MEPCO Bill for 100 to 700 Units

Last checked 26 September 2026

On a September 2026 bill, 300 units cost an un-protected MEPCO home with a 1 kW sanctioned load an estimated Rs 14,368. That is Rs 9,930 of energy at Rs 33.10 a unit, a Rs 350 fixed charge, the fuel and quarterly adjustments, the federal debt servicing surcharge, 1.5% electricity duty and 18% sales tax. This page gives the same estimate from 100 to 700 units, explains why protected homes pay far less, and shows where one extra unit costs the most.

Estimated MEPCO bills from 100 to 700 units

Each row below is one month's units, read from the meter. The two columns give the estimated total for a protected home and for an un-protected home, worked out from NEPRA's current residential tariff and the adjustments on September 2026 bills.

The totals rest on seven assumptions:

• a sanctioned load of 1 kW, so the fixed charge equals the per-kW rate for the month's slab;
• a normal (non-ToU) meter on the residential tariff A-1, as used by homes below 5 kW;
• the fuel charges adjustment and quarterly adjustment on September 2026 bills, both applied to the same number of units as the month;
• the federal government's debt servicing surcharge of Rs 3.23 a unit, or Rs 0.43 for a protected home, at the rates NEPRA allowed on 30 March 2023;
• provincial electricity duty at 1.5% of energy and fixed charges, as printed on 2026 MEPCO bills;
• general sales tax at 18% on the total of energy, fixed charges, adjustments, the surcharge and the duty;
• no income tax, arrears, installments or late payment surcharge.

The protected column stops at 200 units because NEPRA's protected rates cover only the first 200 units. A month above 200 is billed at un-protected rates.

Each common amount also has its own page with the full line-by-line bill, the slab it falls in and the next slab edge:

• MEPCO Bill for 100 Units
• MEPCO Bill for 150 Units
• MEPCO Bill for 200 Units
• MEPCO Bill for 250 Units
• MEPCO Bill for 300 Units
• MEPCO Bill for 400 Units
• MEPCO Bill for 500 Units
• MEPCO Bill for 700 Units

What does one unit cost?

One unit costs Rs 10.54 to Rs 47.20 before adjustments and tax, depending on your category and the slab your month's total falls in. Lifeline homes pay Rs 3.95 or Rs 7.74. Every slab is listed in the MEPCO tariff 2026 unit rates.

The slab rate is only part of the price. On a September 2026 bill, spreading the fixed charge, the fuel and quarterly adjustments, the debt servicing surcharge and sales tax across the month gives a 1 kW home these all-in costs per unit:

At 300 units, for example, the Rs 33.10 slab rate becomes Rs 47.89 a unit on that bill once the fixed charge, the adjustments, the surcharge and sales tax are added in. The all-in figure moves each month with the adjustments.

Why do protected homes pay so much less?

Protected homes pay lower NEPRA rates, keep the lowest rate on their first 100 units, and pay a smaller fixed charge up to 100 units. An un-protected home pays one higher rate on every unit of the month.

Three differences in NEPRA's tariff create the gap:

1. Lower unit rates. Protected homes pay Rs 10.54 for units 1 to 100 and Rs 13.01 for units 101 to 200. Un-protected homes pay Rs 22.44 and Rs 28.91 for the same slabs.
2. The previous-slab benefit. NEPRA gives only protected homes the benefit of one previous slab. At 200 units, a protected home still pays Rs 10.54 on its first 100 units, while an un-protected home pays Rs 28.91 on all 200.
3. A smaller fixed charge at low use. Up to 100 units, a protected home pays Rs 200 per kW against Rs 275 for an un-protected home. From 101 to 200 units, both pay Rs 300 per kW.

The fuel and quarterly adjustments cost both homes the same per unit, but the federal debt servicing surcharge is Rs 0.43 a unit for a protected home against Rs 3.23 for an un-protected one. Sales tax is 18% of a larger sum on the un-protected bill, so the gap widens after tax.

