In Taiwan, the album sold more than 100,000 copies, becoming the country's 10th best-selling album of the year 2005, as well as the year's fourth best-selling album by a female artist. A Perfect Day was ultimately Sun's last original studio album to be released under Warner Music Group, since she left the company the following year in 2006 to go to Capital Music Taiwan.
