Quick Answer
Starting later loses the longest-growing years, not just the payments you skip. S$500 a month at 6% for 30 years could grow to about S$502,258. Starting 5 years later could leave about S$155,761 less, although you would put in only S$30,000 less.
The Useful Number: S$500 a month at 6% for 30 years could grow to about S$502,258. Starting 5 years later could leave you with about S$155,761 less, though you would put in only S$30,000 less.
Why Does Starting Later Cost So Much?
Money invested early has the most years to earn returns, and then returns on those returns. When you delay, you lose the payments you skip and, more importantly, the longest-growing years of growth.
What Does A 5-Year Delay Cost Over 30 Years?
- Start now: S$500 a month for 30 years at 6%: About S$502,258
- Start in 5 years: S$500 a month for 25 years: About S$346,497
- Cost of waiting: About S$155,761
- Money you did not put in: S$30,000
- Monthly amount to catch up: About S$725
The return is an assumption, not a forecast. At a lower return the gap shrinks; at 0% it is just the S$30,000 you did not put in.

What Does The Estimate Leave Out?
