1. What is a Monthly Electricity Consumption Calculator?

Definition: This calculator estimates the monthly energy consumption in kilowatt-hours (kWh) based on the power rating of an appliance and its monthly usage time.

Purpose: It helps homeowners and businesses estimate electricity usage and costs for budgeting and energy efficiency planning.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( E \) — Energy consumption (kWh)
• \( P \) — Power consumption (watts)
• \( t_{\text{month}} \) — Usage time per month (hours)

Explanation: The power consumption is multiplied by monthly usage time and divided by 1000 to convert watt-hours to kilowatt-hours.

3. Importance of Energy Consumption Calculation

Details: Understanding energy consumption helps in budgeting electricity costs, identifying energy-hungry appliances, and planning for energy efficiency improvements.

4. Using the Calculator

Tips: Enter the appliance's power rating in watts and the total time it runs per month in hours. All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: Where can I find an appliance's power rating?
A: Check the manufacturer's label, specification sheet, or product manual. It's often listed in watts (W) or kilowatts (kW).

Q2: How do I estimate monthly usage time?
A: Multiply daily usage hours by 30 (or actual days in month). For example: 2 hours/day × 30 days = 60 hours/month.

Q3: What's the average power consumption for common appliances?
A: Refrigerator: 150-400W, LED TV: 30-100W, Laptop: 50W, Incandescent bulb: 60W, LED bulb: 8-12W.

Q4: How can I reduce my electricity consumption?
A: Use energy-efficient appliances, turn off devices when not in use, utilize natural lighting, and maintain appliances properly.

Q5: How do I convert this to electricity cost?
A: Multiply kWh result by your local electricity rate (e.g., $0.12/kWh). Our Electricity Cost Calculator can help with this.
