A 300 unit electricity bill in Pakistan comes to about Rs 14,787 on September 2026 rates, for an unprotected home with a 2 kW load. That works out at Rs 49.29 per unit.
At 300 units no home is protected, because protected rates stop at 200. The figure is the same for every company, including K-Electric in Karachi.

All 300 units are billed at the 201 to 300 slab rate of Rs 33.10.

| Fixed charges | 2 kW × 350 | 700.00 |
| Fuel adjustment | 300 × 2.0581 | 617.43 |

How load and duty change it
| Situation | Estimated bill |
|---|---|
| 2 kW, duty charged | Rs 14,787.04 |
| 2 kW, no duty line on bill | Rs 14,599.26 |
| 1 kW, duty charged | Rs 14,374.04 |
| 3 kW, duty charged | Rs 15,200.04 |
Fixed charges are Rs 350 per kW at this slab, so each extra kW of sanctioned load adds Rs 350 plus GST. Some Punjab homes may no longer see electricity duty after a 2025 provincial law, but bills in 2026 have still shown it. Check yours.
What unit 301 costs
At 301 units, every unit moves to Rs 36.46 and the fixed charge rises to Rs 400 per kW.
- 300 units: Rs 14,787.04
- 301 units: Rs 16,162.88
That one unit adds Rs 1,375.84 to the bill. The 400 units bill shows the next slab in full.
Figures assume a 2 kW sanctioned load, electricity duty of 1.5% and no meter rent, at the adjustments on September 2026 bills. They are estimates, not an official bill. Arrears, late payment surcharge and your own load change the amount, so pay what your bill says.
