QESCO Bill Calculator: From Units to Total Bill in Seconds (2026)

Updated: August 2026

A 300-unit QESCO bill in the August 2026 cycle comes to Rs 13,286.85 for an unprotected domestic consumer on a 2 kW connection: Rs 9,930 of actual electricity plus roughly Rs 3,953 in the new fixed charge, FC surcharge, duty, GST and fuel adjustment, softened by a Rs 595.71 quarterly credit. That works out to Rs 44.29 per unit once everything lands, well above the Rs 33.10 slab rate you might expect. Your own number turns on four things: how many units you burned, whether your connection counts as protected or unprotected, your sanctioned load in kW (which now sets a separate fixed monthly charge), and whether you run a normal meter or a peak/off-peak (TOU) one. The QESCO bill calculator below takes those inputs and rebuilds your bill the way QESCO’s billing system does it, line by line, on the rates in force this month.

It works for any QESCO domestic connection across Balochistan, from Quetta and Pishin to Gwadar, Turbat, Khuzdar, Sibi, Zhob and Loralai. On a different company? Switch the DISCO in the first dropdown, or start from our all DISCOs hub.

How to use the QESCO bill calculator

Four inputs, one straight answer:

1. Consumer type. Choose Protected only if your usage stayed at or under 200 units in each of the last six months. Otherwise you’re Unprotected, which covers most homes in Quetta once the summer coolers and winter heaters are running. Lifeline is for a small sanctioned load using up to 100 units, common in the smaller towns and villages across Balochistan. If you aren’t sure, our protected vs unprotected guide shows exactly where to look on your bill.
2. Units. Take them from the meter (today’s reading minus last month’s billed reading) or straight from the UNITS CONSUMED box on any recent QESCO bill.
3. Sanctioned load (kW). Printed on your bill as “Load” or “Sanctioned Load”. Since 12 February 2026 the fixed monthly charge is billed per kW of this figure, so a 2 kW home pays twice the table rate. The calculator defaults to 2 kW; lifeline consumers pay no fixed charge.
4. TOU toggle. Flip it only if your bill shows separate peak and off-peak lines, then type in both figures.

When your total crosses Rs 25,000, a checkbox appears for the 7.5% Section 235 advance income tax. Tick it only if you are not on FBR’s Active Taxpayers List; filers skip it. The tool also flags when your inputs change your status. Enter “protected” with 250 units and it bills you at unprotected rates, because that is exactly what QESCO does.

The result table follows the order of a printed QESCO bill: energy charges first, then the FC surcharge, the quarterly adjustment (green when it’s a credit), the fixed monthly charge, duty, GST, and the month’s fuel adjustment with its own taxes. Two figures at the bottom repay a second look. The after-due-date amount adds the 10% late payment surcharge, so it is what a missed due date costs. The effective per-unit figure tells you what your electricity really costs once every add-on lands, and comparing it at different unit levels is the quickest way to spot a slab cliff before you walk off it.

QESCO slab rates for August 2026

QESCO bills domestic consumers on the GoP-applicable consumer-end schedule notified in SRO 279(I)/2026 (Ministry of Energy, 12 February 2026). That notification left the slabs up to 300 units untouched, trimmed the rates above 300 units by roughly Rs 1.5 a unit, and added a per-kW fixed monthly charge. These are the consumer-end rates NEPRA‘s schedule applies to bills, verified against the official DISCO tariff pages and the SRO itself, and the same figures the calculator uses (as of August 2026):

The full QESCO tariff, including commercial, industrial and agricultural categories, is in our QESCO per unit price breakdown.

The fixed monthly charge (new since February 2026)

SRO 279(I)/2026 added a fixed monthly charge on top of the per-unit rates. It is billed per kW of your sanctioned load, at a rate set by the slab your month lands in, and it applies even in a month you burn nothing. GST is charged on it like any other line. Lifeline consumers are exempt (they face a small minimum charge of Rs 75 single-phase / Rs 150 three-phase instead, which only bites when the energy charge falls below it).

So a 2 kW unprotected home in Quetta landing in the 201–300 slab pays Rs 350 × 2 = Rs 700 in fixed charges alone, before a single unit is priced. TOU connections (5 kW and up) pay Rs 675 per kW on whichever is higher: 50% of the sanctioned load or the month’s recorded maximum demand (MDI). A NEPRA review petition against these charges, filed in March 2026, was still pending as of August 2026.

The landing slab rule — the part most calculators get wrong

If you’re unprotected, QESCO does not charge your first 100 units at Rs 22.44, the next 100 at Rs 28.91, and so on. Since the subsidy re-targeting, unprotected consumers get no previous-slab benefit: the whole month is billed at the rate of the slab your total lands in. Use 300 units and all 300 cost Rs 33.10 each. Use 301 and all 301 cost Rs 36.46 each.