The protected rates are subsidised. In figures the Ministry of Energy presented to NEPRA in February 2026, covering all former WAPDA distribution companies together rather than MEPCO alone, supplying a unit to homes using up to 300 units cost Rs 36.13, while protected homes paid an average of Rs 11.05. Who qualifies, and how one month above 200 units ends it, is set out in the protected consumer rules and six-month test.

Worked example: 200 units and the jump at 201

At 200 units, the category decides most of the bill. This is the arithmetic for a home with a 1 kW sanctioned load, using NEPRA's current rates.

Protected, 200 units. The first 100 units cost 100 × Rs 10.54 = Rs 1,054 and the next 100 cost 100 × Rs 13.01 = Rs 1,301, so energy is Rs 2,355. The fixed charge is 1 kW × Rs 300 = Rs 300. Energy plus fixed charge: Rs 2,655.

Un-protected, 200 units. All 200 units cost Rs 28.91 each, so energy is Rs 5,782. With the same Rs 300 fixed charge, the sum is Rs 6,082.

Any home at 201 units. The month now falls in the 201-300 slab, which only the un-protected rates cover. All 201 units cost Rs 33.10 each, or Rs 6,653.10, and the fixed charge rises to Rs 350. The sum is Rs 7,003.10.

On a September 2026 bill, the month's fuel and quarterly adjustments, the debt servicing surcharge and 18% sales tax turn these three sums into estimated totals of Rs 3,890, Rs 8,655 and Rs 9,765. The 201st unit therefore adds about Rs 1,110 to an un-protected home's bill and about Rs 5,880 to a protected home's. The protected home then stays on un-protected rates until it has six months in a row at 200 units or less again.

Where does one more unit cost the most?

For an un-protected home, one more unit costs the most at the 700-unit edge: going from 700 to 701 units adds Rs 3,792 at 1 kW, before adjustments and tax. Every edge adds something, because the whole month moves to the higher rate.

The table sets energy plus fixed charges at each slab edge beside the figure one unit above it, for a 1 kW un-protected home:

The 700-unit edge stands out because the rate on every unit rises from Rs 41.85 to Rs 47.20. A month that ends a few units past any edge costs noticeably more than one that stops just short of it.

Why your bill can differ from these totals

A real bill can differ because the fuel adjustment uses an earlier month's units, your sanctioned load may not be 1 kW, and some charges are left out of the estimates.

The fuel adjustment uses an earlier month's units

NEPRA's decision of 4 September 2026 puts the fuel charges adjustment for July 2026, Rs 2.0581 a unit, on September 2026 bills, charged on the units billed for July. A home billed for 350 units in July 2026 and 250 in September pays the September fuel adjustment on 350 units: 350 × Rs 2.0581 = Rs 720.34. The rate changes every month; see this month's MEPCO fuel and quarterly adjustment rates.

Your sanctioned load

The fixed charge is the per-kW rate multiplied by your sanctioned load. At 300 units, a 2 kW home pays 2 × Rs 350 = Rs 700 instead of Rs 350, before sales tax. The rate for each slab is explained in MEPCO fixed charges per kW.

Charges the estimates leave out

These items appear on some bills but not in the totals above:

• income tax of 7.5% on monthly bills of Rs 25,000 or more when the consumer is not on FBR's Active Taxpayers List, covered under taxes on a MEPCO bill;
• arrears, installments and deferred amounts from earlier bills;
• the late payment surcharge added after the due date;
• any correction or detection charge added by MEPCO.

A reading period longer than a month

NEPRA's tariff terms define a billing month as 31 days or less from the last meter reading. If a reading period runs longer than the calendar month, the units are prorated to that month's days to decide the slab.

Estimate the bill for your own home

To estimate your own bill, enter your units, category and sanctioned load in the bill calculator. Every figure it needs is printed on your bill.

1. Open your latest bill with the MEPCO online bill check and your 14-digit reference number.
2. Note your units and load. Units are the present reading minus the previous one, and the sanctioned load is shown in kW.
3. Check your category. On a normal meter, six months in a row at 200 units or less in the history box means you are billed as protected.
4. Run the estimate in the MEPCO bill calculator, which adds this month's adjustments, the debt servicing surcharge and sales tax.
