How Much Does It Cost to Run a Chest Freezer in Illinois? (2026)
Chest freezers are more efficient than upright freezers because cold air stays inside when the lid opens. A modern 200 litre chest freezer uses around 200 to 300 kWh a year; older units can use double that.
A typical chest freezer (100 W) costs $0.020 per hour, or about $4.77 per month at 8 hours a day in Illinois. Average running cost
| Wattage | Per hour | Per day | Per month | Per year |
|---|---|---|---|---|
| Low 60 W | $0.012 | $0.095 | $2.86 | $34.85 |
| Typical 100 W | $0.020 | $0.16 | $4.77 | $58.08 |
| High 200 W | $0.040 | $0.32 | $9.55 | $116.16 |
Formula: watts ÷ 1000 × hours × price per kWh. Typical use is 8 h/day ≈ 292 kWh per year.
One hour of a chest freezer (0.10 kWh) is the same electricity as
- 2.0hours of a fridge
- 2.2hours of a laptop
- 10hours of Wi-Fi
- 11hours of an LED bulb
In Illinois, with electricity at 19.9¢ per kWh (source: EIA Table 5.6.A, 2026-06), a typical chest freezer costs $0.020 per hour and about $58.08 per year at 8 hours a day. That is about 8% more than the national average for the US ($4.40 per month), because electricity in Illinois costs 19.9¢ per kWh against 18.3¢ nationally. Each $1.00 of electricity buys roughly 50.3 hours of use.
How to lower the cost of running a chest freezer
- Keep it in a cool garage or basement, not a hot utility room.
- Keep it at least two-thirds full. Frozen mass holds cold through door openings and power cuts.
- Defrost when ice exceeds about 5 mm. Ice buildup makes the compressor run longer.
Is an efficient chest freezer worth it?
Freezer from the 2000s in a garage: about 480 kWh a year. Current A or B-rated chest freezer: about 170 kWh. The difference is worth $61.66 a year in Illinois.
- Replacing one that still works pays back in 9.7 years.
- When yours needs replacing anyway, the extra cost of the efficient model pays back in 1.9 years.
Usage assumed: always on. Typical prices: $600.00 for the efficient model, $120.00 more than a basic one. Work it out with your own prices
