In the United Kingdom, it reached forty-seven, and was on the chart for three consecutive weeks. It reached fifty-one on the Canadian Hot 100.

The song performed moderately in international markets. However, it did not match the peaks of its predecessor ' Naturally' on those charts, where the latter peaked at one and twelve. It also appeared on the Billboard charts the Hot Dance Club Play and Pop Songs charts at two and thirty-four. Propelled by a debut at number fifteen on the US Hot Digital Songs chart, 'Round & Round' debuted at number twenty-four on the Billboard Hot 100, becoming the band's second consecutive top thirty single in the United States. Overall, Copsey complimented Gomez for 'avoiding the predictable Hilary/Miley teen-rawk route' and recommended she stay under the Disney umbrella to 'perfect her craft further'. Becky Bain of Idolator said the song had an 'infectious tune', and said 'might actually be the song to get the non-Disney-centric demographic interested in Selena's tunes.' Although commenting that the 'glossy electro-pop rock' of the song showed a sophisticated side of Gomez, and the lyrics showed emotional growth, Robert Cospey of Digital Spy said the good work was squandered by the 'rusty' chorus. Tim Sendra of Allmusic said that the song was 'well sung' and noted it as one of the top tracks on the album.
