How much electricity does a mini fridge use?
With mini fridges potentially running 24/7 in your home or office, a common question when purchasing one is how much electricity it will use. Luckily, it’s fairly straightforward to find out the electricity usage as it will be included on the data plate on the back of the appliance. If you can’t find this information, visit Label 2020, an EU energy label initiative and database, to search for your appliance there.
How much does it cost to run a mini fridge?
So you’ve figured out how much electricity your mini fridge uses, but how much extra is that likely to cost you?
According to Ofgem, an independent National Regulatory Authority in the UK, the current average cost of electricity for households currently stands at £0.28 per kWh used (as of July 2022). This is in addition to the daily standing charge of £0.45, a daily fixed amount that households must pay to their energy provider irrespective of how much energy is used.
To calculate how much an appliance in your home will therefore cost, follow the following instructions:
- Multiply the appliance’s wattage (supplied by the manufacturer) by the number of hours you plan to use it per day. This will leave you with the number of watt-hours consumed each day.
- Divide that number by 1000 to find out the appliance’s kilowatt hours (kWh), which is how electricity usage is measured on your electricity bill.
- Multiply the kWh by 30 to find out the kWh per month.
- Finally, multiply the kWh per month by how much you pay per kWh to find out how much it will likely cost you each month. This will be on your electricity bill, but if you can’t find it, use the UK average mentioned above (£0.28 per kWh).
So, for example, if a mini fridge has a wattage of 100, multiplied by 24 hours will mean the appliance consumes 2,400 watts each day. Divided by 1000, the appliance’s kWh would be 24. Multiplying that number by 30 (days) will give you a kWh per month of 816. Multiply this by £0.28, and the average monthly cost of running the mini fridge all day would be roughly £2.28.
You can also calculate this by visiting Label 2020 and use their calculator to work out your appliance’s efficiency and estimated running cost.
