How to use this lease buyout calculator
- Enter your monthly base rent and the number of months remaining on the lease.
- If your lease has an early-termination clause, enter its penalty as a number of months of rent.
- Add any unamortized concessions the landlord can recapture (TI allowance, free rent, broker commission).
- 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?
