an hour, to the nearest penny
| A day | 3.9p |
|---|---|
| A week | 27.6p |
| A month | £1.20 |
| A year | £14.41 |
| Electricity used in a year | 55 kWh |
That is 2% of the 2,500 kWh a typical home uses in a year.
A freezer switches itself off once it reaches temperature, so it draws this power only part of the time. Treat this as the most it could cost.

| Step | Sum | Answer |
|---|---|---|
| Turn watts into kilowatts | 150 W ÷ 1,000 | 0.15 kW |
| Cost of one hour | 0.15 kWh × 26.32p per kWh | 3.9p |
| Cost of one day's use | 3.9p × 1 hours | 3.9p |
| Cost of one week | 3.9p × 7 days | 27.6p |
| Cost of one year | 27.6p ÷ 7 × 365 days | £14.41 |
What this leaves out or assumes
- The standing charge is left out, because you pay it whether or not you use this appliance.
- A month is one twelfth of a year.
- The appliance draws its full power for the whole time it is on.

A freezer does not draw 150 watts all the time. It switches itself off once it reaches temperature and back on when it needs to. The figures on this page are for the time it is actually drawing power, so they are the most it could cost. You cannot get a day's cost by multiplying the hourly figure by 24.
If your freezer has an energy label or a manual that gives its electricity use in kWh, use that instead: multiply the kWh by 26.32p to get the cost.
Cost while it is drawing power
| Running for | Electricity used | Cost |
|---|---|---|
| 5 minutes | 0.012 kWh | 0.3p |
| 10 minutes | 0.025 kWh | 0.7p |
| 30 minutes | 0.075 kWh | 2p |
| 1 hour | 0.15 kWh | 3.9p |
| 2 hours | 0.3 kWh | 7.9p |
| 4 hours | 0.6 kWh | 15.8p |
Cost over a month and a year
If it drew full power for this long every day:
| Drawing power for | A month | A year |
|---|---|---|
| 30 minutes a day | 60p | £7.21 |
| 1 hour a day | £1.20 | £14.41 |
| 2 hours a day | £2.40 | £28.82 |
| 4 hours a day | £4.80 | £57.64 |
How much electricity does a freezer use?
