Why the cost differs in Oklahoma
Oklahoma has the 3rd cheapest residential electricity of the 51 US states and territories we track, at 13.38¢ per kWh against a national average of 18.44¢. That is -27.4% compared with the national figure. Oklahoma is a major wind producer with cheap in-state natural gas, a combination that keeps rates well below the national average. Retail service is regulated. Summers are hot and long, making cooling the dominant load, while winters are mild enough that heating demand is secondary. Severe weather restoration costs are a recurring feature of rate cases.
For this appliance specifically, the difference works out to a saving of $29.55 a year against what the same slow cooker would cost at the national average rate. Run the identical appliance in Hawaii and it would cost $304 a year; in Idaho it would cost $72.12. That spread of $232 is entirely down to location.
That works out to roughly 5.6% of a typical Oklahoma household's annual electricity bill - modest individually, though appliances in this range add up.
Electricity in Oklahoma is cheap by national standards, which cuts both ways: running this slow cooker costs less than it would almost anywhere else, but the payback period on an efficiency upgrade is correspondingly longer. Replacing a working unit purely to save energy is harder to justify here.
Retail service in Oklahoma is regulated, so most households pay a tariff set through state rate cases rather than a shopped rate. The state average is a reasonable proxy, though your utility's specific tariff still varies.

About running a slow cooker
Despite running for hours, a slow cooker uses less energy than a 45-minute oven session because its draw is so low. On the low setting a typical model pulls around 150 watts, roughly the same as a large television, which makes all-day cooking genuinely cheap.
What actually changes the cost
- If your utility offers time-of-use pricing, shifting this load off-peak can cut its cost substantially without using any less energy.
How we worked this out
The arithmetic is simple and we would rather show it than hide it. Divide watts by 1,000 to get kilowatts, multiply by hours of use and by the duty cycle to get kilowatt-hours, then multiply by your rate:
200W ÷ 1000 × 8h = 1.600 kWh/day × 13.38¢ = $0.214 per day
One honest caveat: Oklahoma’s figure is a state average published by the EIA. Your own utility’s tariff, any time-of-use pricing, fixed monthly service charges and local taxes all shift the real number. Put your actual per-kWh rate into the calculator above for a figure that reflects your bill.
Questions about slow cooker running costs
How many watts does a slow cooker use?
A typical slow cooker draws about 200 watts while running, with most models falling between 150W and 300W. Check the nameplate label or manual for your specific unit - the range is wide enough that averages can mislead.
How much electricity does a slow cooker use per day?
At around 8 hours of use a day and a 100% duty cycle, that works out to roughly 1.6 kWh per day, or about 48 kWh a month. Your actual figure depends on your usage and model.
Why does the cost differ so much between states?
Residential electricity rates across the US range from about 12.35 cents per kWh in North Dakota to 46.62 cents in Hawaii - nearly a fourfold difference. The same slow cooker, used identically, therefore costs almost four times as much to run in the most expensive state as in the cheapest.
Is it cheaper to run a slow cooker at night?
Only if you are on a time-of-use or variable tariff. On a flat rate, the time of day makes no difference to cost. If you are on time-of-use pricing, off-peak hours are typically materially cheaper, and shifting this load can reduce its cost without reducing usage.
