The album debuted at number two on the U.S. "Billboard" 200 (behind Mary J. Blige's "Love & Life") with 203,000 copies sold in its first week of release; at the time, it was the highest opening week sales figure for a debut album by a female artist in 2003. Despite a 30% sales drop in its second week, during which it sold 131,000 copies, "Metamorphosis" peaked at number one on the chart for that week. It was certified platinum by the RIAA in three months, and two times platinum by the end of the year. In late November/early December, after Duff had appeared at the Macy's Thanksgiving Day Parade and sneak previews of the film "Cheaper by the Dozen" were held in select cities, "Metamorphosis" returned to the top five on the albums chart with a 132% sales increase over the previous week with 224,000 copies. In the Christmas shopping week, when the album was at number six on the "Billboard" 200, it sold 275,000 copies. It was the eighth best selling album of 2003 according to Nielsen SoundScan, selling 2.6 million copies, and it was certified three times platinum in January 2004. By the September 2004 release of Duff's third album, "Hilary Duff", the album had sold 3.4 million copies in the United States. In August 2005, the release month of Duff's compilation album, "Most Wanted" (in which several "Metamorphosis" tracks are featured), the album re-entered the "Billboard" 200.
