Here is the "after tax" returns directly from Vanguard website. Tax cost ratio depends upon investor's own tax brackets. I would also ignore all third party websites, instead it is better directly go to fund websites and read prospectus. Even M* does not have right information about qualified dividends. Vanguard has the advantage because same fund can be mutual fund or ETF. That way they can tax manage efficiently. No other fund (as far as i know) has similar arrangement.
