What is an Energy Cost Calculator?

An energy cost calculator is a simple tool that calculates how much electricity your appliances use and what that costs you. By entering details like an appliance’s power rating and daily usage, you get an instant estimate of your power consumption in rupees. It’s designed for everyone—homeowners looking to cut costs, students studying electrical engineering, electricians planning installations, or eco-conscious users exploring energy-efficient options. Whether you’re curious about your fridge’s running cost or planning a solar setup, this kWh calculator takes the guesswork out of how to calculate energy bill.

Formula Used in the Calculator

The energy usage calculator relies on a simple yet powerful formula:

Energy Cost = Power (kW) × Time (hours) × Rate per kWh

Here’s what each part means:

• Power (kW): The appliance’s power rating in kilowatts. Most appliances list watts (W), so divide by 1,000 to get kW. For example, a 2,000W geyser is 2 kW.
• Time (hours): How many hours you use the appliance daily. A fan running for 10 hours? That’s your time input.
• Rate per kWh: The cost of one kilowatt-hour of electricity, found on your bill. In India, it’s typically ₹6–₹10/kWh, depending on your provider.

Multiply the daily cost by 30 for a monthly estimate. This formula is the backbone of our power consumption tool, making it easy to understand your appliance electricity cost.

How to Use the Energy Cost Calculator (Step-by-Step)

Using our electricity cost calculator is as simple as plugging in a light bulb. Follow these steps:

1. Go to the Calculator: Visit our Energy Cost Calculator page.
2. Enter Power Rating: Check your appliance’s wattage (on the label or manual). For example, a TV might use 100W.
3. Add Daily Usage Hours: Estimate how long the appliance runs daily. A TV on for 4 hours? Enter 4.
4. Input Electricity Rate: Find your rate per kWh on your electricity bill (e.g., ₹7.5/kWh). Not sure? Check the FAQ below.
5. Click Calculate: The tool displays your energy cost for daily and monthly usage in rupees.

The result? Clear, instant insights into your appliance electricity cost. Want to explore more? Try our Watt to Amp Calculator for other electrical calculations.

Example Calculation

Let’s see the kWh calculator in action with two practical examples:

Example 1: Air Conditioner

• Appliance: 1,500W AC
• Daily Usage: 6 hours
• Electricity Rate: ₹8/kWh

Steps:

1. Convert to kW: 1,500W ÷ 1,000 = 1.5 kW
2. Calculate: Energy Cost = 1.5 kW × 6 hours × ₹8/kWh = ₹72/day
3. Monthly Cost: ₹72 × 30 days = ₹2,160/month

Your AC could cost ₹2,160 a month—good to know, right?

Example 2: LED Bulb

• Appliance: 10W LED bulb
• Daily Usage: 5 hours
• Electricity Rate: ₹7/kWh

Steps:

1. Convert to kW: 10W ÷ 1,000 = 0.01 kW
2. Calculate: Energy Cost = 0.01 kW × 5 hours × ₹7/kWh = ₹0.35/day
3. Monthly Cost: ₹0.35 × 30 days = ₹10.5/month
