What this retirement calculator does
This calculator estimates the investment portfolio you may have at retirement and compares it with a target based on the annual income your investments need to provide. It considers current savings, monthly contributions, expected return, inflation, retirement age, other income and a planning withdrawal rate.
The result is a framework for exploring readiness. It is not a full retirement plan because taxes, healthcare, housing, pensions, investment volatility and changes in spending require more detailed analysis.
How the required fund is estimated
The annual income gap equals desired retirement income minus other dependable income. Dividing that gap by the withdrawal rate produces a target fund. For example, an income gap of S$40,000 at 4% implies a S$1 million portfolio.
The current portfolio and monthly contributions are projected to retirement using a real return after inflation. This keeps the projected fund and desired income in today’s purchasing power.
How to interpret the funding ratio
The funding ratio compares the projected portfolio with the required fund. A result above 100% means the smooth projection exceeds the target. A result below 100% indicates a gap under the assumptions entered.
Review the monthly contribution required to close a gap and test a later retirement age, lower spending or a more cautious withdrawal rate. A plan that only succeeds with an optimistic return deserves further stress testing.
Common retirement planning mistakes
- Ignoring inflation over a retirement that may last decades.
- Underestimating healthcare, insurance and housing maintenance.
- Treating pensions or rental income as guaranteed when they are uncertain.
- Using one average return without considering poor early-retirement markets.
- Planning only to average life expectancy rather than allowing a longevity margin.
Frequently asked questions
How much money do I need to retire?
It depends mainly on the income gap your investments must fund and the withdrawal rate used.
Why use a withdrawal rate?
It converts an annual portfolio-funded income need into a target amount.
Does the calculator include inflation?
Yes. It converts the expected return into a real return so results remain in today’s money.
What counts as other retirement income?
Potential examples include CPF payouts, pensions or dependable annuity income.
How should I choose a planning age?
Use an age that provides a longevity margin rather than relying only on average life expectancy.
Does it model spending declining in later retirement?
No. It uses a constant real annual income target.
Are taxes and fees included?
No. Consider reducing the return assumption or increasing the target.
What if I have a shortfall?
Test higher contributions, later retirement, lower spending or a different withdrawal rate.
