First Home Buyer Calculator Australia

Buying your first home involves more than just loan repayments. This calculator estimates first home buyer grants, stamp duty savings, and deposit requirements based on your location and purchase details.

Results are based on public government schemes and typical lender assumptions.

Estimate:

  • First home buyer grants
  • Stamp duty savings
  • Minimum deposit needed to buy

Buying your first home can involve grants, duty savings and low-deposit schemes - but rules vary by state and may change. This calculator gives an estimate based on your inputs and current public guidance.

What may help you buy sooner

  • You may qualify for a first home buyer grant of around $10,000.
  • Stamp duty may be reduced or fully waived depending on your state and property value.
  • A 5% deposit pathway may be available through federal schemes if key checks are met.
  • Some buyers may avoid LMI through government guarantees, subject to lender participation.

Important assumptions

  • Baseline duty is an estimated market-rate proxy for educational use in V1.
  • Grant estimates are indicative only and depend on final state criteria and evidence.
  • No contract date entered, so current date is used for date-sensitive scheme windows.
  • Results are based on self-entered details and public guidance.
  • Some scheme checks still depend on lender, legal, and state details not modelled in V1.

How this calculator works

The calculator normalizes your buyer and property inputs, applies a data-driven rules engine for federal and selected state pathways, estimates first home buyer grants and stamp duty savings, then builds an upfront-cash summary with assumptions and source links.

What government schemes may apply

V1 models federal 5% deposit support, Help to Buy relevance, FHSS educational prompts, and selected state concessions for NSW, VIC, and QLD to estimate first home buyer grants and stamp duty savings by state.

State-based differences

State eligibility criteria differ across duty thresholds, grant amounts, occupancy conditions, and definitions of new homes or substantial renovations.

Important assumptions and limitations

  • Eligibility statuses are expressed as likely, possible, or not eligible based on inputs.
  • This is not an official entitlement or lender assessment tool.
  • Some duty savings are estimated in V1 to avoid false precision.
  • Rules can change and may be updated at different times by each authority.

Official sources

Source links are embedded in the rules layer and surfaced in results so updates can be maintained through data revisions instead of UI rewrites.
