Formula & Calculation Methodology

Total Bill = Energy Charges (Slab 1 + Slab 2 + Slab 3) + Fixed Charges + Fuel Adjustment (FAC) + Electricity Duty (%).

Step-by-Step Worked Example

Consumption: 240 Units (kWh) | Fixed Charge: ₹110 | Duty: 5%

  1. Slab 1 (0-100 U @ ₹3.50) = ₹350
  2. Slab 2 (101-200 U @ ₹5.50) = ₹550
  3. Slab 3 (201-240 U @ ₹7.50) = ₹300
  4. Total Energy Charges = ₹1,200
  5. Fixed + Fuel Adjustment (₹108) = ₹218
  6. Electricity Duty (5%) = ₹71
  7. Total Monthly Bill = ₹1,489
Result: Total Units: 240 kWh | Monthly Estimated Bill: ₹1,489

How Electricity Slab Rates Work in India

State electricity boards (such as MSEDCL in Maharashtra, UPPCL in UP, BESCOM in Karnataka, TANGEDCO in Tamil Nadu, and BSES in Delhi) charge tiered rates where higher unit consumption incurs higher per-unit costs.

Using energy-efficient inverter ACs and BLDC ceiling fans can reduce monthly unit consumption by up to 35%.

Frequently Asked Questions
