TESCO Bill Calculator: Calculate TESCO Electricity Bill Online, Units, Rates & Charges 2026
A TESCO Bill Calculator helps electricity consumers estimate their monthly electricity bill from the number of units consumed. For customers served by Tribal Areas Electricity Supply Company (TESCO), the final payable amount is not based on energy units alone. Electricity duty, GST, fuel-related adjustments, quarterly adjustments, fixed charges and other applicable government charges can also affect the bill.
TESCO supplies electricity across former FATA areas, where billing follows the applicable national electricity tariff framework. This guide explains how to calculate your TESCO bill, understand the tariff slabs, read your bill and estimate the amount payable for different levels of consumption.

How to Use This Calculator
- Enter your units consumed. Use the number shown on your meter this month, or the units figure printed on a recent TESCO bill.
- Select your consumer category. Choose Protected if your household has consistently used 200 units or fewer over the past six months, otherwise choose Non-Protected.
- Add FPA and quarterly adjustment if known. These figures appear as separate line items on your existing bill and change periodically; leave at zero for a base estimate.
- Confirm your tax filer status. Non-filers are charged an additional withholding tax under income tax rules, which this tool adds automatically when selected.
- Press Calculate. The tool works out your energy charge using the slab your total units fall into, then layers on duty, tax and surcharges the same way TESCO does.
- Fine-tune with Advanced settings. If NEPRA has issued a new tariff notification, open the Advanced panel and update the per-unit rates so future estimates stay accurate.
Understanding Your TESCO Bill
Protected vs Non-Protected
Protected consumers use less electricity on average and are billed at subsidized lifeline and protected rates. Once average consumption regularly exceeds 200 units, a connection is treated as Non-Protected and billed at standard slab rates.
Fuel Price Adjustment
FPA reflects the actual cost of fuel used to generate electricity nationally. It is reviewed monthly by the regulator and can raise or lower your bill compared to the base tariff.
Quarterly Tariff Adjustment
This surcharge is reviewed every three months and applied to higher-consumption Non-Protected connections to bridge the gap between actual distribution cost and the notified tariff.
Why Crossing a Slab Matters
TESCO bills the entire month’s units at the rate of the slab you reach, not just the extra units. Staying just under a threshold can meaningfully lower your total bill.

TESCO Electricity Bill Estimate by Units
The table below gives a quick way to understand how electricity consumption affects the energy component of a residential bill. Actual payable bills can differ because applicable charges and tariff categories vary.
| Monthly Units | Applicable Tariff Category | Bill Calculation |
|---|---|---|
| 50 units | Lifeline/protected category where applicable | Units × applicable tariff |
| 100 units | Protected category where applicable | Units × applicable tariff |
| 200 units | Residential slab | Units × applicable slab/rate |
| 300 units | Residential slab | Units × applicable slab/rate |
| 400 units | Residential slab | Units × applicable slab/rate |
| 500 units | Residential slab | Units × applicable slab/rate |
| 700 units | Residential slab | Units × applicable slab/rate |
| 1,000+ units | Higher residential category | Units × applicable tariff |
Because Pakistan's electricity tariff structure is periodically revised through government and NEPRA notifications, consumers should always compare the applicable rate on their latest TESCO bill with the current notified schedule.
How the TESCO Bill Calculator Works
Using a TESCO Bill Calculator is straightforward. First, determine the number of electricity units consumed during the billing period. One unit is equal to one kilowatt-hour (kWh).
For example, if your meter reading was 24,850 last month and it is now 25,150:
25,150 − 24,850 = 300 units
The calculator then applies the appropriate residential tariff and adds other applicable bill components.
A simplified calculation looks like this:
Electricity Cost = Units Consumed × Applicable Energy Rate
However, this is only the energy portion. Your actual TESCO bill may also contain fixed charges, GST, electricity duty, financing or adjustment components and other applicable charges.
For a more complete estimate, you can use our Pakistan electricity bill calculator to calculate electricity costs and compare different monthly consumption levels.
TESCO Electricity Tariff and Rates
TESCO consumers are billed according to the applicable electricity tariff notified for their consumer category. Residential consumers are generally placed into different consumption slabs, while commercial, industrial, agricultural and other categories have separate tariff structures.
The rate shown on a bill can also include components that are not simply the base energy price. This is why multiplying units by one advertised per-unit price does not always produce the same amount as the final bill.
Common TESCO Residential Bill Components
| Bill Component | What It Means |
|---|---|
| Energy Charges | Cost of electricity consumed |
| Fixed Charges | Fixed amount applicable to certain consumer categories/slabs |
| Electricity Duty | Government electricity-related duty where applicable |
| GST | General Sales Tax applied according to prevailing rules |
| FPA/Adjustment | Fuel or other periodic adjustment where applicable |
| Quarterly Adjustment | Periodic tariff adjustment where applicable |
| TV Fee | Applicable government television fee where charged |
| Arrears | Previous unpaid amount, if any |
| Late Payment Surcharge | Additional amount for payment after the due date |
| Total Amount Payable | Final amount required to settle the bill |
Why TESCO Bills Change Even When Units Are Similar
Two bills with almost the same number of units can have different totals. This happens because some charges are adjusted periodically.
