"Too Little Too Late" received positive reviews from music critics.
Entertainment Weekly's Leah Greenblatt cited "Too Little Too Late" as an example of "the best songwriting a major-label budget can buy", while
Billboard identified the song as a track "that can dwell comfortably on both the pop and AC charts", appealing to "listeners of all ages." Similarly,
Amazon.ca's Tammy La Gorce described the song as "addictive but not over-the-top". Another
Billboard critic felt that the song was better than most singles playing on the radio at the time, lauding it as a track that "provides desperately needed balance to a top 40 landscape that is lacking a lot in the way of singable melodies." The writer also praised JoJo's vocal maturity, concluding, "With so many disappointing 'event' singles on the airwaves, radio needs this record." Crowning the song one of the best 10 "Feel-Good Break-Up Songs" in 2007,
Slice contributor Nicolle Weeks joked that nothing is "more humbling than a twerpy 15-year-old who can concisely summarize the way I feel about my stunted relationship". In a more lukewarm review, Evan Sawdey from
PopMatters described the track as "appropriately melodramatic," drawing similarities between it and JoJo's debut single "
Leave (Get Out)" only "without the angry chorus". Sawdey described the song as "something that
Alanis Morissette might have recorded for her last I'm-no-longer-angry-and-therefore-am-content-with-plain-ballads album." Similarly,
People's Oliver Jones wrote that the singer "finds her musical comfort zone" singing "Too Little Too Late". Fraser M. of
BBC Online described the song as "a slab of confident, sophisticated maturo-pop" but felt that the song's production grew repetitive in addition to overwhelming. The critic concluded that the song was a "catchy tune" that "lends itself well to a singalong in the car". In 2007, "Too Little Too Late" earned JoJo a
Boston Music Award for Female Vocalist of the Year. Cunningham won an ASCAP songwriting award for her contributions to the song.
AwesomenessTV's Alexis Joy called the song "terrific" and "our go-to #
Throwback song!". In 2016,
AXS ranked "Too Little Too Late" JoJo's second best song, believing that its popularity eclipsed that of "Leave (Get Out)". In 2016,
GQ's Lauren Larson crowned "Too Little Too Late" the "breakup ballad of the decade." In 2017,
People wrote that "Too Little Too Late" was one of the 14 most "savage" breakup anthems ever recorded. ==Commercial performance==
