts.

You can find the wattage of your induction hob by reading the label on it or just look for your induction hob on amazon and you will find its wattage in the description section.

(If you don’t have time to do this, then don’t worry I have put together a table below that shows the power consumption of a range of induction Hob with different wattages.)

If you don’t know what a watt is then here is a quick explanation,

Watt is the unit of power. It means the rate at which electricity is consumed or produced by a device. For example, a 2000-watt Induction hob consumes power at a rate of 2000 watts per hour, it does not mean that the hob consumed 2,000 units of electricity, it means it will consume power at a rate of 2,000 watts every hour.

So, in short, the wattage of an induction hob lies between 1500 watts to 7200 watts and you can find it by looking at the label on it. With that out of the way, let’s look at what is electricity tariff.


What is your Electricity Tariff:

In simple words, electricity tariff is the amount your electricity provider charges you for the usage of one unit (kWh) of electricity. I live in Mumbai, India here the electricity tariff is Rs 12/kWh.

(What is a Kilowatt hour (kWh) Kilowatt hours or units of electricity is the energy consumption of a device. For example, a 50-watt table fan running for 50 hours will consume 50 watts x 50 hours = 2500-watt hours = 2.5-kilowatt hours of electricity = 2.5 units of electricity. (1 kWh of electricity = 1 unit of electricity))

To find your electricity tariff, just look into your previous month’s electricity bill and find out your monthly electricity consumption, then just divide your monthly electricity consumption by your total monthly electricity bill, the figure you get is approximately your electricity tariff.

I have put together the following table that shows the electricity tariff of a few countries.


How To Calculate Induction Hob power consumption:

With these two pieces of information in hand, you are ready to find the power consumption of your induction hob.

Let me show you an example

induction hob power consumption

I have selected this 3500-watt induction hob listed on amazon. It has 2 induction plates/burners one of 1700 watts and the other of 1800 watts.

Let’s assume we will use this induction hob for 3 hours every day for the entire year. (1 hour each for breakfast, lunch, and dinner)

Hence, we will calculate the daily, monthly, and annual power consumption of this 3500 watts induction Hob.

Before we start with the calculation I would like to point out one thing, most induction hobs available in the market have different power-saving mode settings.

Meaning, even though each burner is rated at around 1700 watts you can run each of the burners at different wattages like 1000 watts, 1200 watts, and 1500 watts depending on the food you cook.

There is no need to run the induction hob at full power all the time. This greatly reduces power consumption.

However, for our calculation we are assuming we will be using both the burners at maximum capacity, i.e 3500 watts, hence, the power consumption values will be on the higher side.

With the knowledge of your induction hob and your electricity tariff, just use this simple formula to calculate power consumption.

Power consumption of an appliance = Wattage of the appliance X operational hours

Cost to run an appliance = Power consumption of the appliance X electricity tariff

(Operational hours is basically the number of hours you are using your induction hob)

Now let’s calculate,


How Much Electricity Does an Induction Hob Consume:

In our case, wattage is 3500 watts and operational hours are 3 a day, 90 a month, and 1,095 a year.

Hence by using the above formula,

  • Daily Power consumption of 3,500 watts induction Hob (3 hours) = 3500 watts X 3 hours = 10.5 kWh
  • Similarly, the monthly power consumption of 3500 watts induction Hob (3 hours/day @ 30 days) = 3500 watts X 3 X 30 = 315 kWh
  • And the annual power consumption of 3500 watts induction Hob (3 hours/day @ 365 days) = 3500 watts X 3 X 365 = 3,832 kWh

Now that we know the power consumption of our induction hob let’s multiply it by our electricity tariff to calculate how much it will cost to run this 3500-watt induction hob.

For your reference, I have calculated the cost to run this 3500-watt induction hob for 3 hours every day for an entire month in the US, UK, Canada, Australia, and Mumbai, India.

