How This Calculator Works
Lease End Date = Lease Start Date + Lease Term (in months). Notice Deadline = Lease End Date minus the Notice Period Required (in days). Days Until Notice Deadline and Days Remaining in Lease are both measured from today's date. Lease Term Elapsed = (days since the start date ÷ total days in the lease term) × 100, held between 0% and 100%.
Frequently Asked Questions
- How do I calculate my lease end date from the start date and term length?
- Add the lease term in months to the start date. A 12-month lease starting January 1 ends December 31 of the same year — not January 1 of the following year, a common off-by-one mistake. Always check what your specific lease defines as the end date, since some leases end on the last day of the prior calendar month instead of a fixed anniversary date.
- How much notice do I need to give before my lease ends?
- Notice periods are set by your lease and, for residential tenancies, sometimes by state law as well. Common defaults are 30, 60, or 90 days before the lease end date, but your lease can require more. Commercial leases frequently require 90 to 180 days. Check your lease's notice or renewal provision directly rather than assuming a default period applies.
- What happens if I miss my lease's notice deadline?
- Many leases include an auto-renewal clause that extends the lease, often for another full term, if notice isn't given by the deadline, while others convert automatically to a month-to-month tenancy. Staying past the lease end date without a new signed agreement can also trigger holdover rent, which is often charged at a premium above normal rent.
