How many watts does a slow cooker use?
A slow cooker uses 150–350 W (about 250 W on average). Running 4 hours/day, that is about 1.00 kWh a day and 30.0 kWh a month — roughly $5.49 a month at the U.S. average rate of 18.31 ¢/kWh.
This is the slow cooker electricity usage reference: watts, amps on a 120 V circuit, the kWh math, and links to what that usage costs in each state.
Watts, amps, and kWh for a slow cooker
| Measure | Value |
|---|---|
| Rated wattage range | 150–350 W |
| Average draw used in our math | 250 W |
| Amps at 120 V | 1.3–2.9 A (2.1 A at the average draw) |
| kWh per hour | 0.25 kWh |
| kWh per day at 4 hours/day | 1.00 kWh |
| kWh per month | 30.0 kWh |
| Cost per month at the U.S. average (18.31 ¢/kWh) | $5.49 |
The math is kWh = watts × hours ÷ 1000 and amps = watts ÷ volts. A standard 120 V household circuit on a 15 A breaker carries about 1,800 W. For the dollars in your state, open cost to run a slow cooker in Texas and switch states from there.

Frequently asked questions
How many watts does a slow cooker use?
A slow cooker uses 150–350 W (about 250 W on average). Our usage and cost math uses 250 watts running 4 hours/day.
How many amps does a slow cooker draw?
On a 120 V circuit, 150–350 W works out to about 1.3–2.9 A; at the 250 W we use in the math that is 2.1 A.
How much electricity does a slow cooker use per month?
About 30.0 kWh a month at 4 hours/day. Lighter use (2 hours/day) comes to roughly 15.0 kWh and heavier use (6 hours/day) roughly 45.0 kWh.
How much does it cost to run a slow cooker?
About $5.49 a month at the U.S. average rate of 18.31 ¢/kWh — from roughly $3.82 in Louisiana to $14.40 in Hawaii at the same usage. The state cost-to-run pages price it at every state's rate.
