About refrigerator running costs
A refrigerator is rated at its compressor power, but the compressor only runs about a third of the day. Annual kWh on the energy label is the best guide.
Typical sizes: 100 W, 150 W, 200 W, 300 W.
How to spend less: Keep it away from the oven, keep the door seals clean and set it to 37°F (3°C).
What this estimate assumes
- The appliance draws its full stated wattage the whole time it is on. Real units with a thermostat cycle off and cost less.
- Wattage is the typical label value, not a measured value. Check the label on your own appliance.
- The rate is an approximate residential average in Ohio. Your bill may include fixed fees, tiers or time-of-use pricing. Edit the rate above.
- A month is 30 days and a year is 365 days.
