How Much Does It Cost to Run a Chest Freezer in South Carolina? (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 $0.016 per hour, or about $3.73 per month at 8 hours a day in South Carolina. Average running cost
| Wattage | Per hour | Per day | Per month | Per year |
|---|---|---|---|---|
| Low 60 W | $0.009 | $0.075 | $2.24 | $27.24 |
| Typical 100 W | $0.016 | $0.12 | $3.73 | $45.41 |
| High 200 W | $0.031 | $0.25 | $7.46 | $90.81 |
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 South Carolina, with electricity at 15.6¢ per kWh (source: EIA Table 5.6.A, 2026-06), a typical chest freezer costs $0.016 per hour and about $45.41 per year at 8 hours a day.

Each $1.00 of electricity buys roughly 64.3 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 $48.20 a year in South Carolina.
- Replacing one that still works pays back in 12.4 years.
- When yours needs replacing anyway, the extra cost of the efficient model pays back in 2.5 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
