Annual Interest Expense — Methodology and Sources

Last reviewed: 2025-05-20

What this measures

Annual interest expense of the Victorian general-government sector, as reported in Budget Paper 2. Captures the cost of servicing accumulated debt — distinct from new borrowing.

How values are derived

Reported directly in BP2 in nominal $bn. Real values deflate using RBA all-groups CPI (base FY 2023-24). Per-capita uses ABS ERP at 30 June.

Why this matters

Interest is the visible annual cost of past debt decisions. Even if net debt stabilises, interest continues to compound until debt is repaid. The benchmark caption converts the abstract $bn figure into a service-cost equivalent so readers can size it intuitively.

Caveats

  • Interest is sensitive to RBA rate decisions, not just debt levels.
  • The benchmark used in the caption (Vic Police operating budget, public-hospital recurrent budget) is an approximate equivalent for intuition; both are sourced from BP3 operating outlays.
