How IESCO Calculates Your Electricity Bill

Explanation of the Slab‑Rate (Tariff Slab) System

IESCO applies a tiered unit slab system for residential (A‑1 tariff), where the unit rate increases the more you consume. Lifeline and protected consumers enjoy lower per‑unit rates for low usage, while non‑protected users are charged higher rates as consumption increases

For example:

  • Lifeline consumers (up to 50 units): ~Rs 3.95/kWh

  • Protected (51–100 units): ~Rs 7.74/kWh

  • Protected (101–200 units): ~Rs 14.16/kWh

Once usage exceeds these slabs and protection limits, non‑protected rates begin:

  • 1–100 units: ~Rs 23.59/kWh

  • 101–200: ~Rs 30.07/kWh

  • 201–300: ~Rs 34.26/kWh, and so on, scaling up to over Rs 48 per kWh for usage above 700 units

Current Tariff Per Unit Breakdown

Here is a simplified snapshot of IESCO’s updated residential tariff slabs in Rs/kWh:

Slab Rate (Rs/kWh)
Up to 50 units (Lifeline) ~3.95
51–100 units (Protected) ~7.74
101–200 units (Protected) ~14.16
1–100 units (Non‑Protected) ~23.59
101–200 units ~30.07
201–300 units ~34.26
301–400 units ~39.15
401–500 units ~41.36
501–600 units ~42.78
601–700 units ~43.92
Above 700 units ~48.84
*Actual rates may slightly differ due to periodic adjustments by NEPRA

⚙️ Key Components That Determine Your Final Bill

  1. Energy Charges
    Based on total electricity units consumed (kWh), charged according to your applicable slab.

  2. Fixed Charges
    A flat monthly charge applies regardless of usage—Rs. 75/month for single-phase and Rs. 150/month for three-phase connections. Some slabs include fixed charges per kW of sanctioned load as well.

  3. FPA (Fuel Price Adjustment)
    A variable surcharge applied monthly to account for fluctuations in fuel costs, passed through by NEPRA.

  4. Electricity Duty & GST
    Government levies added to your bill, calculated on consumption and applicable to your region.

  5. TV License Fee
    A nominal fee applied monthly as per regulations.

  6. Late Payment Surcharge
    Additional charges if your payment crosses the due date.

IESCO Bill Calculation Formula (Manual Method)

If you’re curious how your electricity bill is calculated behind the scenes — or want to double-check your bill without using a tool — you can use the manual IESCO bill calculation formula. This helps you understand how each unit adds up and how taxes and surcharges affect your total.

Basic Formula

Total Bill = (Units Consumed × Per Unit Rate) + Fixed Charges + FPA + GST + Electricity Duty + TV Fee

Note: The per-unit rate depends on your consumption slab and protection status (protected/non-protected).

Sample Case – Domestic User

Let’s walk through a real example:

  • Units Consumed: 350

  • Tariff Type: Domestic – Non-Protected

  • Assumed Slab Breakdown (example):

    • First 100 units @ Rs. 23.59 = Rs. 2,359

    • Next 100 units @ Rs. 30.07 = Rs. 3,007

    • Next 100 units @ Rs. 34.26 = Rs. 3,426

    • Remaining 50 units @ Rs. 39.15 = Rs. 1,957.5

Subtotal (Energy Charges):
2,359 + 3,007 + 3,426 + 1,957.5 = Rs. 10,749.50

➕ Other Charges (Approximate)

Charge Type Value (Rs.)
Fixed Charges 75 (for single-phase)
FPA ~500 (variable)
Electricity Duty ~2.5% of energy cost = ~268.7
GST ~17% of energy cost = ~1,827.4
TV License Fee 35

Total Estimated Bill


= Energy Charges + Fixed + FPA + Duty + GST + TV Fee
= 10,749.50 + 75 + 500 + 268.7 + 1,827.4 + 35
= Rs. 13,455.60

✅ Final Estimated Bill:

Rs. 13,456 (rounded off)

This manual method helps you verify your monthly IESCO bill or estimate future charges based on your usage. While it gives you a close approximation, for more accurate results—especially when tariffs are updated—it’s best to use the IESCO Bill Calculator.
