🔒 Your files never leave your device.
Slab rates (Rs/unit — editable)
Base tariff per S.R.O. 279(I)/2026. Rates are editable because upper-slab figures can vary slightly between DISCO publications.
How to use
- Read the units consumed from your meter or last bill and type them in.
- Select your consumer category — Non-protected, Protected or Lifeline — and adjust GST or FPA only if you know your latest figures.
- Press Calculate to see the slab-wise breakdown and the estimated total.
How it works
The bill is progressive: the first block of units is charged at the lowest rate, the next block at a higher rate, and so on — you never pay the top rate on all units. This calculator uses the base tariff per S.R.O. 279(I)/2026, before FPA (Fuel Price Adjustment), quarterly adjustments and fixed charges, so it is an estimate only and your DISCO bill (LESCO, IESCO, K-Electric and others) is final. Protected consumers lose protected status above 200 units, and lifeline rates stop applying above 100 units; the calculator applies those rules automatically and tells you when it does.
Worked example: Example: 350 units, Non-protected = 100 × Rs 22.44 + 100 × Rs 28.91 + 100 × Rs 33.10 + 50 × Rs 37.99 = Rs 10,344.50 base; plus 18% GST = Rs 12,206.51, about Rs 12,207.
Frequently asked questions
How is a bijli bill calculated in Pakistan?
Your units are split into slabs. Each slab is charged at its own rate, the amounts are added, extra charges such as FPA are added, and then 18% GST is applied on the total.
What is the difference between protected and non-protected consumers?
Protected consumers use 200 units or less over the qualifying period and pay much lower slab rates. If consumption goes above 200 units, protected status is lost and all units are charged at non-protected rates.
What is FPA in an electricity bill?
FPA is Fuel Price Adjustment — a monthly per-unit charge (sometimes a refund) that passes fuel cost changes to consumers. It changes month to month, so it is an editable field here and defaults to zero.
Why is my real bill different from this estimate?
The real bill can include FPA, quarterly tariff adjustments, fixed charges, meter rent, TV fee and arrears, which vary by month and DISCO. This tool estimates from the base tariff per S.R.O. 279(I)/2026 only.
Does this work for LESCO, IESCO and K-Electric?
Yes — the same notified national tariff structure applies across DISCOs, though small publication differences can occur, which is why the slab rates on this page are editable.
