Estimate electricity cost from watts, kilowatts, amps, volts, kWh usage, runtime, electric rate, fixed fees, and taxes. This calculator helps estimate appliance cost, daily cost, monthly cost, and yearly electricity cost.
Energy use:
The calculator estimates kWh from watts, kilowatts, amps, known kWh, or multiple appliance rows.
Energy cost:
The calculator multiplies kWh by your electric rate.
Total cost:
Fixed fees and tax/extra fee percentages are added to estimate a fuller electricity cost.
An electricity cost calculator helps estimate how much it costs to run appliances, lights, heaters, EV chargers, shop equipment, or an entire home.
It can help compare appliance costs, estimate monthly utility cost, plan EV charging cost, estimate heater or AC cost, and understand how runtime affects your electric bill.
Your result shows total electricity cost, energy cost, total kWh, daily cost, monthly cost, yearly cost, fixed fees, taxes, average watts, and appliance row estimates.
Multiply kilowatt-hours used by your electric rate. For example, 600 kWh at $0.15 per kWh costs $90 before fixed fees and taxes.
Divide watts by 1,000 to get kilowatts, then multiply by hours used. A 1,500 watt appliance running 8 hours uses 12 kWh.
Electric bills may include fixed customer charges, delivery charges, riders, minimum charges, time-of-use pricing, taxes, and other fees.
Yes. Enter the charger watts or kilowatts, runtime, number of days, and your electric rate to estimate EV charging cost.
