Estimate how much an appliance costs to run from watts, kilowatts, quantity, runtime, duty cycle, electric rate, and days used. This calculator shows daily, monthly, yearly, and lifetime appliance energy cost.
Power:
The calculator uses watts, kilowatts, amps and volts, or known kWh to estimate appliance energy use.
Runtime:
Daily hours, days per month, months per year, quantity, and duty cycle are applied to estimate energy use over time.
Cost:
Estimated kWh is multiplied by your electric rate to estimate daily, monthly, and yearly appliance cost.
An appliance energy cost calculator helps estimate how much it costs to run one appliance or compare multiple appliances.
It can help compare heaters, air conditioners, refrigerators, lights, TVs, dryers, ovens, EV chargers, pumps, tools, and other household or shop equipment.
Your result shows daily cost, monthly cost, yearly cost, appliance kWh, cost per hour, cost per day, cost per month, cost per year, watts, kilowatts, runtime, quantity, duty cycle, and comparison appliance estimates.
Divide appliance watts by 1,000 to get kilowatts. Multiply by hours used, then multiply by your electric rate.
A 1,500 watt appliance is 1.5 kW. If it runs for 6 hours at $0.15/kWh, it costs about $1.35 per day.
Duty cycle estimates how much of the selected time the appliance is actually running. A refrigerator may be plugged in 24 hours but may not run at full wattage the entire time.
Actual cost can vary because appliances cycle on and off, utility rates vary, equipment efficiency changes, and bills may include fixed fees, delivery charges, taxes, and time-of-use pricing.
