Fate/Grand Order made over 9 billion yen (approx. US$80 million) in September according to sales prediction data posted by Game-i. The site tracks sales for video games and social game apps.

The amount of money a social game makes per month fluctuates due to the popularity of the events and promotions held in the game, as well as other factors. Fate/Grand Order made 6.4 billion yen (US$56.7 million) in October, but consistently makes around 9 billion yen (US$79.8 million) or more per month. On January, February, June, and July this year, the service made over 10 billion yen (US$88.7 million).

The realization of just how much money Fate/Grand Order generates has been causing a stir on Twitter, as users compare its figures to the other games they play. Fate/Grand Order appears to be doing even better than Pokémon GO and Granblue Fantasy , which made estimated earnings of 3.7 billion (US$32.8 million) and 3.4 billion (US$30.2 million) respectively in October, although it's still behind Monster Strike , which made 14 billion yen (US$124 million). One user noted that although idol and performer games aimed at girls look like a saturated market, they appear to be selling well too, albeit not on Fate/Grand Order's scale.

Aniplex released the Fate/Grand Order smartphone game in Japan in summer 2015. The game received an English release in the United States and Canada in June 2017. Fate/Grand Order will receive TV anime and film projects. The game also recently celebrated 14 million downloads. According to the most recent figures, Fate/Grand Order made an estimated 3.5 billion yen (US$31 million) so far this month.
