Cost of Living Increase Formula

Percentage Increase = [(Current Expenses - Original Expenses) / Original Expenses] × 100

Absolute Increase = Current Expenses - Original Expenses

This formula measures the change in your expenses relative to your original budget. A positive percentage indicates an increase, while a negative percentage indicates a decrease.

Worked Example

Suppose your original monthly expenses were £2,000 and your current monthly expenses are £2,400. The calculation would be:

Example Calculation

Percentage Increase = [(2,400 - 2,000) / 2,000] × 100 = 20%

Absolute Increase = 2,400 - 2,000 = £400

This means your cost of living has increased by 20% (£400) over the period.

Percentage Increase: This tells you how much your expenses have grown relative to your original budget.
