1. What Is Sub-meter Bill Calculation?

Sub-meter bill calculation is a method used to distribute the total electricity bill among multiple users or units based on their individual consumption measured by sub-meters. This ensures fair and proportional billing according to actual usage.

2. How Does The Calculator Work?

The calculator uses the sub-meter bill formula:

\[ Sub\ Bill = \frac{Sub\ Usage}{Main\ Usage} \times Main\ Bill \]

Where:

\( Sub\ Bill \) — Individual sub-meter bill amount
\( Sub\ Usage \) — Electricity consumption measured by sub-meter (kWh)
\( Main\ Usage \) — Total electricity consumption from main meter (kWh)
\( Main\ Bill \) — Total electricity bill amount

Explanation: This formula calculates the proportional share of the total bill based on the ratio of individual consumption to total consumption.

3. Importance Of Sub-meter Billing

Details: Sub-meter billing promotes energy conservation, ensures fair cost distribution, helps identify high-consumption areas, and provides accurate billing for multi-tenant properties, shared spaces, and commercial establishments.

4. Using The Calculator

Tips: Enter sub-meter usage in kWh, main meter total usage in kWh, and the total main bill amount. All values must be positive numbers greater than zero for accurate calculation.

5. Frequently Asked Questions (FAQ)
