Enter the units on your bill, your sanctioned load and whether you are protected. With the adjustments now in the calculator, 300 units on an unprotected 2 kW connection comes to about Rs 14,448, and 200 protected units to about Rs 4,021.
Every company from LESCO to K-Electric charges the same national tariff, so one calculator works for all of them. What changes from bill to bill is your consumer type, your load, and whether your bill carries electricity duty.
How a Pakistani electricity bill is built
A home bill is a stack of separate charges. The calculator adds them in this order.
- Cost of electricity. Units times the slab rate. This is the biggest line.
- Fixed charges. A monthly charge per kW of sanctioned load, not per connection. At 2 kW and 250 units, that is 2 × Rs 350 = Rs 700. Lifeline users pay none.
- Fuel adjustment (FCA or FPA). NEPRA sets it each month and it is billed two months later. The calculator uses Rs 1.1086 per unit, the August 2026 fuel adjustment, billed in October 2026. It is charged on the units you used in the fuel adjustment month, not this month's units. The bill names the month, e.g. "FPA for JUL-26", and its 12-month history shows your units for that month.
- Quarterly adjustment (QTA). Rs 0.5194 per unit on September, October and November 2026 bills. On the first bill after a change, the old and new rates are split by the days of your reading period, so that bill can show a blended figure.
- FC surcharge. The financing cost surcharge, shown as "FC-SUR" or "F.C. surcharge". Unprotected homes pay Rs 3.23 per unit and protected homes Rs 0.43. Lifeline homes do not pay it. It repays loans taken to clear circular debt.
- Electricity duty. A provincial duty of 1.5%, charged on cost of electricity plus QTA, and separately on the fuel adjustment.
- GST at 18%. Charged on cost of electricity, surcharge, QTA, fixed charges, electricity duty and meter rent. The fuel adjustment gets its own GST line, charged on the adjustment plus its duty. Both GST lines are printed in whole rupees.
- Income tax. 7.5% of the whole bill, only for people not on FBR's Active Taxpayers List, and only when the bill is Rs 25,000 or more.
- Meter rent. Small and not the same everywhere, so it is an optional box.
The bill adds up the first four lines, meter rent and the fuel adjustment as electricity charges, and the duty, GST and income tax as government charges. The calculator shows both subtotals so you can match them line by line.
There is no PTV fee any more. It was removed from bills in July 2025.
Protected, unprotected and lifeline
Your consumer type matters more than anything else on the bill.
- Lifeline: a single-phase connection of up to 1 kW using 100 units or less. No fixed charge, no fuel or quarterly adjustment.
- Protected: 200 units or less in each of the last six months. Rates are Rs 10.54 and Rs 13.01.
- Unprotected: everyone else. Rates run from Rs 22.44 up to Rs 47.20.
Protected users get the benefit of one previous slab. So 150 units is billed as 100 × 10.54 plus 50 × 13.01.
Unprotected users get no slab benefit. All units are charged at the rate of the slab the total falls in. That is why 201 units costs far more than 200. On 2 kW, 200 units is Rs 8,786 and 201 units is Rs 9,952.
Cross 200 units once as a protected user and you lose protected status for the following six months. In September 2026 the Power Division said it was reviewing this rule; until a change is notified, it still applies.
Domestic tariff in force (February 2026)
Base rates for homes with a sanctioned load under 5 kW, from the NEPRA uniform tariff. These have not changed since February 2026, because tariff rebasing now happens on 1 January.
| Type | Units per month | Rs per unit | Fixed Rs per kW |
|---|---|---|---|
| Lifeline | Up to 50 | 3.95 | None |
| Lifeline | 51 to 100 | 7.74 | None |
| Protected | 1 to 100 | 10.54 | 200 |
| Protected | 101 to 200 | 13.01 | 300 |
| Unprotected | 1 to 100 | 22.44 | 275 |
| Unprotected | 101 to 200 | 28.91 | 300 |
| Unprotected | 201 to 300 | 33.10 | 350 |
| Unprotected | 301 to 400 | 36.46 | 400 |
| Unprotected | 401 to 500 | 38.95 | 500 |
| Unprotected | 501 to 600 | 40.22 | 675 |
| Unprotected | 601 to 700 | 41.85 | 675 |
| Unprotected | Above 700 | 47.20 | 675 |
These are base rates only. Adjustments and taxes add a large amount per unit on top. See what one unit really costs.
