The simplest tax story on this site
Elsewhere, chaining the investing and withdrawal phases matters because of cost basis and capital gains tax. In Singapore there is no capital gains tax for individual investors, so the planner's withdrawal column and take-home column are simply equal — what you sell is what you keep.
That leaves the one question that actually matters: sustainability. Invest monthly for your chosen years, then test whether your target monthly income outlives your horizon or runs the portfolio dry.
Reading the timeline
Bars rise through your RSP years as contributions compound, then the drawdown begins. If your withdrawal rate stays below your return, the bars keep climbing forever; if not, they shrink and turn red in the year the money runs out. Small changes to the monthly amounts move that red year a lot — that's the point of playing with the sliders.

Frequently asked questions
Is the withdrawal phase really untaxed?
For an individual investor selling long-held investments, yes — Singapore levies no capital gains tax, so gross and net withdrawals are identical. The usual caveat: a pattern IRAS would call trading (constant turnover, short holds, leverage) can be taxed as income; a long-term plan like this is the opposite.
What returns should I use for the two phases?
The planner uses one rate for both phases — the STI's ~6% long-run total return by default, editable. Many retirees de-risk before drawdown; if that's you, run it again with a lower rate to see the conservative case.
Where does CPF fit in?
It doesn't — deliberately. CPF balances earn legislated interest under their own rules and pay out through CPF LIFE. Model your market investments here and treat CPF as a separate, stable pillar.
