Ever stared at your IESCO electricity bill and wondered, “Where did all these extra charges come from?” You’re not alone. Most of us just look at the total, sigh, and move on — without really knowing what we’re actually paying for.

But here’s the thing: your electricity bill isn’t just a random number. It’s a combination of unit consumption, government taxes, fuel adjustments, TV license fees, and more. Understanding these charges can help you take control of your energy usage — and even save money each month.

This is where NEPRA (short for National Electric Power Regulatory Authority) plays a big role. They decide how much electricity should cost, how the tariff structure works, and make sure companies like IESCO (Islamabad Electric Supply Company) follow fair billing practices for homes and businesses across Pakistan.

In this guide, we’ll explain each part of your IESCO bill in simple, clear language. No jargon. No confusion. Just a friendly walk through your bill — so next time it arrives, you’ll know exactly what you’re paying for, and why.

Let’s break it down together.

Understanding IESCO Bill Format

If you’ve ever taken a closer look at your IESCO electricity bill, you’ll notice it’s packed with details—some useful, others a bit confusing at first. But once you know where to look, it’s surprisingly easy to understand.

Let’s break it down, section by section:

Consumer Information

At the top of your bill, you’ll see your Consumer ID, name, and address. This ID is your unique number in IESCO’s system—kind of like your electricity account number. You’ll need this when checking your bill online, filing complaints, or making payments.

Reference Number

Just below the consumer info, you’ll find the reference number. This number is tied to your billing record and region. It’s also essential for viewing or downloading your bill online. Think of it as your bill’s tracking ID.

Billing Cycle & Due Date

Your bill includes a billing cycle—usually a one-month period during which your electricity usage is recorded. Alongside that, you’ll see your issue date and due date, so you know exactly when to pay to avoid late charges.

Meter Reading Details

This part shows your current and previous meter readings, usually in kWh (kilowatt-hours). The difference between the two tells how many units of electricity you’ve used this month.

If you have a smart meter, you might also notice readings for peak and off-peak hours, which helps calculate different rates depending on the time of day you use power.

A. Energy Charges – What You’re Really Paying For

Let’s start with the core of your IESCO electricity bill: the energy charges. This is the main portion of your bill—the actual cost of the electricity you’ve used.

But here’s the catch: it’s not a flat rate. Your cost per unit (kWh) depends on how much electricity you use and when you use it.

Per Unit Cost & Consumption Slabs

IESCO (like other electricity providers in Pakistan) uses a slab system. That means the more units you consume, the more expensive each unit becomes. Here’s a simplified example:

  • 0–100 units: Lower rate (for lifeline or low-usage consumers)

  • 101–300 units: Moderate rate

  • 301–700+ units: Higher per unit rate

So, if you’re using more power, you’re not just consuming more units—you’re also moving into higher tariff slabs, increasing the total bill.

⏰ Peak and Off-Peak Hour Rates (TOU Meters)

If you have a TOU (Time of Use) meter, your bill gets even more interesting. These meters track when you use electricity—dividing it into:

  • Peak hours: Usually 6 PM to 10 PM (when demand is highest and rates are more expensive)

  • Off-peak hours: The rest of the day and night (with lower rates)

Using heavy appliances like ACs, washing machines, or electric water heaters during off-peak hours can help cut your energy charges significantly.

Understanding this section of the bill helps you plan smarter—maybe shift some of your energy-heavy tasks to cheaper hours, or stay within a lower slab to save more every month.

⚙️ B. Fuel Price Adjustment (FPA) – The Monthly Surprise

You might have noticed an extra charge on your IESCO bill called FPA or Fuel Price Adjustment—and wondered what it means or why it keeps changing.

Let’s break it down in simple terms.

What is FPA?

The Fuel Price Adjustment is a cost that reflects the change in fuel prices used to generate electricity. Since a large portion of Pakistan’s power supply comes from thermal and oil-based power plants, the cost of fuel directly affects how much it costs to produce electricity.

When fuel prices go up, the difference is passed on to the consumer as an FPA charge in the electricity bill. If fuel prices drop, you might even get a little relief in the form of a negative adjustment—but let’s be real, that’s rare.

Why Does FPA Change Every Month?

FPA isn’t a fixed fee. It’s recalculated each month based on:

  • International oil prices

  • Fuel consumption reports

  • Power generation mix

  • Exchange rate fluctuations

NEPRA (National Electric Power Regulatory Authority) reviews these factors and issues monthly notifications. Then, IESCO adjusts your bill accordingly in the following billing cycle.

So if your bill suddenly feels higher than last month, it’s often due to a fuel price spike reflected in the FPA.

