So, the other day, I got thinking about Billie Jean King. You know, the tennis legend. It wasn’t random, I saw something about equal pay in sports pop up on my feed, and her name was right there, front and center. Made me remember watching old clips of her, especially that whole ‘Battle of the Sexes’ thing. What an icon, seriously.

Anyway, that led me down a bit of a rabbit hole. Curiosity got the better of me, and I started wondering, you know, after such a huge career and all her work off the court, what’s her financial situation like? So, I decided to look up Billie Jean King’s net worth.
My Process Looking This Up
It started pretty simply. I just grabbed my phone while sitting on the couch.
- First, I opened up my usual search engine.
- Typed in something straightforward like “Billie Jean King net worth”.
- Hit search and waited for the results to load up.
Right away, I saw a bunch of different websites throwing out numbers. It wasn’t just one clear answer, which honestly, happens a lot when you search for this kind of stuff online. Some celebrity net worth sites popped up, some sports news articles, even some biographical pages.
I clicked on a few of the top results. One site said one number, another site said something slightly different. You see ranges quite often. It’s kinda tricky with these things, because unless the person themselves reveals everything, it’s mostly guesswork based on public information like career winnings, estimated endorsement deals, investments, and maybe book sales or speaking fees.
I spent maybe 10-15 minutes just comparing the figures I was seeing. Most seemed to hover around a similar ballpark figure, though. I saw numbers mostly floating around the $20 million mark. Some were a bit lower, some maybe a tad higher, but that $20 million figure seemed to be the most common one popping up across different sources.

It got me thinking, though. For someone who absolutely changed the game, fought so hard for equal pay back when it was seriously unpopular, maybe that number doesn’t sound as high as some male athletes from that era or even later? But then again, prize money was way different back then, especially for women. Plus, she’s put so much into her foundations and activism, which is amazing.
So yeah, that was my little investigation. Started with a thought about equal pay, ended up clicking around trying to piece together an estimate of Billie Jean King’s net worth. The general consensus seems to be around $20 million, give or take. It’s interesting stuff to look into, seeing the legacy people build, both on the court and off it.