Only protected consumers keep the old benefit, and only one slab deep. Their first 100 units stay at Rs 10.54 even when the total reaches 200.

This is why the 200-unit line is the most expensive doorstep in Pakistan. A protected home at exactly 200 units pays Rs 3,907.05 this month on a 2 kW connection. Cross to 201 units and the same home is billed unprotected at the landing slab: Rs 9,174.77. That one extra unit costs Rs 5,267.72, because the energy reprices and the fixed charge steps up a slab, and the six-month protected clock restarts on top.

Worked example: 300 units, unprotected

Here is exactly what the calculator produces for 300 units, unprotected, on a 2 kW connection, using August 2026 assumptions: the Jun–Aug quarterly credit of Rs 1.9857 per unit, the SRO 279 fixed charge of Rs 350 per kW, the FPA of +Rs 0.3364 carried from the May fuel adjustment, and the ~1.5% electricity duty.

Effective cost: Rs 44.29 per unit, against a printed slab rate of Rs 33.10. The gap is the fixed charge plus the tax stack, decoded line by line in our guide to taxes on your electricity bill.

Calculate your QESCO bill by hand

Want to see the machinery? This is the exact order QESCO’s billing system uses, with each line rounded to two decimals before summing, the way printed bills do. We’ll run 150 units on a protected connection with a 2 kW sanctioned load:

1. Energy charges. Protected keeps one previous slab: 100 × Rs 10.54 + 50 × Rs 13.01 = Rs 1,054.00 + Rs 650.50 = Rs 1,704.50. (Unprotected? Multiply all your units by the landing-slab rate instead.)
2. FC surcharge. 150 × Rs 3.23 = Rs 484.50. Everyone pays this except lifeline consumers.
3. QTR adjustment. 150 × −Rs 1.9857 = −Rs 297.85 this quarter. Add the three lines so far and you get Rs 1,891.15, which the bill calls your cost of electricity.
4. Fixed monthly charge. Protected, 101–200 slab: Rs 300/kW × 2 kW = Rs 600.00. Billed even at zero use; lifeline consumers are exempt.
5. Electricity duty. 1.5% × Rs 1,891.15 = Rs 28.37.
6. GST. 18% × (Rs 1,891.15 + Rs 28.37 + Rs 600.00) = Rs 453.51. Yes, GST is charged on the duty and the fixed charge too.
7. FPA, with its own duty and GST. 150 × Rs 0.3364 = Rs 50.46, plus ED of Rs 0.76 and GST of Rs 9.08 on that amount.
8. Total. Rs 1,891.15 + 600.00 + 28.37 + 453.51 + 50.46 + 0.76 + 9.08 = Rs 3,033.33 within the due date, Rs 3,336.66 after it.

That protected home pays an effective Rs 20.22 per unit. The identical 150 units on an unprotected connection come to Rs 6,185.68, more than double, from the same meter reading.

A note on Balochistan’s agricultural tube-wells

QESCO carries a load no other DISCO does: tens of thousands of agricultural tube-wells irrigating Balochistan’s orchards and fields, from the apple belt around Pishin and Mastung to the farmland of Kalat and Nasirabad. These connections are billed on a separate, heavily subsidised agricultural tariff under a long-standing federal-provincial arrangement, not the domestic slabs this page uses, so a tube-well’s household estimate here will not match its bill. Check the category printed on your bill and use the agricultural rate from our QESCO per unit price breakdown instead.

What the calculator shows at common usage levels

For a quick sense of scale before you type anything, here is what the QESCO bill calculator returns this month at round unit counts, all add-ons included, on a 2 kW connection:

Protected totals stop at 200 units because protection itself stops there. From 500 units up, the bill crosses the Rs 25,000 line, so non-filers pay 7.5% on top of the figures shown. Notice how the per-unit cost climbs with usage: heavy months are hit twice, once by the higher landing slab and again by the fixed charge and taxes that scale with it. A larger sanctioned load lifts every unprotected total further, since the fixed charge is billed per kW.

QESCO peak hours and TOU billing

If you have a time-of-use meter, slabs don’t apply at all. Every unit is billed at one of two flat rates depending on the clock: currently Rs 46.85 per unit in peak hours and Rs 34.53 off-peak for QESCO residential consumers, per the SRO 279(I)/2026 schedule (residential TOU applies at 5 kW and above). That leaves a gap of Rs 12.32 on every unit, wider than under the previous schedule, so shifting load off the evening window pays off more than before. The peak window is four hours, all year, but it moves with the season:

Flip the calculator’s TOU switch and enter both readings. A Quetta TOU home using 180 peak and 420 off-peak units on a 5 kW connection gets an energy charge of Rs 22,935.60 and a total of Rs 30,596.59 this month, including a Rs 1,687.50 fixed charge (Rs 675/kW on 50% of the sanctioned load). Every unit you move out of the 7–11 PM window saves Rs 12.32 before taxes; the timing tricks are in our peak hours guide.