Worked example: a real bill of 228 units
Here is a real LESCO bill for April 2026, used to test the calculator. It was an unprotected 2 kW connection using 228 units, and the total was Rs 11,028. Here is how that bill adds up, using the rates billed that month (FPA Rs 0.6993 and QTA Rs 0.3504).
| Line | Working | Rs |
|---|---|---|
| Cost of electricity | 228 × 33.10 | 7,546.80 |
| Fixed charges | 2 kW × 350 | 700.00 |
| FC surcharge | 228 × 3.23 | 736.44 |
| Quarterly adjustment | 228 × 0.3504 | 79.89 |
| Fuel adjustment | 228 × 0.6993 | 159.44 |
| Meter rent | as billed | 7.50 |
| Electricity charges | 9,230.07 | |
| Electricity duty | 1.5% of (7,546.80 + 79.89) | 114.40 |
| GST | 18% of 9,185.03, rounded | 1,653.00 |
| Duty on fuel adjustment | 1.5% of 159.44 | 2.39 |
| GST on fuel adjustment | 18% of (159.44 + 2.39), rounded | 29.00 |
| Government charges | 1,798.79 | |
| Total | 11,028.86 |
The printed bill showed Rs 7,546.95 for electricity, because the cost is adjusted for the days in the reading period, and the total was Rs 11,028. The calculator gives Rs 11,029. To check yours, open Adjustments and taxes and type in the FCA and QTA from your own bill.
With the adjustments now in the calculator, the same 228 units come to about Rs 11,178 before meter rent.
Bill at common unit levels
Unprotected, 2 kW sanctioned load, the current adjustments (August 2026 fuel adjustment, billed in October 2026), electricity duty on, non-filer.
| Units | Cost of electricity | Estimated total bill |
|---|---|---|
| 100 | Rs 2,244 | Rs 3,913 |
| 200 200 units bill | Rs 5,782 | Rs 8,786 |
| 300 300 units bill | Rs 9,930 | Rs 14,448 |
| 400 400 units bill | Rs 14,584 | Rs 20,716 |
| 500 500 units bill | Rs 19,475 | Rs 29,439 |
| 600 | Rs 24,132 | Rs 36,500 |
| 700 | Rs 29,295 | Rs 43,767 |
When a non-filer's bill reaches Rs 25,000, 7.5% income tax is added; getting on the Active Taxpayers List removes it. For 100 and 200 units, protected users pay far less; see the 200 units page.
Bills at 100, 600 and 700 units
100 units: lifeline, protected or unprotected
| Type | Rate | Estimated bill |
|---|---|---|
| Lifeline | Rs 7.74 | Rs 927 |
| Protected | Rs 10.54 | Rs 1,980 |
| Unprotected | Rs 22.44 | Rs 3,913 |
Lifeline is for single-phase connections up to 1 kW that use 100 units or less. Lifeline homes pay no fixed charge, no fuel or quarterly adjustment and no FC surcharge, and lifeline rates have no slab benefit: at 100 units all 100 are billed at the higher lifeline rate. Going over 100 units ends lifeline billing for that month. For a protected home, unit 101 moves into the next slab and the fixed charge per kW also rises, so 101 units cost Rs 2,233 against Rs 1,980 for 100.
600 units: load and filer status
| Situation | Estimated bill |
|---|---|
| 2 kW, duty, non-filer | Rs 36,500 |
| 2 kW, duty, filer | Rs 33,953 |
| 2 kW, no duty, non-filer | Rs 36,022 |
| 3 kW, duty, non-filer | Rs 37,356 |
From 501 units the fixed charge is at its highest, Rs 675 per kW, so each extra kW of sanctioned load adds that much plus GST and, for non-filers, income tax.
