How CPI Escalator calculates rent adjustments

Step-by-step flow

1. 1. Enter lease and tenant details. Provide prior rent, tenant/property address, effective date, and the CPI clause inputs (base month/year, comparison month/year, and any cap/floor language such as “not to exceed 5%”).
2. 2. 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.
3. 3. CPI change and adjustment rules are applied. CPI Escalator computes the percent change between base and comparison periods, then applies any lease caps/floors to produce the allowed adjustment and the new rent amount.
4. 4. Delivery method + notice formatting are set. Choose the delivery method (for example, Email vs Printed Notice) so the notice language stays consistent. A soft one-page guard helps keep the letter to a clean, print-friendly format.
5. 5. Generate a print-ready notice with safeguards. The live preview updates as you edit. Optional validation warnings call out missing fields before print/send. Workspace users can also save defaults (contact block and letterhead) to reduce re-entry across multiple letters.

When to use it

CPI Escalator is intended for professional users who need a fast, consistent way to calculate CPI-based rent adjustments and generate notices with fewer errors: property managers, landlords, HOA/COA administrators, asset managers, and internal accounting teams. It works for residential, commercial, industrial, mixed-use, and land/lot scenarios where CPI clauses are used.

It does not replace legal review or formal interpretation of lease language. Where leases contain ambiguous or unusual CPI clauses, confirm methodology with counsel or ownership before sending notices. CPI Escalator focuses on repeatability: clear math, consistent outputs, and guardrails (like warnings and one-page print-fit) that help teams avoid accidental omissions.
