How the IESCO Bill Calculator Works
The IESCO Bill Calculator uses the same formula and tariff structure as the official IESCO billing system. You simply enter your consumed units, and the calculator applies the relevant tariff according to your consumer type and slab.
Let’s break down how the system calculates your estimated bill step by step.
Step 1: Select Consumer Type
IESCO applies different rates based on consumer categories such as:
- Domestic
- Commercial
- Industrial
- Agricultural
- Single phase or three phase connections
Step 2: Enter Units Consumed
You need to input the total number of units (kWh) consumed in a billing month. This value is usually available on your electricity meter or in the “Units Consumed” section of your previous bill. Use our Electricity Load Calculator in kW for Home
Step 3: Apply Tariff Rate
The calculator applies the per-unit tariff rate as per NEPRA’s latest approved rates. Domestic consumers are charged in slabs, meaning the per-unit price increases with higher usage.
Step 4: Add Taxes and Additional Charges
The IESCO bill also includes various taxes and charges, which are automatically added by the calculator:
- GST (General Sales Tax) – Usually 17% of the electricity cost
- FC Surcharge (Financing Cost) – Fixed per unit charge if any
- Electricity Duty – Charged as a percentage of the energy cost
- TV License Fee – Rs. 35 for domestic, Rs. 60 for commercial users
- Meter Rent – Fixed monthly charge (if applicable)
- FPA – Fuel price adjustment
Step 5: Display Total Bill
After applying all rates and taxes, the calculator displays your total payable amount, including arrears or adjustments if any.

IESCO Bill Estimator — What to Expect This Month
The IESCO Bill Estimator helps consumers get a quick idea of their expected electricity bill based on monthly units, tariff slab, and applicable fixed charges. Since electricity rates vary across residential, commercial, and industrial categories, the estimator provides a more realistic picture by considering your consumption pattern and slab-wise pricing.
This month’s bill may fluctuate due to changes in unit consumption, fuel price adjustments, and slab transitions, especially when usage crosses into higher tariff brackets. Consumers in protected residential categories may still benefit from lower lifeline rates, while unprotected users and higher consumption slabs will see increased per-unit costs.
By using an IESCO bill estimator, you can better plan your electricity usage, avoid unexpected bill spikes, and identify whether shifting consumption to off-peak hours or reducing load can help lower your monthly charges.
