Read the period before the amount
The bill can show an FPA rate, the units to which it applies, and a reference month. Use those printed values together. Do not assume the current billing month’s units are always the correct base.
Positive, negative or absent
A positive line increases the bill; a negative line is a credit. A blank or absent FPA is not the same as a verified zero rate. The calculator therefore defaults it to “not included.”
What to compare
- Reference month and applicable units
- Rate per unit and total FPA line
- Any separately printed tax or duty on the adjustment
- The relevant NEPRA monthly decision
