Electricity Bill & Units Calculator Pakistan

Enter your units, your two meter readings or your appliances, then choose protected, unprotected or lifeline. You get the energy charge and fixed charge under the 2026 residential tariff (S.R.O. 279(I)/2026), the slab you land in and a warning when a few extra units push you into a dearer slab. Taxes and fuel adjustments come on top.

Residential electricity tariff (below 5 kW)

Rates notified for all distribution companies in S.R.O. 279(I)/2026 (NEPRA decision of 11 February 2026), as published in IESCO's tariff guide. Variable charge per unit, plus a fixed charge per kilowatt of sanctioned load each month.

Lifeline	Up to 50	3.95	-
Lifeline	1 - 100	7.74	-
Protected	1 - 100	10.54	200

Worked example: 150 units

Protected, 1 kW load. Protected homes keep the benefit of the previous slab:

first 100 units × 10.54 = 1,054.00 next 50 units × 13.01 = 650.50 fixed 1 kW × 300 = 300.00 estimate = Rs 2,004.50

Unprotected, 2 kW load. All units are charged at the rate of the slab you land in:

150 units × 28.91 = 4,336.50 fixed 2 kW × 300 = 600.00 estimate = Rs 4,936.50

Why one extra unit can cost so much

For unprotected homes the whole month is charged at the rate of the slab your total lands in. At 2 kW, 200 units cost 200 × 28.91 + 600 = Rs 6,382, but 201 units cost 201 × 33.10 + 700 = Rs 7,353.10 - almost a thousand rupees more for one unit.

Protected status matters even more: a home that uses 200 units or fewer in each of the last six months pays the much lower protected rates. Go over 200 units in one month and that month is billed at unprotected rates, and protected status is only regained after six months at or under 200.

Units from appliances

One unit is one kilowatt-hour: 1,000 watts for one hour. Units = watts × hours a day × days ÷ 1,000. A 1,500 W air conditioner for 8 hours a day for 30 days uses 1,500 × 8 × 30 ÷ 1,000 = 360 units.

Frequently asked questions

What is the per unit price of electricity in Pakistan in 2026?

Under S.R.O. 279(I)/2026 the residential rate for unprotected homes runs from Rs 22.44 a unit (up to 100 units) to Rs 47.20 (above 700 units). Protected homes pay Rs 10.54 for the first 100 units and Rs 13.01 for 101-200. Fixed charges, fuel adjustments and taxes are added on top.

What is a protected electricity consumer?

A residential consumer who has used 200 units or fewer in each of the last six months. Protected homes pay much lower rates and keep the benefit of the previous slab.

How much is the bill for 200 units?

Before taxes and adjustments: an unprotected home with 2 kW sanctioned load pays 200 × 28.91 = Rs 5,782 plus Rs 600 fixed charge, Rs 6,382. A protected home with 1 kW pays 100 × 10.54 + 100 × 13.01 = Rs 2,355 plus Rs 300, Rs 2,655.

How do I calculate units from my meter?

Subtract last month's reading from this month's. If the meter read 12,450 last month and 12,600 now, you used 150 units.

How many units does a 1.5 ton AC use?

A 1.5 ton AC drawing about 1,500 watts uses 1.5 units an hour, so 8 hours a day for 30 days is about 360 units. Inverter models use less once the room is cool.

Why is my actual bill higher than this estimate?

The bill adds items this estimate leaves out: the monthly fuel price adjustment, quarterly adjustments, sales tax, electricity duty and other charges. Use this to compare slabs and plan usage, and your bill for the final amount.

What this calculator does not do

It estimates the energy and fixed charges only - not fuel or quarterly adjustments, sales tax, income tax, electricity duty or TV fee.
It covers residential connections below 5 kW; time-of-use and commercial tariffs are different.
Rates change when NEPRA notifies a new tariff; the date of the rates used is shown on this page.
K-Electric customers in Karachi are billed by K-Electric; check your own bill for any differences.
