It's tough to say how much money Sal from Impractical Jokers has. He's never been one to flaunt his wealth, and he's pretty good at keeping a low profile. But we can make some educated guesses based on what we know about him.
Sal comes from a wealthy family. His father was a successful businessman, and Sal inherited some of that money. He also married into a wealthy family - his wife is the daughter of a millionaire. So it's safe to say that Sal has access to quite a bit of money.
However, he doesn't seem to spend very much of it. He drives an older model car and lives in a relatively modest home. He also doesn't appear to spend much on clothes or other luxuries. This could mean that he either doesn't have very much money, or that he's just frugal with his spending.
Either way, Sal from Impractical Jokers is probably doing alright for himself financially. He's certainly not as rich as some of the other members of the cast, but he seems to be doing just fine.
