Hi Anon! Congratulations on embarking on the first step in taking charge of your retirement. In assessing whether you should do a top-up (Voluntary Contribution) into your CPF, here are some notes and factors I would consider: 1. Liquidity The first point I would like to flag here is that any contributions to your CPF are one-way . There is no way to withdraw the monies thereafter; even though you may use them for very specific applications (e.g. OA monies for Housing, MA for Medical treatments, etc). So please consider your current liquidity scenario before even thinking of topping up. 2. Current Cash & Cashflow The next important point to note would be your current cash situation. a. Have you paid off all outstanding loans/non-good debt? The interest charges from your loans (e.g. Credit Card debt / Student Loan) will erode any tax relief / interest yield from CPF. b. Do you need the cash in the immediate future? You need to plan what the immediate milestones are for yourself. You may need the cash to get married (wedding banquets are expensive!), or place a downpayment for a home and also for renovation. Consider how much these costs, factor in your cash inflows, and consider whether you still have enough set aside for topping up into CPF. Having said that, compound interest works wonders for you the earlier you start. So yes, if you have the factors above pinned down, I would definitely recommend topping up into your CPF-SA. (Do kindly note that you are eligible for tax relief only if you top up into your SA ) You may consider topping up less than $7,000 in the first year of your working considering that $7,000 is more than 20% of your total income earned in the first year. Hope this helps!
