Cost to run a chest freezer
Short answer
Running a chest freezer (~100W, ~8 hrs/day) costs about $0.13/day, $4/month, or $49/year at the U.S. average of 16.8¢/kWh.

What makes a chest freezer cost what it does
A chest freezer draws about 100W and runs roughly 8 hours a day in a typical home. Run the standard formula — watts ÷ 1,000 × hours × your electricity rate — and at the U.S. average of 16.8¢/kWh that's about $0.13/day, $4/month, or $49/year.
Two things move that figure most: how many hours it actually runs and what you pay per kilowatt-hour. It draws power in short bursts, so total hours of use matter more than its peak wattage. A chest freezer nominally at 100W but used half as often costs roughly half as much — usage, not the nameplate rating, decides the bill.
Your electricity rate does the rest of the work. The same chest freezer costs about $31/year in a low-rate state like Idaho (10.5¢/kWh) but $123/year in Hawaii (42¢/kWh) — roughly a 4× swing for the identical appliance.
What determines the cost
| Factor | Effect on cost |
|---|---|
| Wattage | A chest freezer pulls about 100W while running |
| Hours of use | Typically ~8 hr/day — double the hours and you double the cost |
| Electricity rate | What you pay per kWh (U.S. average 16.8¢) scales the whole bill |
| Efficiency & age | Newer, Energy-Star models draw less for the same job |
| Settings & duty cycle | It draws power in short bursts, so total hours of use matter more than its peak wattage |
| Standby draw | Many devices keep sipping power even when idle or 'off' |
Cost by electricity rate
Yearly cost to run this chest freezer at a low, average, and high state electricity rate.
| Rate | Yearly cost |
|---|---|
| Low rate (Idaho, 10.5¢) | $31/yr |
| U.S. average (16.8¢) | $49/yr |
| High rate (Hawaii, 42¢) | $123/yr |
How to cut what a chest freezer costs
- Cut runtime first: every hour you don't run the chest freezer is the cleanest saving, since cost is hours × watts × rate.
- Check your actual electricity rate — if you're above the 16.8¢ U.S. average, the chest freezer costs more than the headline figure here.
- Right-size the job: for a chest freezer, smaller batches and shorter cycles cut energy without changing the result.
- Enter your own wattage, hours, and rate in the calculator for a chest freezer figure tuned to your home.

Frequently asked questions
How much does it cost to run a chest freezer?
About $0.13 per day, $4 per month, or $49 per year at the U.S. average of 16.8¢/kWh, assuming ~100W for ~8 hours a day.
How many watts does a chest freezer use?
A typical chest freezer draws about 100 watts when running. Your model may differ — check its label or a plug-in power meter and enter the real number in the calculator.
How can I cut the cost of running a chest freezer?
Run it less, use a more efficient model, and check whether your utility offers cheaper off-peak (time-of-use) rates. Costs also vary 4× by state, so your local rate matters a lot.
