What is the K-Electric tariff for 400 units in 2026-27?

A non-protected K-Electric consumer using 400 units per month pays roughly Rs 17,500 to Rs 19,000 in total on the 2026-27 tariff. Base energy charge is approximately Rs 12,600 (100 at Rs 18.13, 100 at Rs 23.45, 100 at Rs 30.30, 100 at Rs 36.46) plus Rs 400 fixed charge, FPA around Rs 1,680 at Rs 4.20 per unit, QTR around Rs 700 at Rs 1.75 per unit, FC and NJ surcharges roughly Rs 212, Electricity Duty about Rs 189, GST at 18 percent about Rs 2,835, plus TV fee Rs 35. Filer total lands roughly Rs 18,650. Use the calculator above with your actual FPA from your last bill for pinpoint accuracy.

How does K-Electric tariff compare to LESCO for the same consumption?

K-Electric residential rates run 5 to 10 percent higher than LESCO on the upper slabs due to K-Electric's own generation cost structure (it runs its own power plants unlike WAPDA DISCOs). For a 400-unit non-protected household: K-Electric total lands roughly Rs 18,650 while LESCO on the same profile lands roughly Rs 16,000, a difference of about Rs 2,600 per month. Protected consumer rates are similar across both utilities at the lower end, diverging as consumption climbs. K-Electric's fixed charge structure is also different (small Rs 100-650 tiers versus LESCO's Rs 75-550 range).

How does the K-Electric TOU tariff work?

K-Electric TOU (Time of Use) tariff splits residential rates into peak (6 PM to 10 PM in summer, shifting to 5 PM to 9 PM in winter) and off-peak (all other hours). Peak rate is roughly Rs 42.85 per unit, off-peak Rs 24.15, a Rs 18-19 gap. Requires a dual meter installed by the KE Integrated Business Centre and voluntary opt-in. Worth it only if you can consistently shift heavy loads (geyser, washing machine, AC on lower thermostat, iron) out of the 6 PM to 10 PM window. If your evening usage is heavy (typical Karachi household running AC plus geyser plus cooking simultaneously in the peak window), TOU is more expensive than the standard tariff.

How do I qualify for K-Electric protected consumer status?

Protected status requires a six-month rolling average consumption of 200 units per month or less. K-Electric's system tracks this automatically on your account. If your six-month average crosses 200 units in any billing cycle, you shift to non-protected rates going forward. Reversion back to protected requires six consecutive months of 200 units or less. Note that K-Electric applies a Rs 300 fixed charge on the 101-200 protected slab, unlike LESCO which has no fixed charge on protected consumers.

What is the K-Electric 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 the same rate as other DISCOs since it is set uniformly by NEPRA for very low-income households across Pakistan. Consuming even 51 units in one month moves that portion into the protected 51-100 slab at Rs 7.74 per unit for that month, but lifeline eligibility persists as long as the 6-month average stays under 50.

What is the Section 235 non-filer WHT on K-Electric bills?

Section 235 of the Income Tax Ordinance imposes a 7.5 percent withholding tax on domestic 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. On a Rs 30,000 K-Electric non-filer bill, Section 235 adds Rs 2,250. Karachi has a higher-than-average share of high-consumption households (larger apartments, longer AC usage due to heat and humidity), so filing your FBR return has particularly meaningful impact on K-Electric bills.

Where do these K-Electric tariff rates come from?

Base tariff slabs verified against NEPRA S.R.O. 279(I)/2026 K-Electric residential notification effective 10 February 2026, plus the K-Electric official tariff structure page at ke.com.pk. Verified slab rates: 1-50 lifeline (Rs 3.95), 51-100 protected (Rs 7.74), 101-200 protected (Rs 13.01 with Rs 300 fixed), 301-400 non-protected (Rs 36.46 with Rs 400 fixed), 401-500 non-protected (Rs 38.95 with Rs 500 fixed), 601-700 (Rs 41.85), above 700 (Rs 47.20). Non-protected middle slabs (1-100, 101-200, 201-300, 501-600) where the source data did not surface explicit amounts were interpolated from LESCO baseline plus a 10 percent K-Electric premium. Confirm against ePay Karachi or your K-Electric bill for exact figures.

How do I pay my K-Electric bill online?

K-Electric bills can be paid through the KE Live mobile app, the K-Electric official website (ke.com.pk), online banking (all major Karachi banks), 1-Link ATM network, JazzCash, Easypaisa, and over-the-counter at partner banks including HBL, UBL, Bank Al Habib and Bank Alfalah. Enter your 13-digit K-Electric consumer number to fetch the current bill. Payment reflects on your account instantly and you receive an SMS confirmation.

How can I lower my K-Electric bill quickly?

Six practical levers specific to Karachi households: (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 3-5 days if you are close to the next slab boundary. (3) If your 6-month average is drifting toward 200 units, aggressively reduce for 2-3 months to drop into protected status. (4) Set AC thermostat to 26-27 C rather than 22-23 C, each degree colder adds 6-8 percent to AC running cost. (5) Time washing machine and geyser use to off-peak hours or opt for TOU tariff. (6) Solar with net billing is the structural fix for consistently high Karachi bills, especially given the roof-space-per-household is decent in DHA, Clifton, and Gulshan areas.

Does K-Electric have the same taxes as other DISCOs?

Yes for federal taxes, no for provincial. K-Electric bills carry the same federal charges as all Pakistani electricity bills: FC surcharge Rs 0.43 per unit, NJ surcharge Rs 0.10 per unit, GST 18 percent, TV fee Rs 35, Section 235 non-filer WHT 7.5 percent. Electricity Duty (1.5 percent) is a provincial levy so Sindh Electricity Duty applies to K-Electric consumers, same rate but administratively different from the Punjab Electricity Duty on LESCO consumers. FPA and QTR are utility-specific to K-Electric based on its own generation and purchased-power cost stack, so K-Electric FPA can differ meaningfully from LESCO FPA in the same month.

About the K-Electric Bill Calculator 2026-27 (Karachi Slab Warning + TOU)

Free K-Electric bill calculator for Karachi residential consumers, updated to the NEPRA S.R.O. 279(I)/2026 K-Electric residential tariff notification effective 10 February 2026. K-Electric is Pakistan's only privately-owned vertically integrated utility, serving 3.9 million customers across Karachi, Hub, Vinder, Bela and Uthal. Unlike the 10 WAPDA-connected DISCOs, K-Electric runs its own generation, transmission and distribution, which is why its residential tariffs run 5 to 10 percent higher than the LESCO reference on the upper slabs. Handles the three consumer categories: protected (six-month rolling average under 200 units, subsidised rates with modest Rs 300 fixed charge on the upper protected slab), non-protected (six-month average over 200 units, progressive rate slabs from Rs 18.13 per unit climbing to Rs 47.20 per unit above 700 units, plus fixed monthly charges from Rs 100 to Rs 650), and TOU (Time of Use, voluntary opt-in with dual meter, cheaper off-peak rate Rs 24.15 versus peak Rs 42.85 during 6 PM to 10 PM). Killer feature is a live slab-crossing warning that fires when your current month usage is within 10 units of the next slab boundary. The full breakdown includes slab-by-slab base energy charge, monthly fixed charge, FPA (Fuel Price Adjustment, user-adjustable), 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, GST 18 percent, TV fee Rs 35, and Section 235 non-filer WHT 7.5 percent on bills over Rs 25,000.
