Upon release, the album was met with generally positive reviews from music critics and debuted at number 29 on the Billboard 200, with first-week sales of 50,000 copies in the United States.

[9] It was later announced the song "Love Sosa" would be featured on the video game Grand Theft Auto V.[10] "Hate Bein' Sober" was released as the album's third single on December 13, 2012.

[15] Randall Roberts of the Los Angeles Times gave the album two and a half stars out of four, saying "Landing a week before the big day, the 17-year-old Chicago thug offers infectious odes to nihilism and tirades against haters that are as simple-minded and catchy as they are brutal.

[20] Greg Kot of the Chicago Tribune gave the album two stars out of four, saying "Finally Rich" owes plenty to the menacing inner-city narratives of Jeezy, Waka Flocka and Gucci Mane.

Deliberately defining a song titled Laughin' to the Bank by its absence of any mirth is entirely in character for Keef, who wears his perpetual screwface like a badge of pride across Finally Rich and never once lets light in.

"[26] Jesse Fairfax of HipHopDX gave the album three out of five stars, saying "A fair assessment can see his dangerous character as a product of his environment rather than simple glorification of wrongdoing, with Finally Rich creating entertainment out of hopelessness.

"[24] Anupa Mistry of Now gave the album two out of five stars, saying "Maybe the lasting value of Finally Rich won't be found in questioning its moral content (less a glorification of violence and poverty than a lament), but in parsing how we’ve reacted to it, and the differing socio-economic realities that make his music resonant for one demographic and a voyeuristic pleasure for another.

"[23] David Jeffries of AllMusic gave the album two and a half stars out of five, saying "In the end, it's raw, irresponsible, unforgiving, and often infectious, but the controversial Finally Rich isn't a step forward on any counts.

"[17] Kitty Empire of The Observer gave the album three out of five stars, saying "His major label debut, Finally Rich compiles a slew of his tracks that have done the rounds, with a handful of new songs.
