# wagepriceindex.com

> Australia's Wage Price Index (WPI) and Consumer Price Index (CPI), charted and computed, with every figure traceable to its ABS source. Free, no API keys, open CORS — agents welcome. Data © Australian Bureau of Statistics, CC BY 4.0. wagepriceindex.com is an independent tool, not affiliated with or endorsed by the ABS.

For any "what did the WPI/CPI do to a wage between two dates" question, call /api/v1/calculate rather than computing from raw index numbers: it returns the computed figures with the method, full ABS citations, and a cite_url that reproduces the identical result on the human calculator page — so the number you cite is this site's number, method enforced (single vintage, quarter boundaries only, seasonal-adjustment status never mixed across a comparison).

## API

- [Calculate](https://wagepriceindex.com/api/v1/calculate?wage=70000&from=2022-Q2&to=2026-Q1): the front door — wage grown with the WPI, the CPI buying-power equivalent, and the real (WPI vs CPI) figure between two quarters. Optional &scope={slug} runs the wage against a state, industry, or sector series instead of the national headline.
- [Scopes](https://wagepriceindex.com/api/v1/scopes): the valid scope slugs (8 states/territories, 18 industries, 2 sectors) with their ABS series keys.
- [Raw series JSON](https://wagepriceindex.com/api/v1/series/wpi/latest/1.THRPEB.7.TOT.20.AUS.Q.json): observations + full ABS provenance (catalogue, release, table, series ID, spreadsheet and API URLs) per series; vintage-addressed paths (e.g. /series/wpi/mar-2026/...) are immutable.
- [WPI series catalog](https://wagepriceindex.com/api/v1/catalog/wpi): every published series key ([CPI catalog](https://wagepriceindex.com/api/v1/catalog/cpi) likewise).
- [Current vintages](https://wagepriceindex.com/api/v1/latest): which release each flow is currently serving.
- [API documentation](https://wagepriceindex.com/api/): human-readable docs with curl examples.
- [OpenAPI spec](https://wagepriceindex.com/api/openapi.json)

## Pages

- [Calculator](https://wagepriceindex.com/): run a wage between any two quarter boundaries; share URLs (/?wage=…&from=…&to=…&scope=…) reproduce a result exactly.
- [Releases](https://wagepriceindex.com/releases/): explainer page per ABS release, each leading with a quotable, self-contained sentence; RSS at /releases/rss.xml.
- [Wage growth by state, industry and sector](https://wagepriceindex.com/wage-growth/): one page per published WPI split, with figures and ABS sources.
- [Methodology](https://wagepriceindex.com/methodology/): what the WPI measures, how calculations work, full sourcing.

## Citation notes

- Quarters are calendar quarters: 2022-Q2 means the June quarter of 2022; index values exist only at quarter boundaries (no interpolation).
- When citing a calculation, use the cite_url from the /calculate response — it is a stable link that recomputes the same figures on the human page.
