How CPI Escalator calculates rent adjustments
It turns CPI-based lease language into clear, defensible rent adjustments using official data from the U.S. Bureau of Labor Statistics, and generates a print-ready notice that is consistent, auditable, and hard to mess up.
Step by step
Enter lease and tenant details
Prior rent, tenant and property address, effective date, and the CPI clause inputs: base month and year, comparison month and year, and any cap or floor language such as "not to exceed 5%".
Select the CPI series and method
Choose the CPI series, for example CPI-U, and let CPI Escalator pull official index values for the selected periods. You can also run manual scenarios by entering index values directly.
CPI change and adjustment rules are applied
It computes the percent change between base and comparison periods, then applies any lease caps or floors to produce the allowed adjustment and the new rent amount.
Set delivery method and notice formatting
Choose the delivery method, for example email versus printed notice, so the notice language stays consistent. A soft one-page guard keeps the letter to a clean, print-friendly format.
Generate a print-ready notice with safeguards
The live preview updates as you edit. Validation warnings call out missing fields before print or send. Workspace users can save defaults such as contact block and letterhead to cut re-entry across letters.
Built for
Property managers, landlords, HOA and COA administrators, asset managers, and internal accounting teams. Works for residential, commercial, industrial, mixed-use, and land scenarios where CPI clauses apply.
Keep in mind
It does not replace legal review. Where a lease has ambiguous or unusual CPI clauses, confirm methodology with counsel or ownership before sending. The tool focuses on repeatable math and consistent output.
