An electricity tariff table is useful only when it matches your account and billing period. Before using a per-unit figure, identify the supplier, tariff category, meter arrangement and effective date of the schedule. A table copied from a different month or consumer category may produce a plausible but incorrect bill estimate.
This guide explains how to read an applicable schedule. It does not present an unverified “today” rate table. Use your supplier’s bill and the relevant official notification for the rates applied to your account.
Start with the details printed on your bill
- Supplier: use the company name on the account, not the nearest city alone. The company directory links to the available official bill routes.
- Tariff code and category: copy the code and description exactly. Domestic, commercial, industrial and other categories should not be treated as interchangeable.
- Billing period: note the reading dates and billing month. Check whether the document you are reading applies to that period.
- Meter and load details: note any peak/off-peak registers, sanctioned load, demand figures or multiplier shown on the bill.
- Recorded status: if the bill distinguishes a lifeline, protected or another category, ask the supplier which rule and account history support that status rather than guessing it from one month’s consumption.
Separate the rate from the rule for applying it
A slab label by itself does not explain how all units must be charged. Read the category notes, conditions and any stated benefit or exception in the applicable schedule. Do not automatically assume that every slab is a progressive block, or that one selected rate applies to every unit.
To see why the rule matters, consider two invented mathematical methods for 150 units. These are not Pakistan tariff rates or a statement of an applicable billing rule:
- Under a hypothetical block method, 100 units at Rs 10 plus 50 units at Rs 20 would total Rs 2,000.
- If a hypothetical rule instead charged all 150 units at Rs 20, the total would be Rs 3,000.
The same two rate labels can therefore produce different totals. The governing schedule and its conditions decide the applicable calculation; this example cannot decide it for your bill.
Read the columns and notes together
| Item | What to check |
|---|---|
| Variable energy charge | Which units and category does the rate apply to? Is the amount stated per kWh? |
| Fixed or minimum charge | What is the stated basis: connection, load, demand or another condition? Do the notes describe how it interacts with other charges? |
| Time-of-use rates | Which register belongs to each rate? Which seasonal timing, if any, applies to this account and period? |
| Eligibility conditions | What history, consumption, load or account conditions does the actual document specify? |
| Adjustment or relief | Which consumer group and consumption period are covered, and in which bills is it collected or credited? |
| Effective date | Is this the schedule applicable to the bill, or a superseded document, proposal or future change? |
Keep the notes with the table when saving a document. A screenshot containing only rate numbers can omit the conditions needed to interpret them.
The per-unit rate is not the whole bill
Reconcile the bill’s energy charges separately from its other amounts. Fixed charges, adjustments, taxes, balances and credits should each have their own place in the check. Do not multiply the month’s units by an “effective price” copied from someone else’s total bill.
For a simple illustration, a total of Rs 3,000 divided by 100 units is Rs 30 per unit as an average of that total. That arithmetic does not establish a notified energy tariff of Rs 30: the numerator might include amounts unrelated to those units. This example is not a current rate claim.
The bill arithmetic checker can reconcile figures you already have. It accepts one or two units-and-rate rows and amounts you enter yourself. It does not determine slab eligibility, import notified rates or calculate tax percentages.
Where to find the applicable official material
NEPRA’s LESCO tariff record is an example of the company-specific official records containing tariff decisions and adjustment material. Select the record for the supplier concerned and read the document’s subject, category and effective provisions. A fuel-adjustment decision, a distribution tariff decision and a consumer-end schedule answer different questions.
For a K-Electric account, start with K-Electric’s tariff structure page and, when needed, the NEPRA K-Electric record. Do not transfer an adjustment from an ex-WAPDA company’s bill into a KE calculation without checking its applicability.
If you cannot identify the applicable schedule, ask the supplier for the tariff code, source notification and calculation basis used on your bill. Keep the response with that billing period’s documents. A news headline or a hearing notice alone does not supply all of those details.
