Compare VWRA, VALL, CSPX, US-listed ETFs and SGX-listed Xtrackers UCITS ETFs by dividend withholding tax, expense ratios, FX and bid-ask spreads, and broker fees.
When you buy a US-domiciled ETF like VOO from Singapore, every dividend it pays you is withheld at 30% before it ever reaches your account because Singapore has no tax treaty with the United States. An Irish-domiciled UCITS fund like CSPX holds the same S&P 500 stocks, but thanks to the US-Ireland treaty it loses only 15% at fund level, and Ireland withholds nothing on what it passes to you. On a 1.3% dividend yield, that difference compounds into a meaningfully larger balance over decades.
For investors who want to “VWRA and chill”, “SPYL and chill”, or simply set and forget a monthly ETF plan, domicile and tax drag still matter. Two funds can hold similar stocks while leaving you with different after-tax results.
The calculator runs the same monthly investment plan down four paths: a US-domiciled fund (30% dividend withholding), an Irish-domiciled fund bought on LSE in USD (15%), the same kind of Irish fund bought on SGX in SGD (15%, no FX conversion), and a frictionless zero-fee baseline. Each month it invests your contribution net of FX spread and broker commission, grows the balance at your expected return split into price growth and dividends, reinvests dividends net of withholding tax, and deducts the fund’s TER plus any platform fee. The withholding gap is the headline number: how much more the Irish route leaves you with, after netting off any TER difference between the two funds.
Withholding tax is the biggest hidden cost for most Singapore index investors, but it is not the only one. A 0.3% FX spread on every SGD→USD conversion, a $2 commission on every monthly buy, and a platform fee of even 0.2% a year each take their own compounding bite. The cost-drag breakdown shows each component separately so you can see which lever, whether fund domicile, broker choice, or FX, is actually worth optimising.
Four Irish-domiciled Xtrackers ETFs are due to list on SGX on 13 October 2026: XUS (S&P 500, 0.03% TER), XWR (MSCI World, 0.12%), EUS (S&P 500 Equal Weight, 0.15%) and XND (Nasdaq 100, 0.20%). They carry the same 15% withholding tax as CSPX or VWRA, trade in SGD during Singapore hours, and are held through CDP in your own name.
SGD-quoted is not the same as SGD-hedged. These funds still hold US dollar assets, so if the US dollar falls against the Singapore dollar, XUS falls with it exactly as CSPX would. What SGD quoting saves you is the SGD→USD conversion on each buy. What it can cost you is a wider bid-ask spread, because SGX trading volume is thinner than LSE. Whether the SGX route wins depends on your monthly amount, your broker’s FX rate and the spread you actually see, which is why the calculator lets you set all three. Until the funds have traded for a few weeks, treat the default 0.2% spread as a guess.
Compare like with like. XWR tracks developed markets only, while VWRA and Vanguard’s newer VALL (0.07% TER, launched August 2026) are all-world funds that include emerging markets, and VALL adds small caps too.
Non-US investors holding more than US$60,000 of US-situs assets, which includes US-domiciled ETFs like VOO and VT, can face US estate tax of up to 40% on death. Irish funds are not US-situs assets, whether you buy them on LSE or SGX. Some investors look at setting up a private company to hold their brokerage account for this reason, but for most portfolio sizes switching to Irish-domiciled funds solves the problem more simply and cheaply.

Singapore has no tax treaty with the United States, so dividends paid by US-domiciled funds to Singapore residents are withheld at the full 30% rate. Irish-domiciled UCITS funds holding the same US stocks suffer only the 15% US-Ireland treaty rate at fund level, and Ireland does not withhold tax on distributions to Singapore investors.
Usually, but not automatically. Irish UCITS funds often have slightly higher expense ratios than their US-listed equivalents, so for very low dividend yields the TER difference can matter. This calculator nets the two effects so you can compare on your actual numbers.
No. They are quoted and traded in SGD, but they hold the same USD-denominated stocks as the LSE versions, so your currency exposure is unchanged. What SGD quoting removes is the SGD→USD conversion on each buy. What it may add is a wider bid-ask spread, because SGX volume is thinner than LSE. The calculator lets you set that spread and compare it against the FX spread you pay to buy on LSE.
VWRA (0.14% TER) and VALL (0.07% TER, launched August 2026) both track all-world indices including emerging markets, and VALL adds small caps. XWR (0.12%) tracks MSCI World, which is developed markets only, so it is not a like-for-like substitute for VWRA. Pick the index you actually want first, then use the calculator to compare the cost of each route to it.
Usually not. US-situs assets above US$60,000, including US-domiciled ETFs like VOO or VT, can be exposed to US estate tax of up to 40% for non-resident aliens. Irish-domiciled funds, whether bought on LSE or SGX, are not US-situs assets, so switching domicile solves the problem for most portfolio sizes without the cost of running a holding company.
