Understand what “per unit price” really means in Pakistan, why two homes with the same units can pay different bills, and how to use units for a better solar savings estimate.
Reviewed 1 June 2026. This guide explains the tariff structure and estimation method. It is not a replacement for your official DISCO, K-Electric, NEPRA, or Government notification.
Quick Answer
The residential base electricity unit price in Pakistan ranges from about Rs 3.95 per unit for eligible lifeline usage to about Rs 47.69 per unit above 700 units in the official uniform tariff table used for this review. Time-of-use residential rates are listed around Rs 46.85 peak and Rs 40.53 off-peak. Your final payable bill can still be higher because FCA, QTA, taxes, fixed charges, arrears, meter rent, and other line items are added separately.

These are base variable charges from the official tariff reference, shown before final-bill adjustments such as FCA, QTA, GST, other taxes, arrears, and any DISCO/K-Electric billing line items. Use your actual bill as the final source of truth.

Why One Unit Price Can Mislead You

Monthly unitsHigher consumption usually moves the bill into more expensive tariff slabs.Use the units printed on your bill, not only the paid amount.Use monthly units or peak/off-peak units where possible.
Protected or unprotected categoryResidential consumers under 200 units for a consistent period may be treated differently.Look for category wording on your bill before comparing rates.Use monthly units or peak/off-peak units where possible.
Time-of-use meterSome connections use separate peak and off-peak rates instead of one flat unit rate.If your bill has peak and off-peak units, calculate them separately.Use monthly units or peak/off-peak units where possible.
FCA, QTA, taxes, and fixed chargesThese can make the effective per-unit cost higher than the base energy charge.Divide final payable bill by units only when you need an effective estimate.Use monthly units or peak/off-peak units where possible.
How To Estimate Cost From Units
If you only need a quick planning number, divide your final payable bill by your consumed units to get an effective per-unit cost. If you want a better estimate, separate base energy charges from taxes, FCA, QTA, fixed charges, and arrears. For solar planning, monthly units are more useful than the rupee amount because solar offsets imported units first.

A high electricity unit cost can make solar attractive, but the right system size still depends on monthly units, daytime usage, roof space, net-metering or net-billing treatment, and your AC load. Start with units, then compare solar size and payback.
What is the electricity per unit price in Pakistan?
There is no single per-unit price for every household. The applicable cost depends on residential category, monthly units, protected or unprotected status, ToU meter treatment, FCA, QTA, taxes, fixed charges, and arrears.
Why does my bill divided by units look higher than the tariff slab?
The base energy charge is only one part of the bill. Fuel charges adjustment, quarterly adjustment, taxes, fixed charges, and other line items can increase the effective per-unit cost.
Should I use bill amount or units for a solar estimate?
Units are better. Bill amount is useful for a rough estimate, but monthly units and peak/off-peak units give a clearer solar system size and savings estimate.
