GEPCO Bill Calculator | Estimate Your Electricity Bill:-

Use this free GEPCO bill calculator to estimate your electricity bill before it arrives. Enter your units, pick your billing month, and the tool builds an itemised estimate line by line — energy charges, fixed charges, fuel cost adjustment, quarterly adjustment, duty and taxes — using the NEPRA-approved rates that GEPCO applies across Gujranwala, Gujrat, Sialkot, Hafizabad, Mandi Bahauddin and Narowal.

Most calculators give you one number and no explanation. This one shows its working, because the working is where your money goes. You will see exactly which tariff slab you landed in, what the current FCA added, and how much of your total is tax rather than electricity.

GEPCO Bill Calculator

Estimate your electricity bill with current NEPRA-approved rates, taxes and adjustments.

How This GEPCO Bill Calculator Works:-

The calculator follows the same sequence GEPCO’s billing system uses. First, it works out your consumer class — lifeline, protected, unprotected, or time-of-use. Next, it prices your units against the correct slab or TOU rate. Then it layers on every adjustment and levy in the order they appear on a real bill.

Here is the full charge stack, in sequence:

  1. Energy charge — your units multiplied by the slab or TOU rate for your class.
  2. Fixed charges — a monthly amount based on your sanctioned load in kW, introduced for domestic consumers in the January 2026 tariff restructuring.
  3. C. surcharge — a per-unit financing-cost surcharge, currently Rs 3.23, applied when consumption exceeds 200 units.
  4. Fuel charges adjustment (FCA) — a monthly per-unit correction notified by NEPRA, reflecting actual generation fuel costs from roughly two months earlier.
  5. Quarterly tariff adjustment (QTA) — a per-unit amount spread across three billing months; it can be negative, and the June–August 2026 adjustment is a relief of about Rs 1.99 per unit.
  6. Electricity duty — a provincial levy of 1.5% on variable charges.
  7. GST — 18% applied to the taxable charges above.
  8. PTV fee — a flat Rs 35 on domestic and Rs 60 on commercial connections.
  9. Advance income tax — applies to commercial and industrial bills, adjustable for tax filers.

Because rates change constantly, the calculator separates its formulas from its numbers. The formulas rarely change. The numbers — slab rates, the month’s FCA, the quarter’s QTA, tax percentages — sit in a dated configuration that we update whenever NEPRA or the government notifies a change. The verification date is printed under every estimate, so you always know how fresh the rates are.

GEPCO Tariff Categories: Which Rates Apply to You:-

GEPCO does not invent its own prices. NEPRA determines one uniform tariff for all distribution companies, and GEPCO applies it across its six districts. Your bill depends on which category — and which branch within it — your connection falls under.

Residential (Tariff A-1)

Household connections split into four branches, and the differences between them are dramatic:

  • Lifeline — up to 100 units with a sanctioned load of 1 kW or less. Heavily subsidised rates, and exempt from FCA, fixed charges and the F.C. surcharge.
  • Protected — you qualify only if you have not exceeded 200 units in any of the previous six billing months. Protected rates currently sit in the roughly Rs 10.5–13 per unit range.
  • Unprotected — everyone else. The slab ladder currently runs from about Rs 22.44 up to Rs 47.20 per unit before adjustments and taxes.
  • Time-of-use (TOU) — mandatory for sanctioned loads of 5 kW and above. Peak evening units cost roughly Rs 46.85; off-peak units roughly Rs 34.53.

Since January 2026, domestic consumers above the lifeline band also pay a fixed monthly charge based on sanctioned load. That is why the calculator asks for your load in kW — it is printed on your paper bill next to your tariff code.

Commercial (Tariff A-2)

Shops, offices and other business premises pay a flat commercial rate — currently around Rs 37.44 per unit — when the sanctioned load is 5 kW or below. Above 5 kW, TOU metering applies with separate peak and off-peak pricing. Commercial bills also carry a higher PTV fee and advance income tax, which tax filers can adjust against their annual return.

Industrial (Tariffs B1–B4)

Industrial connections in the Gujranwala and Sialkot belt mostly fall under B1 (below 25 kW) or B2 (25–500 kW). These are two-part tariffs: you pay energy charges on peak and off-peak units, plus demand charges on your maximum demand indicator (MDI) reading, with category minimums of roughly Rs 350 for B1 and Rs 2,000 for B2 even at zero consumption. The January 2026 restructuring cut industrial rates by around Rs 4.58 per unit — meaningful relief for export units. B3 and B4 connections carry negotiated terms, so estimate those directly with GEPCO.

The 200-Unit Line: The Most Expensive Two Units in Pakistan:-

If you remember one thing from this page, make it this. Protected status is not decided by this month’s bill alone — you keep it only while you stay at or below 200 units in every one of the previous six billing months.

Cross the line once, even by two units, and two things happen. Your current month is billed at unprotected rates on the entire consumption, not just the excess. And you lose protected pricing for the following six months, regardless of how little you use in them.

