Standard Electricity Bill Component Breakdown

Component Description Typical Charges / Rates
Units Consumed Current meter reading minus previous meter reading (1 unit = 1 kWh) Varies by monthly usage
Energy Charge Step-by-step telescopic rate applied per unit slab ₹3.00 to ₹10.00+ / kWh
Fixed / Demand Charge Fixed fee per kW of sanctioned load per month ₹40.00 to ₹130.00 / kW / month
FPPPA / FAC Surcharge Fuel and Power Purchase Cost Adjustment per unit consumed ₹0.20 to ₹1.50 / kWh
Electricity Duty (ED) State government tax levied on energy and fixed charges subtotal 4% to 18% (or flat ₹0.15/unit)

Steps to Calculate Your Electricity Bill Online & Manually

1. Determine Total Units Consumed: Current - Previous Reading

Subtract last month's meter reading from the current meter reading to calculate net kWh consumption.

Example: 4,850 - 4,600 = 250 units.

2. Apply Step-by-Step Energy Slab Rates: Telescopic Slabs

Calculate base energy charges using your state DISCOM's slab tiers instead of multiplying total units by a single flat rate:

  • 0–100 units: 100 × ₹3.50 = ₹350.00
  • 101–200 units: 100 × ₹5.50 = ₹550.00
  • 201–250 units: 50 × ₹7.00 = ₹350.00
  • Total Energy Charge: ₹350 + ₹550 + ₹350 = ₹1,250.00

3. Add Fixed Charges & Fuel Surcharge: Fixed Load & FPPPA

Add monthly fixed charges for your sanctioned load.

Example: 2 kW × ₹80/kW = ₹160.00

Add the FPPPA surcharge.

Example: 250 units × ₹0.50 = ₹125.00

4. Add State Electricity Duty for Total Dues: Duty & Final Total

Calculate Electricity Duty.

Example: 5% on ₹1,410 subtotal = ₹70.50

Estimated total payable bill = ₹1,605.50
