About This Retirement Calculator
Planning for retirement can feel overwhelming, but breaking it down into clear numbers makes it manageable. Our retirement calculator is designed to help you visualise your financial future by estimating how your current savings and monthly contributions will grow over time through the power of compound interest.
Whether you are just starting your career and want to see the long-term impact of small monthly contributions, or you are nearing retirement and need to verify if your nest egg will support your desired lifestyle, this tool provides the clarity you need to make informed financial decisions.
Three modes cover every scenario: Savings Projection for a full year-by-year growth chart, How Much? to calculate the exact portfolio size your retirement income requires, and Am I On Track? to compare your projected balance directly against your goal.
The calculator now also shows an inflation-adjusted estimate in projection modes. This helps separate the future account balance from its likely buying power, which is especially important when your retirement date is decades away.
How to Use This Calculator
- 1
Project your savings growth
Use the Savings Projection tab. Enter your current age, planned retirement age, existing savings, and monthly contribution. The calculator uses compound interest to estimate your total balance at retirement, broken down into contributions and investment growth.
- 2
Calculate how much you need
Switch to the How Much? tab. Enter the annual income you want in retirement and your planned safe withdrawal rate - commonly 4%. The calculator tells you the exact portfolio size required to sustain that income without running out of money.
- 3
Check if you are on track
Use the Am I On Track? tab. Enter the same savings details plus a retirement goal. The calculator compares your projected balance against your target, showing whether you have a surplus or a shortfall.
- 4
Adjust your plan
If you are behind, experiment with increasing your monthly contribution, delaying your retirement age, changing the inflation assumption, or targeting a higher return. Small changes compound significantly over long timeframes, and inflation can change what your final balance is really worth.
