How it's calculated

  • Escalation applies to base rent once per lease year. NNN is held flat (in practice it changes with actual costs).
  • NNN is still charged during free base-rent months, which is typical but not universal — check your lease.
  • TI allowance is subtracted from total cost to show an effective rate.
  • Defaults are illustrative, not market rates.
Estimates only. Results depend on the numbers you enter and are not financial, tax or legal advice.
