PESCO Bill Calculator 2026 – Estimate by Units
The PESCO Bill Calculator turns your monthly units into an estimated bill in seconds. Enter the units you have used, choose your consumer category, and it applies the current NEPRA slab rate plus every tax and surcharge to show what you are likely to owe — before your official bill is generated on PITC. One input decides how close the estimate lands: this month’s Fuel Price Adjustment. Add it, and a rough guess becomes a figure you can budget against.
Estimate only. Actual bill varies with monthly FPA, quarterly adjustments, arrears and any govt relief. Confirm from your official PESCO bill.
What to enter — and where to find it
Three inputs drive the result.
- Units. Subtract last month’s meter reading from your current reading. No meter in front of you? Copy the “units consumed” figure from your latest statement — the quickest route is to open your latest bill and read it off the top section.
- Category. Protected means 200 units or fewer in every one of the last six months. Anyone else is non-protected. This single choice can double your energy charge, so set it honestly.
- FPA (Rs/unit). The fuel adjustment changes every month. It sits as a line item on your last bill, or in NEPRA’s monthly notification. Leave it at zero and the estimate will read low.
A worked example, so you can trust the total
Take 350 units on a non-protected connection, with FPA near Rs 3:
- Energy: all 350 units bill at the 301–400 rate (about Rs 27.94), not only the units above 300 → ≈ Rs 9,779
- FPA: 350 × 3 → Rs 1,050
- FC surcharge + Neelum-Jhelum, both charged above 200 units → ≈ Rs 1,166
- GST 17% on those charges → ≈ Rs 2,039
- Electricity duty (1% in KP), meter rent and TV fee → ≈ Rs 168
- Estimated total ≈ Rs 14,200
Seeing each line is the point. You know which charge pushes the bill up, not just the final number.
Why one extra unit can cost you thousands
Once you are non-protected, PESCO prices your whole consumption at a single slab. Cross a boundary and every unit re-prices — not just the extra one.
Run 300 units and your estimate sits near Rs 10,100. Run 301 and it climbs past Rs 12,200. One unit over the line adds more than Rs 2,000. The calculator lets you test these thresholds ahead of the meter reading, so you can hold usage just under a boundary in the closing days of a billing cycle.
Estimating before you have a reading
Planning for a new appliance or a fresh meter? Work out the units first:
watts × hours per day × 30 ÷ 1,000 = units per month
A 1.5-ton inverter AC (around 1,200 W) running eight hours a day adds roughly 288 units. Drop that on top of your usual load in the calculator to see the true cost of switching it on. Setting up a brand-new meter with no history to copy from? Estimate the household’s monthly units this way before you apply for a new connection, and go into the first bill with your eyes open.
Why your estimate won’t match to the last rupee
A calculator applies standard rates; a real bill carries live adjustments. Yours can differ because FPA is finalised after the month ends and billed roughly two months late, a quarterly adjustment or government relief shifts the rate, arrears or a late-payment surcharge carry over, or a Time-of-Use meter splits your units into peak and off-peak. Treat the result as a planning figure. The amount on your PITC statement is the one you pay.
FAQs
How accurate is the PESCO Bill Calculator?
Within a few hundred rupees when your units, category and FPA are correct. The usual gap is the monthly FPA and any unpaid arrears.
How do I find my units for the calculator?
Current meter reading minus last month’s reading — or the “units consumed” line on your latest bill.
Why is my estimate lower than the actual bill?
Common causes: arrears carried forward, a higher FPA than you entered, or being charged non-protected rates after crossing 200 units in a recent month.
