A typical slow cooker (200 W) costs C$0.030 per hour, or about C$7.18 per month at 8 hours a day in Ontario. Average running cost
| Wattage | Per hour | Per day | Per month | Per year |

Each C$1.00 of electricity buys roughly 33.4 hours of use.
How to lower the cost of running a slow cooker
- Use the low setting for long cooks. High draws more and finishes sooner but uses similar total energy.
- Keep the lid on. Every peek adds 15 to 20 minutes of cooking.
- Fill it at least half full for efficient heat transfer.
