May 30, 2024###### How much does it cost to run a portable induction hob?

May 30, 2024Getting straight to the point, it costs approximately **£0.24** to run **a microwave** for one hour. This depends on how much you pay for your energy and the wattage of your microwave however, so this is just an estimate.

To get a more accurate cost of how much it costs to run your microwave for different lengths of time, you can use our simple calculator below**.**

## Energy usage calculator for your microwave

To find how much electricity your microwave uses, you will need to know its power consumption and the unit price you pay for your electricity.

We have prefilled the power consumption with the average for a microwave and have used the current unit price based on the **June 2024** price cap. This will give you a quick idea of the cost, but you should use your details for more accurate figures.

You then need to enter your hourly usage time daily, and we’ll show you the cost per day, month, and year to run your microwave.

## How to use our calculator?

Here are some quick steps on how to use our calculator:

#### Identify the power usage of your microwave

First, find out your microwave’s power usage. The appliance label or user manual usually indicates this in watts (W). If you can’t find it, you can look up the** average wattage for a microwave, which is 1000.**

#### Work out how often you use your microwave

Next, estimate how often you use themicrowave. Record the number of hours per day or the total time per week you use it. This will help determine the overall energy consumption.

#### How much your electricity costs

Check your electricity bill or contact your energy provider for the cost per kilowatt-hour (kWh) for your electricity. You’ll use this rate to calculate the cost of running your microwave.

#### We’ll tell you how much it costs to run your appliance

Enter the power usage, usage duration, and electricity cost into the calculator. The calculator will process this information and provide you with an estimate of how much it costs to run your microwave. You can see these costs per day, per month and per year.

## How to calculate the energy cost of your microwave manually

To manually work out the cost of your microwave (or any appliance), you need to do the following:

**Convert the power rating to kilowatts (kW)**: Power (kW) = Wattage (W) / 1000**Calculate the energy consumed (in kWh)**: Energy (kWh) = Power (kW) × Time (hours)**Calculate the cost**: Cost (£)= Energy (kWh) × Cost per kWh (£/kWh)

You first need to divide the wattage of the appliance by 1,000. This converts the wattage to Kilowatts.

Next, calculate the energy consumed in Kilowatt hours (kWh) by multiplying the Kilowatts by the number of hours of usage.

Finally, multiply the kWh by the unit price of electricity.

**An example for a microwave would be: 1 kW x 5 hours x 0.24p = £1.20. **

This would be the cost to run the microwave for five hours when the unit price of electricity is 24p.

## How many watts does a microwave use?

Based on data from sources like Energy Saving Trust and National Energy Action, we’ve found that the wattage for the average microwave is: **1000 watts**.

## Factors that impact the running costs of a microwave

The energy running costs of using a microwave depend on several factors.

The wattage of the microwave plays a significant role. Higher wattage microwaves use more energy but cook food faster.

How often you use the microwave also affects the costs. Frequent use will naturally lead to higher energy consumption.

The duration of each use is another factor. Longer cooking times mean more energy is used.

The efficiency of the microwave can impact costs as well. Newer models tend to be more energy-efficient.

Finally, the electricity tariff you are on will influence the overall running costs. Different tariffs can make a noticeable difference in your energy bill.

## How to save money on running your microwave

Using a microwave efficiently can help you save money on your energy bills.

Firstly, make sure to use microwave-safe containers that allow heat to pass through easily, as this will cook your food more quickly and use less energy.

Additionally, try to cook in bulk when possible, as heating multiple portions at once is more energy-efficient than cooking single servings repeatedly.

It’s also a good idea to defrost food in the fridge overnight rather than using the microwave’s defrost setting, which consumes more power.

Keeping the microwave clean is essential too, as food splatters can absorb energy and make the appliance work harder.

Finally, consider using the microwave for smaller cooking tasks instead of the oven, as it generally uses less energy and can be more cost-effective for quick meals.

## Average runnings costs by different time periods

Time | Usage (kWh) | Cost (£) |
---|---|---|

Per Day (4 hours per day) | 4 | £0.96 |

Per Month (30 days per month) | 120 | £29 |

Per Year (365 days per year) | 1460 | £350 |

## Frequently Asked Questions

Below, we have answered a few questions related to microwave energy usage.

### Does a microwave use a lot of electricity?

A microwave does not use a lot of electricity compared to other kitchen appliances.

It is designed to heat food quickly, so it only runs for a short time.

This makes it more energy-efficient than an oven or stove.

### Are microwaves energy efficient?

To know if a microwave is energy efficient, you need to look at its power consumption. Microwaves with lower wattage use less electricity, making them more energy efficient.

Additionally, newer models often have better technology that uses energy more effectively. If the microwave has an eco-mode or energy-saving features, it is likely to be more efficient.

### How much energy does the average microwave use?

Again, based on available data from sources like Energy Saving Trust and National Energy Action, we’ve found that the average microwave uses approximately 1 kWh energy when switched on for one hour.

### How much does it cost to run a microwave for 1 hour?

Based on the average wattage of a microwave being 1000, we can work out that the average microwave costs **£0.24 to run for one hour**.

We have used the current electric unit price 24p from the June 2024 to work this out.

### How much does it cost to run a microwave per day?

Using the current average electric unit price of 24p from the June 2024 price cap and the average wattage of a microwave’s being 1000, we can work out that the average microwave costs **£0.96 to run for one day**.

We’ve assumed it will be used for 4 hours per day.

### How much does it cost to run a microwave per year?

The average wattage of a microwave is 1000 and the current average unit price of electricity based on the June 2024 is 24p. Using this, we can work out that the average microwave costs **£350 to run per year**.

We’ve assumed it will be used for 365 days per year.
