 The group has sold over 7 million units in the United States alone, with three platinum records, two gold records, two multi-platinum singles, two platinum singles, and five gold singles as designated by the RIAA.
 The band signed with Hollywood Records in 2002 following the success of their independently-released eponymous EP, and began recording their first full-length major-label debut "Saturate" shortly thereafter.
 The record peaked at No. 2 on the "Billboard" Heatseekers chart and No. 136 on the "Billboard" 200 chart.
 It was certified gold more than thirteen years later.
 The band's sophomore effort, "We Are Not Alone", released in 2004, peaked at No. 20 on the "Billboard" 200, and was later certified platinum in the United States and gold in New Zealand.
 Breaking Benjamin's third studio album "Phobia" was released in 2006 and reached No. 2 on the "Billboard" 200 chart, No. 1 on the Digital Albums chart, No. 1 on the Rock Albums chart, and was certified platinum nearly three years after its release.
 Breaking Benjamin released their fourth record in late 2009 titled "Dear Agony", reaching No. 1 on the Hard Rock Albums and Modern Rock/Alternative Albums charts, No. 2 on the Rock Albums and Digital Albums charts, and No. 4 on the "Billboard" 200.
 The record was certified gold three months after its release and was eventually certified platinum seven years later.