For example, fuel-related adjustments can increase or decrease the amount payable. Quarterly tariff adjustments can also affect bills after they are notified and implemented.
This makes it important to treat a simple per-unit calculation as an estimate rather than an exact prediction of the final bill.
TESCO Bill Calculation Example
Suppose a household uses 300 units during a billing month.
The calculation begins by identifying the applicable residential tariff category. The energy charge is then calculated according to the tariff structure applicable to that consumer.
A simplified example is:
| Calculation Step | Example |
|---|---|
| Previous meter reading | 10,500 |
| Current meter reading | 10,800 |
| Units consumed | 300 |
| Energy charges | Based on applicable tariff |
| Fixed charges | If applicable |
| Electricity duty | If applicable |
| GST | If applicable |
| Other adjustments | As shown on bill |
| Final bill | Sum of applicable charges |
The exact amount should be calculated using the current tariff applicable to the consumer's TESCO connection.
How to Read a TESCO Electricity Bill
Understanding your bill can help identify unusually high consumption or unexpected charges. Start by checking the meter readings and billing period.
Important fields include:
- Previous Reading: Meter reading recorded during the previous billing cycle.
- Current Reading: Latest meter reading used for billing.
- Units Consumed: Difference between current and previous readings.
- Tariff: Consumer tariff or category applied to the connection.
- Energy Charges: Cost based on electricity consumption.
- Taxes and Duties: Government charges applied to the bill.
- Adjustments: Periodic charges or credits.
- Due Date: Last date for payment without the applicable late-payment charge.
- Payable Amount: Amount shown for settlement of the bill.
If the number of units seems unusually high, compare the current reading with your meter and previous bills before assuming that the tariff is responsible.
TESCO Bill Calculator for Different Consumption Levels
Household electricity usage can change significantly throughout the year. Air conditioners, electric heaters, water pumps, irons, refrigerators and other appliances can increase monthly consumption.
| Monthly Consumption | Typical Usage Pattern |
|---|---|
| 50 units | Very low electricity consumption |
| 100 units | Small household with limited appliances |
| 200 units | Moderate household consumption |
| 300 units | Typical higher residential usage |
| 400 units | Heavy appliance usage |
| 500 units | High monthly consumption |
| 700 units | Very high residential consumption |
| 1,000 units | Extremely high household consumption |
For example, running an air conditioner for several hours every day can add hundreds of kWh to monthly usage. A calculator is useful because it allows you to test different consumption levels before the next bill arrives.
How to Reduce Your TESCO Electricity Bill
Reducing electricity consumption is usually more effective than focusing only on the per-unit tariff. Start with appliances that operate for long periods.
Use Energy-Efficient Appliances
Replace older bulbs with LED lighting and consider inverter air conditioners and energy-efficient refrigerators. These appliances can reduce electricity consumption over time.
Control Air Conditioner Usage
Air conditioning is one of the largest electricity loads in many Pakistani homes. Setting the thermostat around 24–26°C and cleaning filters regularly can help reduce unnecessary consumption.
Monitor Your Meter
Check the meter periodically rather than waiting for the monthly bill. Recording the meter reading every few days gives you a better idea of your daily electricity use.
Avoid Standby Consumption
Televisions, chargers, computers and other devices can consume electricity while they remain connected. Switching off equipment that is not being used can reduce unnecessary consumption.
For broader residential electricity calculations, our Pakistan electricity bill calculator can help you estimate monthly electricity costs from your expected unit consumption.
TESCO Bill Calculator vs Actual TESCO Bill
A calculator provides an estimate, while your official TESCO bill reflects the charges actually applied to your connection.
| Calculator Estimate | Official TESCO Bill |
|---|---|
| Based mainly on estimated units | Based on recorded billing data |
| Uses selected tariff assumptions | Uses applicable notified tariff |
| May exclude periodic adjustments | Includes applicable adjustments |
| Useful for budgeting | Used for actual payment |
| Can compare different consumption levels | Shows actual payable amount |
This distinction is important when planning a household electricity budget. A calculation based only on kWh and a basic tariff cannot always reproduce the exact final bill.
What Information Do You Need for a TESCO Bill Estimate?
For a useful estimate, keep the following information available:
- Previous meter reading
- Current meter reading or expected monthly units
- Consumer category
- Tariff information
- Billing period
- Applicable fixed charges
- Any known government taxes or duties
- Periodic adjustments, if applicable
If you already know your monthly consumption in units, you can start with that figure and then add the applicable bill components.
