Question 1

Why does my actual bill differ from the calculated estimate?

Accepted Answer

FPA, QTR adjustments, GST rounding, and new tariff rates can cause 5-10% differences. Estimates are close but not exact.

Question 2

Can I calculate using my meter reading alone?

Accepted Answer

Yes. Find the difference between current and previous readings. That's your units consumed. Enter in calculator.

Question 3

What's the cheapest LESCO bill possible?

If you consume zero units, you still pay Rs. 75 (fixed charge) + Rs. 35 (TV fee) = Rs. 110 minimum monthly charge.

Question 4

How often do tariff rates change?

Accepted Answer

3-4 times yearly, usually in March, July, and October. NEPRA announces changes in advance.

Question 5

Do I pay the highest slab rate for all units?

Accepted Answer

No. You pay different rates for different slab ranges. The slab system ensures lower rates for lower consumption.

Question 6

Is the online calculator 100% accurate?

90-95% accurate. Actual bill may vary slightly due to additional charges, FPA changes, or billing system delays.
