Estimate electricity cost from kilowatt-hours, watts, kilowatts, runtime hours, days, electric rate, fixed charges, and taxes. This calculator helps estimate daily, monthly, yearly, and appliance electricity cost.
Energy use:
The calculator estimates kilowatt-hours from known kWh, watts, kilowatts, amps, or multiple appliance rows.
Energy cost:
The calculator multiplies kWh by your electric rate.
Total cost:
Fixed monthly fees and tax percentage can be added for a fuller bill estimate.
A kWh cost calculator helps estimate how much an appliance, circuit, room, garage, shop, EV charger, or home electricity usage may cost.
It can help with comparing appliances, estimating EV charging cost, checking heater or AC cost, planning monthly utility cost, and understanding how runtime affects your electric bill.
Your result shows total kWh, energy cost, fixed fees, tax/fees, total cost, daily cost, monthly cost, yearly cost, average kWh per day, and appliance row cost estimates.
Multiply the number of kilowatt-hours used by your electric rate. For example, 600 kWh at $0.15 per kWh costs $90 before fees and taxes.
Divide watts by 1,000 to get kilowatts, then multiply by hours used. A 1,500 watt heater used for 8 hours uses 12 kWh.
Utility bills may include fixed customer charges, delivery charges, riders, taxes, demand charges, tiered rates, and other fees.
Yes. Enter the charger wattage or kW, runtime, days, and electric rate to estimate EV charging electricity cost.