  • In the US, the avg. electricity tariff is around 16.20 cents per kWh, hence it will cost around $ 51.03 (315 kWh X 16.20 cents) to run this 3.5 kW induction hob for 3 hours every day for an entire month in the US.
  • In the UK, the avg. electricity tariff is around 36 pence per kWh, hence it will cost around £ 85.05 (315 kWh X 36p/kWh) to run this 3.5 kW induction hob for 3 hours for an entire month in the UK.
  • In Canada, the avg. electricity tariff is around C$ 0.156 per kWh, hence it will cost around C$ 49.14 (315 kWh X C$ 0.156/kWh) to run this 3.5 kW induction hob for 3 hours for an entire month in Canada.
  • In Australia, the avg. electricity tariff is around A$ 0.32 per kWh, hence it will cost around A$ 100.8 (315 kWh X C$ 0.32/kWh) to run this 3.5 kW induction hob for 3 hours for an entire month in Australia.
  • In Mumbai, India, the avg. electricity tariff is around Rs 10 per kWh, hence it will cost around Rs 3,150 (315 kWh X Rs 10/kWh) to run this 3.5 kW induction hob for 3 hours for an entire month in Mumbai, India.

How much does it cost to run an induction Hob:

For your reference, I have calculated the cost to run this 3.5 kW induction Hob for 3 hours daily throughout the entire year in the USA, UK, Canada, Australia, and Mumbai, India.

Country (Tariff)Daily Power Consumption of Induction Hob
(3.5 kW @ 3 hours)
Monthly Power Consumption of 3.5 kW Induction Hob
(3.5 kW @ 90 hours)
Annual Power Consumption of a 3.5 kW Induction Hob
(3.5 kW @ 1,095 hours)
USA (16.20 c/kWh)10.5 kWh, $ 1.701315 kWh, $ 51.033832 kWh, $ 620.56
UK (36p/kWh)10.5 kWh, £ 2.83315 kWh, £ 85.053832 kWh, £ 1,034.29
Canada (C$ 0.156/kWh)10.5 kWh, C$ 1.63315 kWh, C$ 49.143832 kWh, C$ 597.47
Australia (A$ 0.32/kWh)10.5 kWh, A$ 3.36315 kWh, A$ 100.83832 kWh, A$ 1,226.72
Mumbai, India (Rs 10/kWh)10.5 kWh, Rs 105315 kWh, Rs 3,1503832 kWh, Rs 38,320

If your country is not on the table, then just note down the power consumption and multiply your electricity tariff to get the running cost.

NOTE: -The above figures show the maximum power consumption of a 3500-Watt induction Hob, however, the actual power consumption will greatly depend on the power rating and temp setting of each burner, the number of burners used, and operational hours.

Hence, if you are using just one induction plate/burner then divide the above figures by 2.


Electricity Consumption of Different Wattage Induction Hob:

For your reference, I have made the below table that shows the power consumption of a range of induction hobs having different wattages. I have assumed 1 hour of daily operation for an entire year.

Induction Hob WattageDaily Power Consumption
(1 Hour)
Monthly Power Consumption (30 Hours)Annual Power Consumption (365 Hours)
1.5 kW1.5 kWh45 kWh547 kWh
2 kW2 kWh60 kWh730 kWh
3.2 kW3.2 kWh96 kWh1168 kWh
6.4 kW6.4 kWh192 kWh2336 kWh

Induction Hob Power Consumption Calculator:

As I said before the above-calculated values show the maximum power consumption of an induction hob, however, the actual power consumption will be 10% to 40% lower than it.

If you are not happy with the approximate results and you want to know the exact power consumption, then I would suggest you buy a cheap Kill-A-Watt Meter from amazon.


Calculate The Exact Power Consumption Of Any Induction Hob Using Kill A Watt Meter:

Kill A Watt Meter is a simple device that gives real-time data on the power consumption of any device.

You can check it on amazon using this link – Kill A Watt Electricity Usage Monitor

To use a kill-a-watt meter to calculate the power consumption of your induction hob, first, connect your induction hob plug into the kill-a-watt meter and then plug the kill-a-watt meter in your wall socket and you are good to go.

Then start using your induction hob and you can see in real-time how many kWh (units) of electricity it is consuming.


Do induction hobs consume a lot of electricity:

To conclude this article, Yes, an induction hob consumes a lot of electricity.

To give you some comparison a 65-inch LCD TV is rated at 120 watts and it takes 8-9 hours of operation to consume 1 kWh of electricity, whereas, a 2000-watt induction hob can consume 1 kWh of electricity in just 30 – 40 minutes.
