Singapore’s robo-advisors are cheap, until you do the multiplication
The pitch from Singapore’s robo-advisors is hard to argue with on the surface. For somewhere around 0.5 to 0.8 percent a year, a platform like StashAway, Endowus, or Syfe handles your asset allocation, rebalancing, and reinvestment with no minimum effort from you. Compared with a private banker, that is a bargain. The problem is the comparison most investors should actually be running: not robo against private bank, but robo against simply buying a broad-market ETF yourself for under 0.2 percent all-in. That gap of half a percentage point sounds trivial and is anything but, because it is levied every single year on your entire balance, gains included. This tool exists to turn that abstract fraction into the dollar figure it really represents.
To be fair to the robos, the convenience and the discipline they enforce are worth something, and for an investor who would otherwise not invest at all, or would panic-sell in a downturn, the fee can be money well spent. But you should at least know its size before you decide it is worth it.
$100,000 left to compound for 25 years
Take $100,000 invested for 25 years at a 7 percent gross return, comparing a 0.7 percent robo fee against a 0.15 percent do-it-yourself ETF cost. The robo portfolio compounds at 6.3 percent net, the DIY portfolio at 6.85 percent, off the same starting capital and the same market.
A 0.55 percentage point fee gap quietly removes $63,430, more than half of the original $100,000 you started with. That is the part people refuse to believe. The gap is not 14 percent (0.55 times 25). It is far larger, because every dollar the fee skims is a dollar that never gets to compound for you across the remaining years. The lines below show the two balances pulling apart over the quarter century.
The fee is not the only number that moves
Two things make the dollar gap bigger than your intuition expects. The first is the gross return: the higher it is, the more the fee skims, because the percentage is taken from a faster-growing base. At a 4 percent return the lost figure is far smaller than at 9 percent, even though the fee percentage is identical. The second is time. The fee drag compounds, so doubling the horizon far more than doubles the loss. A fee that costs you a modest sum over 10 years becomes punishing over 30. If you are a young investor with decades ahead, the fee decision is one of the highest-stakes choices you will make, precisely because you have the most years for the drag to compound.
A practical note specific to Singapore: do not stop at the robo’s headline management fee. The underlying ETFs inside your robo portfolio carry their own expense ratios, so your true all-in cost is the platform fee plus those fund costs. Some platforms quote one and stay quiet about the other. And there is a tax angle worth knowing: a portfolio built on US-domiciled ETFs suffers a 30 percent withholding tax on dividends for Singapore investors, whereas Ireland-domiciled equivalents cut that to 15 percent. That hidden leakage can dwarf a small fee difference, so weigh fund domicile alongside the headline percentage when you run the numbers here.
Is a robo-advisor ever the cheaper choice overall?
Rarely on pure cost, but sometimes on net outcome. If a robo stops you sitting in cash for years out of indecision, or stops you selling at the bottom of a crash, the behavioural value can exceed the fee many times over. The fee only looks like pure waste when you are confident you would otherwise build and hold a low-cost ETF portfolio with the same discipline. Be honest with yourself about that, because the spreadsheet assumes a discipline many investors do not actually have.
Do these fees affect my income tax in Singapore?
No. Investment management fees are not tax-deductible for an individual investor in Singapore, and since there is no capital gains tax here, your investment growth is not taxed either way. The fee is simply a direct reduction of your returns, with no offsetting tax relief, which is another reason to keep it as low as you reasonably can. Local dividends you receive are also not taxed in your hands under the one-tier system, so the fee, not tax, is the main controllable drag on a domestic portfolio.