Pro Tip:
FPA is charged on a per-unit basis, meaning the more electricity you use, the more FPA you’ll be paying.

Understanding FPA helps you see the bigger picture of your bill—because it’s not just about what you consume, but also about what it costs to generate that power in real-time.

C. Electricity Duty – The Government’s Cut

Another line item you’ll find on your IESCO electricity bill is Electricity Duty—but what exactly is it, and who’s charging you for it?

Let’s clear it up.

️ What is Electricity Duty?

Electricity Duty is a type of tax added to your bill by the provincial government, not by IESCO itself. It’s calculated as a percentage of your total electricity charges, and the rate can vary slightly depending on the type of consumer (domestic, commercial, industrial) and the province you live in.

In most cases across Pakistan, the electricity duty is around 1.5% to 1.8% of your total energy charges.

⚖️ Who Levies This Duty?

This surcharge is imposed by the provincial energy departments—meaning if you’re living in Punjab, Sindh, or another province, the respective provincial government applies this tax under local laws.

IESCO simply collects it on their behalf and includes it in your monthly bill as a line item—so you don’t have to pay it separately.

Quick Note:
This duty is non-adjustable, meaning it doesn’t fluctuate like the Fuel Price Adjustment (FPA)—but it does add up over time, especially for high-usage consumers.

So while it may seem like a small percentage, Electricity Duty is yet another factor that increases your overall bill—and it’s important to know that it comes straight from the government’s side, not the power company.

Next up: GST – General Sales Tax — the biggest tax in your electricity bill.

D. General Sales Tax (GST) – The Heaviest Hit on Your Bill

One of the biggest charges on your IESCO electricity bill—after energy usage—is the General Sales Tax (GST). It’s not hidden, but it often goes unnoticed because most people don’t fully understand how it’s calculated.

Let’s fix that.

What is GST in Your IESCO Bill?

GST (General Sales Tax) is a federal tax applied to various goods and services across Pakistan—including electricity. In your IESCO bill, it’s listed as a separate item and is calculated as a percentage of your total bill (excluding some government charges).

Currently, GST is charged at a standard rate of 17%, but it can vary based on your consumer type:

  • Domestic consumers may have exemptions or reduced rates under specific usage thresholds.

  • Commercial and industrial users are usually charged the full 17%.

How is GST Calculated?

Here’s a simplified version of how it works:

  1. First, your energy charges, FPA, and other applicable fees (excluding already-taxed items) are added.

  2. Then, 17% of that subtotal is calculated and added as GST.

Example:
If your bill (before GST) is PKR 5,000, then:
17% of 5,000 = PKR 850
So your total becomes PKR 5,850.

Important Tip:
GST increases with your total usage, so keeping your unit consumption lower can indirectly reduce your tax burden too.

In short, GST is a federal tax that forms a significant portion of your final bill—and understanding how it’s applied helps you see exactly where your money’s going.

E. TV License Fee – Paying for PTV, Like It or Not

Ever noticed a small charge on your IESCO electricity bill labeled something like “TV Fee” or “PTV License Fee”? You’re not imagining things—it’s a real charge, and yes, you’re paying it even if you don’t own a television.

Let’s clear up the confusion.

What is the TV License Fee?

The TV License Fee is a fixed amount added to every household’s electricity bill across Pakistan to fund Pakistan Television Corporation (PTV)—the country’s national broadcaster.

Right now, it’s usually Rs. 35 for domestic consumers and Rs. 60 for commercial ones, though this may vary slightly over time.

But I Don’t Watch PTV! Why Am I Paying?

That’s a question many people ask. The short answer is: it’s mandatory.

The TV fee isn’t based on whether or not you watch TV—it’s a universal charge applied through your electricity bill under government policy. This ensures steady funding for PTV operations, regardless of viewer count.

Even if you:

  • Don’t own a TV

  • Only use Netflix or YouTube

  • Watch other channels via cable

…you’ll still see this PTV fee on your IESCO bill. It’s one of those hidden charges that feels unfair—but it’s legally enforced.

Did You Know?
This fee is collected by all power companies in Pakistan—not just IESCO—as part of a federal-level initiative.

So, while it may seem small, the TV License Fee is just another item quietly increasing your monthly bill—regardless of your viewing habits.

F. Meter Rent – A Small Fee for Old Meters

If you still have an old analog electricity meter installed in your home or shop, there’s a good chance you’ll see a small amount labeled “Meter Rent” on your IESCO bill.

Let’s explain what it is—and why it might be on your bill.

What is Meter Rent?

Meter Rent is a fixed monthly charge applied to consumers who are still using non-digital (analog) meters provided by IESCO. The fee is meant to cover the cost of maintaining and owning the physical meter.

