Electricity bill calculator

Type in your units and see what the bill comes to at the rates NEPRA has notified, including the fuel and quarterly adjustments on October 2026 bills. It shows every line, and how much you would save by finishing the month one slab lower.

Everyone else below 5 kW.

Printed on the bill. Most homes are 1 to 4 kW; 5 kW and above is billed Time-of-Use, use the MDI calculator.

Estimated bill before taxesRs 11,118300 units · about Rs 37.06 per unit all-in
Energy charge (201–300 units at Rs 33.10/unit)Rs 9,930
Fixed charge (Rs 350/kW on 2 kW)Rs 700
Fuel cost adjustment (+Rs 1.1086/unit)Rs 333
Quarterly adjustment (+Rs 0.5194/unit)Rs 156

Cut 100 units to 200 and the whole month reprices in the lower slab: about Rs 4,411 less.

100 more units would cross into the next slab.

Taxes, electricity duty, the PTV fee and any arrears are added on the real bill and depend on your province and category. Rates: NEPRA S.R.O. 279(I)/2026. This is an estimate, not a bill.

How the estimate is built

  1. Energy charge. Your units at the rate of the slab the month reaches. For protected consumers, the previous slab is charged at its own lower rate; unprotected consumers get no such benefit, so the whole month reprices at a boundary.
  2. Fixed charge. A rupees-per-kilowatt figure for your slab, multiplied by your sanctioned load. Lifeline consumers pay a minimum charge instead.
  3. Fuel cost adjustment. This month's per-unit figure on every unit, unless you are lifeline or prepaid. See this month's adjustments.
  4. Quarterly adjustment. The per-unit figure in force for the current three-month window, with the same exemptions.

Taxes come after all of that on the real bill, and they vary: GST, electricity duty set by each province, the PTV licence fee, and advance income tax on larger bills. Our annotated sample bill shows where each sits.

The slab rates behind the numbers

Unprotected domestic, below 5 kW, per S.R.O. 279(I)/2026:

SlabRate per unitFixed charge
1–100 unitsRs 22.44Rs 275/kW
101–200 unitsRs 28.91Rs 300/kW
201–300 unitsRs 33.10Rs 350/kW
301–400 unitsRs 36.46Rs 400/kW
401–500 unitsRs 38.95Rs 500/kW
501–600 unitsRs 40.22Rs 675/kW
601–700 unitsRs 41.85Rs 675/kW
Above 700 unitsRs 47.20Rs 675/kW

Protected and lifeline rates, Time-of-Use and prepaid rates, and the notification itself are on the tariff page.

Three things the calculator makes obvious

  • The 200-unit line is the expensive one. At 200 units an unprotected consumer pays Rs 28.91 a unit; at 201 the month reprices at Rs 33.10. That is roughly Rs 870 for one unit.
  • Protected status is worth more than any appliance change. The same 200 units cost a protected consumer less than half.
  • Adjustments move the bill every month. A positive fuel adjustment of a rupee on 400 units is Rs 400 before tax, on top of everything else.

Frequently asked questions

Why is the whole bill higher when I use a few more units?
Because domestic billing is not slab by slab for unprotected consumers. Cross a slab boundary and every unit in the month is charged at the higher slab's rate. The calculator shows the saving from staying under the boundary for exactly this reason.
Does this work for LESCO, PESCO, MEPCO and the others?
Yes. NEPRA notifies one domestic tariff for every mainland distribution company, so the per-unit rates are the same whichever DISCO bills you. Only Azad Kashmir is notified separately.
Why does the estimate differ from my actual bill?
The real bill adds GST, electricity duty, the PTV fee, income tax where it applies, meter rent and any arrears, none of which the calculator can know. It also uses this month's adjustments; an older bill carried different ones.
What is the sanctioned load and where do I find it?
The connection size in kilowatts that your DISCO approved, printed on the bill. The fixed charge is this figure multiplied by the rate for your slab.
How do I know if I am protected?
A protected consumer used 200 units or fewer in each of the last 6 months and has a sanctioned load below 5 kW. The protected consumer checker works it out from your readings.
