1. What is Electricity Usage Calculator for Tax?

Definition: This calculator estimates the electricity consumption in kilowatt-hours (kWh) based on appliance power and usage time.

Purpose: It helps individuals and businesses calculate their electricity usage for tax deductions, energy audits, or cost estimation.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( E \) — Electricity usage (kWh)
• \( P \) — Power consumption (watts)
• \( t \) — Usage time (hours)

Explanation: The power consumption multiplied by usage time gives watt-hours, which is then converted to kilowatt-hours by dividing by 1000.

3. Importance of Electricity Usage Calculation

Details: Accurate electricity usage calculation is essential for tax deductions on home office expenses, energy efficiency assessments, and budgeting utility costs.

4. Using the Calculator

Tips: Enter the appliance's power rating in watts and the total usage time in hours. Both values must be positive numbers.
