What this calculator does

This calculator finds your exact lease end date from a start date and term length, and works backward from that date using your required notice period to show the last day you can submit notice to vacate — helping you avoid an unwanted automatic renewal or lease-break penalty.

Worked example

A 12-month lease starts on June 1, 2026, ending on May 31, 2027. With a60-day notice requirement, the deadline to give notice is April 1, 2027.

Common mistakes

  • Off-by-one lease end dates. A 12-month lease from June 1 ends May 31 of the next year, not June 1 — that date marks the start of a new term.
  • Missing the notice deadline. Many leases auto-renew or convert to month-to-month if written notice isn't received by the deadline, even by a single day.
  • Assuming verbal notice is sufficient. Most leases require written notice — a phone call or verbal mention typically doesn't satisfy the requirement.

Frequently asked questions

Is the lease start date counted as day one?+

Yes. A 12-month lease starting January 1 ends on December 31 of the same year — the day before the anniversary of the start date — not January 1 of the following year.

How do you calculate a notice-to-vacate deadline online?+

We subtract your required notice period (in days) from the lease end date, giving you the last day you can submit written notice while still meeting the requirement.

What if my lease automatically renews?+

Many leases convert to a month-to-month or renewed term automatically if notice isn't given by the deadline. Check your lease's renewal clause — this calculator only projects the fixed-term end date and notice deadline.

Does this calculator account for local tenant law?+

No — required notice periods vary significantly by jurisdiction and lease type. Enter the notice period specified in your lease or required by your local tenancy law.
