K-Electric Peak Hours Savings Calculator

⏰ Peak hours: 6:30 PM – 10:30 PM (April–October) | 6:00 PM – 10:00 PM (November–March)
Running heavy appliances during off‑peak hours can significantly reduce your TOU (Time of Use) bill.

Peak electricity is charged at ~Rs 42/unit (non‑protected), off‑peak at ~Rs 30/unit. Shift laundry, ironing, and water pumps to off‑peak hours.

⏰ K-Electric Peak Hours Karachi 2026 – Complete TOU Tariff Guide

If your sanctioned load is 5kW or above (most 3‑phase connections), you are billed under Time of Use (TOU) regime. Peak hours have higher rates, while off‑peak hours are cheaper.

💡 Saving tip: Run washing machines, dishwashers, water pumps, and electric geysers during off‑peak hours (after 10:30 PM). Avoid using ACs, ovens, and heavy machinery during peak hours.

📌 Real K-Electric Bill Calculation Examples

Example 1 – Protected Consumer (180 units):
Energy: (50×3.95)+(50×7.74)+(80×13.01) = Rs 1,625
Fixed: Rs 300 | GST: Rs 347 | Total: Rs 2,272

Example 2 – Non-Protected with peak/off‑peak (350 units, 40% during peak):
Peak units: 140 × Rs 42 = Rs 5,880
Off‑peak: 210 × Rs 30 = Rs 6,300
Fixed: Rs 400 | GST: Rs 2,264 | Total: Rs 14,844
Shifting to 20% peak could reduce bill to ~Rs 12,500.

How this K-Electric bill estimate is calculated

Tariff data last reviewed: 23 August 2026. Slab rates used by this page are stored in a single file (assets/tariffs.js) and applied to every calculator on this site.

1. Your monthly units are split across the NEPRA domestic slabs and each part is charged at its own rate.
2. A fixed (minimum) monthly charge is added according to your consumption band.
3. General Sales Tax at 18% is applied to the energy plus fixed charge.

The result is a base estimate. It deliberately excludes items that change every month and are printed on your own bill.

Why your actual K-Electric bill can differ

• Fuel Cost Adjustment (FCA) – typically around Rs 2.5–4.5 per unit for K-Electric, changing monthly. Multiply your units by the FCA on your bill and add it.
• Quarterly tariff adjustments – recovered over several months and shown as a separate line.
• Billing period length – a cycle of 33 days records more units than one of 28 days.
• Arrears and late-payment surcharge – unpaid amounts from earlier months.
• Fixed line items – meter rent, TV fee and, where applicable, income tax or municipal charges.
• Time-of-Use meters – if your bill lists peak and off-peak units separately, a single-rate slab estimate will not match it.

K-Electric is a vertically integrated private utility rather than a WAPDA distribution company, so its tariff schedule and adjustment mechanism are notified separately even though domestic slab structure is closely aligned.

What you need before using the K-Electric calculator

Only one number: units consumed this month. You can find it in two ways.

• Read the Units Consumed field on your printed K-Electric bill.
• Or subtract the previous meter reading from the current reading – both are printed on the same bill.
