Electricity Bill Calculator Pakistan 2026 Estimate Your Exact Bill with NEPRA Tariff & FPA
Pakistan's electricity bills don't just multiply your units by a fixed rate. They stack multiple variable charges — NEPRA slab rates, FPA, FC Surcharge, NJ Surcharge, Electricity Duty, GST — and the result can surprise even careful consumers. This guide explains every component, walks through a real worked example, and shows you how to use echeckbills.pk's free calculator to get your estimate right before the bill arrives.
The free electricity bill calculator at echeckbills.pk implements exact NEPRA 2026 tariff logic — including the S.R.O. 279(I)/2026 tariff structure. It handles Protected and Unprotected consumer categories, single phase and three phase meters, FPA, FC Surcharge, quarterly adjustments and arrears. The result is a full breakdown of every line item on your electricity bill before FESCO, LESCO, MEPCO or any other DISCO generates it.
But to use it well, you need to understand what each input means. That's what this guide covers.
Why estimating before the bill arrives matters
Electricity bills in Pakistan arrive once a month. By the time you see the total, you've already consumed every unit on it. The bill doesn't tell you what drove the spike — it just shows the result.
Here's the problem. Most Pakistani households check their meter once — when the bill arrives. At that point, there's nothing to be done. If you crossed a slab boundary in week 3 of the billing cycle, you paid the higher rate on every unit from week 1. If the FPA jumped 40% that month, every unit costs more. The bill is what it is.
Checking your meter on the 15th and running it through the calculator changes that. You see your trajectory mid-cycle. 180 units on August 15 with a billing date of August 31 tells you exactly how much more AC usage you can afford before crossing 200 units — and what that crossing would cost at current NEPRA rates and the month's FPA. That's information you can actually act on.
The calculator doesn't just tell you what you owe. It tells you what a decision costs before you make it.
The other use case: estimating bills for properties you manage but don't live in. Landlords in Lahore, Karachi and Faisalabad regularly use calculators to estimate whether a tenant's reported consumption makes sense — before paying their share of a bill they can't directly verify.
How to use the electricity bill calculator
The calculator at Electricity Bill Calculator has 3 input sections. Here's exactly what goes in each field.
Section 01
Consumption details — readings or units
Required
Enter your previous meter reading and current meter reading. The calculator subtracts one from the other to compute units consumed. Or enter units directly in the "Direct Units" field if you already know the number.
FPA Units (Previous Month)This field is for entering last month's FPA unit figure if you want to include it in the adjustment calculation. In most standard residential calculations, you can leave this as zero. Your DISCO includes previous month FPA adjustments automatically on the printed bill.
Sanctioned Load (kW)Your sanctioned load is the maximum load your connection is authorised for — shown on your electricity bill as "Sanctioned Load." Residential single-phase connections are typically 5kW. Three-phase connections are usually 10kW or higher. The calculator uses this for fixed charge determination on some tariff categories.
Use your printed FESCO, LESCO, MEPCO or other DISCO bill to get exact previous and current readings. Don't estimate — one kWh difference doesn't sound like much but it can mean the difference between staying below 200 units and crossing the slab boundary.
Section 02
Consumer category — Protected, Unprotected or Industrial
This field changes everything
This single selection changes the tariff structure the calculator applies. Get it wrong and the estimate is wrong.
Protected (≤200 units)Only applies if your consumption has been 200 units or fewer in each of the past 6 consecutive billing months. Protected consumers get lower subsidised tariff rates. If you consumed 201 units even once in the last 6 months, you don't qualify — select Unprotected.
UnprotectedAnyone who has exceeded 200 units in any of the past 6 months. The vast majority of urban Pakistani consumers fall in this category, especially those running an AC.
IndustrialCommercial and industrial connections with separate tariff structures under NEPRA's industrial schedules. Select this if your bill shows a non-domestic tariff code.
Not sure which category you are? Check the "Tariff" field on any recent printed electricity bill from your DISCO. It will say something like "B1 Domestic" (Unprotected), "B1(a) Protected" or similar. That tells you exactly which category to select.
