How the math works
Rent abatement = landlord waives or reduces rent for a defined period. Unlike free rent (front-loaded concession), abatement is typically triggered by an event — landlord delay, unfinished buildout, force majeure. Can be 100% (full abatement) or partial (50% rent for 3 months).
Document the trigger and release conditions carefully. Vague abatement clauses are the #1 commercial lease dispute — be specific about when abatement starts and when it ends.
How to Use
- Enter monthly rent and abatement duration in months.
- Enter abatement percentage (100% full, 50% partial, etc.).
- Pick a reason bucket to contextualize the trigger.
- Read total abatement value and effective rent.
Frequently Asked Questions
Abatement vs free rent?
Free rent is a negotiated signing concession; abatement is triggered by a specific event or clause — landlord breach, casualty, substantial completion delay. Abatement terms appear in force majeure, default, and construction delay sections of the lease.
Partial abatement use cases?
Tenant can occupy the space but only partial use (e.g., 50% square footage ready). Landlord and tenant typically negotiate partial % matching the functional impairment.
Does abatement affect CAM or property tax?
Usually only base rent. CAM and real estate tax pass-throughs typically continue during abatement unless explicitly waived — check the abatement clause wording.
