Who is a protected consumer?

A domestic consumer whose usage has stayed below 200 units for the past 6 consecutive months. Protected consumers get significantly lower tariffs.

Does this match my WAPDA or K-Electric bill exactly?

It will be very close. Small differences come from monthly fuel adjustments, late payment surcharges, or arrears that vary per consumer.

How can I lower my bill?

Stay under 200 units if possible, switch to LED bulbs and inverter appliances, unplug idle electronics, and avoid heavy load during peak hours (6 PM to 10 PM).

Are commercial and industrial tariffs covered?

The calculator focuses on domestic tariffs. Commercial and industrial rates use a different structure with peak/off-peak time-of-use pricing.

How it works

Pakistani DISCOs (LESCO, GEPCO, MEPCO, IESCO, FESCO, PESCO, HESCO, SEPCO, QESCO) bill domestic users using NEPRA's progressive slab tariff (B-1). Each unit is charged at the rate of the slab it falls into; FPA, QTR, ED, GST and TV fee are added on top.

Energy   = Σ (units_in_slab × slab_rate)
FPA      = units × FPA_rate
QTR      = units × QTR_rate
Subtotal = Energy + FPA + QTR + Fixed
ED       = Subtotal × ED%
GST      = Subtotal × GST%   (0% for Lifeline / Protected)
Bill     = Subtotal + ED + GST + TV_fee

Your input:
  Type     = unprotected
  Units    = 350
  Energy   = PKR 10,345
  FPA      = PKR 875
  QTR      = PKR 0
  Fixed    = PKR 0
  ED       = PKR 168
  GST      = PKR 2,020
  TV fee   = PKR 35
  Total    = PKR 13,442

Lifeline — ≤100 units/month, lowest rates, no GST.
Protected — ≤200 units/month for 6 consecutive months, no GST.
Unprotected — >200 units/month, higher rates + 18% GST.

FPA and QTR change every month — check the line items on your previous bill and adjust them above for the most accurate estimate. K-Electric uses a separate tariff and is not covered.

Overview

What is the Electricity Bill Calculator?

The Electricity Bill Calculator estimates your monthly WAPDA or K-Electric bill based on the units consumed. It uses the current NEPRA slab tariffs and shows energy charges, taxes, and the final amount payable.

Use it before the bill arrives to plan your budget, understand which slab you are in, and see how reducing a few units could save thousands of rupees over the year.

Step-by-step

How to use this calculator

1Enter the number of units (kWh) you have consumed this month.
2Choose your consumer type (domestic, commercial) if the option is shown.
3Select whether you are a protected consumer (under 200 units for the last 6 months).
4Click Calculate to see slab-wise energy charges, taxes, and your total bill.

Methodology

How it works

Pakistan uses slab-based tariffs for domestic consumers. The first 100 units are charged at the lowest rate, the next slab at a higher rate, and so on. Once you cross 200 or 300 units, the higher rate applies to ALL units, not just the portion above — this is why bills jump sharply.

The calculator applies the correct slab rate to your consumption, then adds fixed components like fuel price adjustment, electricity duty, GST, TV fee, and financing cost surcharge based on standard published rates.

Actual bills can differ slightly month-to-month because of monthly fuel adjustments announced by NEPRA.
