✅ What is Protected Consumer Status for IESCO?

If your monthly consumption is ≤200 units, you qualify as a protected consumer and pay subsidised rates (lifeline rates). If you exceed 200 units in any month, you become non‑protected and your entire consumption is billed at higher rates.

Example: 190 units → Protected → Bill ~Rs 3,115. 210 units → Non‑protected → Bill ~Rs 8,674. Difference of Rs 5,559 for just 20 extra units!

📌 Real IESCO Bill Calculation Examples (including FCA)

Example 1 – Protected (180 units):
Energy: (50×3.95)+(50×7.74)+(80×13.01) = Rs 1,625
Fixed: Rs 300 | Subtotal: 1,925 | GST: Rs 347 | Base bill: Rs 2,272
Add FCA (Rs 3.2/unit ×180 = Rs 576) → Final ≈ Rs 2,848

Example 2 – Non-Protected (350 units):
Energy: (50×3.95)+(50×7.74)+(100×13.01)+(150×33.10) = Rs 7,018.5
Fixed: Rs 400 | Subtotal: 7,418 | GST: Rs 1,335 | Base bill: Rs 8,753
Add FCA (Rs 3.2/unit ×350 = Rs 1,120) → Final ≈ Rs 9,873

💡 How to Reduce Your IESCO Bill

• Stay under 200 units – Protected consumer rates save you thousands.
• Monitor your meter every 5 days – If you reach 160 units by the 25th, reduce usage drastically.
• Set AC to 26°C – Each degree below 26 adds 8% to your bill.
• Install LED bulbs – Replace 10 bulbs → save 30‑50 units monthly.
• Use fans instead of ACs when possible – Fans consume only 70W, ACs 1500W.

How this IESCO 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 IESCO bill can differ

• Fuel Cost Adjustment (FCA) – typically around Rs 2.8–4.2 per unit for IESCO, 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.

IESCO's territory includes both federal-capital housing sectors and rural Potohar areas, so consumption patterns – and therefore bills – vary widely across the region.

What you need before using the IESCO calculator

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

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