Cost Per Kilowatt Calculator

Calculate the cost per kilowatt of electricity consumption, helping you understand and optimize your energy expenses.

Input Parameters

Calculation Results

Calculation Formula

Daily Cost = Power Consumption (kW) × Usage Hours (hours) × Electricity Rate ($/kWh)

Where:
Power Consumption (kW): The electrical power used by your device in kilowatts
Usage Hours (hours): The number of hours the device is used per day
Electricity Rate ($/kWh): The cost of electricity per kilowatt-hour

Learn how to use the Cost Per Kilowatt Calculator calculator and its working principles

How to Use the Calculator

  1. Enter the power consumption of your device in kilowatts (kW).
  2. Input the number of hours the device is used per day.
  3. Provide the electricity rate in your area (measured in dollars per kilowatt-hour, $/kWh).
  4. Click the "Calculate" button to determine the daily, monthly, and yearly costs.

Understanding the Formula

The calculator uses the following formula to calculate costs:

Cost = Power Consumption (kW) × Usage Hours (hours) × Electricity Rate ($/kWh)

This formula helps you understand how much you are spending on electricity based on your device's power consumption and usage patterns.

Practical Applications

  • Comparing the costs of different appliances.
  • Identifying energy-saving opportunities.
  • Understanding your electricity bill components.
  • Planning energy-efficient upgrades for your home or business.

Example

If you have a device with a power consumption of 2 kW that runs for 5 hours a day, and your electricity rate is $0.15 per kWh, the costs would be:

  • Daily Cost: 2 kW × 5 hours × $0.15/kWh = $1.50
  • Monthly Cost: $1.50 × 30.44 days = $45.66
  • Yearly Cost: $1.50 × 365.25 days = $547.88