Section 03
Variable charges — FPA, FC Surcharge, QTR Adj, Arrears, LP Surcharge
FPA is the critical oneVaries every month
These charges are what make Pakistan's electricity bills genuinely hard to predict. The base tariff is fixed. These fields aren't.
FPA (Rs/unit) — Fuel Price AdjustmentEnter the current month's FPA per unit. This is the single most important variable input. NEPRA publishes it monthly. Get the current figure from our FPA Tracker or from nepra.org.pk. A July 2026 FPA of Rs. 2.34/unit on 268 units adds Rs. 627 to your bill.
FC Surcharge — Financing Cost SurchargeA per-unit charge covering power sector financing costs. NEPRA sets it periodically. Your most recent electricity bill will show the current FC Surcharge per unit — copy that figure here.
QTR Adj (DMC) — Quarterly AdjustmentA periodic distribution margin cost adjustment applied quarterly by NEPRA. Not every bill includes this — only quarterly adjustment months. Leave at zero if not applicable.
Arrears (Rs)Any unpaid balance from previous months. If your last bill showed arrears, enter that rupee amount here. The calculator adds it to your total.
LP Surcharge (%) — Late Payment SurchargeEnter 10 if you're estimating what your bill will cost after the due date. The 10% late payment surcharge is applied by every DISCO in Pakistan on overdue bills.
The most common mistake: leaving FPA at zero. That gives you the base energy charges only — your real bill will be significantly higher once FPA is applied. Always enter the current month's FPA before calculating.
NEPRA tariff slabs 2026 — how they actually work
Pakistan's residential electricity tariff is a stepped slab system. The slab structure has one crucial feature most people don't understand: when you cross a slab boundary, the higher rate applies to ALL your units for that month — not just the extra ones above the cutoff.
Units per month | Rate per unit (approx. 2026) | Fixed charge | All-units re-pricing? |
|---|---|---|---|
1 – 50 (Lifeline) | Rs. 3.95 | Rs. 0 | Protected / Lifeline only |
1 – 100 units | Rs. 7.74 | Rs. 75 | No — applies to first 100 only |
101 – 200 units | Rs. 10.06 | Rs. 100 | Yes — all units re-priced |
201 – 300 units | Rs. 14.01 | Rs. 150 | Yes — all units re-priced |
301 – 700 units | Rs. 20.17 | Rs. 200 | ⚠ Yes — large jump at this boundary |
Above 700 units | Rs. 25.09 | Rs. 500 | ⚠ Yes — highest residential slab |
Approximate 2026 NEPRA rates under S.R.O. 279(I)/2026. For official published tariff notifications visit nepra.org.pk. These base rates do not include FPA, surcharges or GST.
The all-units re-pricing is the calculation most people get wrong when estimating manually. If you consume 201 units, you pay Rs. 14.01 on all 201 — not Rs. 7.74 for the first 100, Rs. 10.06 for the next 100 and Rs. 14.01 for just 1 unit. The slab you land in prices your entire consumption. That's why going from 198 to 215 units in a hot month costs Rs. 900-1,400 more, not just Rs. 14.01 × 17 = Rs. 238.
The calculator handles this automatically. You don't need to do the slab math manually — enter your units and it applies the correct slab to your entire consumption.
FPA explained — the charge nobody warns you about
FPA stands for Fuel Price Adjustment. NEPRA calculates it monthly based on the actual cost of fuel Pakistan used to generate electricity — gas, furnace oil, LNG imports, hydro and coal — versus what was projected in the base tariff.
If fuel costs came in higher than projected, every consumer in Pakistan pays more that month. If hydro generation was high and fuel costs were low, the FPA can go negative — a credit on your bill. NEPRA publishes it between the 15th and 20th of each month for the following billing period.
Where to find the current FPA
Check our FPA Tracker for the latest NEPRA FPA figures. We maintain a 12-month history of FPA values across all DISCOs so you can see how much has changed month to month. You can also find official FPA notifications at nepra.org.pk.
The FPA is what makes Pakistan's electricity bills genuinely unpredictable. In July 2026 the FPA was approximately Rs. 2.34 per unit. On a 268-unit consumption that adds Rs. 627. On a 400-unit consumption it adds Rs. 936. And that's before GST at 17% is applied on top of the FPA amount. In summer months when LNG imports are heavy and the grid runs on expensive fuel, the FPA alone can exceed the base energy charge on a high-consumption bill.

