Sub Meter Bill Formula:
| From: | To: |
Sub meter bill calculation determines electricity costs for individual units in multi-tenant buildings using submeter readings. It provides accurate billing based on actual consumption rather than estimated or averaged rates.
The calculator uses the sub meter bill formula:
Where:
Explanation: The calculation determines actual electricity consumption by subtracting the previous reading from the current reading, then multiplies by the applicable rate to calculate the total bill amount.
Details: Sub meter billing ensures fair and accurate electricity cost allocation among multiple tenants, promotes energy conservation, and provides transparency in utility billing for property managers and residents.
Tips: Enter current and previous kWh readings from the submeter, along with the applicable electricity rate per kWh. Ensure current reading is greater than or equal to previous reading for accurate calculation.
Q1: What is the difference between main meter and sub meter?
A: Main meter measures total building consumption, while sub meters measure individual unit consumption for fair cost allocation.
Q2: How often should sub meter readings be taken?
A: Typically monthly, coinciding with billing cycles, to ensure accurate and timely billing.
Q3: What if current reading is less than previous reading?
A: This indicates a meter reset or error. Verify readings and consult with the utility provider or property manager.
Q4: Are there different rate structures for electricity?
A: Yes, rates may vary by time-of-use, tiered consumption, or demand charges. Use the applicable rate for accurate billing.
Q5: Can this calculator be used for other utilities?
A: The same principle applies to water and gas submetering, though rates and units will differ.
