How Much Does It Cost to Run a Slow Cooker?
A slow cooker runs all day but only at about 200 watts — a full 8-hour braise uses less energy than one hour of an electric oven. At the US-average rate of 16.5¢/kWh, running a slow cooker costs about $6.02/month ($72.18/year) at typical use. Adjust the watts, hours, and your rate below for your exact number.

Cost = power (kW) × hours × days × your rate. Defaults are typical values — enter your appliance's actual watts (often on a label) and your real rate for a precise figure.
How much electricity does a slow cooker use?
At 200 W for 6 hours a day, a slow cooker uses about 1.2 kWh per day — roughly 37 kWh per month and 438 kWh per year. That's about 4% of the 863 kWh the average US home uses in a month. Energy use is the same everywhere — only the price per kWh changes your bill.

Measure what a slow cooker really costs you
The estimate above uses typical wattage and hours. A plug-in energy meter logs the kilowatt-hours this appliance actually uses — leave it in for a week, multiply by your rate, and the estimate becomes a measurement. A whole-home monitor does the same for every circuit at once, but its sensors install inside the panel.
