Formula and Assumptions

Formula

Future Expenses = Current Expenses × (1 + Inflation Rate)^Years

Where:

Current Expenses = Your current monthly expenses
Inflation Rate = Expected annual increase in prices (as a decimal)
Years = Number of years into the future you want to project

Assumptions

This calculator assumes:

Constant annual inflation rate over the projection period
No changes in your personal expenses beyond price increases
Inflation rates are based on historical Australian data

Worked Example

Let's say you currently spend $2,500 per month on essential expenses. You expect a 3% annual inflation rate and want to project your expenses 5 years into the future.

Using the formula:

Future Expenses = $2,500 × (1 + 0.03)^5

Future Expenses = $2,500 × 1.159274

Future Expenses ≈ $2,900.69

After 5 years, you can expect to spend approximately $2,900.69 per month on essential expenses, accounting for 3% annual inflation.
