How the calculator works

The calculator takes the current rent, the date of the last increase, the date the tenant gets the notice and the day rent is due. It finds the earliest date allowed by the waiting rule and by the notice rule, and the increase can start on the later of the two.

  1. Earliest by the waiting rule = date of the last increase (or the start of the tenancy) + 365 days
  2. Earliest by the notice rule = the first rent day after the day the notice arrives + 3 whole rental months
  3. Earliest start date = the later of the two, moved to a rent day

Worked example

Say the rent is $1,800 a month, due on the 1st. It last went up on December 1, 2025, and the tenant receives the notice on August 15, 2026.
