Notes
- The annual figure assumes the federal test's hours of operation. A damp basement that runs all year can use more.
- Portable and whole-home models.
Work it out for your rate
Annual kWh ÷ 5.5 ≈ dollars per year
At the US average price of 18.19¢ per kWh, every 5.5 kWh costs about $1 (1 ÷ 0.1819 = 5.50). A refrigerator rated at 550 kWh a year costs about $100 a year to run.
Multiply the kWh figure by your own price per kWh from your bill. Your state's price may be far from the average: see rates by state.
