How damages are usually measured

When a commercial tenant breaks a lease, the landlord's claim usually starts with rent that has come due and gone unpaid. Future rent depends on the lease, especially whether it has an acceleration clause, and on the state's rules about mitigation: many states require the landlord to try to re-let and credit the new rent, and the costs of re-letting (commissions, tenant improvements, landlord's work) are often recoverable. Tenants' claims run the other way, for rent abatement or damages when a landlord fails to repair, locks the tenant out without following the required process, or interferes with the tenant's use. A fee-shifting clause can move the result more than any single claim.

General background, not legal advice; the rules vary by state and by the documents in your deal.

What the calculator asks about

These are the facts it pulls from your description or documents for a commercial lease dispute:

  • Property state
  • Unpaid rent accrued to date
  • Does the tenant dispute the debt?
  • Is there a written lease?
  • Has the lease been terminated / tenant vacated?
  • Months remaining on the lease term at termination
  • Monthly rent
  • Does the lease have an acceleration clause?
  • Has the landlord already re-let the space?
  • If re-let, new rent received over the overlapping period
