Assumptions used

  • The entered date is the date of effective service in person.
  • The date uses two calendar months of notice and 52 weeks from the previous increase.
  • A missing corresponding notice day moves to the first day of the following month. Monthly rental periods use the last day of a short month.
  • The historic annual anchor entered is 2026-02-01; Form 4A’s six-day drift test determines the 52- or 53-week minimum.

Rates as of
