Small steps add up. Here’s the next one.
What This Estimate Assumes
Rough estimate. Option A is a US-domiciled fund: US dividends lose 30%, because Singapore has no income tax treaty with the US. Option B is an Ireland-domiciled UCITS fund that holds US shares and pays 15% on the dividends it receives under the US–Ireland treaty. Each year the value grows by your expected price growth plus dividends after tax, then the expense ratio comes off: the tool works year by year, while the Investment Fees Impact tool works month by month, so their figures are not directly comparable. Dividends are reinvested. Ignores currency moves, bid-ask spreads, trading costs, tracking differences, estate tax and any other tax. Whether a fund qualifies for the treaty rate depends on the fund.

Before You Use This Number
Why Do US-Domiciled Funds Lose 30% Of Dividends?
The US takes 30% of US dividends paid to foreign investors unless a tax treaty lowers it. Singapore has no income tax treaty with the US, so a Singapore investor holding a US-listed fund loses 30%.
Why Do Ireland-Domiciled Funds Lose Only 15%?
The US–Ireland tax treaty sets 15% on portfolio dividends. An Ireland-domiciled fund that holds US shares can usually claim it on the dividends it receives. This depends on the fund, so check its documents.
Does This Pick A Fund For Me?
No. It compares two options using the numbers you enter. Spreads, fund size, tracking and how you buy also matter.
