How to use this rent escalation calculator

  1. Enter your starting annual base rent (the Year 1 figure before any increase).
  2. Set the annual escalation rate as a percentage (e.g., 3% for a typical fixed bump).
  3. Enter the lease term in years to see each year's annual and monthly rent, the total over the term, and how much the escalations add versus a flat lease.

The first increase applies in Year 2 — Year 1 is charged at your starting rate. For the most reliable projection, copy the exact escalation language and base rent from your lease before modeling it here.

Rent escalation checklist

  • Type: Is the bump a fixed percentage, a CPI index, or a stepped dollar schedule?
  • Compounding: Does each increase build on the prior year's rent, or on the original base?
  • Caps & floors: For CPI leases, is there a ceiling (and possibly a minimum) on the annual change?
  • Scope: Does the escalation apply to base rent only, or also to operating-expense and tax pass-throughs?
  • Renewals: How is rent reset at option/renewal terms — fair market value, a fixed step, or continued escalation?
