As her Discogs page shows, Fiona Apple is indeed a very sporadic artist, with only a total of four albums to her name, and the most recent one came out in 2012. Of course, it must be noted that they're quite popular albums, and since she's a singer-songwriter, it's probably safe to assume that there are fairly few superstar songwriting teams taking their cut.
As such, Celebrity Net Worth estimates that Apple has a net worth of around $14 million. However, this figure might soon have to be re-estimated, seeing as Apple revealed in a 2019 interview with Vulture that she was in the process of wrapping up a new album, which she hopes to will be ready in 2020.