A household at 198 units pays protected rates of roughly Rs 13 per unit on its top slab. The same household at 202 units is billed at unprotected rates across all 202 units — the per-unit cost more than doubles, and the damage repeats for half a year. The calculator warns you as you approach the line, because a Rs 500 saving in June can genuinely prevent Rs 20,000 of extra billing by December.

Worked Example: 300 Units, Unprotected, August 2026

Sample calculation

Here is roughly how a typical unprotected household bill assembles, using a 2 kW sanctioned load:

Line Item Basis Amount (Approx.)
Energy charge 300 units × Rs 33.10 (201–300 band) Rs 9,930
Fixed charges 2 kW × Rs 400 Rs 800
F.C. surcharge 300 units × Rs 3.23 Rs 969
FCA Per the month’s notification Varies
QTA (Jun–Aug credit) 300 units × −Rs 1.99 − Rs 597
Electricity duty 1.5% of variable charges ≈ Rs 155
GST 18% of taxable charges ≈ Rs 2,000
PTV fee Flat Rs 35

The striking part is the last column’s shape: on a typical unprotected bill, adjustments, surcharges, duty and taxes add 30–40% on top of the energy itself. That is why two households using identical units in different months can receive very different bills — and why an estimate that ignores the stack will always mislead you.

Five Practical Ways to Bring the Estimate Down:-

  • Guard the 200-unit line in shoulder months. April, May, October and November are usually winnable; one disciplined month protects six.
  • If you are on TOU, shift laundry, ironing, water pumping and EV charging outside peak evening hours — the peak premium is roughly Rs 12 per unit.
  • Check your slab position before month-end. If you are a handful of units past a boundary, a few days of restraint can re-rate the entire month downward.
  • Match your sanctioned load to reality. Since fixed charges now scale per kW, a load higher than you need is a standing monthly cost.
  • Read your own meter weekly. Estimated readings that overshoot push you into higher slabs; a photo log makes corrections straightforward.

Check the Real Bill Once It Issues:-

This calculator tells you what to expect. Once GEPCO issues the actual bill, check it online in seconds with your 14-digit reference number — the amount, due date and history come straight from the official portal. If you need a copy for payment, the duplicate bill carries the same reference number and is accepted everywhere the original is.

Frequently Asked Questions

It applies the same slab rates, adjustments and taxes printed on real GEPCO bills, and we verify the figures against NEPRA notifications — the verification date appears under every estimate. Treat the result as a close estimate rather than a guarantee: arrears, pro-rata billing for reading periods that are not exactly one month, and subsidy corrections can move the final figure.

There is no single answer — it depends on your category and class. Protected homes currently pay roughly Rs 10.5–13 per unit, unprotected homes roughly Rs 22.44–47.20 by slab, commercial connections about Rs 37.44 flat, and TOU consumers pay by time of day. FCA, QTA, duty and GST then move the effective rate further; the calculator shows your true effective per-unit cost at the bottom of every estimate.

Protected consumers have stayed at or below 200 units in each of the previous six billing months and receive subsidised slab rates. Unprotected consumers have crossed that line at least once in the window and pay substantially higher rates on their entire consumption. Status is re-earned only after six consecutive compliant months.

The fuel charges adjustment is a monthly per-unit correction NEPRA notifies to reconcile assumed fuel costs with actual generation costs, applied with roughly a two-month lag. It can be positive or negative, and it attracts GST. It is usually the reason your bill changed when your units did not.

Since the January 2026 tariff restructuring, domestic and commercial consumers pay a fixed monthly charge per kW of sanctioned load, on top of unit charges. Your load is printed on your bill near the tariff code — most houses are 1 to 5 kW.

Under the current structure, the band your total monthly consumption reaches sets the rate applied to that consumption — which is why crossing a boundary by a few units can raise the entire bill sharply. The calculator flags this and shows what trimming back to the boundary would save.

Yes. Switch to the Commercial tab for A-2 connections, or Industrial for B1 and B2, which include peak/off-peak units and MDI demand charges. B3 and B4 connections have negotiated terms that no public calculator can model reliably.

From NEPRA’s uniform tariff determinations for ex-WAPDA distribution companies — the FY2025-26 schedule as amended by the January 2026 rationalisation — plus the monthly FCA and quarterly QTA notifications. We update the configuration when notifications land and print the verification date on the page.

A reference number retrieves your actual issued bill rather than calculating one — use our bill check tool for that. This calculator is for estimating before the bill issues, or testing what a change in usage would do.

Estimate First, Then Verify:

A GEPCO bill calculator is most useful before the bill exists — when there is still time to duck under a slab boundary, defend protected status, or shift load off peak hours. Estimate mid-month, adjust, and then confirm the real figure with a bill check once it issues. Rates on this page move with NEPRA’s notifications; we track them so you don’t have to.