Why the estimate can differ from your printed bill

The calculator is built to match QESCO’s arithmetic, but four things can move the printed number:

The pending fuel adjustment. August bills were calculated while NEPRA’s decision on the June FCA — about Rs 1.20 per unit requested, heard on 29 July — was still reserved. If it is approved, it replaces the +Rs 0.3364 line, a net addition of roughly Rs 0.86 per unit plus its GST. How the monthly true-up works is covered in our FPA guide.

The quarterly credit expires. The −Rs 1.9857 QTR credit runs on June, July and August 2026 bills only. From September, expect that green line to shrink or vanish, which alone adds about Rs 700 to a 300-unit bill.

Small fixed lines and the fixed-charge review. Meter rent and service rent (usually a few dozen rupees) are excluded, as are arrears, instalments and adjustments carried from previous months. The calculator does apply the SRO 279(I)/2026 fixed monthly charge (Rs 200–675 per kW of sanctioned load), so make sure the sanctioned-load figure you enter matches the “Load” printed on your bill; get that wrong and the fixed line, plus the GST on it, will be off. That charge is also the subject of a NEPRA review petition filed in March 2026, still pending as of August 2026. If it is struck down or revised, printed bills will diverge from this estimate.

Your reading date. QESCO’s billing cycle isn’t exactly 30 days, and long distances between Balochistan towns mean reading dates can slip. A 33-day reading can push your total into the next slab, and with the landing-slab rule that reprices every unit of the month.

FAQs

How do I calculate my QESCO bill from units?

Multiply your units by the slab rate your total lands in (Rs 33.10 for 201–300 units, unprotected), add the Rs 3.23 per unit FC surcharge, subtract this quarter’s Rs 1.9857 per unit credit, add the SRO 279 fixed monthly charge (Rs 275–675 per kW of sanctioned load for unprotected homes), add 1.5% electricity duty, then 18% GST on all of it, then the month’s FPA with its own duty and GST. The calculator on this page runs the whole chain in one step.

What is the QESCO per unit price in August 2026?

Domestic rates run from Rs 3.95 (lifeline, up to 50 units) to Rs 47.20 (above 700 units). The most common brackets are Rs 22.44, Rs 28.91, Rs 33.10 and Rs 36.46 for unprotected homes using 100–400 units. With the FC surcharge, the SRO 279 fixed charge, duty, GST and adjustments, the effective cost this month runs roughly 30–35% above the slab rate for a mid-size unprotected home (300–700 units), and proportionally more on small bills, where the per-kW fixed charge is spread over fewer units.

Why did 201 units cost so much more than 200?

Crossing 200 units does two things at once: it ends protected status for the month, and the landing-slab rule reprices every unit at the higher rate. A protected home pays Rs 3,907.05 for 200 units this month (2 kW connection); at 201 units the bill jumps to Rs 9,174.77. Staying under 200 for six straight months is the single biggest saving available to a QESCO household.

Am I a protected or unprotected QESCO consumer?

You’re protected only if your consumption stayed at or under 200 units in each of the last six months. One month above 200 moves you to unprotected rates and restarts the six-month clock. Your bill’s tariff box shows A-1(01) style codes and the applied rates; comparing your 1–100 unit rate against Rs 10.54 (protected) or Rs 22.44 (unprotected) tells you instantly.

Does the QESCO bill calculator cover agricultural tube-well connections?

No. This calculator estimates domestic household bills on the SRO 279 slabs. Agricultural tube-wells across Balochistan are billed on a separate, heavily subsidised agricultural tariff under a long-standing federal-provincial arrangement, so a tube-well bill will not match the household estimate. Check the category printed on your bill, and use the agricultural rate from our QESCO per unit price breakdown instead.

What are QESCO’s peak hours right now?

7:00 to 11:00 PM through August 2026. The window shifts to 6:00–10:00 PM in the shoulder months (March–May and September–November) and 5:00–9:00 PM in winter (December–February). Peak units cost Rs 46.85 against Rs 34.53 off-peak, so the four-hour window is where a TOU bill is won or lost.

Why is my printed QESCO bill different from this estimate?

The usual suspects: a newly notified fuel adjustment the calculator’s month hasn’t caught up with, arrears or instalments on your account, meter rent, or a reading period longer than 30 days pushing you into the next slab. If the gap is large, pull your actual bill from the QESCO bill check service and compare it line by line against the breakdown above.