In most cases, the charge is minimal—usually around Rs. 15 to Rs. 50 per month, depending on your meter type and connection category.

Do All Consumers Pay Meter Rent?

No. If you have a smart meter or a digital TOU (Time of Use) meter, you likely won’t see this charge on your bill. Newer meters are either owned by the consumer or fall under different maintenance policies that don’t require monthly rent.

Important Tip:
If you’re still being charged Meter Rent and your meter has been upgraded, it’s a good idea to contact IESCO to verify your billing status.

So, while Meter Rent may seem like a small amount, it’s one more item adding up on your electricity bill—especially for long-time users with older equipment.

⏰ G. Late Payment Surcharge – The Cost of Missing the Due Date

If you’ve ever paid your IESCO electricity bill a few days late, you’ve probably noticed an extra amount added the next month. That’s the Late Payment Surcharge, and while it may not seem huge at first, it’s something you definitely want to avoid.

bill-components-explained

What Is the Late Payment Surcharge?

The Late Payment Surcharge is a penalty fee added to your bill if you fail to pay the total amount due before the due date printed on your bill.

It’s IESCO’s way of encouraging timely payments—and unfortunately, it’s non-negotiable once it’s applied.

How Much Is the Penalty?

The surcharge is typically calculated as a flat percentage of the unpaid amount. Currently, IESCO charges around 10% of the outstanding bill amount as a late payment fee. So, for example:

  • If your unpaid bill is PKR 6,000,

  • You may be charged an additional PKR 600 as a late surcharge.

This fee will be added to your next month’s bill, increasing the total due—and making it harder to catch up if you delay again.

Tip to Avoid Late Fees:

  • Always check your billing cycle and due date carefully.

  • If you’re often busy, consider setting a monthly reminder or using IESCO’s online payment portal to stay on track.

Paying your bill on time not only avoids penalties but also keeps your electricity connection safe from potential disconnection due to non-payment.

Now that you know what each component of your IESCO bill means, you’re in a much better position to manage your usage—and your budget.

Consumer Tariff Categories – Why Your Bill Isn’t Like Everyone Else’s

Not all electricity bills are created equal—and that’s because IESCO charges different rates depending on what type of consumer you are. These categories are set by NEPRA (National Electric Power Regulatory Authority) and play a huge role in how much you pay each month.

Let’s explore the four main NEPRA tariff categories and how they affect your billing rates and taxes.

1. Lifeline Consumers

This category is for low-income households who consume up to 100 units per month. It’s part of the government’s effort to subsidize electricity for the most vulnerable segments of society.

  • Lower per-unit rates

  • Reduced taxes

  • No FPA or minimal FPA applied

If your monthly usage stays under the lifeline threshold, you’ll benefit from significantly cheaper bills.

2. Domestic Consumers

This is the most common category—for homes and apartments using electricity for everyday needs like lighting, fans, appliances, and more.

Billing here is slab-based, meaning:

  • The more you use, the more you pay per unit

  • Different tax slabs and FPA amounts apply depending on usage (e.g., 0–100, 101–300, 301–700+ units)

This is where energy-saving habits can make a big difference in your final bill.

3. Commercial Consumers

If you’re running a shop, office, or small business, your connection likely falls under the commercial category.

  • Higher per-unit rates compared to domestic

  • Full GST (17%) and FPA applied

  • Often charged additional commercial duties or meter rent

Even moderate usage can lead to significantly higher bills, so commercial users need to manage consumption smartly.

4. Industrial Consumers

Factories, mills, and large-scale businesses fall into the industrial tariff category, which has a separate set of NEPRA rates and additional conditions like:

  • Time of Use (TOU) billing

  • Demand-based charges

  • Special industrial surcharges

Industrial billing is complex and usually monitored through dedicated metering systems.

Why It Matters

Understanding your tariff category helps you:

  • Know why your bill is high or low

  • Find out if you’re eligible for subsidies or special rates

  • Take smarter steps to reduce your electricity costs

If you think your connection is billed under the wrong category, you can contact IESCO to verify or apply for a tariff reclassification.

Next, let’s look at how your total bill is calculated — and how you can estimate it before it even arrives.

5. How IESCO Calculates Your Final Bill – The Full Picture

Ever wonder how your total electricity bill is calculated?

IESCO doesn’t just multiply your units by a fixed price. Instead, it follows a structured formula that adds together your electricity usage, fuel charges, taxes, and fixed fees.

Let’s walk through the IESCO bill calculation method, so you can estimate your monthly bill more confidently.

