MEPCO Bill Calculator: Estimate Your Bill from Units (August 2026)

Updated: August 2026

Run 300 units this month on a 2 kW MEPCO domestic connection and your August 2026 bill lands at about Rs 13,287 — Rs 9,930 of it electricity, the rest the FC surcharge, the SRO 279 fixed monthly charge, electricity duty and GST, softened by a quarterly credit of Rs 1.9857 per unit that runs through August bills. Cross into 301 units and the same house owes about Rs 14,658, because MEPCO bills the whole month at the slab your total lands in. The MEPCO bill calculator below does that arithmetic for you: enter your units and it rebuilds the bill line by line, from slab rate and FC surcharge through the QTR credit, electricity duty, GST and the current FPA — the same way MEPCO‘s billing system computes it for more than seven million connections across South Punjab, from Multan and Khanewal down to Sahiwal, Vehari, Bahawalpur, DG Khan and Rahim Yar Khan.

How to use the MEPCO bill calculator

The widget opens with MEPCO preselected, so it works out of the box whether your bill comes from Multan city, Muzaffargarh, Layyah, Lodhran or anywhere else in MEPCO’s 13 districts.

1. Pick your consumer type. Protected means your usage stayed at or under 200 units for six straight months; unprotected is everyone else; lifeline covers small connections (up to 1 kW) using no more than 100 units. Your bill prints the status, and our guide to protected vs unprotected consumers shows exactly where to look.
2. Enter your units. Take them from the meter (today’s reading minus the previous bill’s reading) or from the units-consumed box on any recent bill.
3. Check your sanctioned load. Since 12 February 2026 the fixed monthly charge is billed per kW of sanctioned load, so the “Load” figure on your bill matters: a 2 kW home pays twice the per-kW rate, a 3 kW home three times. The box defaults to 2 kW; set it to your own.
4. Read the result. Every row matches a row on the printed bill, and the teal strip at the bottom shows your effective cost per unit — usually an eye-opener.
5. Flip the TOU switch if you have a peak/off-peak meter. The slab inputs swap for peak and off-peak unit boxes at MEPCO’s time-of-use rates.
6. Crossed Rs 25,000? A checkbox appears for the 7.5% Section 235 advance income tax, which applies only if you are not on FBR’s Active Taxpayers List. Filers skip it.

The calculator also warns you about status downgrades. Type 230 units with “Protected” selected and it will bill you at unprotected rates with a note explaining why: crossing 200 units costs you protected status for the month and restarts the six-month clock.

MEPCO slab rates in force for August 2026

MEPCO charges the uniform consumer-end tariff the federal government notifies for all ex-WAPDA DISCOs: there is no separate “MEPCO rate”. The schedule below reflects SRO 279(I)/2026, notified by the Ministry of Energy on 12 February 2026 and in force since: rates up to 300 units are unchanged from the 1 July 2025 schedule, the slabs above 300 units were trimmed by roughly Rs 1.5 per unit, and a new fixed monthly charge of Rs 200–675 per kW of sanctioned load was added. A NEPRA review petition against the fixed charges (filed March 2026) was still pending as of August 2026, and a further government tariff package was under discussion in late July 2026, so treat these as the rates as of August 2026. The complete category-wise schedule, commercial and agricultural rates included, is in our MEPCO per unit price guide.

The fixed monthly charge — new since February 2026

SRO 279(I)/2026 added a charge that has nothing to do with how many units you burn: a fixed monthly charge billed per kW of sanctioned load, set by the slab your month lands in and levied even if you use nothing. GST then sits on top of it. In the calculator it appears as its own line once you enter a sanctioned load. The per-kW rate climbs with the landing slab:

For a 2 kW unprotected home landing in 201–300 units, that is Rs 350 × 2 = Rs 700 added to the bill; nudge into 301–400 and the fixed charge itself steps up to Rs 400 × 2 = Rs 800. Two things to keep in mind: lifeline consumers pay no fixed charge — a Rs 75 single-phase / Rs 150 three-phase minimum charge applies instead, and only when the energy charge falls below it — and on a TOU (5 kW+) connection the fixed charge is Rs 675 per kW billed on the greater of half your sanctioned load or your recorded maximum demand (MDI). The whole fixed-charge regime is under a NEPRA review petition filed in March 2026, so it may yet change.

The landing-slab rule — why one unit can cost Rs 1,371

Since the subsidy re-targeting of 2022, an unprotected domestic consumer gets no previous-slab benefit. Your whole month’s consumption is billed at the rate of the slab your total lands in. Use 300 units and all 300 are charged at Rs 33.10. Use 301 and all 301 are charged at Rs 36.46 — the first 300 do not stay at the cheaper rate.

