How to Calculate Electricity Cost

Daily kWh = (Watts × Hours) ÷ 1000

Monthly kWh = Daily kWh × Days

Monthly Cost = Monthly kWh × Rate ($/kWh)

Example: A 100W TV running 5 hours/day at $0.13/kWh:
Daily: (100 × 5) / 1000 = 0.5 kWh
Monthly: 0.5 × 30 = 15 kWh → $1.95/month

Frequently Asked Questions

How do I calculate my appliance electricity cost?

Multiply the appliance wattage by hours used per day, divide by 1000 to get kWh, then multiply by your electricity rate. For example: 100W x 5 hours / 1000 = 0.5 kWh/day x $0.13 = $0.065 per day or about $1.95 per month.

Where can I find my appliance wattage?

Check the label on the back or bottom of the appliance, look in the user manual, or search online for your model number. Many appliances list watts (W) or amps (A) - if amps, multiply by 120V to get watts.

What is the average electricity rate in the US?

The US average electricity rate is around $0.13-0.15 per kWh, but varies significantly by state. California averages $0.22/kWh, while Louisiana is around $0.09/kWh. Check your utility bill for your exact rate.

Which appliances use the most electricity?

Heating and cooling systems use the most energy, followed by water heaters, dryers, and electric ovens. Running these for fewer hours or upgrading to energy-efficient models can significantly reduce your electricity bill.

How can I reduce my appliance energy costs?

Use appliances during off-peak hours, unplug devices when not in use, switch to LED bulbs, use ceiling fans instead of AC when possible, and replace old appliances with Energy Star certified models for maximum savings.
