What is the LESCO tariff for 350 units in 2026-27?

A non-protected LESCO consumer using 350 units per month pays roughly Rs 13,000 to Rs 14,500 in total on the 2026-27 tariff, depending on the current FPA and QTR values. Breakdown: base energy charge approximately Rs 8,900 (100 units at Rs 16.48 plus 100 at Rs 21.32 plus 100 at Rs 25.09 plus 50 at Rs 29.04), fixed charge Rs 350, FPA around Rs 1,225 at Rs 3.50 per unit, QTR around Rs 525 at Rs 1.50 per unit, FC surcharge Rs 150, NJ surcharge Rs 35, Electricity Duty Rs 134, GST at 18 percent around Rs 2,050, plus TV fee Rs 35. Use the calculator above with your actual FPA from your last bill for a pinpoint estimate.

What is the difference between protected and non-protected LESCO consumers?

Protected consumers have a six-month average consumption of 200 units or less and pay a uniform lower slab rate (Rs 7.74 per unit for 1 to 100 units, Rs 10.06 per unit for 101 to 200) with no fixed monthly charge. Non-protected consumers cross the 200-unit six-month average and pay progressive slab rates starting at Rs 16.48 per unit plus a monthly fixed charge tier from Rs 75 to Rs 550 depending on how high their monthly usage climbs. Reversion to protected status requires six consecutive months of 200 units or less, so once you cross over you stay non-protected for at least six months.

How does the LESCO slab-crossing warning work?

LESCO slabs are progressive, which means a household using 201 units pays significantly more than one using 200 because the marginal rate jumps from Rs 21.32 to Rs 25.09 on that 1 extra unit, plus the fixed monthly charge tier bumps from Rs 75 to Rs 175. The calculator flags a red warning when your current month consumption is within 10 units of the next slab boundary so you can decide whether to cut non-essential loads (spare AC, geyser, dishwasher) for the last few days of the cycle. Even a 3 to 5 unit reduction can save Rs 500 to Rs 2,000 on the total bill if it keeps you inside the current slab.

Should I opt for the LESCO TOU tariff?

TOU (Time of Use) tariff is only worth it if you can genuinely shift heavy loads out of the 5 PM to 11 PM peak window. TOU peak rate is Rs 39.63 per unit versus off-peak Rs 22.29, a Rs 17.34 gap. If your AC, geyser, washing machine and iron all run during peak hours (typical evening dinner-plus-shower pattern), TOU is more expensive than the standard non-protected tariff. If you can move the geyser and washing machine to late night or early morning and use the AC only sparingly during peak, TOU can save Rs 3,000 to Rs 8,000 per month for high-consumption households. TOU requires a dual meter installed by your LESCO SDO office.

What is the Section 235 withholding tax on LESCO bills?

Section 235 of the Income Tax Ordinance imposes a 7.5 percent withholding tax on electricity bills exceeding Rs 25,000 per month for non-filers of income tax returns. Filers on the FBR Active Taxpayer List (ATL) are exempt from this WHT. On a Rs 30,000 non-filer bill, Section 235 adds Rs 2,250. Filing your FBR return is by far the cheapest way to reduce your monthly electricity bill if you are currently a non-filer with high consumption.

What are FPA and QTR on LESCO bills?

FPA (Fuel Price Adjustment) is a variable per-unit charge NEPRA notifies each month based on the actual cost of fuel used to generate electricity that month versus the reference cost. FPA can be positive (increase) or negative (rebate) and typically ranges Rs -3 to Rs +8 per unit. QTR (Quarterly Tariff Adjustment) is a similar variable charge set once per quarter to true up the actual cost of purchased electricity versus the reference. Both are line items on your LESCO bill, so read the exact values from your last bill and punch them into the calculator for a pinpoint estimate.

What is the LESCO lifeline consumer rate?

Lifeline consumers using 50 units or less per month pay the deeply subsidised rate of Rs 3.95 per unit, no fixed charge, no most surcharges. This is designed for very low-income households and small tenants. If your six-month average stays under 50 units you retain lifeline status. Consuming even 51 units in one month moves you into the 51 to 100 protected slab at Rs 7.74 per unit for that portion.

How do I lower my LESCO bill quickly?

Four fast levers: (1) File your FBR return to eliminate the 7.5 percent Section 235 WHT if you are non-filer with over Rs 25,000 bill. (2) Watch the slab-crossing warning in this calculator and cut usage in the last 3 to 5 days if you are close to the next slab boundary. (3) If your six-month average is close to 200 units, aggressively reduce for 2 to 3 months to drop back into protected status. (4) Switch high-load appliances (geyser, AC) off during peak evening hours or opt for TOU tariff. Beyond these, solar with net metering is the structural fix for consistently high bills.

Where do these LESCO tariff rates come from?

