What is an SWP?

A systematic withdrawal plan turns a lump sum into a monthly income: you sell a fixed amount every month while the rest stays invested. In most countries the hard part is working out the tax on each withdrawal. In Singapore, for individual investors, there isn't any.

No capital gains tax — what that actually means

Because Singapore doesn't tax individuals' capital gains, every dollar you withdraw is yours: gross equals net, the take-home column in the table below simply matches what you sold. Compare that with the US, UK, Australia or Canada pages on this site and you'll see how unusual that is.

The standing caveat: IRAS can tax profits as income if your pattern amounts to trading (constant turnover, short holds, leverage). Selling a fixed slice of a long-held portfolio each month is investing, not trading.

So the only question is sustainability

With tax out of the picture, everything rides on the balance between your withdrawal rate and your return. Green bars show your projected year-end balance; they turn red in the year the portfolio runs out. Setting the annual increase equal to inflation keeps your income's buying power level — at Singapore's low long-run inflation, that costs less than you'd think.

Frequently asked questions

Are SWP withdrawals really tax-free in Singapore?

For an individual investor selling long-held investments, yes — Singapore levies no capital gains tax, so your gross withdrawal is your take-home. The exception is if IRAS classifies your activity as trading, which a monthly withdrawal plan from a long-term portfolio is not.

What withdrawal rate is sustainable?

Mathematically, a withdrawal rate below your expected return lets the balance keep growing forever; above it, the corpus eventually depletes. Try your numbers: the chart shows the exact year the bars turn red, and small changes to the monthly amount move it a lot.

Can I run an SWP from CPF?

CPF has its own payout mechanisms (like CPF LIFE) under its own rules — it isn't modelled here. This calculator is for an investment portfolio held with a broker in cash.

Why is there still a cost-basis field?

Purely informational in Singapore — since gains aren't taxed, the split doesn't change your take-home. It's kept so the projection table can show how much of your withdrawals are growth versus your own contributions.
