FESCO Tools
Want to estimate or verify your FESCO bill? This guide explains the FESCO bill calculation formula, current slab-based tariff rates, and additional charges like FPA and GST that affect your final bill amount.
FESCO bill calculation formula
Your FESCO electricity bill is calculated using slab-based tariff rates set by NEPRA (National Electric Power Regulatory Authority). The formula combines per-unit energy charges with fixed fees, taxes, and adjustments.
FESCO bill rates
The following table shows approximate residential tariff rates for FESCO consumers. Actual rates are set by NEPRA and may be revised periodically. Always verify against the latest NEPRA notification.
| Units Range | Category | Approx. Rate / Unit | Note |
|---|---|---|---|
| 1–100 units | Protected / Lifeline | ~PKR 7.74 | Subsidised rate for low-usage consumers |
| 1–100 units | Regular domestic | ~PKR 12.50 | Standard low-slab rate |
| 101–200 units | Slab 2 | ~PKR 15.75 | Moderate usage bracket |
| 201–300 units | Slab 3 | ~PKR 20.10 | Mid-range consumption level |
| 301–500 units | Slab 4 | ~PKR 25.45 | Higher residential usage |
| 501–700 units | Slab 5 | ~PKR 28.00 | Heavy usage — higher per-unit cost |
| 700+ units | Slab 6 | ~PKR 31.80+ | Highest residential slab |
Important: These rates are indicative. For the current notified tariff, refer to the official NEPRA website.
Additional charges
Beyond per-unit energy charges, several additional items appear on your FESCO bill:
| Charge | Explanation |
|---|---|
| FPA (Fuel Price Adjustment) | Monthly adjustment by NEPRA based on fuel cost changes — can increase or decrease the bill |
| GST (General Sales Tax) | Applied as per government rules; rate varies by consumer category |
| Electricity Duty | Provincial levy — typically a small percentage of the energy charge |
| TV Fee | PTV licence fee collected via the electricity bill; currently PKR 35 for most residential connections |
| Fixed Charges | Minimum charges for maintaining the connection, applied even with low usage |
| Meter Rent | Small monthly charge for the electricity meter equipment |
FESCO bill tariff
Commercial and industrial FESCO consumers have different tariff categories including demand charges, connected load fees, and time-of-use billing. These consumers should check the applicable tariff schedule from NEPRA for their specific connection type.
Key differences: commercial rates are generally higher per unit, industrial users may have demand-based charges, and time-of-use metering applies to certain categories.
FAQ
Your FESCO bill is calculated based on units consumed (current minus previous meter reading), applied against slab-based tariff rates set by NEPRA. Additional charges like FPA, GST, electricity duty, and arrears are added to reach the final payable amount.
FPA stands for Fuel Price Adjustment. It is a monthly surcharge or credit applied by NEPRA to reflect changes in fuel costs used for electricity generation. It can increase or decrease your bill.
FESCO bill rates vary by slab. Lower-usage consumers (under 100 units) pay approximately PKR 7–12 per unit, while heavy users (500+ units) may pay PKR 28–32 per unit. Rates are set by NEPRA and subject to periodic revision.
Sudden increases usually happen when your monthly usage crosses into a higher slab, when FPA is higher than usual, when estimated readings are corrected, or when seasonal consumption (e.g., summer ACs) causes a spike.
While there is no official FESCO calculator app, this page provides a step-by-step calculation method. Third-party apps may exist but always verify results against the official tariff schedule.
