Cost to run a chest freezer in Maine
At Maine’s average residential rate of 28.63¢ per kWh, a chest freezer drawing 200W for 24 hours a day costs about $12.55 a month. Change the numbers below to match how you actually use yours.
Quick answer
Based on 200W at a 30% duty cycle (this equipment cycles on and off rather than drawing full power continuously) and 28.63¢/kWh, the Maine average for May 2026.

Why the cost differs in Maine
Maine has the 46th cheapest residential electricity of the 51 US states and territories we track, at 28.63¢ per kWh against a national average of 18.44¢. That is +55.3% compared with the national figure. Maine combines high winter heating demand with constrained regional transmission, a costly pairing. Retail supplier choice is available, so contracted rates vary. Heat pump adoption here is among the highest in the country, which is shifting the winter load profile: households that once burned oil now draw electricity through the coldest months, when New England generation costs peak.
For this appliance specifically, the difference works out to an extra $53.56 a year over what the same chest freezer would cost at the national average rate. Run the identical appliance in Hawaii and it would cost $273 a year; in Idaho it would cost $64.91. That spread of $208 is entirely down to location.
That works out to roughly 5.0% of a typical Maine household's annual electricity bill - modest individually, though appliances in this range add up.
Because Maine is among the most expensive states for electricity, efficiency upgrades pay back faster here than almost anywhere. A more efficient chest freezer that saves a given number of kilowatt-hours saves noticeably more money in Maine than the same upgrade would in a cheap-power state.
Because Maine has retail supplier choice, the state average blends many different contracted rates. If you have shopped for a plan, your own price per kWh is the number to put in the calculator.

About running a chest freezer
Chest freezers are more efficient than upright models because cold air does not spill out when opened. A garage freezer in an unheated space works harder in summer and easier in winter.
What actually changes the cost
- Nameplate wattage is not running cost. This chest freezer draws about 200W when active, but cycles roughly 30% of the time it is switched on, so effective consumption is near 60W.
- Models vary widely, from about 100W to 400W. Check the nameplate on your own unit rather than assuming an average, because the spread is more than 2x.
- Because this runs continuously, small wattage differences between models compound into large annual differences.
- 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 × 24h × 30% = 1.440 kWh/day × 28.63¢ = $0.412 per day
One honest caveat: Maine’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 chest freezer running costs
How many watts does a chest freezer use?
A typical chest freezer draws about 200 watts while running, with most models falling between 100W and 400W. Check the nameplate label or manual for your specific unit - the range is wide enough that averages can mislead.
How much electricity does a chest freezer use per day?
At around 24 hours of use a day and a 30% duty cycle, that works out to roughly 1.44 kWh per day, or about 43 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 chest freezer, 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 chest freezer 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.
