How to use the electricity bill calculator
- 1 Enter the units used this month from your meter or bill.
- 2 Choose protected if you used 200 units or less in each of the last six months.
- 3 Enter the FPA per unit shown on your bill, if any.
- 4 Check the electricity duty rate and add any fixed charges.
Worked example
A non-protected home using 350 units. The first 300 units are charged at Rs 33.10 and the next 50 at Rs 37.99, giving energy charges of about Rs 11,830. Adding 1.5% electricity duty, 18% GST and the Rs 35 TV fee, the bill is about Rs 14,171, roughly Rs 40.49 per unit.
Reading your bill and keeping it down
- Protected status: staying at 200 units or less every month for six months keeps the lowest protected rates. One month above 200 removes them for six months.
- Fuel price adjustment is set monthly by NEPRA and can add or take away several rupees per unit; quarterly adjustments also appear on some bills.
- Biggest users: ACs, electric water heaters, irons and water motors. One 1.5 ton AC can use more units than the rest of the house.
- Check your meter reading and the reading date on the bill; a late reading can push you into a higher slab.

Frequently asked questions
What are the domestic electricity rates in 2026?
For WAPDA DISCOs: protected Rs 10.54 (1-100 units) and Rs 13.01 (101-200). Non-protected: Rs 22.44, 28.91, 33.10, 37.99, 40.22, 41.62 and 42.76 per unit for slabs up to 700 units, and Rs 47.69 above 700.
Who is a protected consumer?
A domestic consumer who used 200 units or less in each of the previous six months. Going above 200 units once removes protected status for six months.
What is the one previous slab benefit?
Non-protected consumers are charged their current slab rate on units in that slab and the previous slab's rate on earlier units, rather than the cheapest rates for every slab.
What is FPA?
Fuel price adjustment, a monthly charge or credit per unit set by NEPRA based on fuel costs. It appears on your bill.
Does this apply to K-Electric?
No. K-Electric customers in Karachi have their own tariff, although rates are broadly similar.
Why is my bill higher than this?
Bills can include fixed charges, quarterly adjustments, arrears, income tax for non-filers above a bill amount and other taxes not shown here.
How can I reduce my bill?
Use inverter ACs, LED lights, run heavy appliances outside peak hours and keep units under 200 if you can.
What are peak hours?
Peak hours are evening hours set by NEPRA; time-of-use meters charge more during them.
Is GST charged on the whole bill?
GST of 18% is charged on energy charges, FPA and some other components.
Why did my bill jump when I crossed 200 units?
Crossing 200 units removes protected status, so the cheaper protected rates no longer apply for six months, and bills can more than double.
Does a solar system remove my bill?
A solar system can cut most energy charges, but fixed charges and taxes on imported units may still apply.
