18 Months received generally mixed reviews from music critics. At Metacritic, which assigns a normalised rating out of 100 to reviews from mainstream publications, the album received an average score of 57, based on 17 reviews.{{cite web |url=https://www.metacritic.com/music/18-months/calvin-harris |title=18 Months by Calvin Harris Reviews and Tracks |website=Metacritic |access-date=17 November 2012}} Fraser McAlpine of BBC Music hailed the album as a "collection almost exclusively in the key of triumph", as well as "a portfolio of win for Calvin, an annual report where the graph is almost all peaks and the troughs are so far down they're practically invisible."{{cite web |last=McAlpine |first=Fraser |url=https://www.bbc.co.uk/music/reviews/ndj9 |title=Review of Calvin Harris – 18 Months |publisher=BBC Music |date=29 October 2012 |access-date=4 November 2012}} Arwa Haider of Metro commented that "18 Months could be a capsule collection of smash singles, yet it also works brilliantly as an album. That's partly because these are never faceless anthems; its singers [...] are well judged and rise to the songs, while the catchy hooks are lovingly arranged".{{cite web |last=Haider |first=Arwa |url=https://metro.co.uk/2012/11/01/calvin-harris-18-months-album-review-611840/ |title=Calvin Harris's 18 Months is a capsule collection of smash singles |work=Metro |date=2 November 2012 |access-date=5 December 2014}} AllMusic's Tim Sendra wrote that the album "shows Harris to be a solid producer with an easily identifiable sound."{{cite web |last=Sendra |first=Tim |url=https://www.allmusic.com/album/18-months-mw0002306017 |title=18 Months – Calvin Harris |website=AllMusic |access-date=4 November 2012}} Mikael Wood of the Los Angeles Times noted that despite the variety of male collaborators, the album "only deepens the impression that Harris is best when linked with a lady; his skills in that area are several times more developed than they are anywhere else."{{cite web |last=Wood |first=Mikael |url=https://www.latimes.com/entertainment/music/la-xpm-2012-oct-30-la-et-ms-album-review-calvin-harris-20121030-story.html |title=Review: Calvin Harris performs solo but should maybe hunt up a woman collaborator |work=Los Angeles Times |date=30 October 2012 |access-date=18 June 2013}} The Independent{{'}}s Andy Gill was unimpressed by Ellie Goulding's performance on "I Need Your Love", but complimented Welch on "Sweet Nothing", and cited Harris's collaboration with Nicky Romero on "Iron" as the album's "killer cut".{{cite web |last=Gill |first=Andy |url=https://www.independent.co.uk/arts-entertainment/music/reviews/album-calvin-harris-18-months-fly-eye-8226827.html |archive-url=https://ghostarchive.org/archive/20220501/https://www.independent.co.uk/arts-entertainment/music/reviews/album-calvin-harris-18-months-fly-eye-8226827.html |archive-date=1 May 2022 |url-access=subscription |url-status=live |title=Album: Calvin Harris, 18 Months (Fly Eye) |work=The Independent |date=27 October 2012 |access-date=28 October 2012}}{{cbignore}}

Emily Mackay of NME opined that "[t]he best collaborations stand alone, but the rest demands small hours and sweat to animate it", stating the album "feels more like a deserved victory lap than a forward step or a new instalment, but apart from his sole vocal on 'Feel So Close', the victor seems oddly absent."{{cite web |last=Mackay |first=Emily |url=http://www.nme.com/reviews/calvin-harris/13813 |title=Calvin Harris – '18 Months' |work=NME |date=26 October 2012 |access-date=4 November 2012 |archive-url=https://web.archive.org/web/20130513010543/http://www.nme.com/reviews/calvin-harris/13813 |archive-date=13 May 2013}} Killian Fox of The Observer remarked, "Nothing else on 18 Months matches up to the blockbusting collaborations with Kelis, Florence Welch and Rihanna", concluding that "Harris's production has become increasingly homogenised and, despite the array of vocalists, everything here risks sounding the same."{{cite web |last=Fox |first=Killian |url=https://www.theguardian.com/music/2012/oct/28/calvin-harris-18-months-review |title=Calvin Harris: 18 Months – review |work=The Observer |date=28 October 2012 |access-date=28 October 2012}} At Entertainment Weekly, Melissa Maerz complimented songs like "We Found Love" and "I Need Your Love", but found that the album does not offer "many surprises".{{cite magazine |last=Maerz |first=Melissa |url=https://ew.com/article/2012/10/26/18-months-review-calvin-harris/ |title=18 Months |magazine=Entertainment Weekly |date=24 October 2012 |access-date=6 August 2015}} Despite referring to Harris as a "brilliant pop craftsman", The A.V.

But for all the pop divas he has roped in, there's a veneer of cynical, laddy EDM, resulting in the kind of tracks Skrillex might come up with on an Ayia Napa booze cruise."{{cite web |last=Nicholson |first=Rebecca |url=https://www.theguardian.com/music/2012/oct/25/calvin-harris-18-months-review |title=Calvin Harris: 18 Months – review |work=The Guardian |date=25 October 2012 |access-date=25 October 2012}}
