How to use this lease buyout calculator

  1. Enter your monthly base rent and the number of months remaining on the lease.
  2. If your lease has an early-termination clause, enter its penalty as a number of months of rent.
  3. Add any unamortized concessions the landlord can recapture (TI allowance, free rent, broker commission).
  4. Compare the two scenarios: stated termination fee vs. full remaining-rent exposure.

The two numbers can be wildly different. The right one for you depends on whether your lease grants an early-termination right — read that section carefully before negotiating.

Lease exit checklist

  • Early-termination clause: Is there a buyout right? What is the fee and how is it calculated?
  • Recapture: Can the landlord claw back unamortized TI, free rent, or commissions?
  • Remedies: What can the landlord pursue if you default — acceleration, re-letting costs, fees?
  • Mitigation: Does your state and lease address the landlord's duty to mitigate by re-letting?
  • Notice & timing: How much advance notice is required, and are there windows to exercise a buyout?

Compare your actual lease language against common patterns in the Clause Library.
