Electricity Consumption Calculation

How to Calculate Electricity Consumption in Your Home?

Knowing how much electricity your appliances consume can help you control your expenses and make smart decisions about energy use. With a simple calculation, you can estimate how much electricity each device uses and how much that represents on your monthly bill.
Here’s a simple step-by-step guide to help you do it.

Basic Formula to Calculate Electricity Consumption

To find out how much energy an appliance uses, you can use the following formula:
Consumption (kWh) = Power (W) × Usage Time (h) ÷ 1,000

  • Power (W): This is the amount of energy the appliance uses per hour. You can find this information on the equipment label or in the manual.
  • Usage Time (h): This is the number of hours you use the appliance per day.
  • 1,000: Divide by one thousand to convert watts (W) to kilowatt-hours (kWh), which is the unit electricity companies use for billing.
Step-by-Step: Example Calculation

Imagine you have an air conditioner that uses 1,200 W (1.2 kW) and you use it for 6 hours a day:

  • Multiply the power by the daily usage time: 1,200 W × 6 h = 7,200 Wh (watt-hours)
  • Convert to kilowatt-hours (kWh): 7,200 ÷ 1,000 = 7.2 kWh per day
  • Multiply by the number of days in a month (assuming 30 days): 7.2 × 30 = 216 kWh per month

Calculate the monthly cost (average rate in Panama: $0.17/kWh):
216 × 0.17 = $36.72 per month

This is how you can estimate the cost of each appliance in your home.
