IESCO Bill Calculator Example: 300 Units Line by Line
Here is the same 300-unit bill as a IESCO bill calculator works it out, in the order the lines appear on a IESCO bill:
| Bill line | Amount |
|---|---|
| Cost of electricity | Rs 9,930.00 |
| Fixed charges | Rs 700.00 |
| FC surcharge | Rs 969.00 |
| Fuel price adjustment (Rs 1.1086) | Rs 332.58 |
| Quarterly adjustment (Rs 0.5194) | Rs 155.82 |
| Electricity duty 1.5% | Rs 156.28 |
| GST 18% | Rs 2,204 |
| Total payable | Rs 14,448 |
| After due date | Rs 15,657 |
- Cost of electricity = 300 × Rs 33.10 (201-300 slab) = Rs 9,930.
- Fixed charges = 2 kW × Rs 350 = Rs 700.
- FC surcharge = 300 × Rs 3.23 = Rs 969.
- FPA and QTA = 300 × Rs 1.1086 and 300 × Rs 0.5194.
- Electricity duty = 1.5% of electricity cost plus FPA and QTA.
- GST = 18% of everything above. Total = Rs 14,448.
IESCO Slab Rates 2026
IESCO does not set its own prices. Like every government DISCO it charges the uniform NEPRA tariff from S.R.O. 279(I)/2026:
| Slab | Rate per unit | Fixed charge |
|---|---|---|
| Protected 1-100 | Rs 10.54 | Rs 200 per kW |
| Protected 101-200 | Rs 13.01 | Rs 300 per kW |
| Unprotected 1-100 | Rs 22.44 | Rs 275 per kW |
| Unprotected 101-200 | Rs 28.91 | Rs 300 per kW |
| Unprotected 201-300 | Rs 33.10 | Rs 350 per kW |
| Unprotected 301-400 | Rs 36.46 | Rs 400 per kW |
| Unprotected 401-500 | Rs 38.95 | Rs 500 per kW |
| Unprotected 501-600 | Rs 40.22 | Rs 675 per kW |
| Unprotected 601-700 | Rs 41.85 | Rs 675 per kW |
| Unprotected Above 700 | Rs 47.20 | Rs 675 per kW |
| Time of Use (5 kW+) | Peak Rs 46.85 / off-peak Rs 34.53 | Rs 675 per kW on 50% of load or MDI |
Protected homes (200 units or less for six months) pay much less: a 150-unit protected IESCO bill on 1 kW is about Rs 2,764 against Rs 6,412 unprotected. Read protected and unprotected consumers explained.
Non-Filer Example: 450 Units
A non-filer using 450 units on 2 kW pays Rs 24,766, which includes Rs 0 income tax under section 235 because the bill crossed Rs 25,000. A filer on the Active Taxpayers List pays Rs 24,766 for the same units.
How to Check Your Bill With a IESCO Bill Calculator
A IESCO bill calculator is only as good as the numbers you put in. Take these from your printed bill:
- Download your bill from the IESCO website or the PITC bill portal using the 14-digit reference number.
- Check the “Protected” or “Un-Protected” label and your 12-month units history on the bill.
- Compare the “units consumed”, “sanctioned load” and “FPA” figures with the Electricity Bill Calculator. If the total is far off, look for arrears, meter rent or a detection bill.
Tips to Cut Your IESCO Bill
Run a few what-if numbers in the IESCO bill calculator before the next reading. These steps make the biggest difference:
- Keep below 200 units for six months to become protected.
- Watch the 300 and 400 unit boundaries: one extra unit changes the rate on every unit.
- Pay before the due date to avoid the 10% late payment surcharge.
- Reduce your sanctioned load if it is higher than you need, because fixed charges are per kW.
- See the full list of electricity per unit prices in Pakistan for every slab.
