1. What is CPI Rent Adjustment?

The CPI (Consumer Price Index) Rent Adjustment is a method to adjust rental prices based on changes in the cost of living. It ensures that rental income maintains its purchasing power over time by accounting for inflation.

2. How Does the Calculator Work?

The calculator uses the CPI adjustment formula:

Where:

• Original Rent — The initial rental amount in dollars
• CPI_current — Current Consumer Price Index value
• CPI_base — CPI value at the time of the original rent

Explanation: The formula calculates how much the original rent should be adjusted to maintain equivalent purchasing power given changes in the cost of living.

3. Importance of CPI Adjustment

Details: CPI adjustments protect both landlords and tenants by ensuring fair rent increases that reflect actual changes in living costs, preventing arbitrary price hikes while maintaining property value.

4. Using the Calculator

Tips: Enter the original rent amount in dollars, current CPI index value, and base CPI index value (from when original rent was set). All values must be positive numbers.
