One more working year?

Each year you keep working, your salary grows the portfolio by a shrinking percentage, while that year takes a growing share of the active life you have left. Where the two lines cross, another year of work starts costing more than it buys.

Why 70 for both. This is healthy active age, the point up to which you can expect to travel and move about freely, not life expectancy. A Duke-NUS study of older Singaporeans found that at 60, men could expect about 19 more years free of difficulty with daily self-care and women about 18, with no real gender gap. Chinese (19.4 years) and better-educated (23.5 years) Singaporeans did better. Enjoying retirement (long walks, stairs, travel) needs more than self-care and fades earlier, so these ages are deliberately conservative: they count only the years you can make the most of.

For illustration only. This is a simple model, not financial advice; it ignores taxes, inflation, spending needs and CPF.

The model treats every active year as equally valuable and assumes the salary is the only thing you give up by working. With a return above 0%, the portfolio compounds, salary becomes a smaller share faster, and the crossover comes earlier.