The rupee effect is brutal at slab boundaries. With August 2026 adjustments applied and a 2 kW load, the calculator puts a 200-unit unprotected bill at Rs 8,011.56 and a 201-unit bill at Rs 9,174.77: that single unit costs Rs 1,163.21. At the next boundary it is worse — 300 units comes to Rs 13,286.85 and 301 units to Rs 14,657.69, a jump of Rs 1,370.84. Part of that jump is the fixed charge stepping up a slab too (Rs 350/kW to Rs 400/kW). This is why South Punjab’s June-to-August AC season pushes so many households into bill shock, and why shaving even a handful of units at month-end can pay for itself many times over.

Protected consumers are the exception: they keep the benefit of one previous slab, so at 200 units the first 100 still bill at Rs 10.54 and only the rest at Rs 13.01. A 200-unit protected bill works out to Rs 3,907.05 — the unprotected house next door pays Rs 8,011.56 for identical usage.

Worked example: 300 units, unprotected

Assumptions, stated plainly: this is an August 2026 MEPCO bill on a 2 kW single-phase domestic connection, so it carries the Jun–Aug QTR credit of Rs 1.9857 per unit and an FPA of +Rs 0.3364 per unit (the May fuel adjustment, still the last one notified — NEPRA heard the June petition on 29 July and reserved its decision). The SRO 279 fixed charge for the 201–300 landing slab is Rs 350 per kW, so Rs 700 for 2 kW. Electricity duty is taken at 1.5%, the usual Punjab domestic rate.

Effective cost: Rs 44.29 per unit. Enter 300 units with “Unprotected” selected and the sanctioned load at 2 kW in the calculator above and you get precisely these figures, row for row.

Calculate a MEPCO bill by hand, step by step

If you want the machinery rather than the widget — for a spreadsheet, or to audit a printed bill — here is the full sequence, using the same 300 units.

Step 1 — find the landing slab. 300 units falls in the 201–300 band, so every unit bills at Rs 33.10. Energy charges: 300 × 33.10 = Rs 9,930.00.

Step 2 — add the FC surcharge. A flat Rs 3.23 per unit debt-servicing surcharge applies to everyone except lifeline consumers: 300 × 3.23 = Rs 969.00.

Step 3 — apply the QTR adjustment. June, July and August 2026 bills carry a NEPRA-approved credit of Rs 1.9857 per unit: 300 × 1.9857 = Rs 595.71 subtracted. Running total (the “cost of electricity”): 9,930.00 + 969.00 − 595.71 = Rs 10,303.29.

Step 4 — add the fixed monthly charge. Since SRO 279(I)/2026, a fixed charge is billed per kW of sanctioned load, at the rate set by the landing slab. The 201–300 slab is Rs 350 per kW, and this is a 2 kW connection: 350 × 2 = Rs 700.00. Lifeline consumers pay no fixed charge.

Step 5 — electricity duty. The provincial levy, 1.5% for Punjab domestic connections, is charged on the cost of electricity (not the fixed charge): 1.5% × 10,303.29 = Rs 154.55.

Step 6 — GST. Sales tax at 18% is charged on the cost of electricity plus duty plus the fixed charge, so the base is 10,303.29 + 154.55 + 700.00 = 11,157.84, and GST is Rs 2,008.41. This is why the GST line always looks bigger than 18% of your energy cost — it taxes the surcharge, the fixed charge and duty too. Every one of these lines is unpacked in our guide to taxes on electricity bills in Pakistan.

Step 7 — FPA, with its own tax lines. The fuel price adjustment rides as a separate block: 300 × 0.3364 = Rs 100.92, plus duty on it (Rs 1.51) and GST on it (Rs 18.17). How the monthly FCA becomes your FPA line two months later is covered in our FPA guide.

Step 8 — total. 10,303.29 + 700.00 + 154.55 + 2,008.41 + 100.92 + 1.51 + 18.17 = Rs 13,286.85 payable within the due date, or Rs 14,615.54 after it (a 10% late payment surcharge).

One habit worth copying from the billing system: round every line to two decimal places before summing. Chain the whole thing through a phone calculator without rounding and your answer can drift a rupee or two from the printed bill.

MEPCO peak hours and TOU billing

If your connection has a time-of-use meter (common on three-phase and higher sanctioned loads), slabs stop mattering. Every unit is priced by when you used it, and there is no protected or unprotected category. For MEPCO and the other ex-WAPDA DISCOs the residential TOU rates are Rs 46.85 per peak unit and Rs 34.53 per off-peak unit, per SRO 279(I)/2026 — the off-peak rate dropped by about Rs 5.5 from the previous schedule, so shifting load off-peak now saves more than it used to.

The peak window is four hours long all year; it just slides with the seasons:

So in August, every unit between 7 PM and 11 PM — prime AC hours in Multan — costs Rs 12.32 more than the same unit at midnight. Flip the TOU switch in the calculator and it prices each bucket separately: on a 5 kW connection, a 600-unit month split as 180 peak and 420 off-peak units gives energy charges of Rs 22,935.60 (8,433.00 peak + 14,502.60 off-peak) and a total bill of Rs 30,596.59 with August’s adjustments — including the Rs 675/kW TOU fixed charge on 2.5 kW (half the load) — for an effective Rs 50.99 per unit. Shifting the water pump, washing machine and iron past 11 PM is the whole game; our peak hours guide has the savings math.

