Electricity Bill
Electricity Bill Calculator
Estimate your electricity bill before it arrives. Enter the units from your meter, or subtract your previous reading from your current one, and this calculator applies the same NEPRA slab rates used by every DISCO, so you get a realistic rupee estimate, not a guess.
- Works for every WAPDA DISCO: LESCO, MEPCO, FESCO, IESCO, GEPCO, PESCO, HESCO, SEPCO, QESCO, TESCO, and HAZECO
- Uses the official NEPRA protected and non-protected slab rates, fixed charge, and 18% GST
- Shows the full breakdown, and warns you if you're close to the 200-unit protected cliff
Electricity Bill Calculator
Every DISCO, one formula
Pakistan's domestic electricity tariff, set by NEPRA, the National Electric Power Regulatory Authority, is not one flat rate. It runs on two separate rate tables: a low, subsidised "protected" table for households using 200 units a month or less, and a much steeper "non-protected" table for everyone above that. Every WAPDA-origin distribution company charges the same uniform tariff, so the same formula applies whether your bill comes from LESCO, MEPCO, FESCO, or any other DISCO. K-Electric, which serves Karachi, is not on this uniform tariff and publishes its own separate rates. This calculator runs the NEPRA formula for you and explains the one detail that catches most people out: what happens when you cross 200 units.

How the Electricity Bill Calculator Works
Get an estimate in three steps, using either your units or a raw meter reading.
- 1
Enter your units or meter reading
Type the units consumed this month directly, or switch to meter reading mode and enter your previous and current readings; the calculator subtracts them for you automatically.
- 2
The calculator checks your category
Units at or below 200 are billed as protected; above 200, the entire month is billed as non-protected. This is decided automatically from what you enter, since it depends on your total for the month.
- 3
Read the breakdown
See the energy charge by slab, the fixed charge, TV fee, and GST added separately, then the estimated total at the bottom.

The 200-Unit Cliff: Why a Few Extra Units Cost So Much
Unlike gas, Pakistan's domestic electricity tariff is not fully progressive. Protected and non-protected consumers are billed from two completely different rate tables, and which one applies depends on your whole month's total, not just the units above 200.
A household using 190 units a month is billed entirely on the protected table, at Rs 10.54 to Rs 13.01 a unit. The same household using 210 units, just 20 units more, is billed entirely on the non-protected table instead, starting at Rs 22.44 a unit for even the first 100 units. The result is a bill that can roughly double for a small increase in usage, not because of the extra 20 units themselves, but because the whole month drops out of the protected category. If your usage is close to 200 units, this calculator will flag it so you can see how close you are to the cliff.
Worked example
190 units (protected) comes to an estimated Rs 3,021. 210 units (non-protected) comes to an estimated Rs 6,963, more than double, for 20 extra units. Both figures exclude the Fuel Charges Adjustment, which is added on top of either amount.

NEPRA Domestic Electricity Tariff Slabs
The rates this calculator uses, current for every WAPDA DISCO. Your category for the month depends on your total units, not a fixed status.
| Slab (up to) | Rate (Rs/unit) |
|---|---|
| 100 units | 10.54 |
| 200 units | 13.01 |
| Slab (up to) | Rate (Rs/unit) |
|---|---|
| 100 units | 22.44 |
| 200 units | 28.91 |
| 300 units | 33.10 |
| 400 units | 37.99 |
| 500 units | 40.22 |
| 600 units | 41.62 |
| 700 units and above | 42.76 |
Fixed charge: Rs 200/month (protected, up to 100 units), Rs 300/month (protected, 101-200 units), or Rs 400/month (non-protected). A Rs 35 TV licence fee and 18% GST apply on top. Rates reflect NEPRA's uniform FY2025-26 domestic tariff for WAPDA DISCOs; K-Electric is excluded, see below.
This Calculator Does Not Cover K-Electric
K-Electric, the private utility serving Karachi and its surrounding areas, is not billed on NEPRA's uniform DISCO tariff used above. NEPRA sets K-Electric's rates separately, on its own schedule and its own slab structure, so plugging K-Electric units into this calculator would give you the wrong number. If you are a K-Electric customer, check your bill directly, or look up K-Electric's own published tariff for an accurate estimate.
Why This Is an Estimate
This calculator uses NEPRA's official protected and non-protected slab rates, the fixed charge, the TV licence fee, and 18% GST, so it lands close to a real bill. It leaves out the Fuel Charges Adjustment (FCA) and Quarterly Tariff Adjustment (QTA), two surcharges NEPRA revises every month and every quarter based on fuel costs and DISCO performance; these can add a noticeable amount and are impossible to bake into a calculator without it going stale within weeks. Provincial electricity duty, which varies slightly by province, is also excluded. Your official bill includes all of these. Use this tool to estimate the core of your bill and to understand the protected cliff, then check your official bill for the exact payable amount.

Electricity Bill Calculator FAQs
How do I calculate my electricity bill?
Find your units from your meter or your last bill and enter them above. The calculator checks whether your total is 200 units or less (protected) or above 200 (non-protected), applies the matching NEPRA slab rates, adds the fixed charge, TV fee, and 18% GST, and shows an estimated total.
How is K-Electric's bill calculated?
Differently. K-Electric is not on NEPRA's uniform DISCO tariff this calculator uses; NEPRA approves K-Electric's rates on a separate schedule. This tool covers LESCO, MEPCO, FESCO, IESCO, GEPCO, PESCO, HESCO, SEPCO, QESCO, TESCO, and HAZECO only. K-Electric customers should check their bill directly.
What is the electricity bill calculation formula in Pakistan?
Energy charge (units billed progressively within your protected or non-protected slab table) plus a fixed monthly charge plus a Rs 35 TV licence fee, with 18% GST applied to that combined total. Fuel Charges Adjustment and provincial electricity duty are added separately by your DISCO and are not part of this formula.
How do I calculate my electricity bill by units?
Enter the units shown on your meter or your last bill into the calculator above. If you only have your previous and current meter readings, switch to meter reading mode and it will subtract them for you to get the units used.
What is a protected electricity consumer?
A domestic consumer using 200 units or less in a month, billed on NEPRA's lower, subsidised rate table. Crossing 200 units in any month moves your entire bill for that month to the higher non-protected table, not just the extra units.
Why did my electricity bill jump so much this month?
The most common reason is crossing from 200 units into non-protected territory, which switches your whole month's energy charge to a much higher rate table, not just the units above 200. A Fuel Charges Adjustment increase can also raise the bill even at the same usage level.
Does this calculator work for a sub-meter?
Yes, if your sub-meter reads in the same units (kWh) as a normal domestic meter. Enter the units your sub-meter recorded this month, or use meter reading mode with its previous and current readings, the same as a main meter.
Does this cover commercial electricity bills?
No. This calculator uses NEPRA's domestic (residential) tariff only. Commercial and industrial connections are billed on different NEPRA tariff categories with different rates and structures.
Is this calculator accurate?
It uses NEPRA's real domestic slab rates and the protected/non-protected logic, so it lands close to your actual bill. It excludes the Fuel Charges Adjustment and electricity duty, which change monthly and by province, so treat the result as a close estimate and check your official bill for the exact amount.
Is this the official NEPRA or DISCO calculator?
No. This is an independent estimate built on NEPRA's published domestic tariff. For your exact bill, check it online through your DISCO directly using your reference number.
