1. What is a Monthly Energy Consumption Calculator?

Definition: This calculator estimates the monthly energy usage in kilowatt-hours (kWh) based on device power consumption and daily usage time.

Purpose: It helps homeowners and businesses understand and manage their electricity consumption and costs.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( E \) — Energy consumption (kWh)
• \( P \) — Power consumption (Watts, W)
• \( t \) — Daily usage time (hours, h)
• 30 — Days per month
• 1000 — Conversion from Watts to kilowatts

Explanation: The formula calculates daily energy use, scales it to monthly usage, and converts from watt-hours to kilowatt-hours.

3. Importance of Energy Consumption Calculation

Details: Understanding energy usage helps in budgeting electricity costs, identifying energy-saving opportunities, and reducing environmental impact.

4. Using the Calculator

Tips: Enter the device's power consumption in Watts and daily usage time in hours. All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: Where can I find my device's power consumption?
A: Check the device label, manual, or manufacturer specifications. Some devices list power in amps - multiply by voltage (usually 120V) to get Watts.

Q2: Why divide by 1000 in the formula?
A: This converts watt-hours to kilowatt-hours (kWh), the standard unit for electricity billing.

Q3: What if my usage varies daily?
A: Use an average daily usage time. For more accuracy, calculate separately for different usage patterns.

Q4: How can I estimate costs from this result?
A: Multiply the kWh result by your electricity rate (check your utility bill, typically $0.10-$0.30 per kWh).

Q5: Does this account for standby power?
A: No, this calculates active usage only. For complete energy picture, consider adding standby consumption.
