I've been thinking half the day about this question and in retrospect I don't think he did paid child support --> one reason of several reasons Ailyn was after him I suppose.

I still do think he spent lots of money on fuel, armor, repairs, equipment, ammo, ships, rent, the ladies, food/drink... maybe saved the rest for retirement?

Actually it's a good question: What would Boba spend his credits on?

Well, hummm.... he had a daughter and a wife.. so maybe he did send child support??? But that would only be a small part of that big money he makes.

Fuel, repairs, food, ammo, armor, rent, drinks (he did hang out a Jabba's), maybe tip the ladies/dancers @ Jabba's... but still seems to leave a chunk of change in his account (maybe).

Most Mandalorians are known to adopt/raise and train kids -- although Boba left Ailyn (his own daughter) behind it is possible that he did donate to orphanages... Just because he could not raise his own kid does not mean he did not donate to help others to do so....

Hummm.. interesting question you've asked

So, Boba's paid some insane amounts of money for his services... and all that cash just keeps piling up... what do you think he does with it/wants to do with it?
I mean, it's obvious that a good amount may go into meals, fuel, weaponry, disguises, etc. but he has more than enough to cover all of those expenses.

Does it ever actually say in any of the books/comics what he does with it or wants to do with it?
I was kinda thinking that maybe he likes to anonymously donate some of his credits...? Maybe to organizations that deal with environmental issues (what? Maybe he cares about the Ewok population!) or to ones that help support orphanes (since he was once one himself).
I guess I say this because, admittedly, I like to see Boba Fett with a tender side. I'd just hate to think he hoardes all that money all to himself with nothing to do with it!!

Other than that, I hope he takes vacations every once in while... to a Spa on Kamino... Hologram Fun World (which I'm sure is totally canon).

*sigh* Well, it's late at night, I can't sleep, & I have nothing better to do... so I was just trying to kill some time. XD

Funny thing in your last typed line: 'just trying to kill some time' I feel might be what Boba might've did; Besides his 'job' and maintaining his ship & arsenal, I'm sure there were alot of unspent credits because how much could one really spend without actually throwing it away?

to buy han solo figures maybe?

Maybe he would  encase them in carbonite himself. LOL

No... seriously. idk. He probably saves it and uses it when he needs it... He's not a man of showing much interest so I wouldn't know...