Every charge on a Pakistan electricity bill explained
Your electricity bill has more line items than most people realise. Here's the complete list — what each is, who sets it and whether it changes monthly.
Charge | Full name | Set by | Changes monthly? |
|---|---|---|---|
Energy charges | Base energy consumption × slab rate | NEPRA | No (tariff is periodic) |
FPA / FAC / FCA | Fuel Price Adjustment / Fuel Adjustment Charge | NEPRA | Yes — every month |
FC Surcharge | Financing Cost Surcharge | NEPRA | Periodic |
NJ Surcharge | Neelum Jhelum Surcharge | NEPRA | No (fixed per unit) |
QTR Adj (DMC) | Quarterly Distribution Margin Cost Adjustment | NEPRA | Quarterly only |
Electricity Duty (ED) | Punjab Provincial Electricity Tax | Punjab Government | No |
GST | General Sales Tax at 17% | FBR | No |
TV Licence Fee | Pakistan Television Licence Fee | PTV / Govt | No — Rs. 35/month fixed |
Fixed Charges | Per-connection monthly fixed amount | NEPRA (per slab) | No |
LP Surcharge | Late Payment Surcharge | DISCO | N/A — applies only after due date |
Arrears | Unpaid balance from previous months | DISCO | Yes — carried forward each cycle |
The calculator at echeckbills.pk includes fields for FPA, FC Surcharge, QTR Adj, Arrears and LP Surcharge — giving you a complete picture rather than just the base energy cost. This is what separates it from simple slab calculators that only show energy charges without all the variable additions.
Worked example — a Faisalabad household in August 2026
Let's run a real calculation. Consumer: Khalid Mehmood in Peoples Colony, Faisalabad. FESCO. Unprotected. Single phase. August 2026. Units consumed: 268. FPA: Rs. 2.34/unit. FC Surcharge: Rs. 0.43/unit. NJ Surcharge: Rs. 0.24/unit.

Worked example: FESCO Faisalabad — 268 units, August 2026, Unprotected consumer. Energy charges + FPA + surcharges + GST = Rs. 5,680. Run your own calculation at echeckbills.pk/tools/electricity-bill-calculator.
Here's the full breakdown for the worked example:
⚡ FESCO Faisalabad — August 2026 · 268 Units · Unprotected
Energy charges (268 × Rs. 14.01 — 201-300 slab)Rs. 3,755
FPA — Fuel Price Adjustment (268 × Rs. 2.34)+ Rs. 627
FC Surcharge (268 × Rs. 0.43)+ Rs. 115
NJ Surcharge (268 × Rs. 0.24)+ Rs. 64
Electricity Duty (1.5%)+ Rs. 71
GST 17% on applicable charges+ Rs. 838
Fixed charges (201-300 slab)+ Rs. 150
TV Licence Fee (PTV)+ Rs. 35
ArrearsRs. 0
TOTAL PAYABLERs. 5,680
Notice the gap between "energy charges alone" (Rs. 3,755) and the actual total (Rs. 5,680). That's Rs. 1,925 in surcharges, FPA, duty and GST — 51% on top of the base energy cost. This is why estimates that only use the slab rate times units give you a number that's nearly half the real bill.
The calculator at echeckbills.pk includes every one of these components. Enter the FPA for the month, the FC Surcharge per unit, any arrears, and whether you expect a late payment — and the total is accurate.
Protected vs Unprotected consumers — what's the difference?
NEPRA introduced the Protected/Unprotected consumer categorisation to give low-income households access to lower electricity tariff rates.
Protected consumers
A consumer is Protected if their electricity consumption has been 200 units or fewer in each of the past 6 consecutive billing months. Protected consumers get lower per-unit rates — around Rs. 3.95-7.74 per unit depending on the consumption level — compared to Unprotected rates.
⚠ Crossing 200 units once removes Protected status
If a Protected consumer's consumption exceeds 200 units in any single billing month, they lose Protected status for at least the next 6 months. They move to Unprotected tariff rates and must maintain 200-or-fewer units for 6 consecutive months to regain Protected status. This is the tariff trap that hits low-income households in summer — one hot month of higher AC usage can push up their bill rate for half a year.
