The "Index of Phir Hera Pheri" is a colloquial term coined by industry experts to describe the benchmark for measuring the success of Bollywood films. It is based on the phenomenal box office performance of Phir Hera Pheri, which grossed approximately ₹65 crores (US$9 million) in India and ₹15 crores (US$2.1 million) overseas, making it one of the highest-grossing films of 2000. The index represents a film's ability to achieve a certain level of commercial success, often considered a threshold for a movie's profitability.
