How We Calculate MEPCO Bill Estimates
Last checked 26 September 2026
Every bill amount on MEPCO Bill Checker, in the calculator and on the guides, comes from one set of official figures kept in a single data file. This page lists each line we calculate, the official source behind it, what we leave out, and how the figures are kept up to date.
The lines in every estimate
An estimate is built line by line in the same order as a MEPCO bill. Each row below is one line, with its official source:
| Line | How it is worked out | Official source |
|---|---|---|
| Cost of electricity | Units multiplied by the rate for the category and slab. Un-protected homes pay one rate on every unit; protected homes keep the lower rate on their first 100 units. | NEPRA decision of 11 February 2026, notified as S.R.O. 279(I)/2026 |
| Fixed charges | Rate per kW for the slab multiplied by the sanctioned load; time-of-use meters use 50% of the load or the MDI, whichever is higher. Lifeline homes pay none. | Same decision, notes to Annex-A-1 |
| Fuel charges adjustment | This month's rate per unit, applied to the units you enter. On a real bill it is charged on an earlier month's units. | NEPRA's monthly fuel adjustment decision |
| Quarterly adjustment | This quarter's rate per unit. | NEPRA's quarterly adjustment decision |
| Debt servicing surcharge | Rs 3.23 a unit, Rs 0.43 for protected homes, none for lifeline homes. | NEPRA decision of 30 March 2023 under section 31(8) of the NEPRA Act |
| Electricity duty | 1.5% of the cost of electricity and fixed charges. | Provincial duty, as printed on 2026 MEPCO bills |
| General sales tax | 18% of the total of the lines above. | Sales Tax Act, 1990, sections 2(46) and 3 |
The rates currently in use are listed on the MEPCO tariff 2026 page, and you can run your own figures in the MEPCO bill calculator.
What the estimates leave out
These amounts depend on your own account, so no estimate can include them:
- income tax, which applies only when a home bill reaches Rs 25,000 and the consumer is not on FBR's Active Taxpayers List;
- arrears, installments and deferred amounts from earlier bills;
- the late payment surcharge;
- corrections, detection charges or any other line MEPCO adds to a particular account.

How the figures are checked and updated
- Official sources only. Rates, fees, time limits and rules are taken from NEPRA, MEPCO, PITC, FBR and government documents. News reports are used only to report what someone announced, with the outlet and date. Other bill websites are never used as a source.
- A record for every claim. Each guide has a claim record listing every fact on the page and the document, page and clause it comes from.
- A separate check. Every guide is reviewed by a second checker against the same documents before it is published.
- Monthly updates. NEPRA sets a new fuel adjustment each month and a quarterly adjustment each quarter. When a new decision is published, the rates and every estimate on the site are updated together.
