How It Works

The calculator takes the appliance power in Watts, multiplies it by the number of hours used daily, and divides by 1000 to get daily kilowatt-hours (kWh). It then multiplies the daily kWh by your electricity rate to find the cost. Monthly estimates assume a 30-day period.

Example

A 1500W space heater used for 4 hours a day at a rate of $0.15/kWh costs (1500 × 4 / 1000) × $0.15 = $0.90 per day, or $27.00 per month.

Ways to reduce electricity costs

Switch to LED bulbs (uses 75% less energy than incandescent).
Unplug "phantom" loads when not in use.
Use a programmable thermostat to optimize heating and cooling.
Run high-energy appliances (like dryers) during off-peak hours if your provider has lower night rates.

Understanding your bill

Base charges: A fixed monthly fee regardless of usage.
Variable charges: The cost based on how many kWh you consumed.
Taxes and surcharges: Government-imposed fees or fuel adjustment costs.

Frequently Asked Questions

How is electricity cost calculated?

Electricity cost is calculated by multiplying the energy consumed in kilowatt-hours (kWh) by the price per kWh. Energy in kWh is (Watts × Hours used) / 1000.

What is a kWh?

A kilowatt-hour (kWh) is a measure of energy. It is the amount of power (1,000 watts) consumed in one hour. Most electricity bills charge by the kWh.

How do I find appliance wattage?

Wattage is usually found on a label on the back or bottom of the appliance, or in its user manual. Look for a number followed by "W" or "Watts".

Does this include tiered pricing?

This calculator uses a flat rate for simplicity. If your provider uses tiered pricing (where the rate increases as you use more), enter your average rate or the rate for your highest tier for a more conservative estimate.
