Rate Lock Expiry Countdown Planner
Keep closings on schedule by mapping your mortgage rate lock start date, lock length, and targeted closing date. The planner computes the expiration date, buffer or gap days, highlights a reminder date, and estimates extension fees if the timeline slips beyond the lock.
Outputs are illustrative. Always confirm lock expiration, extension pricing, and float-down policies with your lender.
Examples
- Lock start 2026-04-15, length 60 days, closing 2026-06-20, fee $45, reminder 10 days ⇒ Rate lock expires on 2026-06-14. Closing on 2026-06-20 leaves a gap of 6 days. Loan timeline from lock to closing spans 66 days. Schedule milestone reminders for 2026-06-04 (reminder 10 days before expiry). Extension of 6 days costs $270.00.
- Lock start 2026-03-01, length 45 days, closing 2026-04-05, fee blank, reminder blank ⇒ Rate lock expires on 2026-04-15. Closing on 2026-04-05 leaves a buffer of 10 days. Loan timeline from lock to closing spans 35 days. Schedule milestone reminders for 2026-04-05 (reminder 10 days before expiry).
FAQ
How do I account for float-down options?
Include the float-down cost in the extension fee input or note it separately if the lender allows a one-time float without extra fees.
Can I track multiple milestones?
Use the reminder date as an anchor, then back into appraisal, underwriting, and clear-to-close tasks relative to that milestone.
What if I re-lock at a later date?
Enter the new lock start and length after re-locking. The calculator will recompute the expiry, buffer, and fee impact instantly.
Additional Information
- Lock expiration assumes calendar days and does not adjust for bank holidays; confirm with your lender for state-specific rules.
- Reminder buffer defaults to 10 days so you can nudge appraisals, underwriting, and doc signing before the lock lapses.
- Extension fees are calculated per day; if your lender quotes per 5-day blocks, divide the block fee by days and enter the daily equivalent.
