How to Use This Calculator
  1. Enter Square Feet and Starting Base Rent per SF per year.
  2. Set Fixed Annual Increase % — the escalation clause in the lease (typically 2–3%).
  3. Enter Lease Term in years and Estimated CPI for comparison against fixed escalations.
  4. Review Total Lease Cost — the sum of all rent payments over the full term.
  5. Check Final Year Rent to understand your rent obligation at lease expiration.
  6. Compare Fixed vs. CPI Difference to evaluate whether a fixed escalation or CPI-linked clause is more favorable.
