Oz Finance Hub is a web based platform providing a collection of calculators and tools for Australian tax and personal finance. Its primary function is to help users estimate take home pay, tax obligations, superannuation, HELP/HECS repayments, stamp duty, mortgage costs, and other financial figures using current ATO rates. The calculators are built on rates and thresholds updated for the 2026–27 financial year, and the date of verification is displayed on each page. The site operates as a free resource with a premium tier that allows users to save calculation results, compare two scenarios side by side, and generate PDF records for tax time. The tool library covers categories such as income and tax, retirement and super, student loans, investments, family and benefits, and planning for new arrivals to Australia. All calculations are performed on the user’s device; entered data is not sent to a server unless the user chooses to save a run with a premium account. The site also includes a feature that shows suburb affordability based on actual recent sale prices, comparing income levels from specific occupations to median property prices across thousands of suburbs. Typical use cases include estimating net salary after tax, Medicare levy, and HELP repayments; comparing home loan options or stamp duty costs; planning EOFY contributions; and assessing retirement savings or investment scenarios. Users can start with any calculator without signing up, and premium subscribers can reopen saved scenarios later or share clean records with an accountant. The site includes a disclaimer noting that all results are estimates for general information only and do not constitute financial, tax, or personal advice. It does not hold an AFSL and recommends consulting qualified professionals for individual circumstances.
