In Chicago Tribune’s Going Broke? Here’s How to Change Gears, we get some advice from Dave Ramsey on how to get back on track if in debt. One of the more interesting insights came via a formula of how much your vehicle(s) should be worth. According to Ramsey, “the current value of all your vehicles should not exceed half your gross income. That’s so people don’t have too much tied up in things that are going down in value.” To sum it up, Ramsey stated “I’ve had people calling in, making $30,000 and owing $27,000 on their car. There’s no … way you can win doing that.”
