Financial Calculation Rules

This skill defines the canonical business logic for financial data display in Varisankya.

1. Remaining Monthly Liability (Hero Card)

The "Remaining" amount displayed on the Home Screen Hero is NOT just future payments.

Formula:

code
Remaining = (Sum of All Overdue Items) + (Sum of Unpaid Items Due Today or Later in Current Month)

Critical Rules:

  1. •Include Overdue: Any unpaid subscription from the past is an immediate liability and MUST be included in the "Remaining" count.
  2. •Current Month Boundary: Future items are only included if they fall within the current calendar month. Next month's rent is NOT "Remaining" (it is "Upcoming").
  3. •Strict "Before" Check: "Overdue" is defined strictly as dueDate < today (start of day).

2. Widget "Upcoming" Logic

The Home Screen Widget displays the "Top 3" most relevant payments.

Sorting Priority:

  1. •Overdue First: Oldest overdue item is top priority.
  2. •Due Soon: Then items sorted by closest future due date.

3. "All Clear" State

The "All Clear" state (Green Hero) should ONLY trigger if:

  • •Overdue List is Empty AND
  • •Current Month Future List is Empty.

If there are no current month payments but there IS an overdue payment from last year, the state is Overdue (Red), not All Clear.
