What is Rental Index Calculator?

The Rental Index Calculator serves as a key indicator in real estate, reflecting the fluctuation in rental prices over time for a specific location or property type. It enables property owners, tenants, and investors to grasp the trends and changes in rental values, facilitating informed decisions in the dynamic rental market.

The Formula for Calculating Adjusted Rent with Rental Index Calculator

The formula to calculate Adjusted Rent (\(AR\)) based on the Rental Index is:

\[ AR = \frac{BR \times (CI - BI)}{BI} \]


  • \(AR\): Adjusted Rent
  • \(BR\): Base Rent (Initial Rent Amount)
  • \(CI\): Current Index (Rental Index at the Time of Adjustment)
  • \(BI\): Base Index (Rental Index at the Time of Establishing Base Rent)

Example: Suppose the base rent is $1200, the current index is 150, and the base index is 120. Calculate the Adjusted Rent.


Using the Rental Index Calculator formula:

\[ AR = \frac{1200 \times (150 - 120)}{120} = $300 \]

Therefore, the Adjusted Rent for this example is $300.
