"Bad Idea" was written by Grande, Peter Svensson, Savan Kotecha, and its producers Max Martin and Ilya Salmanzadeh. The recording took place in two studios: MXM Studios in Los Angeles, California, and the Wolf Cousins Studios located in Stockholm, Sweden. According to Kotecha, during the development of Thank U, Next, they tried to do different things that Grande had not done before. Following this idea, he wanted to create a song with a melody inspired by British band The Police combined with a trap beat. Svensson, a former member of band the Cardigans, helped with the phrasing of the second line and created the guitar riff of the beginning of the track alongside Ilya. Later, Kotecha, Grande and Martin fixed the melodies. Ilya added the instrumental outro, which the singer decided to extend.
Mattias Johansson, who worked with the singer on her Dangerous Woman album, played the violin. Martin and Salmanzadeh programmed the track and played the guitar, bass, drums and keyboards. Both also were, alongside Mattias Bylund, part of the string section. Grande produced the vocals, with David Bukovinsky playing the cello and Bylund the strings. Sam Holland engineered the song with the help of Cory Byce and Jeremy Lertola. Serban Ghenea mixed it with assistance of John Hanes at MixStar Studios in Virginia Beach, Virginia. Randy Merrill mastered it at Sterling Sound Studios in New York City.
