⚡ GEPCO Online Bill Calculator 2026

Electricity bills in Pakistan are rarely simple. They combine slab-based tariffs, seasonal peak hours, fuel price adjustments, fixed charges, and multiple government levies. For GEPCO consumers in Gujranwala and surrounding regions, understanding these components is often more difficult than estimating actual consumption. This page exists for one practical purpose: to help you estimate your monthly GEPCO bill with clarity, using current tariff logic for 2026.

The calculator on this page does not pull live billing data from GEPCO. Instead, it applies official NEPRA-approved tariff structures, common surcharges, and standard fixed charges to your unit input. This approach allows you to predict your bill before it arrives, evaluate different usage scenarios, and understand how changes in consumption or peak-hour usage affect your total payment.

You can use the tool in two main ways. You can enter your total monthly units directly if you already know your meter reading difference, or you can estimate your usage through the appliance estimator and transfer those units into the calculator. Both methods lead to the same bill breakdown, including base tariff cost, surcharges, taxes, and late payment penalties when selected.

How the calculator works in simple terms

The calculator follows the same basic logic that appears on a real GEPCO bill. First, it determines your applicable tariff based on your consumer category, protected or unprotected status, and total units. Then it applies fixed charges such as meter rent. After that, it adds variable surcharges like Fuel Price Adjustment and financing cost. Finally, it calculates government taxes including General Sales Tax and Electricity Duty.

If you select a normal meter, the tool applies a single blended rate across your total units. If you select a Time of Use meter, the tool separates peak and off-peak consumption and applies different effective rates to each. This mirrors how TOU billing is structured in practice, where electricity during peak hours costs more than during off-peak periods.

Late payment surcharge is optional in the tool because not every user wants to include it. When enabled, the calculator adds ten percent to your subtotal, which reflects the standard penalty applied when a bill is paid after the due date.

Understanding GEPCO consumer categories

GEPCO bills are not calculated using one universal rate. The first major distinction is consumer type. Residential consumers fall under category A-1, commercial consumers under A-2, and industrial users under category B. Agricultural consumers are treated separately with subsidized rates.

Residential tariffs are further divided into protected and unprotected status. Protected consumers generally pay lower rates because they receive partial government support. Unprotected consumers pay higher rates across most slabs. Whether you are protected or not depends on your official classification in GEPCO records, not on your personal preference.

Commercial and industrial consumers do not usually receive protected status in the same way as residential users. Their rates are primarily determined by demand, connection type, and sanctioned load rather than household subsidy policies.

How slab-based billing actually works

GEPCO applies increasing rates as consumption rises. This means your bill is not calculated at a single flat rate. Instead, different portions of your usage fall into different slabs, each with its own price per unit.

For example, a low-usage household consuming fewer than 100 units may fall into a lower-cost bracket. A household consuming 300 or 400 units will pay much higher rates for the additional units beyond the lower slabs. This progressive structure is designed to discourage excessive electricity use.

Many consumers mistakenly assume that crossing a slab threshold increases the rate for all their units. That is incorrect. Only the units above the threshold are billed at the higher rate. The calculator follows this same principle when estimating your bill.

Peak hours and Time of Use metering

Peak hours are periods when electricity demand is highest across Pakistan’s grid. During these times, generation costs rise and supply pressure increases. To manage this, utilities encourage consumers to shift usage to off-peak periods by charging higher rates for peak consumption.

In winter, peak hours typically run from 5 PM to 9 PM. In spring and autumn, they shift to 6 PM to 10 PM. In summer, when air conditioners and fans are heavily used, peak hours extend from 7 PM to 11 PM.

If you have a Time of Use meter, your bill separates units consumed during peak and off-peak hours. The calculator allows you to enter these separately so your estimate reflects this structure. If you have a normal meter, all units are treated as standard consumption without time differentiation.

Fuel Price Adjustment and monthly variations

One of the most confusing parts of any GEPCO bill is the Fuel Price Adjustment. This is not a fixed charge. It changes almost every month based on global fuel prices, power generation mix, and government policy.

When fuel costs rise, the FPA component on your bill increases. When costs fall, it may decrease. Because of this variability, any online calculator can only estimate FPA using recent averages or standard assumptions. Your actual bill may still differ slightly from the estimate.

The tool on this page applies a realistic per-unit FPA assumption based on recent trends. This provides a useful forecast but should not be treated as an official final amount.

Fixed charges, meter rent, and financing cost

Even if you use very little electricity, you will still pay certain fixed charges. Meter rent is the most common example. This covers the maintenance of your electricity meter and related infrastructure.

In addition, many bills include a financing cost surcharge. This reflects government borrowing related to the energy sector. It is calculated as a percentage of your consumption-related charges rather than as a flat fee.

These components mean that your bill will never be zero, even if your usage is minimal. The calculator accounts for this by always including fixed charges based on your selected consumer type.

