A tool that answers one question honestly: what does a unit of electricity actually cost you, once every tax, duty and surcharge is counted?
Ask what electricity costs in Pakistan and you get a slab rate — something like Rs 10.54 per unit for the first hundred units. Almost nobody pays that. By the time your bill is printed it has collected a fuel price adjustment, a quarterly tariff adjustment, a financing-cost surcharge, fixed charges based on your sanctioned load, electricity duty, general sales tax, a PTV fee, and — if the bill crosses Rs 25,000 and you are not on the active taxpayer list — 7.5% advance income tax.
The result is that the number people quote and the number people pay are different by a wide margin, and the bill itself does not show you the gap. This calculator does. It gives you one figure — the effective cost of one unit at your level of usage — and then shows the full line-by-line breakdown underneath it, so you can see exactly which component is doing the damage.
A common misconception is that IESCO, LESCO, FESCO, MEPCO, GEPCO, PESCO, HESCO, SEPCO, QESCO and TESCO each have their own residential rates. They do not. NEPRA determines a uniform national tariff that applies across all of them, and K-Electric is aligned to it. Anyone showing you a different rate table per company is either out of date or selling something.
That is why the company selector on the calculator changes so little: it matters for the autofill lookup and for provincial electricity duty, not for the underlying slab rates.
The Rates last updated panel on the calculator always shows when each figure was last verified. If you want to override anything with the exact numbers from your own bill, open Adjust monthly rates and type them in.
The model is built against real bills and reproduces them closely, but it is an estimate and a few things are honestly worth knowing:
Autofill is the way to get this exact: it pulls the real figures off your actual bill rather than relying on national averages.

If you are reporting an inaccurate estimate, it helps enormously to include your units, sanctioned load, consumer category and the bill total you were actually charged. Please do not email your reference number — it is not needed to investigate.
