How to use

Enter units consumed — from your meter reading (current − previous).

Read the breakdown — energy per slab, surcharges and taxes, with the total your bill should be near.

About this tool

Pakistani power tariffs are slab-based: units are billed in tiers (e.g., first 100 units cheapest, above 700 most expensive) and taxes stack on top. Because rates change by notification and differ between LESCO, KE, GEPCO and other DISCOs, this tool ships with an example tariff and lets you edit every slab and tax from your latest bill — making the estimate match your area exactly. Honest note: the output is an estimate for budgeting; fuel-price adjustments applied retroactively by your DISCO can differ.

FAQ

Why do my numbers differ slightly from the actual bill?

DISCOs apply fuel-price adjustments (FPA) and quarterly tariffs retroactively, and meter rent or TV-fee lines vary. Edit the tax fields from your latest bill to align the estimate.

What are slab tariffs?

Units are billed in tiers: e.g., first 100 units at one rate, 101–200 at a higher rate, and so on — you pay each tier's rate only for the units inside it. The tool computes each slab separately.

Which companies does this cover?

Any Pakistani DISCO (LESCO, KE, GEPCO, FESCO, HESCO…) because every rate field is editable — match the numbers printed on your bill.

Is protected-consumer logic included?

If your bill shows a 'protected consumer' flat tariff, replace the slabs with that single rate — the calculator handles any single- or multi-slab setup.

Can I estimate before the bill arrives?

Yes — read your meter, enter the units consumed so far, and you get an expected total using the current slabs.

Is any data uploaded?

No. Your consumption and rates never leave this page.
