Electricity Usage Calculator: How to Track Your Power Consumption with Example

Are you worried about high electricity bills? Do you want to understand how much power your electrical devices consume every day? An electricity usage calculator is the perfect tool to help you estimate and control your energy costs. In this post, you’ll learn how to use a simple calculator, the formula behind it, and see a step-by-step example.

What is an Electricity Usage Calculator?

An electricity usage calculator helps you estimate the amount of energy consumed by your electrical appliances. By entering the power rating (in watts), operating hours, and days of usage, you can instantly calculate how much electricity each device uses – and how it impacts your monthly bill.

Formula for energy usage

Example

Example: Calculating Electricity Usage for a Refrigerator
Suppose your refrigerator has a power rating of 150 watts and you use it 24 hours a day, every day for 30 days. The electricity rate is ₹7 per kWh.

Step 1: Calculate energy consumed:
Energy (kWh) = (150 x 24 x 30) / 1000 = 108 kWh

Step 2: Calculate cost:
Total Cost = 108 x 7 = 756/-

Result:
Your refrigerator will consume 108 kWh per month, costing you 756/- on your electricity bill.

Benefits of Knowing an Electricity Usage

• Track which appliances use the most power
• Optimize energy usage and reduce bills
• Plan for energy-efficient upgrades
• Immediate cost estimates for new devices

Try It Yourself!

Use the calculator for your fridge, TV, washing machine, or any household device. Just input the wattage, daily use, and days – and find the real monthly cost.

Frequently Asked Questions
