A $100,000 salary sounds like the financial finish line, but plenty of people reach it and still wonder where their money went. The problem often has less to do with one outrageous purchase and more to do with a collection of ordinary expenses quietly nibbling away at every paycheck. Taxes take their share, housing takes another bite, and suddenly that impressive salary looks a lot less impressive in the checking account. Thankfully, those money leaks can become much easier to spot once they get a little attention.
