If you are wondering how much electricity your waffle maker is consuming then this article is for you. We will calculate the power consumption of a waffle maker and also look at the cost to use it.
By the end of this article you will learn to calculate power consumption of any waffle maker using a simple calculator.
Waffle makers / Waffle irons are normally rated between 700 watts to 1400 watts. A 800 watt waffle maker running for 10 minutes every day will consume around 4 kWh of electricity in a month which adds upto 48.60 kWh of electricity in a year.
The above power consumption figures are same whether you live in India, US, UK or anywhere else. To calculate the cost to run your waffle maker just multiply the power consumption with your electricity tariff.
Waffle Maker Power Consumption:
The power consumption of a waffle maker (for that matter any electrical appliances) depends upon two main things
- First is the wattage of your waffle maker,
- And second is the electricity tariff in your area.
Before we jump in to calculating the power consumption of your waffle maker, lets see what these terms are and how you can find your waffle maker 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.
What is The Wattage of A waffle maker:
A waffle maker wattage varies from 700 watts to 1400 watts, generally the higher the wattage, larger is the heating space and higher is the electricity consumption.
You can find the wattage of your waffle maker by reading on the label underneath it or just look for your waffle maker on amazon and you will find its wattage in the description section.
(if you don’t want to do this then don’t worry, I have put together a table at the end which shows power consumption of a range of waffle makers with different wattage.)
If you don’t know what a watt is then here it is,
Watt is the unit of power. It means the rate at which electricity is consumed or produced by a device.
For example, a 50 watt TV consumes power at a rate of 50 watts per hour, it does not mean that the TV consumed 50 units of electricity, it means it will consume power at a rate of 50 watts every hour.
So in short, the wattage of a waffle maker lies between 700 watts to 1400 watts and you can find it by looking at the label on it. With that out of the way lets 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 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 watt 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 electricity bill and find out your monthly electricity consumption. Then just divide your monthly electricity consumption with your total monthly electricity bill, the figure you get is approximately your electricity tariff.
If you don’t want to do any of this then just google electricity tariff followed by your location.
Calculate Waffle Maker Power Consumption:
With these two information in hand you are ready to calculate the power consumption of your waffle maker.
Let me show you with an example,
I have selected a 800 watts waffle maker listed on amazon. Let us assume we will be using this for 10 minutes everyday for an entire year.
Hence, we will calculate the power consumption of this waffle maker in a day, in a month and in an entire year.
With the knowledge of your waffle maker wattage and your electricity tariff, just use this simple formula to calculate power consumption.
Power consumption of a waffle maker = Wattage of a waffle maker X operational hours
Cost to run a waffle maker = Power consumption of a waffle maker X electricity tariff.
(Operational hours is basically the number of hours you are using your waffle maker)
Now let’s calculate
Electricity consumption of A 800 watt waffle maker:
In our case, wattage is 800 watt and operational hours is 10 minutes in a day, 300 minutes in a month and 3,650 minutes in a year.
Lets first convert the minutes into hour,
10 minutes is equal to 0.1667 hours(10/60), 300 minutes is equal to 5 hours (300/60), and 3,650 minutes is equal to 60.83 hours (3,650/60).
Hence by using the above formula.
Power consumption of a 800 watt waffle maker in a day (10 minutes) = 800 watt X 0.167 hour = 133.33 watt hour (Wh) = 0.133 kWh
We will convert this 133.33 watt hour (Wh) into Kilo watt hour (kWh) as electricity tariffs are given for per kWh. To do this simply divide 133.33 by 1000, you will get 0.133 kWh (As 1kg = 1000g, 1km = 1000m, similarly 1kWh = 1000Wh)
Similarly, Power consumption of a 800 watt waffle maker in a month (5 hours) = 800 W X 5 = 4 kWh
And power consumption of a 1500 watt waffle maker in a year (60.83 hours) = 800 W X 60.83 = 48.66 kWh
Now that we know the power consumption, just multiply it by your electricity tariff and you will get how much it will cost you to run your waffle maker.
let’s calculate how much it will cost to run this 800 watt waffle maker for an entire month in Los Angeles, London and in Mumbai.
- In case of Los Angeles, the electricity tariff in Los Angeles is around 25.8 cents per kilowatt hour (kWh), hence it will cost around $ 1.03 (4 kWh X 25.8 cents) to run this 800 watt waffle maker for 10 minutes everyday throughout the month.
- In case of London, the electricity tariff in London is around 36p/kWh , hence it will cost around £ 1.44 (4 kWh X 36p/kWh) to run this 800 watt waffle maker for 10 minutes everyday throughout the month.
- In case of Mumbai, the electricity tariff in Mumbai is around Rs 10 per kilowatt hour (kWh), hence it will cost around Rs 40 (4 kWh X Rs 10) to run this 800 watt waffle maker for 10 minutes everyday throughout the month.
For your reference, I have calculated the cost to run this 800 watt waffle maker for 10 minutes everyday for the entire month and the entire year in Los Angeles, London and Mumbai.
| Country (Tariff) | Daily Power Consumption of a Waffle Maker (800 Watt @ 10 minutes/day) | Monthly Power Consumption of a Waffle Maker (800 Watt @ 300 min /month) | Annual Power Consumption of a Waffle Maker (800 Watt @ 3,650 min/year) |
|---|---|---|---|
| Los Angeles (25.8 c/kWh) | 0.133 kWh, cents 3.44 | 4 kWh, $ 1.04 | 48.67 kWh, $ 12.56 |
| London (36p/kWh) | 0.133 kWh, pence 4.80 | 4 kWh, £ 1.44 | 48.67 kWh, £ 17.52 |
| Mumbai (Rs 10/kWh) | 0.133 kWh, Rs 1.33 | 4 kWh, Rs 40 | 48.67 kWh, Rs 486 |
From the above results, the annual cost to run a 800 watt waffle heater everyday for 10 minutes for an entire year is $12.56 in Los Angeles, £ 17.52 in London and Rs 486 in Mumbai.
Hence, It’s safe to say waffle iron does not have high power consumption (as we mostly use it for short time, if we are using it 1 hour daily then the story is different).
Electricity Consumption Table For Different Wattage Waffle Maker:
For your reference, I have made the below table which shows the power consumption of different wattage waffle makers running for 10 minutes every day for an entire year.
| Wattage | Daily Power Consumption ( 10 min/day) | Monthly Power Consumption (300 min /month) | Annual Power Consumption (3,650 min/year) |
|---|---|---|---|
| 800 watts | 0.133 kWh | 4 kWh | 48.67 kWh |
| 1000 watts | 0.166 kWh | 5 kWh | 60.83 kWh |
| 1200 watts | 0.20 kWh | 6 kWh | 73 kWh |
| 1400 watts | 0.233 kWh | 7 kWh | 85.17 kWh |
As you can see from the above table, if we use a 1400 watts waffle maker for 10 minutes every day throughout the year, the total power consumption is around 85.17 kWh.
This mean in Los Angeles it will cost $ 21.97 (85.17 kWh X cents 25.8/ kWh), in London it will cost £ 30.66 (85.17 kWh X pence 36/ kWh), and in Mumbai it will cost Rs 851 (85.17 kWh X Rs 10/ kWh) to run this 1400 watts waffle maker for 10 minutes everyday for the entire year.
Now go ahead and use the below calculator to find out the power consumption of your waffle maker.
Just type the wattage of your waffle maker, number of hours of usage and your electricity tariff and let the calculator do the math for you.
