**Electric Rice Cooker Power Consumption:**

The power consumption of an electric rice cooker (for that matter any electrical appliances) depends upon two main things

- First is the wattage of your rice cooker,
- And second is the electricity tariff in your area.

Before we jump in to calculating the power consumption of your electric rice cooker, lets see what these terms are and how you can find your electric rice cooker 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.

**What is the Wattage of an Electric Rice Cooker:**

The **wattage of a rice cooker** **varies from 300 watts to 1000 watts, generally larger the cooking volume, higher is the wattage.**

You can **find the wattage of your rice cooker by reading the label on it or just look for your rice cooker 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 at the end which shows power consumption of a range of rice cooker with different wattages.)

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 an electric rice cooker lies between 30 watts to 1000 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 Electric Rice Cooker Power Consumption:**

With these two information in hand you are ready to find the power consumption of your rice cooker.

Let me show you with an example,

**I have selected a 700 watts rice cooker listed on amazon.** Lets assume we will be using it for 30 minutes daily for an entire year.

Hence, we will calculate the power consumption of this 700 watt rice cooker in a day, in a month and in an entire year.

With the knowledge of your rice cooker wattage and your electricity tariff, just use this simple formula to calculate power consumption.

**Power consumption of a rice cooker = Wattage of a rice cooker X operational hours**

**Cost to run a rice cooker = Power consumption of a rice cooker X electricity tariff.**

(Operational hours is basically the number of hours you are using your rice cooker)

Now let’s calculate

**Electricity consumption of A 700 watt Electric Rice Cooker:**

In our case, wattage is 700 watts and operational hours is 30 minutes (0.5 hours) in a day, 15 hours in a month and 182 hours in a year.

Hence by using the above formula.

**Power consumption of a 700 watt rice cooker in a day (30 minutes) = 700 watt X 0.5 hours = 350 watt hours (Wh) = 0.35 kWh**

We will convert this 350 watt hour (Wh) into Kilo watt hour (kWh) as electricity tariffs are given for per kWh. To do this simply divide 350 by 1000, you will get 0.35 kWh (As 1kg = 1000g, 1km = 1000m, similarly 1kWh = 1000Wh)

**Similarly, Power consumption of a 700 watt rice cooker in a month (0.5hrs/day x 30days) = 700 W X 15 = 10.50 kWh**

**And Power consumption of 700 watt rice cooker in a year (0.5hrs/day @ 365 days) = 700 W X 182 = 127.40 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 use your rice cooker.

let’s calculate how much it will cost to run this 700 watt electric rice cooker for 30 minutes daily 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 $ 2.70 (10.50 kWh X 25.8 cents) to run this 700 watts rice cooker for 30 minutes daily for an entire month.****In case of London, the electricity tariff in London is around 36p/kWh , hence it will cost around £ 3.78 (10.50 kWh X 36p/kWh) to****run this****700 watts rice cooker for 30 minutes daily for an entire month.****In case of Mumbai, the electricity tariff in Mumbai is around Rs 10 per kilowatt hour (kWh), hence it will cost around Rs 105 (10.50 kWh X Rs 10) to****run this****700 watts rice cooker for 30 minutes daily for an entire month.**

For your reference I have calculated the cost to run this 700 watts electric rice cooker for 30 minutes daily throughout the entire year in Los Angeles, London and Mumbai.

Country (Tariff) | Daily Power Consumption of an Electric Rice Cooker)(700 Watt @ 30 min | Monthly Power Consumption of an Electric Rice Cooker(700 Watt @ 15 hours) | Annual Power Consumption of an Electric Rice Cooker(700 Watt @ 182 hours) |
---|---|---|---|

Los Angeles (25.8 c/kWh) | 0.35 kWh, cents 9 | 10.50 kWh, $ 2.71 | 127.40 kWh, $ 32.87 |

London (36p/kWh) | 0.35 kWh, pence 12.60 | 10.50 kWh, £ 3.78 | 127.40 kWh, £ 45.86 |

Mumbai (Rs 10/kWh) | 0.35 kWh, Rs 3.5 | 10.50 kWh, Rs 105 | 127.40 kWh, Rs 1,274 |

**The above figures suggest the maximum power consumption of a 700 watt rice cooker, the actual power consumption can be 5 to 10 % less.**

**Also the above power consumption is for “cooking mode”, if you are using the “keep warm mode” then the power consumption would be negligible, close to 1/10th of the above values.**

**Electricity consumption for different Wattage electric Rice Cooker**:

For your reference, I have made the below table which shows the power consumption of a range of electric rice cookers having different wattages. I have assumed 30 minutes operation everyday for an entire month.

Wattage | Daily Power Consumption (30 minutes) | Monthly Power Consumption (30 min x 30 days = 15 hours) | Annual Power Consumption(30 min X 365 days = 182 hours) |
---|---|---|---|

300 watts | 0.15 kWh | 4.50 kWh | 54.60 kWh |

500 watts | 0.25 kWh | 7.50 kWh | 91 kWh |

700 watts | 0.35 kWh | 10.50 kWh | 127.40 kWh |

850 watts | 0.42 kWh | 12.60 kWh | 154.70 kWh |

1000 watts | 0.50 kWh | 15 kWh | 182 kWh |

**As you can see from the above table, a 1000 watt electric rice cooker running for 30 minutes daily will consume around 182 KWh of electricity in a year.**

**This means, it will cost around $ 46.96 (182 X 25.8 cents) in Los Angeles, £ 65.52 (182 X 36 pence) in London, and Rs 1,820 (182 X Rs 10) in Mumbai to use this 1000 watt electric rice cooker for 30 minutes daily for an entire year.**

Now go ahead and use the below calculator to find out the power consumption of your rice cooker.

Just type the wattage of your rice cooker, daily operational hours and your electricity tariff and let the calculator do the math for you.

**Rice Cooker power consumption calculator:**

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