Estimate Your Domestic Electricity Bill (Independent Tool)
MEPCODBill's bill calculator is an independent planning tool for households in the MEPCO service area (Multan, Bahawalpur, Sahiwal and surrounding districts). It does not claim to be the official MEPCO website and does not fetch live official bill data. Enter your units and adjustments to get a budgeting estimate before the printed invoice arrives.
The estimate follows published domestic slab concepts from NEPRA tariff schedules, then layers FPA, QTA, electricity duty, GST and PTV fee using the rates you supply. Treat the total as an approximation you can compare line-by-line with your official bill.
How the Calculator Works (Step-by-Step)
Domestic consumers are grouped as Lifeline, Protected, or Unprotected. When you enter consumed units (kWh) and a category, the tool maps that usage to an assumed slab rate and fixed charge, then adds the variable and tax components you provide.
Step-by-step estimate:
- Pick a category — Lifeline, Protected, or Unprotected (as shown on your last bill).
- Enter units — total kWh for the billing period (from your meter difference or last bill).
- Set FPA & QTA — copy Rs/unit figures from a recent bill; leave at zero if unknown.
- Energy + fixed — units × assumed slab rate, plus the matching fixed charge.
- Taxes & fees — approximate ED (~1.5%), 18% GST on taxable parts, and Rs. 35 PTV fee.
- Total — sum shown as an estimated payable amount for planning only.
Inputs Explained
- Consumer category — controls which assumed rate table the tool uses. Protected/Lifeline rates only apply if you still qualify under NEPRA rules.
- Units consumed — kilowatt-hours for the month. Pair with the meter reading calculator if you only have dial numbers.
- FPA / QTA rates — rupees per unit from your bill. These change by notification and are the biggest cause of estimate drift.
Formulas in Plain English
Energy cost ≈ units × slab rate
FPA / QTA ≈ units × (your FPA + QTA rates)
ED ≈ 1.5% of energy cost · GST ≈ 18% of taxable subtotal · + fixed + PTV
Tariff Slabs & Fixed Charges (Planning Table)
Domestic unprotected rates rise with higher slabs, and fixed charges recover capacity costs. Figures below are planning assumptions for unprotected domestic consumers — always confirm against the current NEPRA schedule:
| Unit Range (Slab) | Rate Per Unit (Rs.) | Monthly Fixed Charge |
|---|---|---|
| 01 - 100 Units | 22.44 | Rs. 275 |
| 101 - 200 Units | 20.91 | Rs. 300 |
| 201 - 300 Units | 33.10 | Rs. 350 |
| 301 - 400 Units | 36.46 | Rs. 400 |
| 401 - 500 Units | 38.95 | Rs. 500 |
| 501 - 700 Units | 40.22 - 41.85 | Rs. 675 |
| Above 700 Units | 47.20 | Rs. 675 |
About these figures
- Rates shown are planning assumptions for unprotected domestic consumers and exclude GST, Electricity Duty, PTV fee, FPA and QTA.
- These are estimates for planning only. This site is not a NEPRA or MEPCO source, and figures can differ from the notification in force for your billing month.
- Official totals also differ due to FPA/QTA revisions, arrears, ToU splits, meter rent and fixed charges. Always treat your printed bill as authoritative.

Understanding Taxes & Surcharges
It is a common point of frustration for electricity consumers in Pakistan to see a bill that is sometimes 40% to 50% higher than the actual cost of electricity consumed. This disparity is birthed by an array of government taxes and surcharges. The most impactful of these is the General Sales Tax (GST). Mandated at 18%, this tax is not just levied on the base cost of electricity, but it cascades over the fixed charges, Fuel Price Adjustments (FPA), and Quarterly Tariff Adjustments (QTA), creating a compounding effect on your pocket.
Additionally, the Electricity Duty (ED) is a provincial tax applied at roughly 1.5% of the variable charges. There is also the mandatory Pakistan Television (PTV) fee of Rs. 35 added to every domestic connection regardless of consumption volume. For commercial consumers, Income Tax and Extra Tax are also integrated, though this calculator focuses strictly on the domestic residential sector.
When Results Differ from Official Bills
Expect differences. Official invoices can include arrears, meter rent, late-payment surcharge, instalments, solar netting, ToU peak/off-peak splits, and revised FPA/QTA for that month. This tool uses a simplified domestic non-ToU model. For Time-of-Use connections use the peak/off-peak calculator. Deeper tax context: NEPRA taxes & FPA guide.
FPA and QTA (Why Estimates Move)
To get a closer estimate, understand FPA and QTA. The Fuel Price Adjustment (FPA) passes fluctuating generation fuel costs to consumers when actual cost differs from the reference. A positive FPA is added later as Rs/unit.
The Quarterly Tariff Adjustment (QTA) reflects capacity, losses and DISCO cost variations recovered over a defined period. Copy both rates from your latest bill into the form for a better approximation — they are revised by notification and will not always match last month.
How this estimate works
Core logic
Energy ≈ units × slab rate; FPA/QTA ≈ units × (your rates); then + fixed + ED (~1.5%) + GST (~18%) + PTV
Assumptions
- Domestic non-ToU slab model using planning rates for Lifeline / Protected / Unprotected categories
- FPA and QTA are user-supplied Rs/unit inputs (defaults are editable approximations)
- ED, GST and PTV fee use simplified percentages/fees for budgeting
Limitations
- Not an official NEPRA or MEPCO billing engine — totals are planning estimates only
- Does not model arrears, meter rent, late-payment surcharge, instalments, solar netting or ToU peak/off-peak splits
- Slab rates and fixed charges can differ from the notification in force for your billing month

Frequently Asked Questions (FAQs)
How can I retain my 'Protected Consumer' status?▼
Protected / Lifeline eligibility is defined in NEPRA tariff determinations and can change. As a planning rule of thumb, many domestic consumers treat staying under about 200 units for consecutive billing months as important for retaining lower protected rates — but confirm the threshold, consecutive-month rules and any reclassification effects on your printed bill or the NEPRA schedule. Do not rely on this page for subsidy status decisions.
Why is the bill calculation slightly different from my official MEPCO bill?▼
Because this calculator is an independent approximation of published slab concepts, not a copy of MEPCO's billing system. Official bills often include arrears, meter rent, late-payment surcharge, instalments, solar netting and ToU peak/off-peak splits. FPA and QTA also change by notification. Copy rates from your latest bill into the form, then verify line-by-line against the next invoice — expect a ballpark, not a match.
Are the fixed charges applicable if my consumption is zero?▼
Many domestic tariff schedules still apply a monthly fixed / capacity-related charge and a PTV fee even when metered units are zero, but the exact amount depends on your consumer category, sanctioned load and the notification in force for that billing month. Treat the fixed-charge line in this tool as a planning assumption — confirm the figure printed on your bill and the NEPRA tariff schedule.
How does Time of Use (ToU) differ from this calculator?▼
This calculator assumes a standard domestic (non-ToU) connection. ToU meters — typically installed at higher sanctioned loads — bill peak and off-peak units at separate flat rates instead of running everything through the slab ladder, so a slab estimate will misread them. Peak windows shift by season and are set by notification, so read the window off your own bill rather than assuming a fixed evening block. For those connections use the peak / off-peak calculator, and see the ToU peak hours guide for how the windows work.
