 How to Manually Calculate Your LESCO Bill?

At home, you can estimate your Lahore Electric Supply Company electricity bill by following these precise steps:

  • Check Units Consumed: Note the total units (kWh) used for this month by finding differences between current and previous month meter reading.
  •  Identify Your Consumer Category whether Protected or Unprotected consumer. 
  • Apply the Step-Up Slab Rates: LESCO does not charge a flat rate. If you consume 250 units, the first 100 are charged at the base rate, the next 100 at the second slab rate, and the final 50 at the third slab rate. Always use the latest NEPRA-approved tariff table for accuracy.
  • Multiply Units Γ— Unit Rate, for example: if you used 150 units and your slab rate is Rs. 28.91, multiply total units by the applicable rate to estimate the base electricity cost.
  • Add Taxes and Charges: Including GST, FPA (Fuel Price Adjustment), QTA, TR (Tariff Rationalization), TV Fee, F.C. Surcharge, ED, PYA, and other government charges mentioned on your previous bill.
  • Compare your estimate with your official bill to check whether it is correct.

Simple Formula

Estimated Bill=(UnitsΓ—Unit Rate)+Taxes+Arrears

 Quick Example

If your home used 227 units, and the bill includes taxes plus FPA, your final amount may be much higher than only unit charges. That is why checking only units is not enough.

  • If it is false, contact them at their official helpline number, Central Monitoring Cell or visit your local Sub-Division Office for a correction before the due date.

Current LESCO Tariff and Slab Rates:

You can manage your utility cost by knowing your Tariff Category. In 2026, Lahore Electric Supply Company LESCO streamlined these into Residential, Commercial, and Industrial slabs to reflect current global fuel price adjustments (FPA) and domestic energy subsidies. Before calculating your bill, identify your consumer category.

Domestic Consumers – A-1:

Residential tariff is divided into Protected and Unprotected Consumers based on monthly electricity usage and previous billing history.

If your monthly usage stays within 200 units for the last six months, you get subsidized rates, designed for low-income households with minimal appliance usage.

Units SlabUnit Rate (Rs.)
01 – 50 (Lifeline) 3.95
51 – 100 (Lifeline) 7.74
01 – 100 10.54
101 – 200 13.01

Once your usage crosses 200 units even once in a six-month cycle, you enter standard domestic tariffs where government subsidy reduces, and per-unit cost rises significantly.
