Enter the proposed renewal dates, rent, and terms to calculate the change and generate a neutral renewal offer letter.
NumPad does not determine whether a renewal, rent change, notice period, or response deadline is legally valid. Check the lease and official state and local rules before sending the letter.

Methodology and limitations
What NumPad calculates. Rent dollar change equals proposed renewal rent minus current rent. Percentage change equals dollar change divided by current rent, multiplied by 100. Date intervals use calendar-day differences between the dates entered. Fixed terms are summarized in calendar months and remaining days, with the exact inclusive calendar-day count retained as a secondary reference.
Limitation. NumPad generates a renewal letter from the dates, rent, and terms you enter. It does not determine whether a proposed renewal, rent change, notice period, or response deadline is legally valid.
Rules that may apply. The lease itself, state and local law, rent-control or stabilization rules, property type, subsidy status, tenancy status, delivery method, and proposed changes may affect requirements.
State guidance. State selection is research-only. Check your lease and applicable state/local rules to determine any required notice or response period.

How the generator uses entered dates and rent—and where its legal guidance stops.
NumPad does not select a notice period, and there is no universal federal 30-day renewal-notice rule for ordinary private residential leases. Requirements may depend on the lease, state and local law, tenancy status, property type, rent-control coverage, delivery method, and the kind of change proposed.
