How It Works
Set ETF domicile (US or Ireland), distribution type, dividend yield, total return, tax residency, investment years, and principal. Example: 2% dividend yield, 15% withholding, 30 year horizon, $100,000 principal. US domicile drag costs roughly 0.30% annually while Ireland accumulating ETF drag nears zero for many treaty residents. European investors holding US listed SPY in a taxable account often underestimate cumulative withholding leakage because the 15 to 30 percent drag applies to dividends every year, not just at purchase or sale. Compare accumulating versus distributing share classes for the same index because distribution policy changes drag even when underlying holdings match. Select domicile and investor country: UCITS ETFs face different withholding on US dividends inside the fund wrapper. Select investor tax residency and fund domicile pair before comparing accumulating versus distributing share classes.
