About the tool
What is an IESCO Bill Calculator?
An IESCO bill calculator is an online tool that estimates your bill based on units consumed and connection category. IESCO (Islamabad Electric Supply Company) distributes electricity across Islamabad and parts of Punjab, including Rawalpindi, Attock, Jhelum, and Chakwal.
Instead of manually working through tariff slabs, fixed charges, and taxes, you simply enter your units (kWh) and connection type — domestic, commercial, or industrial — and it returns an estimated total.

Under the hood
How Does IESCO Bill Calculation Work?
Your bill isn't just "units × rate." It combines several components, regulated by NEPRA (National Electric Power Regulatory Authority).
Units consumed
Based on your meter reading for the billing cycle.
Tariff rate
NEPRA-set per-unit rates that rise as your consumption slab increases.
Fixed charges
Covers meter rent and service costs, regardless of usage.
GST
A percentage tax applied on energy charges.
TV fee
A fixed monthly charge collected on behalf of PTV.
Fuel Price Adjustment
Added or reduced based on actual fuel cost that month — why bills fluctuate even with similar usage.
Domestic slabs
IESCO Tariff Slabs Explained
Tariffs are slab-based — the more you consume, the higher the rate on additional units, similar to income tax brackets. Protected consumers (lower-consumption households) are charged subsidized rates, while non-protected consumers pay standard, higher rates once consumption crosses the protected threshold. Commercial and industrial connections generally carry higher tariffs and fixed charges than domestic ones.
| Domestic units (per month) | Illustrative rate per unit |
|---|---|
| 1 – 50 units | Rs. 9.00 / unit |
| 51 – 100 units | Rs. 12.50 / unit |
| 101 – 200 units | Rs. 16.75 / unit |
| 201 – 300 units | Rs. 21.40 / unit |
| 301 – 700 units | Rs. 27.60 / unit |
| Above 700 units | Rs. 34.20 / unit |
Rates shown are illustrative for this calculator and change periodically per NEPRA notifications — always confirm the latest slab rates via IESCO's official tariff notice.
Managing your usage
What Increases Your Bill — and How to Reduce It
What pushes your bill up
- Higher overall consumption pushing you into a higher slab
- AC usage, especially in summer
- Peak-hour usage on time-of-use connections
- Old, inefficient appliances
- Seasonal fuel adjustment increases
How to bring it down
- Set AC to 26°C or higher
- Use inverter appliances where possible
- Shift heavy appliance use away from peak hours
- Switch to LED bulbs and unplug standby devices
- Service AC and fridge regularly
- Consider solar/net metering if bills stay consistently high
- Track your own meter monthly to catch errors early

Stay ahead of your electricity expenses
An IESCO bill calculator helps you stay ahead of your electricity expenses instead of being surprised each month. Understanding how units, slabs, taxes, and fuel adjustments combine gives you real control over your consumption and costs — but always cross-check with your official IESCO bill, since tariffs are updated periodically by NEPRA.
