Slow cookers use little power for a long time. An 8 hour cook on low uses about 1 kWh, comparable to running an oven for 40 minutes.
A typical slow cooker (200 W) costs £0.052 per hour, or about £12.48 per month at 8 hours a day in United Kingdom. Average running cost
| Wattage | Per hour | Per day | Per month | Per year |
|---|---|---|---|---|
| Low (100 W) | £0.026 | £0.21 | £6.24 | £75.92 |
| Typical (200 W) | £0.052 | £0.42 | £12.48 | £151.84 |
| High (300 W) | £0.078 | £0.62 | £18.72 | £227.76 |
Formula: watts ÷ 1000 × hours × price per kWh. Typical use is 8 h/day ≈ 584 kWh per year.

How to lower the cost of running a slow cooker
