Calculate the annual electricity cost of your refrigerator. Enter annual kWh from the EnergyGuide label and your rate to see yearly and monthly costs.
Your refrigerator runs 24 hours a day, 365 days a year, making it one of the largest ongoing electricity consumers in your home. A modern ENERGY STAR refrigerator uses 400–600 kWh per year, while older models from the 1990s or earlier can use 1,000–2,000+ kWh. At $0.14/kWh, a new efficient fridge costs $56–$84/year while an old one might cost $140–$280.
The EnergyGuide yellow label on every new refrigerator lists the estimated annual kWh consumption, making it easy to calculate running costs. Factors that affect actual usage include ambient temperature, door-opening frequency, thermostat setting, coil cleanliness, and gasket condition.
This calculator takes the annual kWh rating and your electricity rate to show you exactly what your refrigerator costs to operate. Use it to decide whether replacing an old, inefficient fridge will pay for itself through energy savings.
This analytical approach supports both immediate cost reduction and long-term sustainability goals, helping organizations balance economic and environmental priorities in their energy management.
Refrigerators run nonstop, so even small efficiency differences compound over years. This calculator shows the true annual cost, helping you evaluate whether upgrading an old fridge saves enough money to justify the purchase. Consistent measurement creates a reliable baseline for tracking energy efficiency improvements and validating the impact of conservation measures and equipment upgrades over time.
Annual Cost ($) = Annual kWh × Rate ($/kWh)
Result: $70.00/year
A refrigerator rated at 500 kWh/year costs 500 × $0.14 = $70.00 per year to operate. That's about $5.83 per month. An older model using 1,200 kWh would cost $168/year.
Refrigerator efficiency has improved dramatically. A 1980s fridge used 1,400–2,000 kWh/year. A 2000s model uses 500–700 kWh. Today's ENERGY STAR models use 400–500 kWh. If you have a fridge from before 2000, replacing it could cut its energy use by 50–75%.
Millions of households keep a second fridge in the garage for beverages and overflow storage. These are often the oldest, least efficient units in the house, and garages expose them to extreme temperatures that increase energy use. A garage fridge can easily cost $150–$250/year to operate.
Keep the refrigerator 3/4 full for optimal thermal mass. Clean condenser coils at least once a year. Check door gaskets and replace if worn. Set temperatures to 37–40°F for the fridge and 0°F for the freezer. Place the fridge away from heat sources and direct sunlight.
A new ENERGY STAR refrigerator costs $40–$85/year. A standard model costs $60–$120/year. An old fridge from the 1990s or earlier can cost $140–$280/year. The EnergyGuide label provides the estimated annual kWh for comparison.
If your fridge is 15+ years old, it likely uses 2–3 times more electricity than a modern ENERGY STAR model. Replacing it can save $80–$200/year. The savings typically pay for a new basic fridge in 3–5 years.
Generally yes, but not proportionally. A 25 cu ft fridge might use 500–600 kWh vs 400–450 for an 18 cu ft model. French door and side-by-side styles tend to use slightly more than top-freezer models of the same size.
Each door opening lets cold air escape and warm air in, requiring the compressor to work harder. Brief, purposeful openings have minimal impact. Standing with the door open or opening it frequently (especially in hot kitchens) noticeably increases energy use.
Top-freezer models are generally the most energy-efficient, followed by bottom-freezer, then French door and side-by-side. Within each type, ENERGY STAR certified models use 10‒15% less energy than standard models.
Yes, a second fridge (especially an old one) in an unconditioned garage can cost $100–$200+ per year. The extreme temperatures in a garage (hot in summer, cold in winter) force the compressor to work much harder. Consider whether you truly need it.
