Rent Increase: Amount and Notice Timing

The percentage calculator subtracts current rent from proposed rent, divides by current rent and multiplies by 100. Annual impact multiplies the difference by 52 weekly or 12 monthly payments. It does not determine notice validity.

The notice checker uses the date you say notice was received or served, not the date a letter was posted. Calendar-month rules require calendar counting, not a fixed number of days. Queensland action dates also require next-day and business-day/public-holiday handling, so this checker does not evaluate automatic Queensland dates. Delivery rules, prescribed forms, contractual clauses and challenges require separate verification.

The checker compares current ordinary residential-tenancy minimums only within each source's scope. Victoria's 90-day rule is effective from 25 November 2025; Queensland uses two calendar months; the NT uses a six-month interval. Older agreements, fixed-term clauses, social housing and exempt tenancy types may need a separate review. Tasmania remains source-review-required because its statutory boundaries use different strict inequalities. Queensland dates remain source-review-required until action-day and public-holiday counting is covered.

Timing that meets these comparisons does not prove the increase is lawful. Queensland's interval follows the property, so a renter's own previous increase date may not establish the full history.
