Calculating your Gujranwala Electric Power Company (GEPCO) bill manually helps you understand your monthly expenses and avoid surprise charges. Using NEPRA’s regulated tariff rules, you can estimate your exact bill using an online calculator or by working through the formula yourself.
Key Components of a GEPCO Bill
To calculate your total bill, you must combine several components beyond the basic per-unit cost:
- Energy Charges (Variable Cost): Total Units Consumed $\times$ Base Unit Rate (determined by your tariff slab or peak/off-peak rates).
- Fixed Charges: A set monthly fee charged according to your sanctioned load (kW).
- Fuel Cost Adjustment (FCA): A fluctuating monthly charge reflecting thermal fuel price variations.
- Quarterly Tariff Adjustment (QTA): Periodic adjustments applied every three months.
- Government Taxes & Duties:
- General Sales Tax (GST): 18% applied to the subtotal of energy charges and adjustments.
- Electricity Duty (ED): Usually 1.5% of energy charges.
- Financing Cost (F.C.) Surcharge: Applied per unit consumed.
- TV Fee: Fixed at Rs 35 for residential connections (Rs 60 for commercial).
How to Use the GEPCO Online Tariff Calculator
The easiest way to calculate your bill is by using the official GEPCO or PITCO online billing calculator.

- Note Total Consumption: Check your current meter reading against the previous reading to find total units consumed ($kWh$).
- Select Connection & Tariff Type: Open the calculator tool, choose your consumer type, and select whether you have a Single-Phase (Non-TOU) or 3-Phase (TOU) meter.
- Enter Consumption Values:
- For Non-TOU Meters: Enter your total monthly units consumed (e.g., 350 units).
- For TOU Meters: Enter Peak Units and Off-Peak Units in their respective fields.
- Calculate: Click Calculate / Submit. The tool will break down your base energy cost, fuel adjustments, taxes, and final payable amount.
Manual Calculation Example (Non-TOU Residential)
Here is how a 350-unit residential bill is calculated under standard slab rates:
| Consumption Slab | Rate per Unit | Calculation | Base Cost |
| First 100 Units | Rs 15.00 | $100 \times 15.00$ | Rs 1,500 |
| 101 to 200 Units | Rs 22.00 | $100 \times 22.00$ | Rs 2,200 |
| 201 to 300 Units | Rs 33.10 | $100 \times 33.10$ | Rs 3,310 |
| 301 to 350 Units | Rs 37.99 | $50 \times 37.99$ | Rs 1,899.50 |
| Base Energy Cost Subtotal | Rs 8,909.50 |
- Add Taxes & Surcharges (approx. 25–30% additional):
- GST (18%): $\approx \text{Rs } 1,603.71$
- F.C. Surcharge + FCA + Duty + TV Fee: $\approx \text{Rs } 1,500$
- Estimated Final Payable Bill:$\approx \text{Rs } 12,013$
