How Much Electricity Does a Refrigerator Use?
A modern refrigerator uses 100-400 kWh per year, costing $15-65 annually. Standard fridges average 150 watts during compressor cycles but only run 8-10 hours per day, averaging 1-2 kWh daily. Use the Power Cost Calculator for exact costs.
Key Takeaways
- Refrigerators don't run continuously.
- Ice makers and water dispensers add 50-100 kWh per year.
- Keeping the fridge full actually improves efficiency.
Explanation
Refrigerators don't run continuously. The compressor cycles on and off to maintain temperature, typically running about 35% of the time. Newer Energy Star models are significantly more efficient than older units.
Size matters: a compact fridge (10-15 cu ft) uses about 300-400 kWh/year, while a large side-by-side (25+ cu ft) uses 500-700 kWh/year. Top-freezer models are typically most efficient.
Age is a major factor. A 20-year-old refrigerator might use 700+ kWh/year, while a new Energy Star model uses 300-400 kWh. Replacing an old fridge can save $50-100 annually in electricity.
Things to Know
- Ice makers and water dispensers add 50-100 kWh per year.
- Keeping the fridge full actually improves efficiency.
- Setting temperature too cold wastes energy—aim for 35-38°F for the fridge and 0°F for the freezer.
