About the Electricity Bill Estimator
Pakistani electricity bills are hard to read because the per-unit rate is not one number — it is a ladder of slabs, and then FPA, fixed charges, electricity duty, GST and the TV licence fee are stacked on top. This free electricity bill estimator does that whole calculation: type in the units you consumed and see the bill built up line by line, exactly the way your DISCO builds it.
The slab rates shipped with the tool are indicative domestic rates in the 2025-26 style, and every one of them is editable. If your bill from LESCO, GEPCO, MEPCO, FESCO or any other DISCO shows different rates for your category, change the six slab fields and the estimate follows — the defaults are typical, but your own bill is the truth.
Everything runs inside your browser and nothing is uploaded or stored. Use it to budget before the bill arrives, to sanity-check a bill that looks too high, or to see how much each extra appliance — an AC, a water pump, a second fridge — pushes the total up for the month once the house crosses into a higher tariff slab.
How to Use the Electricity Bill Estimator
Follow these simple steps — the whole process takes under a minute:
- Enter the units consumed — the kWh figure for the month, from your meter (current reading minus previous reading) or from the bill itself.
- Check the six slab rates — the defaults are indicative domestic rates; open your latest bill and replace any rate that differs for your DISCO.
- Add the variable charges — the fuel price adjustment (FPA) per unit if your bill shows one, and the fixed charges from your tariff.
- Set duty, GST and the TV fee — 1.5% duty, 18% GST above 200 units and a Rs. 35 TV fee are typical; enter 0 where they do not apply.
- Press Estimate Bill — read the energy cost of each slab, every add-on charge and the estimated total for the month.
The Formula & Method Behind the Electricity Bill Estimator
The energy cost uses progressive slabs: each slab rate applies only to the units that fall inside that slab, not to the whole consumption. For 250 units at the default rates, the first 100 units cost 100 × 35 = Rs. 3,500, the next 100 cost 100 × 47.50 = Rs. 4,750, and the remaining 50 cost 50 × 55 = Rs. 2,750 — an energy total of Rs. 11,000, not 250 × 55.
The add-on charges are simple multiples. The fuel price adjustment (FPA) is a per-unit charge, so FPA = FPA per unit × total units — it recovers the variation in furnace-oil prices between tariff revisions. Fixed charges are a flat monthly amount. Electricity duty is a percentage of the energy cost, typically 1.5% for domestic consumers.
GST (sales tax) is applied as GST% × (energy cost + FPA + fixed charges + electricity duty), but only when monthly units exceed 200 — at 200 or fewer the estimate treats it as zero, matching the lighter treatment smaller consumers see. The estimated total is energy + FPA + fixed + duty + GST + TV fee. All figures are indicative; your DISCO bill is final.
Reading a Pakistani Electricity Bill — What Each Charge Means
Find the slab table on your bill. Every DISCO bill lists the applicable tariff: rates per unit for each slab and the fixed charges, plus notes on protected or unprotected status. Match the six rates in the calculator to that table once and every future estimate lands close to the real bill.
FPA and quarterly adjustments. The fuel price adjustment changes month to month with furnace-oil costs and can be negative when fuel is cheap; some bills also show quarterly adjustments. Enter the per-unit FPA from your bill above, and add one-off lump-sum adjustments mentally to the final estimate.
Taxes vary by category and DISCO. LESCO, GEPCO, MEPCO, FESCO and the rest follow one national framework, but the printed lines differ — electricity duty, GST, the TV fee and, for larger or commercial users, income-tax withholding. That is why every rate here is editable: plug in the figures your own bill uses and the estimate becomes yours.
Cutting the bill works at the slab level. Because higher slabs cost more per unit, trimming 50 units near the top saves more than trimming 50 at the bottom. LED bulbs, inverter ACs at 26°C and off-peak pumping all cut expensive top-slab units — and the salary tax calculator shows the take-home pay you are planning around.
Frequently Asked Questions
Quick answers about the Electricity Bill Estimator — for anything else, message us on WhatsApp.
What is FPA on my electricity bill?
FPA stands for fuel price adjustment. Tariffs are set for a period, but furnace-oil generation costs move daily, so DISCOs recover the difference as a monthly per-unit surcharge. If your bill shows FPA = 1.20, you pay Rs. 1.20 per unit that month — enter it above and the tool spreads it across your units.
Why is GST applied only above 200 units?
The tool follows the simplified rule that small domestic consumers — 200 units or fewer a month — receive lighter sales-tax treatment, while higher consumption attracts the standard 18% GST. Real bills differ by category and month, so the rate is editable — match it to your own bill.
What is the difference between protected and unprotected consumers?
Protected status goes to domestic consumers who stayed within roughly 200 units for six consecutive months (lifeline consumers use even less), and protected consumers are billed at lower slab rates. The calculator ships with indicative unprotected rates — protected users should enter the lower protected figures printed on their own bill.
How do I read the slab rates from my bill?
Look for the tariff or consumption summary section of your bill: it lists unit ranges (1–100, 101–200, 201–300 and so on) with a rupees-per-unit rate for each. Copy those numbers into the six fields above and the energy cost will match how your DISCO computes the bill.
Is this the official bill calculator of any DISCO?
No. This is an independent estimator with indicative 2025-26-style domestic rates — not affiliated with WAPDA, NEPRA or any DISCO — and it cannot reproduce the exact printed bill with its reading dates and category taxes. Use it for planning; pay and dispute bills only through official channels.
How can I reduce my electricity bill in Pakistan?
Target the expensive top slabs: every unit saved at 62.50 or 66 rupees is worth nearly double one saved at 35. LED bulbs, inverter appliances and a 26°C AC all cut top-slab units — and holding consumption just under 200 units drops the whole bill into cheaper brackets.
