If your electricity bill feels higher than the units suggest, the reason is usually the slab system, the monthly fuel price adjustment (FPA) and the taxes stacked on top. Here is how each part works, in plain language.
How unit slabs work
Domestic bills in Pakistan use a slab (tiered) system. The per-unit rate steps up as your monthly usage crosses 100, 200, 300 and higher thresholds, and the higher rate applies only to the units in that upper slab. Lower-usage protected and lifeline consumers pay less per unit than higher-usage unprotected ones.
Approximate domestic tariff
These are the NEPRA uniform rates that apply to the mainland DISCOs (LESCO, MEPCO, FESCO and the rest). We show them only once verified against NEPRA, so the figures below appear as they are confirmed.

A fuel price adjustment (FPA), quarterly adjustments, electricity duty, GST, a TV licence fee and other taxes are added on top of the per-unit energy charge, so the effective rate changes month to month.
What is fuel price adjustment (FPA)?
The FPA is a monthly adjustment that reflects the actual cost of the fuel used to generate electricity, usually two months earlier. When fuel costs rise, the FPA adds to your bill; when they fall, it can be a small credit. It is shown as a separate line and is the single biggest reason two months with the same units can cost different amounts.
Taxes & other charges
On top of the energy charge and FPA, your bill carries electricity duty, GST, a TV licence fee, and sometimes a fixed or minimum charge and a financing-cost surcharge. Together these can add a noticeable amount to the total.
