Refrigerator Running Cost Calculator
Calculate the annual electricity cost of running your refrigerator based on wattage and usage cycle.
How It Works
Refrigerators run in cycles, averaging 8-12 hours per day at rated wattage. Enter your fridge wattage, daily run hours, and electricity rate to find the annual running cost.
Formula
Annual kWh = Watts x Hours/Day x 365 / 1000 | Cost = kWh x Rate
Frequently Asked Questions
How many watts does a refrigerator use?
Modern fridges use 100-200W when running. The compressor cycles on/off, averaging 8-12 hours per day, so typical annual consumption is 300-700 kWh.
When should I replace my old fridge?
Fridges over 15 years old can use 2-3x more electricity than modern Energy Star models. If your fridge costs more than $100/year to run, a new model often pays back in 3-5 years.