Base tariff slabs are from the NEPRA S.R.O. 46(I)/2026 residential tariff notification effective 13 January 2026, cross-verified against bill.com.pk and lescoebillcheck.pk aggregated summaries. Surcharge amounts (FC Rs 0.43, NJ Rs 0.10, Electricity Duty 1.5 percent, GST 18 percent, TV fee Rs 35, Section 235 non-filer 7.5 percent) are per the same NEPRA notification. FPA and QTR are variable per cycle and must be read from your current LESCO bill for exact accuracy. Confirm any figure at the NEPRA LESCO tariff page before acting on a large payment or dispute.

Does this calculator work for K-Electric, IESCO, MEPCO and other DISCOs?

Not exactly. Each DISCO has slightly different slab rates and surcharge amounts even though the overall structure (protected vs non-protected, FPA plus QTR plus taxes) is similar. LESCO is Punjab. K-Electric is Karachi with its own NEPRA determination. IESCO covers Islamabad and Rawalpindi with different fixed charges. MEPCO covers Multan and southern Punjab. Use our all-DISCO Electricity Bill Calculator for a rough estimate across all 11 utilities; use this LESCO calculator only if you are on the LESCO network for precise numbers.

Free LESCO bill calculator for Lahore Electric Supply Company residential consumers, updated to the NEPRA S.R.O. 46(I)/2026 tariff notification effective January 2026. Handles the three consumer categories: protected (six-month average under 200 units, uniform lower slab rates, no fixed monthly charge), non-protected (six-month average over 200 units, progressive rate slabs starting at Rs 16.48 per unit and climbing to Rs 42.72 per unit above 700 units, plus fixed monthly charges from Rs 75 to Rs 550), and TOU (Time of Use, voluntary opt-in with dual meter, cheaper off-peak rate Rs 22.29 versus peak Rs 39.63 during 5 PM to 11 PM). The killer feature is a live slab-crossing warning that fires when your current month usage is within 10 units of the next slab boundary, so you can decide whether to unplug the geyser or spare AC for the last few days of the cycle to avoid the Rs 4-6 per-unit rate jump plus the Rs 175-350 fixed-charge tier bump that hits when you cross over. The full breakdown includes: slab-by-slab base energy charge, monthly fixed charge, FPA (Fuel Price Adjustment, user-adjustable to match your last bill, typical range Rs -3 to +8 per unit), QTR (Quarterly Tariff Adjustment, user-adjustable), FC surcharge Rs 0.43 per unit, NJ surcharge Rs 0.10 per unit, Electricity Duty 1.5 percent of base energy charge, GST 18 percent on pre-tax total, TV fee Rs 35 fixed, and Section 235 non-filer WHT 7.5 percent on bills over Rs 25,000.

Shift heavy loads off-peak. Rs 17.34 per unit gap between peak and off-peak TOU rates. Run washing machine and geyser after 11 PM.

File your FBR return. Non-filers pay 7.5% extra as Section 235 WHT on bills over Rs 25,000. On a Rs 30,000 bill that is Rs 2,250 saved per month by filing.

Rate source and accuracy

Base tariff slabs verified against NEPRA S.R.O. 46(I)/2026 residential notification effective January 2026, with the February revision under S.R.O. 279(I)/2026 and the quarterly adjustment under S.R.O. 459(I)/2026. NEPRA notifies FPA every month and QTR every quarter, and rates can differ slightly across aggregator sites depending on which cycle they cite.

Get pinpoint accuracy: read the exact FPA and QTR values from your current LESCO bill and enter them above. That gives a number within Rs 100 of the actual bill in almost all cases. If your bill shows a different base per-unit rate than the calculator uses, the NEPRA cycle has shifted; verify at the NEPRA LESCO tariff page. This is an estimate tool. Actual bills may vary due to arrears, adjustments, meter reading errors and cycle-specific NEPRA notifications.

Pick your consumer type: Protected if your six-month average consumption is 200 units or less, Non-protected if higher, or TOU if you have opted into the Time of Use dual-meter tariff.
Enter the units consumed this month, read directly from the LESCO bill (usually labelled Units Consumed or kWh). For TOU, enter peak and off-peak units separately.
Set filer status. Non-filers pay a 7.5 percent Section 235 withholding tax on bills over Rs 25,000; filers do not. Filing your FBR return saves this amount every month.
Adjust FPA and QTR to match the exact per-unit values on your current bill. Defaults are conservative mid-cycle values but NEPRA updates FPA monthly and QTR quarterly.
Read the result. The primary card shows the total payable and effective per-unit rate. Slab-by-slab breakdown table shows exactly which rate applied to which portion of your consumption. Watch for the red slab-crossing warning if your usage is close to the next slab boundary.
Verify against your LESCO bill. Actual bills may vary due to arrears, adjustments, meter reading errors and cycle-specific NEPRA notifications. Confirm the exact number on your official bill or the NEPRA LESCO tariff page before disputing any charges.
