TESCO Bill Calculator 2026 | Accurate Unit Estimator

The TESCO Bill Calculator estimates your monthly electricity bill for connections in Khyber, Bajaur, Mohmand, Kurram, Orakzai, and Waziristan based on current NEPRA-notified tariff slabs. Enter your consumed units (kWh) below to see an instant breakdown of your base energy cost, Fuel Price Adjustment (FPA), FC Surcharge, Electricity Duty, and applicable taxes.

How TESCO Electricity Bills Are Calculated

Your monthly power bill issued by the Tribal Areas Electricity Supply Company is not a flat multiplication of units. It uses progressive slab billing combined with government surcharges and regulatory taxes.

Total Bill = Base Energy Cost + Fixed Charges + FPA + FC Surcharge + Electricity Duty (1.5%) + GST (18%) + TV Fee (Rs. 35)

If you have your paper slip or reference number ready, you can view your latest TESCO duplicate bill online to verify your previous 6-month unit history before calculating.

1. Protected vs. Unprotected Consumer Status

NEPRA divides residential consumers into two distinct categories:

• Protected Consumers: Domestic users consuming 200 units or fewer per month consecutively for the past six months. Protected users pay subsidized base rates starting at Rs. 3.95/unit and are exempt from standard General Sales Tax (GST).
• Unprotected Consumers: Users who exceed 200 units in any single billing cycle. Once unprotected, higher base rates apply across all progressive tiers, along with standard sales tax and fixed monthly charges.

3. Understanding Taxes, Surcharges & Extra Fees

Beyond raw unit consumption, every TESCO statement includes mandatory line items:

1. Fuel Price Adjustment (FPA): The difference between estimated generation fuel costs and actual imported fuel prices (oil, LNG, coal). It fluctuates monthly under NEPRA notifications.
2. Debt Service Surcharge (DSS):** A uniform levy of Rs. 3.23 per kWh applied to every unit consumed across Pakistan to service power sector liabilities.
3. Electricity Duty (ED): A 1.5% tax calculated directly on your total base energy charges.
4. General Sales Tax (GST): An 18% federal tax applied to the sum of base energy charges, FPA, and FC surcharge for unprotected connections.
5. TV License Fee: A flat charge of Rs. 35 for domestic connections and Rs. 60 for commercial premises.

If you are setting up a separate meter for a shop or agricultural tubewell in the tribal divisions, review the TESCO new meter connection process to confirm the required commercial load limits and testing fees.

Step-by-Step Calculation Example

For an Unprotected Domestic Connection using 250 units:

1. Base Energy:
   - First 100 units @ Rs. 16.48   = Rs. 1,648.00
   - Next 100 units  @ Rs. 22.95   = Rs. 2,295.00
   - Next 50 units   @ Rs. 27.14   = Rs. 1,357.00
   ─────────────────────────────────────────────
   Subtotal Base Energy            = Rs. 5,300.00

2. Surcharges & Taxes:
   - FPA (250 × Rs. 3.50 est.)     = Rs. 875.00
   - DSS (250 × Rs. 3.23) = Rs. 807.50
   - Electricity Duty (1.5%)       = Rs. 79.50
   - GST (18% on Energy + FPA + FC)= Rs. 1,256.85
   - Fixed Charges (≤300 units)    = Rs. 0.00
   - TV Fee                        = Rs. 35.00
   ─────────────────────────────────────────────
   Total Estimated Bill            = Rs. 8,353
