Formula and Assumptions

The cost of living adjustment is calculated using the following formula:

Where:

• Current Amount is the initial value you're adjusting
• Adjustment Rate is the percentage increase (entered as decimal, e.g., 0.035 for 3.5%)
• Years is the number of years for the adjustment

This formula assumes:

• The adjustment is applied annually to the current amount
• The adjustment rate remains constant over the period
• No other factors affect the adjustment

Worked Examples

Example 1: Salary Adjustment

Current salary: $50,000
Annual adjustment: 3.5%
Years: 5

Calculation: $50,000 × (1 + 0.035)^5 = $50,000 × 1.1910 = $59,550

After 5 years with 3.5% annual adjustments, your salary would grow to $59,550.

Example 2: Rent Increase

Current rent: $1,200/month
Annual adjustment: $100
Years: 3

Calculation: $1,200 + ($100 × 3) = $1,500

After 3 years with $100 annual rent increases, your monthly rent would be $1,500.
