Formula Used

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

Cost of Living Adjustment Formula

Adjusted Amount = Current Amount × (1 + Inflation Rate/100)^Years

Where:

Current Amount = Your current salary, pension, or benefit value
Inflation Rate = The percentage increase in prices over the period
Years = The number of years for the adjustment

This formula assumes a compound adjustment where each year's inflation rate is applied to the previous year's adjusted amount.

Worked Examples

Example 1: Salary Adjustment

Current salary: $50,000
Inflation rate: 3%
Years: 5

Adjusted Amount = $50,000 × (1 + 0.03)⁵ ≈ $50,000 × 1.159274 ≈ $57,963.70

After 5 years with a 3% annual inflation rate, your salary would need to increase to $57,963.70 to maintain the same purchasing power.

Example 2: Pension Adjustment

Current pension: £25,000
Inflation rate: 2.5%
Years: 10

Adjusted Amount = £25,000 × (1 + 0.025)¹⁰ ≈ £25,000 × 1.282051 ≈ £32,051.28

After 10 years with a 2.5% annual inflation rate, your pension would need to increase to £32,051.28 to maintain the same purchasing power.

Note

These examples assume a constant inflation rate. In reality, inflation rates can vary significantly from year to year.