Unprotected consumers
Anyone who has consumed more than 200 units in any of the past 6 billing months. Most urban Pakistani households with an air conditioner are Unprotected. The calculator defaults to Unprotected for standard residential calculation.
Your DISCO bill shows your current category in the "Tariff" field on the printed bill. B1 Domestic typically means Unprotected. B1(a) or similar notation indicates Protected status. If you're unsure, check your actual downloaded bill at echeckbills.pk — the tariff code is printed clearly.
Single phase vs three phase meters
The calculator includes a phase type selector — Single Phase or Three Phase. Here's what each means and which one to select.
Single phase
Standard residential electricity connection. 220V, single hot wire. The vast majority of Pakistani homes — apartments, small houses, urban middle-class properties — have single-phase connections. Sanctioned load is typically 5kW. If you have a basic home setup with fans, lights, one or two ACs and a water pump, you almost certainly have a single-phase connection.
Three phase
Higher-capacity connection with three hot wires. 380V. Used for larger homes with heavy loads — multiple ACs, heavy motor pumps, workshop equipment — and all commercial and industrial premises. Sanctioned load is typically 10kW and above. Three-phase connections have different fixed charges under NEPRA tariff.
Not sure which you have? Check your electricity meter — a three-phase meter is visibly larger with 3 separate current wires entering it. Or check your printed electricity bill, which shows the connection type. You can also ask your DISCO's helpline.
Does the calculator work for all 11 DISCOs?
Yes. The calculator at Electricity Bill Calculator works for all 11 DISCOs in Pakistan — MEPCO, LESCO, FESCO, GEPCO, IESCO, PESCO, HESCO, SEPCO, QESCO, TESCO and HAZECO.
All DISCOs use the same NEPRA national residential tariff structure. The base slab rates, Electricity Duty, GST and fixed charges are the same across all DISCOs. The only value that may differ slightly between DISCOs in a given month is the FPA — NEPRA can apply slightly different FPA rates to different DISCOs depending on their actual fuel mix. Check our FPA Tracker for the current FPA by DISCO before calculating.
DISCO | Coverage | Same NEPRA tariff? | Check actual bill |
|---|---|---|---|
MEPCO | South Punjab — Multan, Bahawalpur, DG Khan | Yes | |
LESCO | Lahore, Sheikhupura, Kasur, Nankana Sahib | Yes | |
FESCO | Faisalabad, Jhang, Toba Tek Singh, Chiniot | Yes | |
GEPCO | Gujranwala, Sialkot, Gujrat, Narowal | Yes | |
IESCO | Islamabad, Rawalpindi, Attock, Chakwal | Yes | |
PESCO | KP settled districts — Peshawar, Mardan, Swat | Yes | |
QESCO | All Balochistan — Quetta, Gwadar, Turbat | Yes | |
HAZECO | Hazara — Abbottabad, Mansehra, Haripur | Yes |
After estimating, you can check your actual live bill at echeckbills.pk using your 14-digit reference number. The actual bill from PITC shows your exact charges rather than an estimate — useful for comparing against the calculator output and spotting any discrepancies.
6 ways to lower what the calculator shows
Check mid-month and use the calculator to project your trajectory — read your meter on the 15th and enter half-month readings into the calculator. Double the units to get a projected monthly total. If the projection puts you across a slab boundary, you still have 2 weeks to reduce consumption before the billing date locks in your rate.
Stay under 200 units if you're near Protected status — a Protected consumer at 198 units pays significantly less than an Unprotected consumer at 201 units. The difference isn't just 3 units — it's the tariff rate on all 201 units at the higher rate. Run both figures through the calculator to see the exact rupee difference for your situation.
Enter the actual FPA — not zero — the most common calculator mistake. Zero FPA gives you an optimistic estimate that's always below the real bill. Enter the current month's FPA from our FPA Tracker every time you calculate. In summer months the FPA alone can add 15-25% to your total.
Set AC temperature to 26°C — each degree below 26°C adds approximately 8% to AC power draw. A household at 268 units in August spending 2 extra AC hours per day at 22°C instead of 26°C adds around 18 units. Run those 286 units through the calculator versus 268 — the Rs. difference is visible immediately and it's real money.
