AUD then vs now — purchasing power calculator

Turn “what did A$X buy in year Y?” into a clear estimate for Slack, wage chats, or nostalgia. Approximate AU CPI series — conversation tool, not the official RBA calculator.

Then-vs-now calculator

Equivalent purchasing power—
Price-level multiplier—
% change in price level—
CPI indexes used (from → to)—

Formula: Amount × (CPIto ÷ CPIfrom). Swap the years to go now → then. Estimates only — not official ABS/RBA output. Share this scenario by copying the address bar (updates as you type).

Argument kit for Slack / your manager

Offline pack: editable CSV + refresh guide + a forwardable one-pager you can drop into Slack or email. Same approximate AU series — reusable without this page. Not “better CPI than RBA”; it’s the kit you send when someone asks “got a source?”
