Annual electricity cost of running a fridge.

Calculate the annual electricity cost of running a refrigerator based on kWh/year rating and your electricity rate. Free and runs in your browser.

What this tool does

Enter the fridge's annual kWh rating and your electricity rate per kWh. The tool shows annual and 10-year running cost.

A standard fridge uses 350-500 kWh per year. At 0.30/kWh that is 105-150 annually. Over 10 years, 1,500. An A-rated efficient model at 200 kWh saves roughly 90/year vs an older one — enough to pay for itself in 5 years on the premium. Running cost is often ignored when buying a fridge and is the larger number over the machine's life.

Run it with sensible defaults

Using annual consumption of 350, electricity rate per kwh of 0.3, the calculation works out to 105.00. Nudge the inputs toward your own situation and the output recalculates instantly. The defaults are meant as a starting point, not a recommendation.

The levers in this calculation

The inputs — Annual Consumption (kWh) and Electricity Rate per kWh — do not pull with equal force. Frequency and unit price pull the total in different directions. The biggest surprise for most people is how small recurring amounts compound into large annual figures — that's where this calculation earns its keep.

How the math works

Direct multiplication. Real usage can vary 10-20% based on ambient temperature, door openings, and age. The working is transparent — you can verify every step yourself in the formula section below. No black box, no opaque "proprietary model".

Why run the calculation

Utility bills creep. Small annual increases stack into meaningful differences over a decade. Running this once a year and switching providers when the gap widens is one of the easiest ways to keep household costs in check.

What this doesn't capture

Usage varies month-to-month; tariffs change; discounts come and go. The figure here is a clean baseline — your actual annual bill will fluctuate around it. Use the calculation to benchmark providers, not as a prediction of a specific bill.

Example Scenario

Fridge running cost produces an annual figure based on the inputs provided.

Inputs

Annual Consumption (kWh):350
Electricity Rate per kWh:0.3 £
Expected Result£105.00

This example uses typical values for illustration. Adjust the inputs above to match a specific situation and see how the result changes.

Frequently Asked Questions

Where is the kWh/year on the label?
Bottom half of the energy label, typically shown as 'XXX kWh/annum' alongside the A-G rating.
Is energy rating worth paying for?
For a fridge that runs 24/7 for 10+ years, yes. A cheap inefficient fridge usually costs more over its life than a more expensive efficient one.
What about freezer?
Combined fridge-freezers use more kWh. Standalone freezers vary hugely — chest freezers are typically most efficient, upright frost-free least.
How accurate is the kWh/year figure?
Measured under standardised lab conditions. Real-world usage is often 10-15% higher in warm homes or where the fridge is well-stocked and opened often.