General Sales Tax and Electricity Duty

Two mandatory government taxes appear on almost every GEPCO bill. General Sales Tax is typically 17 percent of your electricity-related charges. Electricity Duty is usually 1.5 percent and applies primarily to the consumption portion of your bill.

Both taxes are calculated after adding certain surcharges, which is why the final tax amount can be higher than expected. The calculator follows this same sequence so your estimate aligns closely with real billing logic.

TV fee and additional levies

Residential consumers are often charged a TV license fee, even if they do not own a television. Commercial users may face a higher TV fee or additional service-related levies depending on their connection type.

Industrial consumers usually do not pay the standard residential TV fee but may face other sector-specific charges instead. The calculator applies typical TV fee amounts for residential and commercial users while excluding it where it does not normally apply.

Using the appliance estimator effectively

Many users do not know their monthly electricity units in advance. The appliance estimator helps bridge this gap by converting daily usage hours into estimated kWh consumption.

Each appliance in the estimator is assigned a realistic power rating based on typical models in Pakistan. For example, a 1.5-ton air conditioner is treated as roughly 1.5 kW, while LED lighting and fans consume far less power.

You enter how many hours per day you use each appliance. The tool then calculates total daily usage and converts it into monthly units. You can transfer these units directly into the main calculator with one click.

This method is not perfectly precise. Actual consumption depends on appliance efficiency, brand, maintenance, voltage stability, and real-world usage patterns. However, it provides a practical and reliable starting point for budgeting.

How to read your bill breakdown in the tool

After calculation, the results panel shows a detailed list of components. The base tariff rate reflects the applicable slab for your consumption. Electricity cost represents your total usage multiplied by that rate or separate peak and off-peak rates for TOU meters.

Meter rent appears as a fixed amount based on your consumer category. Fuel Price Adjustment and financing surcharge appear as per-unit or percentage-based additions. Taxes are displayed separately so you can clearly see how much you are paying to the government versus the utility.

The total bill amount at the bottom is the sum of all these elements plus any late payment surcharge if selected.

Common mistakes users make

Many consumers underestimate their units because they look only at appliance hours without considering seasonal variation. Air conditioners in summer, for instance, can double or triple monthly consumption compared to winter.

Another frequent mistake is ignoring peak hours. Even a moderate amount of peak usage can significantly increase your bill if you have a TOU meter.

Some users also forget that previous unpaid amounts roll into the next bill automatically. If you miss a payment, arrears appear on your current bill and affect your total payable amount.

What this calculator cannot do

This tool does not retrieve your actual GEPCO bill from the PITC database or Customer Information System. It does not replace the official online bill portal, bank receipt, or ERP pay slip.

It cannot display your billing history, generate a duplicate bill, or confirm whether your payment has been received. Those functions belong to GEPCO’s official systems and the government’s Power Smart app.

If you need an old bill beyond what is visible on your current statement, you must contact GEPCO directly at your regional office or customer service center.

Power Smart app and how it relates to this page

The government of Pakistan has launched the Power Smart app to centralize many electricity services. Through this app, users can check bills, submit self meter readings, register complaints, request duplicate bills, and track payments.

You can also apply for new connections, request installment plans, update CNIC details, or change the registered user name on a meter. The app supports multiple distribution companies including GEPCO, LESCO, FESCO, IESCO, MEPCO, PESCO, HESCO, SEPCO, QESCO, and others.

Power Smart is available on the Google Play Store for Android and allows users to select their preferred language, including English, Urdu, Punjabi, Sindhi, Saraiki, Pashto, and Balochi.

While the app provides official records, this calculator complements it by helping you forecast costs before you receive your bill.

How this page fits into your website structure

This tariff calculator page is intentionally focused on estimation, rates, slabs, and peak hours. It does not attempt to cover payment methods, complaints, new connections, or duplicate bills in depth. Those topics belong on separate pages.

Your home page should introduce GEPCO online bill checking. Your duplicate bill page should focus on billing history and arrears. Your payment page should explain EasyPaisa, JazzCash, bank payments, and transaction status. This page remains dedicated to tariffs and cost estimation.

When to trust the estimate

The estimate is most reliable when your unit input is accurate and your consumer status is correctly selected. It works best for typical residential and small commercial users.

Estimates are less precise for large industrial consumers, special tariff categories, or users with unusual surcharges. In such cases, your official GEPCO bill remains the final authority.

Why this tool is useful even if you pay online

Many people pay their bills through mobile wallets or online banking without fully understanding what they are paying for. This calculator gives you visibility into every component of your bill before payment.

You can test scenarios such as reducing peak usage, switching to off-peak habits, or lowering air conditioner hours. Over time, this can meaningfully reduce your electricity costs.

Practical tips for lower bills

Shift heavy appliance use away from peak hours whenever possible. Use energy-efficient inverter ACs and LED lighting. Keep your refrigerator well maintained so it runs efficiently.

Regularly clean air conditioner filters and avoid running appliances unnecessarily. Even small changes can reduce monthly consumption by 10 to 20 percent.
