I'm sure he's worth quite a bit. Seeing as most of the Fugazi records and the Minor threat record sold close to 1 million copies each and it didn't hurt that Ian is also the owner of the record label. I can't see them having made a ton of money off of touring due to the band only charging $6 a ticket and not selling any merchandise at shows. The band never sold Tshirts. I've heard rumors for years about him having millions in the bank and driving a 95 Honda Accord and wearing thrift shop clothes....