700 units and the top slab
| Non-filer | Filer | |
|---|---|---|
| 700 units | Rs 43,767 | Rs 40,713 |
| 701 units | Rs 48,655 | Rs 45,260 |
At 701 units the rate on every unit goes from Rs 41.85 to Rs 47.20, the biggest per unit step in the domestic tariff. A home that regularly runs above 700 in summer may want to look at where the load goes, such as running an AC at a higher setting or for fewer hours.
If your bill shows peak and off-peak readings, your connection is on time of use rates; use the peak hours bill calculator instead. Getting a new meter? The new connection fee calculator adds up the company's charges.
This is an estimate. It is not an official bill and qaaf is not linked to NEPRA or any distribution company. Arrears, late payment surcharge, deferred amounts and meter-reading dates all change the final figure. Always pay the amount on your own bill.
Questions people ask
How is the electricity bill calculated in Pakistan?
Units are multiplied by the slab rate, then fixed charges per kW of sanctioned load are added. On top go the fuel adjustment, the quarterly adjustment and the FC surcharge (Rs 3.23 a unit, or Rs 0.43 for protected homes). Electricity duty of 1.5% and GST of 18% follow, and non-filers pay 7.5% income tax on bills of Rs 25,000 or more.
Why did my bill jump when I crossed 200 units?
Two things happen at 201 units. You leave the protected category, so the rate moves from Rs 13.01 to the unprotected rates. And unprotected bills charge every unit at the slab rate, so 201 units is billed at Rs 33.10 each. You also stay unprotected for the next six months.
Do I pay electricity duty on my home bill?
It depends on your province and your bill. Punjab passed a law in 2025 exempting homes, yet an April 2026 LESCO bill still showed 1.5% duty. Look for an "electricity duty" or "ED" line on your bill. If it is not there, untick the duty box in the calculator.
What is the F.C. surcharge on my bill?
It is the financing cost surcharge: Rs 3.23 per unit for unprotected homes and Rs 0.43 for protected homes. Lifeline homes do not pay it. It pays back the loans taken to clear part of the power sector circular debt and is expected to stay on bills until 2031. GST is charged on it. It is separate from the NEPRA tariff, so it does not appear in the rate table.
How can I avoid income tax on my electricity bill?
Income tax of 7.5% applies only to consumers who are not on FBR's Active Taxpayers List, and only when the bill reaches Rs 25,000. If the name on the connection is on the ATL, the tax is not charged. Tick the ATL box in the calculator to see the bill without it.
Why is the quarterly adjustment on my bill different from the calculator?
Because your reading period crossed a change of rate. When the reading dates span two quarters, the old and new rates are split by days, so the first bill of a quarter shows a blended figure, which can even be negative. Type the figure from your bill into the quarterly adjustment box, including any minus sign.
When does the fuel adjustment on my bill change?
Every month. NEPRA decides the fuel adjustment for each month after a public hearing, and it is billed two months later. The calculator uses the August 2026 fuel adjustment, billed in October 2026 at Rs 1.1086 a unit. If your bill shows a different FPA, type it into the fuel adjustment box.
How much is a 100 unit electricity bill?
About Rs 1,980 for a protected home with a 2 kW load, Rs 927 on the lifeline tariff and Rs 3,913 for an unprotected home, with the adjustments now in the calculator, duty and GST. Enter your own load above for your figure.
Bijli ka bill kaise calculate karein?
Bill par likhe units, apna sanctioned load aur protected ya unprotected status upar darj karein. Calculator unit rate, fixed charges, fuel adjustment, quarterly adjustment, FC surcharge, duty aur GST alag alag jor kar bill bata deta hai. Maslan 300 units par unprotected 2 kW ghar ka bill takreeban Rs 14,448 banta hai.
