How the IESCO Bill Calculator Works

Calculating your IESCO bill manually requires understanding NEPRA's progressive slab rates, consumer protection categories, and regulatory taxes. Our online calculator automates this calculation by applying the exact official slab tiers established for Islamabad Electric Supply Company (IESCO) residential consumers across Islamabad, Rawalpindi, Attock, Chakwal, and Jhelum.

Protected vs. Unprotected Slab Rates: If your monthly electricity consumption remains at or below 200 units for 6 consecutive billing months, you qualify for NEPRA's Protected Consumer Status, receiving heavily subsidized per unit rates. Consuming over 200 units in any single month converts your category to Unprotected.

IESCO Residential Tariff Slab Rates Structure

The table below illustrates the base per-unit rates (PKR/kWh) applied incrementally as your consumption crosses specific monthly slab thresholds:

Monthly Unit Range Protected Rate (PKR/kWh) Unprotected Rate (PKR/kWh)
1 – 100 Units Rs. 16.48 Rs. 23.59
101 – 200 Units Rs. 22.95 Rs. 30.07
201 – 300 Units N/A Rs. 34.26
301 – 400 Units N/A Rs. 39.15
401 – 500 Units N/A Rs. 41.36
501 – 600 Units N/A Rs. 42.78
601 – 700 Units N/A Rs. 43.92
Above 700 Units N/A Rs. 48.84
