Key in your IESCO units and sanctioned load. With the current adjustments, 200 units cost an unprotected 2 kW home about Rs 9,088, while a protected home pays about Rs 4,322 for the same units. The issued IESCO bill itself is on PITC's web bill page, found with your 14 digit reference number (steps below).
IESCO is the Islamabad Electric Supply Company. It serves Islamabad, Rawalpindi, Attock, Jhelum and Chakwal. Its area spans the federal capital and parts of Punjab, which matters for electricity duty.
How to check your IESCO bill online
The calculator here works out what a bill should be. It does not look up the bill IESCO has sent. For the issued bill, use the IESCO web bill page of the Power Information Technology Company (PITC):
- Select Reference No and enter the 14 digit reference number from an IESCO bill for the meter. Searching by Customer ID also works.
- Choose U or R, the letter printed after the reference number, and press Search.
- Note the units consumed and the amount due, and print the bill if you need a copy.
Once you have the units, enter them above with your sanctioned load. A large gap between the issued bill and the estimate usually comes from a reading taken over more days than usual, or a different FPA.
IESCO unit price
IESCO uses the national uniform tariff. Protected homes pay Rs 10.54 and Rs 13.01 per unit. Unprotected homes pay Rs 22.44 up to 100 units, Rs 28.91 from 101 to 200, Rs 33.10 from 201 to 300, and more above that.
Unprotected homes pay one rate on all units. So an IESCO home at 200 units pays Rs 28.91 on every unit, and at 201 units pays Rs 33.10 on every unit. See all slabs on the electricity unit price page.
Worked example: 200 units, unprotected, 2 kW
| Line | Working | Amount |
|---|---|---|
| Cost of electricity | 200 × 28.91 | Rs 5,782.00 |
| Fixed charges | 2.0 kW × Rs 300 | Rs 600.00 |
| FC surcharge | 200 × 3.23 | Rs 646.00 |
| Quarterly adjustment | 200 × 0.5194 | Rs 103.88 |
| Fuel adjustment | 200 × 2.3673 | Rs 473.46 |
| Electricity charges | Rs 7,605.34 | |
| Electricity duty | 1.5% of cost of electricity and QTA | Rs 88.29 |
| GST | 18% of the charges above and duty, rounded | Rs 1,300.00 |
| Duty on fuel adjustment | 1.5% of the fuel adjustment | Rs 7.10 |
| GST on fuel adjustment | 18% of the fuel adjustment and its duty, rounded | Rs 87.00 |
| Government charges | Rs 1,482.39 | |
| Total | Rs 9,087.73 |
Now compare the neighbours:
- Protected at 200 units: Rs 4,322.32. The protected home pays less than half.
- Unprotected at 201 units: Rs 10,255.06. One extra unit adds more than Rs 1,000, because all 201 units move to the Rs 33.10 slab and fixed charges rise from Rs 300 to Rs 350 per kW.
If your bill is close to 200, the last few units are the most expensive units you will use all month.
Pay after the due date and a late payment surcharge is added: 5% of Rs 7,132.15 (the electricity charges without the fuel adjustment and taxes) for the first 3 days, so Rs 9,445, then 10%, so Rs 9,801.
Electricity duty in Islamabad and Rawalpindi
Electricity duty is a provincial levy. Historically it was 1.5% on homes in both Islamabad and Punjab. In July 2025 the federal Power Division said it would stop collecting duty through bills, and Punjab later exempted homes by law.
Some IESCO bills still carry the duty, so go by your own bill. If there is no "electricity duty" line, untick the duty box in the calculator. At 200 units the bill without duty is Rs 8,974.34.
Reading your IESCO bill
Use the monthly units consumed, not the running meter reading. Your sanctioned load in kW is shown with the connection details. If the bill lists the FPA and QTA per unit, copy them into the adjustment boxes for a closer match.
If your bill covers more days than usual, the units will be higher and may push you into the next slab. That is a meter reading issue, not a tariff change.
If you are on the edge of IESCO's area, the GEPCO bill calculator and the PESCO bill calculator apply the same national rates.
IESCO bill by units
Unprotected IESCO connection, 2 kW sanctioned load, with the current adjustment rates and electricity duty.
| Units | Cost of electricity | Estimated total bill |
|---|---|---|
| 100 100 units bill | Rs 2,244 | Rs 4,064 |
| 150 150 units bill | Rs 4,337 | Rs 6,993 |
| 200 200 units bill | Rs 5,782 | Rs 9,088 |
| 250 250 units bill | Rs 8,275 | Rs 12,554 |
| 300 300 units bill | Rs 9,930 | Rs 14,900 |
| 400 400 units bill | Rs 14,584 | Rs 21,319 |
| 500 500 units bill | Rs 19,475 | Rs 30,250 |
This calculator is not run by IESCO or NEPRA. It leaves out arrears and instalments, and assumes a normal billing period, so the amount on your printed IESCO bill is the one that counts. The late payment amounts are shown under the estimate.
Questions people ask
Where can I see my IESCO bill online?
On the IESCO web bill page of PITC (Power Information Technology Company). Enter the 14 digit reference number or your Customer ID, choose U or R as printed after the number, and search. Our calculator does not show issued bills; type the units from that bill above to check how the amount was reached.
What is the IESCO unit price?
IESCO homes pay the February 2026 NEPRA rates: Rs 10.54 and Rs 13.01 for protected users, and Rs 22.44 to Rs 47.20 for unprotected users. With the current adjustments and taxes, an unprotected 200 unit bill works out at about Rs 45 per unit.
How much is a 200 unit IESCO bill?
About Rs 9,088 for an unprotected home with 2 kW load, and about Rs 4,322 for a protected home, with the current adjustments with duty included. The protected figure applies only if every one of your last six bills was 200 units or less.
Do Islamabad homes pay electricity duty?
It depends on your bill. The federal government announced in July 2025 that duty would no longer be collected through bills, but 2026 bills in the region have still shown it. Your own bill is the only reliable guide, so match the duty box to it.
Is the IESCO tariff the same as LESCO?
Yes. Since February 2026 all government distribution companies and K-Electric charge one uniform tariff. The LESCO bill calculator and this one give the same answer for the same inputs.