Switch to an inverter AC if you're in the 301-700 unit slab — inverter ACs use 40-60% less power than conventional units. If the calculator shows you're in the Rs. 20.17/unit slab, an inverter AC is likely the fastest payback appliance upgrade available. Run the savings through the calculator with the lower estimated units.
Pay on time and enter LP Surcharge = 0 — the LP Surcharge field in the calculator accepts a percentage. If you enter 10 (the standard late payment surcharge), you see exactly what delay costs in rupees. On a Rs. 5,680 bill that's Rs. 568 extra for a few days' delay. JazzCash is free and takes 3 minutes — check your actual bill at echeckbills.pk, pay immediately, and enter LP Surcharge = 0 in every future calculation.
Frequently asked questions
Electricity bill calculator questions
How do I calculate my electricity bill in Pakistan 2026?
Use the free calculator at echeckbills.pk/tools/electricity-bill-calculator. Enter your previous and current meter readings (or units directly), select Protected or Unprotected, enter the current FPA per unit, and click Calculate. The calculator applies exact NEPRA 2026 slab rates, FPA, FC Surcharge, NJ Surcharge, Electricity Duty and 17% GST to give your complete estimated bill breakdown.
What is the difference between Protected and Unprotected electricity consumers?
Protected consumers have consumed 200 units or fewer in each of the past 6 consecutive billing months. They get lower subsidised tariff rates. Unprotected consumers have exceeded 200 units in any month in the past 6 months — most urban Pakistani households with an AC fall in this category. Your bill's "Tariff" field shows your current category.
What is FPA in electricity bill and how does it affect my total?
FPA (Fuel Price Adjustment) is a monthly variable charge set by NEPRA based on actual grid fuel costs. It's multiplied by your units consumed and added to your bill. In July 2026 the FPA was Rs. 2.34/unit — on 268 units that's Rs. 627 extra. In summer months it can add Rs. 800-2,500 to a single bill. Always enter the current month's FPA in the calculator — find it at our FPA Tracker.
What is FC Surcharge on electricity bill Pakistan?
FC Surcharge (Financing Cost Surcharge) is a per-unit charge covering power sector debt financing costs, set by NEPRA. It appears on every electricity bill as a separate line item. Enter the per-unit value from your most recent printed bill into the calculator's FC Surcharge field for an accurate estimate.
What is NJ Surcharge on electricity bill Pakistan?
NJ Surcharge (Neelum Jhelum Surcharge) is a per-unit levy collected to repay construction financing for the Neelum Jhelum Hydropower Project. It appears on every electricity bill in Pakistan at approximately Rs. 0.10-0.35 per unit depending on the NEPRA notification in effect. The calculator includes it automatically.
What are NEPRA electricity tariff slabs for 2026?
NEPRA 2026 residential slabs (approximate, under S.R.O. 279(I)/2026): 1-50 units (Lifeline) at Rs. 3.95/unit; 1-100 units at Rs. 7.74/unit; 101-200 units at Rs. 10.06/unit (all units re-priced); 201-300 units at Rs. 14.01/unit; 301-700 units at Rs. 20.17/unit; above 700 units at Rs. 25.09/unit. When you cross a slab boundary, the higher rate applies to ALL your units — not just the extras. For the official tariff, visit nepra.org.pk.
Can I use the electricity bill calculator for any DISCO in Pakistan?
Yes. The calculator works for all 11 DISCOs — MEPCO, LESCO, FESCO, GEPCO, IESCO, PESCO, HESCO, SEPCO, QESCO, TESCO and HAZECO. All use the same NEPRA national tariff. The only value that differs slightly between DISCOs is the FPA — check our FPA Tracker for the current FPA per DISCO.
Why is my actual bill different from the calculator estimate?
The calculator gives an estimate based on what you enter. Small differences from the actual bill can occur if: the FPA you entered differs from what NEPRA actually applied for your billing period; your DISCO applied a quarterly DMC adjustment not captured; or there are arrears not entered. For your exact bill, check it live at echeckbills.pk using your 14-digit reference number.
