How Electricity Bill is Calculated in General (India)
In India, electricity is billed based on slightly varying structures from state to state, but the underlying principle remains the same. Electricity boards measure power consumption in kilowatt-hours (kWh), commonly known as "Units."
Here is the general breakdown of how the electricity bill is calculated:
1. Identify Your Meter Reading (Units Consumed)
If you want to know how to calculate electricity bill from meter reading, you must first find out your total units consumed in the billing cycle (usually a month or two months).
- Current Reading minus Previous Reading = Units Consumed
- For example: If your previous reading was
1500 kWhand current is1750 kWh, your consumption is250 units.
2. Slab-based Tariffs (Energy Charges)
Most state electricity boards employ a "telescopic" or slab-based billing system. This means the per-unit cost increases as your consumption moves to a higher slab.
- Example Slab:
- 0-100 units: ₹3.00/unit
- 101-200 units: ₹4.50/unit
- 201-500 units: ₹6.00/unit
3. Fixed Charges
This is a fixed monthly/bimonthly fee levied based on your sanctioned load capacity (e.g., 2kW, 5kW or more), irrespective of how much electricity you consume.
4. Additional Taxes and Surcharges
- Electricity Duty / Tax: Govt mandates a fixed percentage of tax on the total energy charge.
- Fuel Surcharge / FPPCA: Sometimes, boards add a fuel surcharge if the cost of generating power fluctuates.
- Other Levies: Including regulatory charges or municipal taxes depending on your locality.
Total Electricity Bill = Energy Charges + Fixed Charges + Taxes & Surcharges - Subsidies (if any)