Why your estimate can differ from the printed bill

The calculator mirrors MEPCO’s tariff arithmetic, but a printed bill can still land a little different. The usual suspects:

• A new FCA can be notified any day. The June fuel adjustment (about Rs 1.20 per unit requested) was heard by NEPRA on 29 July 2026 and the decision is reserved. The calculator carries +Rs 0.3364, the last FCA actually notified; if the new one lands on August bills, add roughly Rs 1.20 per unit plus its GST.
• The QTR credit expires with August bills. The Rs 1.9857 credit covers June–August 2026 only, and lifeline, prepaid and incremental-package consumers never receive it. September estimates will change.
• Arrears and instalments. Any unpaid balance, deferred amount or instalment plan appears on the bill but no calculator can know about it.
• Meter rent and service rent. Small fixed charges some MEPCO bills carry; deliberately excluded here, usually under Rs 50.
• The fixed monthly charge scales with your exact sanctioned load. This page applies SRO 279(I)/2026, which bills a fixed charge of Rs 200–675 per kW of sanctioned load (set by your landing slab), with GST on top. Enter a load that differs from the “Load” figure on your bill and this line — and its GST — will be off. A NEPRA review petition against these charges (filed March 2026) was still pending as of August 2026, so the line could yet change or be rolled back.
• Electricity duty varies by province and category. We assume 1.5%; your bill’s ED line may use a slightly different percentage.
• Your billing cycle is not exactly 30 days. A 33-day reading gap can push a 290-unit household over 300 units — and with the landing-slab rule, one slab is real money.
• Protected status is MEPCO’s record, not your memory. If any of the last six months crossed 200 units, you bill as unprotected even if this month is modest.

Get the inputs right and the estimate typically lands within a few percent of the printed total — close enough to spot a wrong meter reading or a detection unit charge immediately.

FAQs

How do I calculate my MEPCO bill from units?

Multiply all your units by the rate of the slab your total lands in, add the Rs 3.23 per unit FC surcharge, subtract the QTR credit of Rs 1.9857 per unit (on June–August 2026 bills), add the SRO 279 fixed charge (Rs 200–675 per kW of sanctioned load), add electricity duty at about 1.5%, then add 18% GST on all of it. Any FPA rides as a separate line with its own duty and GST. The calculator on this page runs those steps in that exact order.

What is the MEPCO per-unit rate in August 2026?

For unprotected domestic consumers, from Rs 22.44 (up to 100 units) to Rs 47.20 (above 700 units), with the whole month billed at the landing slab. Protected consumers pay Rs 10.54 and Rs 13.01, lifeline consumers Rs 3.95 or Rs 7.74. These are the uniform government-notified rates under SRO 279(I)/2026; MEPCO has no separate schedule. The FC surcharge, the fixed monthly charge, duty and GST then sit on top.

Why does the calculator charge all my units at one slab rate?

Because that is how unprotected domestic billing works: there is no previous-slab benefit. At 301 units, all 301 bill at Rs 36.46 — the first 300 do not stay at lower rates. Only protected consumers, who have kept usage at or under 200 units for six straight months, retain the benefit of one previous slab.

How do I know if I am protected or unprotected on MEPCO?

Check any recent bill: the tariff line prints your category. If your usage stayed at or under 200 units in each of the last six months, you are protected; a single month above 200 moves you to unprotected rates and restarts the six-month clock.

Does this calculator include the FPA and QTR adjustment?

Yes. It applies the Rs 1.9857 per unit QTR credit running on June–August 2026 bills (lifeline, prepaid and incremental-package consumers excluded) and an FPA of +Rs 0.3364 per unit, the May fuel adjustment that was the last one notified. NEPRA heard the June FCA petition of about Rs 1.20 per unit on 29 July 2026 and reserved its decision, so August bills may carry a higher FPA once notified.

Why is my actual MEPCO bill higher than the estimate?

The common reasons are arrears or instalments on the account, meter rent, a newly notified FCA, a longer-than-30-day reading cycle pushing you into a higher slab, a detection charge, or losing protected status without realising it. Compare the estimate line by line with the printed bill and the difference usually identifies itself.

Is there income tax on MEPCO domestic bills?

Only when the month’s bill exceeds Rs 25,000 and the account holder is not on FBR’s Active Taxpayers List — then 7.5% advance income tax under Section 235 applies. Filers are exempt, and the calculator adds it only when you tick the checkbox that appears above that threshold.

What are MEPCO peak hours in August 2026?

7 PM to 11 PM, the June–August window. The peak block is always four hours: it moves to 6–10 PM in September–November and March–May, and 5–9 PM in December–February. Peak rates only affect connections with a time-of-use meter; ordinary single-phase slab consumers pay the same rate around the clock.
