Pakistan Electricity Slab Rates — Reference Table
NEPRA sets electricity tariffs in progressive slabs — higher consumption means a higher per-unit rate. The base slab rate is only part of your bill; FPA, QTA, GST, and surcharges add 40-60% on top.
| Slab (Units/Month) | Base Rate (Rs/kWh) | Consumer Type | Effective Cost* |
|---|---|---|---|
| 0–100 | Rs. 8–12 | Protected / lifeline | Rs. 15–20 with taxes |
| 101–200 | Rs. 16–20 | Protected residential | Rs. 25–32 |
| 201–300 | Rs. 22–27 | Non-protected | Rs. 35–42 |
| 301–700 | Rs. 30–38 | Non-protected | Rs. 45–55 |
| 700+ | Rs. 38–45 | Non-protected (highest) | Rs. 55–65+ |
*Effective cost includes estimated FPA (Rs. 2-3/unit), QTA, 17% GST, and surcharges. Exact amounts change monthly based on NEPRA determinations.

Worked Examples — What Real Bills Look Like
These examples show how the same slab system produces dramatically different bills at different consumption levels. The non-linear jump when crossing slab boundaries is what surprises most consumers.
| Scenario | Units | Base Charge | FPA + QTA | GST (17%) | Total Bill |
|---|---|---|---|---|---|
| Small household (fans + lights) | 150 | Rs. 2,700 | Rs. 375 | Rs. 460 | ~Rs. 3,500 |
| Average home (1 AC, 4 hrs/day) | 350 | Rs. 10,500 | Rs. 875 | Rs. 1,785 | ~Rs. 13,200 |
| Large home (2 ACs, 8 hrs) | 700 | Rs. 24,500 | Rs. 1,750 | Rs. 4,165 | ~Rs. 30,400 |
How the Calculation Works
Your electricity bill is built from five layers stacked on top of each other. The base energy charge uses the slab rate for your consumption level. FPA (Fuel Price Adjustment) adds Rs. 2-5 per unit depending on the month's actual fuel costs. QTA (Quarterly Tariff Adjustment) adds another Rs. 0.50-3 per unit for non-fuel generation costs. GST at 17% is calculated on the total of base + FPA + QTA. Finally, fixed charges (meter rent, TV fee, surcharges) add Rs. 200-500 regardless of consumption.
The critical insight: crossing the 200-unit boundary switches you from protected to non-protected consumer status, which can increase your per-unit rate by 40-60% on ALL units — not just the units above 200. This cliff effect is why a household consuming 199 units might pay Rs. 3,500 while one consuming 210 units pays Rs. 5,500.
Estimates only. Actual bills vary by DISCO, month (FPA changes monthly), and applicable surcharges. This calculator uses average rates — verify with the unit cost calculator using your actual bill for precise per-unit costs.
Tips for Reducing Your Electricity Bill
- Stay below 200 units to remain in the protected consumer category — the single biggest cost lever
- Switch to inverter AC — uses 30-40% less electricity than non-inverter models for the same cooling
- LED lighting throughout — replacing 10 old bulbs saves 40-80 units monthly
- Consider solar — even a small 3 kW system drops your grid consumption by 200-300 units. Calculate savings: solar savings calculator
Electricity Bill Calculator — Common Questions
Within 10-15% of actual bills for most consumers. The main variable is FPA, which changes monthly. For exact figures, check your DISCO portal (LESCO, MEPCO, FESCO) or calculate your actual per-unit cost using the unit cost calculator.
The calculator uses average FPA/QTA rates. In months with high fuel costs (summer 2024-25 saw FPA of Rs. 4-5/unit), actual bills run 15-25% above estimates. Additional charges like meter rent, TV fee, and previous arrears also increase the total.
The 0-100 unit slab for protected consumers has the lowest rate — approximately Rs. 8-12 per unit before taxes. With all charges, effective cost is Rs. 15-20 per unit. This lifeline tariff is subsidized by the government.
Your slab is determined by total units consumed in one billing cycle (typically 30 days). Check "Units Consumed" on your bill. Under 200 = protected; over 200 = non-protected with higher rates. See complete slab system guide.
Base slab rates set by NEPRA are the same across all DISCOs (LESCO, MEPCO, FESCO, IESCO, etc.). However, some provincial taxes and surcharges vary slightly by region, causing minor differences in the final bill amount.
