Your monthly electricity bill consists of several components. Understanding each helps you identify why your bill is high and where you can save.
Based on NEPRA 2026 tariff slabs. The more units you consume, the higher the per‑unit rate (progressive structure). Protected consumers (≤200 units) pay lower rates across all slabs.
A fixed amount applied every month regardless of consumption: Rs 200 for ≤100 units, Rs 300 for 101‑200 units, Rs 400 for >200 units.
Applied on the total of Energy Charges + Fixed Charges. This is a government levy.
A variable monthly surcharge reflecting changes in international fuel prices. FCA can be positive (adds to your bill) or negative (reduces your bill). It is not included in our base calculator – check your DISCO’s latest FCA rate.
A small per‑unit levy (approx Rs 0.50‑1.00 per unit) to finance the NJ hydropower project.
Rs 35 per month if you own a television. Appears on most bills.
📌 Example Calculation: For 300 units (non‑protected): Energy = (50×3.95)+(50×7.74)+(100×13.01)+(100×33.10) = Rs 13,200. Fixed = Rs 400. Subtotal = Rs 13,600. GST 18% = Rs 2,448. FCA (say Rs 3.5/unit) = Rs 1,050. NJ surcharge = Rs 150. Total = Rs 17,248.
