You’ll want at least enough to cover your monthly bills. But It’s also possible to have too much money sitting in a checking account.
It’s a question everybody likely wonders, from the billionaire to the person living paycheck to paycheck: How much money should I keep in my checking account?
Of course, if you’re a billionaire, deciding what to keep in your checking account is more of a “fun” academic exercise. If you’re constantly struggling with cash flow, it’s a far more important and non-frivolous question.
