Calculate annual energy costs and savings from upgrading appliances
US average is ~$0.15/kWh
Override with actual usage
That old refrigerator in your garage might be costing you more than you think. Older appliances can use 2-3 times more electricity than modern Energy Star models. Over a year, that difference adds up to real money.
Our appliance energy calculator helps you understand exactly what your appliances cost to run—and how much you could save by upgrading. Whether you're trying to lower your electric bill, deciding if a new appliance makes financial sense, or just curious about where your energy dollars go, this tool gives you the numbers.
The results might surprise you. A refrigerator from 2010 might cost $150/year to run, while a new Energy Star model costs $50. Over a 10-year lifespan, that's $1,000 in savings—often more than the price difference between old and new.
We use EPA Energy Star data and industry standards to estimate appliance energy consumption:
That second fridge or old chest freezer might be your biggest energy drain. Know what's costing you.
Show your family (or yourself) the math behind buying a new appliance before the old one dies.
Energy efficiency isn't just about money. See how much CO2 you could prevent with upgrades.
Understand what portion of your electric bill comes from each major appliance.
Mistake: Using national average electricity rates
Solution: Rates vary dramatically by location. Check your bill—California pays 2-3x what some states pay.
Mistake: Ignoring secondary appliances
Solution: That second freezer, wine cooler, or dehumidifier might be using more energy than you'd expect.
Mistake: Overestimating savings from unplugging
Solution: Standby power is real but small. Focus on running efficiency, not phantom loads (which account for only 5-10% of use).
Mistake: Not accounting for usage patterns
Solution: A refrigerator runs 24/7, but you might only run your dryer once a week. Usage frequency matters.
Sometimes high energy consumption indicates an appliance needs service:
A modern Energy Star refrigerator costs about $40-60/year to run. Older models (10+ years) typically cost $100-150/year. Very old or oversized models can exceed $200/year.
HVAC leads the list (but isn't really an appliance). For actual appliances: water heaters, dryers, refrigerators, and washing machines are the biggest users. Electric ovens use a lot per hour but run less often.
Usually, yes. Energy Star appliances use 10-50% less energy than standard models. Over a 10-year lifespan, energy savings often exceed the price premium. Plus, many utilities offer rebates.
A little. Standby power accounts for 5-10% of home electricity use. Unplugging phone chargers and TVs helps, but the big savings come from using efficient appliances and running them smart.
