Estimate your monthly electricity bill in Pakistan based on units consumed and current NEPRA slab tariffs. Covers the full billing structure including fuel adjustment charges, fixed charges, GST, and other levies that make Pakistan's electricity bills complex.
Step 1. Enter the total units consumed from your meter reading for the month.
Step 2. Enter the fuel adjustment charge (FAC) per unit — published monthly by NEPRA and printed on recent bills.
Step 3. Enter the fixed monthly charge from your tariff schedule.
Step 4. The calculator applies NEPRA slab rates, adds FAC, GST at 18%, and other standard levies.
With the default inputs loaded in the form, the calculator produces a starting result you can use as a baseline. Change one field at a time to compare a new scenario.
Pakistan's electricity is billed on a slab-rate system — higher consumption pushes all units into a higher rate band. This means consuming even one unit above a slab boundary shifts your entire bill into the higher rate.
NEPRA approves tariffs; fuel adjustment charges (FAC) fluctuate monthly based on actual generation costs versus the approved reference fuel cost. FAC can be positive (extra charge) or negative (rebate) depending on fuel prices.
The bill also includes GST at 18%, electricity duty, Neelum-Jhelum surcharge, and a TV licence fee. These additions can add 25-35% to the base energy charges.
Protected consumers (consuming ≤50 units/month) receive a significantly subsidized tariff. The subsidy structure for low-income consumers has been revised multiple times in recent years as NEPRA implements cost-reflective tariff reforms.
Switching from energy-inefficient appliances — particularly old air conditioners, refrigerators, and geysers — to Energy Rating label certified alternatives can reduce consumption by 30-50% and fundamentally change your slab position.
Your actual bill may differ due to arrears, meter rent, peak-hour charges (for ToU meters), or updated fuel adjustment charges not yet reflected here. Always check the current month's NEPRA FAC notification.
FAC is a variable charge added or subtracted based on actual fuel cost of generation versus the approved reference fuel cost in the NEPRA tariff. It is published monthly and can significantly affect your bill.
Residential slabs are 1-100 units, 101-200, 201-300, 301-700, and above 700 units per month. Each slab has a progressively higher per-unit rate. Consuming even one unit above a boundary applies the higher rate to ALL units in that billing month.
Protected consumers use ≤50 units/month and receive a heavily subsidized rate. Unprotected consumers (51+ units) pay commercial rates with no subsidy. The protected category is reviewed periodically by the government.
