FESCO Bill Calculator 2026 – Instant Bill Estimate
A FESCO bill calculator works out your Faisalabad Electric Supply Company charges by running your monthly units through NEPRA’s domestic slab rates, then adding fixed charges, GST and the current Fuel Price Adjustment. Type in your units below and the estimate updates as you type — no login, no waiting for the actual bill.
How the slab math actually runs
Energy charges are worked out slab by slab: your first 100 units are billed at the 1–100 rate, the next 100 at the 101–200 rate, and so on. Your whole month isn’t billed at one flat rate.
Where the real jump happens is the protected/non-protected line, and it’s a different mechanism entirely. Stay at or under 200 units across your last six bills and you keep subsidised rates. Cross 200 in a single month and that entire month reprices at non-protected rates — not just the units past 200. A move from 195 to 210 units can add thousands of rupees to the total, and that’s not a calculator glitch, it’s how the tariff is structured.
What this estimate includes — and what it doesn’t
The numbers above cover energy charges, fixed charges, GST, the FC surcharge, the PTV fee and whatever FPA figure you enter. It leaves out arrears, income tax deductions, meter rent and the quarterly QTA adjustment, since those sit on your specific account rather than the standard tariff formula. For the full line-by-line layout — FPA, QTA, TR surcharge and all — see how it reads on an actual bill.
If you’re weighing a new meter rather than reading an existing one, keep in mind the fixed-charge slab your future bill lands in follows the load you apply for, which is worth checking before you submit the paperwork.
A quick FAQ
Is this the same figure as my official bill?
No. FPA isn’t fixed until NEPRA notifies it each month, so treat this as a planning number, then confirm once your bill is issued.
Why did my estimate jump sharply past 200 units?
You crossed into non-protected billing. The higher rate applies to the whole month, not the units above 200.
Does it work for commercial or industrial connections?
No — it’s built around the domestic (A-1) tariff. Commercial and industrial connections follow a separate rate structure.
Tariffs get revised every quarter and FPA shifts almost every month, so cross-check the live per-unit figures at nepra.org.pk before making a decision based on this estimate.
