Before evaluating any investment, a Singapore investor should be clear about the opportunity cost. CPF Ordinary Account funds earn a guaranteed 2.5 percent per year, with an additional 1 percent on the first S$20,000 held in OA for members below age 55. The Special Account earns 4 percent, also with the extra 1 percent bonus tier on the first S$40,000 combined across SA and OA. These are risk-free, government-backed rates. Any investment outside CPF needs to beat these thresholds after fees and taxes to be worth the additional risk. For long-term equity investing, the historical premium over the CPF rates has been meaningful, but the path is volatile.
Compounding and time
The most powerful variable in this calculator is time, not the return rate. Starting with S$50,000 and adding S$1,000 per month at 7 percent for 20 years produces a meaningfully larger result than starting 5 years later with a higher contribution. The reason is that early capital compounds for a longer runway. A 7 percent return doubles money in roughly 10 years under the rule of 72. The monthly contribution effect is significant too: S$1,000 per month over 20 years is S$240,000 of contributions, but at 7 percent those contributions themselves earn growth, so the ending balance is larger than the sum of contributions plus interest on the initial lump sum.
Singapore tax advantages for investors
Singapore is unusually favourable for long-term investors. There is no capital gains tax, so selling a stock or ETF at a profit produces no tax liability. Dividends from Singapore-resident companies are tax-exempt under the one-tier system. Interest from local bank accounts is exempt. SRS contributions (up to S$15,300 per year for Singapore citizens and PRs) reduce taxable income, and SRS investments grow tax-deferred. These advantages stack: a Singapore investor holding global ETFs through a local broker pays no tax on dividends or gains, accumulates in a low-fee structure, and can top up SRS for additional deferred tax benefit. The comparison figure from this calculator, against which CPF OA and SA are shown, reflects these conditions.
Frequently asked questions
What return rate should I use for a Singapore investment portfolio?
The STI ETF tracking the Straits Times Index has delivered roughly 7 to 9 percent annualised total return including dividends over long periods. Global equity index funds available through Singapore brokers have historically returned around 7 to 10 percent nominally. For a balanced portfolio with bonds, 5 to 7 percent is a common planning assumption. Compare any target return against the guaranteed CPF rates: 2.5 percent for the OA and 4 percent for the SA and MediSave.
Is investment growth taxed in Singapore?
Singapore does not have a capital gains tax, so profits from selling shares, unit trusts, ETFs, or most investment products are not taxed for individuals. Dividends from Singapore-resident companies under the one-tier tax system are tax-exempt in the hands of shareholders. Interest from Singapore bank deposits held by individuals is also tax-exempt under IRAS rules. Foreign-sourced income remitted to Singapore may be taxable in some circumstances depending on the source country and income type.
How does CPF compare to market investing?
CPF accounts offer guaranteed government-backed returns: 2.5 percent on the Ordinary Account and 4 percent on the Special Account, with an extra 1 percent on the first S$60,000 of combined balances. These are risk-free returns. Market investments can deliver higher long-run returns but carry volatility and capital risk. The Retirement Account earns 4 percent. CPF-OA funds can be invested in selected unit trusts, shares, and ETFs under the CPF Investment Scheme, though the guaranteed 2.5 percent is foregone during the invested period.
What investment platforms are available in Singapore?
Singapore investors can access the local market through CDP-linked brokers such as DBS Vickers, UOB Kay Hian, and Lim and Tan. For international markets, Interactive Brokers, Tiger Brokers, and Moomoo are popular among retail investors. Robo-advisors such as StashAway, Endowus, and Syfe offer automated diversified portfolios. Regular savings plans (RSPs) at most banks allow monthly contributions into unit trusts or ETFs from as little as S$100.
