Formula and example

How the Electric Bill Cost Calculator USA – Estimate Appliance Electricity Cost Works

Electricity Cost = (Watts ÷ 1,000) × Hours Used × Electricity Rate

Watts show how much power an appliance needs. Dividing watts by 1,000 converts the number to kilowatts. Multiplying kilowatts by time gives kilowatt-hours, or kWh, which is the unit normally shown on an electric bill.

Example: a 1,500 watt space heater

A heater used for five hours per day at $0.18 per kWh uses 7.5 kWh daily and costs about $1.35 per day. Over 30 days, the estimated cost is $40.50.

Common questions

Electric Bill Cost Calculator USA – Estimate Appliance Electricity Cost FAQs

How do I calculate electricity cost from watts?

Divide watts by 1,000 to get kilowatts, multiply by the hours used, and then multiply by your electricity rate per kWh.

How much does a 1,500 watt heater cost to run?

A 1,500 watt heater uses 1.5 kWh per hour. At $0.18 per kWh, it costs about $0.27 per hour.

How much does an air conditioner cost per day?

The cost depends on wattage, running time, and electricity rate. A 1,500 watt AC used for eight hours at $0.18 per kWh costs about $2.16 per day.

What does kWh mean on an electric bill?

kWh means kilowatt-hour. It measures the amount of electricity used over time and is the unit most utilities use for billing.

Is this calculator exact?

It provides a practical estimate. Actual charges can vary because of appliance cycling, utility fees, taxes, seasonal rates, and energy efficiency.

Where can I find my electricity rate?

Check your latest utility bill for the energy charge, supply charge, or price per kWh. Enter the combined rate that best reflects what you pay.