Basic Formula for IESCO Bill Calculation:

Total Bill = (Energy Charges + FPA) + Taxes + Fixed Charges

Here’s a breakdown of what each part means:

  • Energy Charges: Units consumed × per-unit rate (based on slab)

  • FPA (Fuel Price Adjustment): Units × FPA rate for the month

  • GST (Sales Tax): 17% of subtotal (excluding fixed charges)

  • Electricity Duty: Around 1.5% of energy charges

  • TV License Fee: Fixed (Rs. 35 for domestic, Rs. 60 for commercial)

  • Meter Rent: If applicable

  • Late Payment Surcharge: Only if paid after the due date

Example: Monthly Bill Estimate

Let’s say a domestic consumer uses 350 units this month.

Component Calculation Amount (PKR)
Energy Charges First 100 units @ Rs. 5 = 500
Next 200 units @ Rs. 10 = 2,000
Remaining 50 units @ Rs. 15 = 750 3,250
FPA 350 units × Rs. 1.75 (FPA rate) 612.50
Electricity Duty (1.5%) 1.5% of 3,250 48.75
GST (17%) 17% of (Energy + FPA) = 17% of 3,862.50 656.62
TV License Fee Fixed 35
Total Estimated Bill Sum of all above 4,602.87

(Note: Rates are examples only and may vary by NEPRA updates.)

Why This Matters

Knowing this formula helps you:

  • Avoid surprises when your bill arrives

  • Estimate future bills based on appliance usage

  • Understand which components are fixed and which can be controlled

Whether you’re trying to save electricity or just curious about that extra charge, understanding how IESCO calculates your total is key to managing your energy costs smartly.

6. Smart Tips to Reduce Your IESCO Electricity Bill

Tired of high electricity bills? You’re not alone.

With rising energy costs in Pakistan, it’s more important than ever to use electricity wisely. These simple tips can help you reduce your IESCO bill, especially if you’re on a tight monthly budget.

⏰ 1. Use Appliances During Off-Peak Hours

If you have a Time of Use (TOU) meter, this tip alone can save you thousands.

  • Off-peak hours (usually late night or early morning) have cheaper unit rates.

  • Avoid using heavy appliances like air conditioners, washing machines, and irons during peak hours (usually 6 PM to 10 PM).

Pro tip: Shift laundry, water pumping, and dishwashing to off-peak hours.

2. Understand Your Slab Benefits

IESCO uses a slab-based billing system—the more units you use, the higher the per-unit rate becomes.

  • Try to stay within lower consumption slabs (e.g., under 200 or 300 units) where subsidized rates apply.

  • Monitor your usage weekly to avoid crossing the next slab.

Example: If you’re at 395 units, using just 5 more can push your entire bill into a more expensive slab.

3. Monitor Your Usage with a Smart Meter

If you have a smart meter, take advantage of its real-time tracking features.

  • Use mobile apps or IESCO’s online tools to track daily and weekly usage.

  • Identify which appliances consume the most electricity.

  • Adjust usage patterns based on insights.

Bonus Tips:

  • Use energy-efficient LED lights and inverter appliances.

  • Turn off devices completely—don’t just leave them on standby.

  • Get your home wiring checked to avoid energy leakage.

Small Changes, Big Savings

Saving on your IESCO bill doesn’t require drastic changes—just smart choices.

With a mix of awareness, off-peak usage, and slab management, you can easily cut 10–20% off your monthly bill.

Electricity Saving Checklist

IESCO Bill FAQs – Your Questions Answered!

What is FPA in IESCO bill?

Fuel Price Adjustment (FPA) is a variable charge that reflects changes in fuel prices used to generate electricity. NEPRA adjusts this monthly based on fuel cost fluctuations. It’s added to your bill to compensate for the difference between estimated and actual fuel prices.

Why am I charged GST on electricity?

GST (General Sales Tax) is a government-imposed tax added to your electricity bill based on your energy consumption. It’s calculated on the total energy charges and appears as a percentage. This tax helps fund national services and infrastructure.

How can I estimate my next electricity bill?

To estimate your next bill, note your current unit usage, apply the applicable per-unit rates based on your consumer category, and add common charges like FPA, GST, and TV fee. You can also use a smart meter or online calculators to get an estimate.

What are off-peak and peak hours in Islamabad?

If you have a Time of Use (TOU) meter, peak hours (typically 6 PM to 10 PM) are charged at a higher rate. Off-peak hours (rest of the day and night) have lower per-unit rates. Using heavy appliances during off-peak hours helps reduce your bill.

What happens if I don’t pay my bill on time?

Missing your due date adds a Late Payment Surcharge (usually 10% of the current bill amount). Delays beyond a few weeks can lead to disconnection notices. Always try to pay before the due date to avoid extra charges.
