Cost to run a refrigerator

Laundry & kitchen · typical wattage 150 W (100 W-800 W)

A refrigerator draws about 100 W-800 W (typically 150 W). At typical usage it uses about 600 kWh/year, which costs roughly $9.28/month and $111/year at the US average residential rate of 18.56¢/kWh (March 2026). At a high-rate state like California (33.35¢) it costs more; at a low-rate state like Washington (14.40¢) it costs less.

Wattage source & how to save

A modern fridge uses roughly 400–800 kWh/year. It runs 24/7 but the compressor cycles, averaging around 100–200 W; older units use far more.

Tip to cut the cost: Keep coils clean and the fridge full; replacing a pre-2001 unit can save over 1,000 kWh/year.

Frequently asked questions

How much does it cost to run a refrigerator?

At the US average residential rate of 18.56¢/kWh, a refrigerator (about 100 W-800 W, typically 150 W) used at typical levels costs roughly $9.28 per month and $111 per year. Your cost depends on your exact wattage, usage and local rate. Use the calculator for an exact figure.

How many watts does a refrigerator use?

A modern fridge uses roughly 400–800 kWh/year. It runs 24/7 but the compressor cycles, averaging around 100–200 W; older units use far more.

How much electricity does a refrigerator use per year?

About 600 kWh per year at typical usage. This is expressed as annual kWh because the device cycles rather than running at a fixed wattage.

How can I cut the running cost of a refrigerator?

Keep coils clean and the fridge full; replacing a pre-2001 unit can save over 1,000 kWh/year.
