How to bank hundreds of dollars more each month

Robert Shiller, the Nobel Prize-winning economist, offered some simple advice for people trying to get ahead when he visited Yahoo Finance recently: Live like a student.

“My students are living alright,” Shiller said. “I’ve suggested to them, why don’t you just continue to live at that level after you get a job? It would pile up into a lot of money.”

Struggling workers might take offense at a comfortable, accomplished Yale professor suggesting middle-class Americans should subsist on ramen noodles and hand-me-down furniture.

But Shiller, like other economists, is addressing a stark reality: Many Americans live beyond their means, with 20% of adults spending more than they earn, according to the Federal Reserve. Less that half of all adult Americans have enough money saved to cover a $400 financial emergency. Millions more are far short of the funds they’ll need to retire comfortably.

Shiller’s basic point is that the longer working folks can hold onto the frugal habits they're forced to adopt when money is tight, the better off they’ll be when they have to come up with money for their kids’ college, cover the cost of a medical emergency or ride out an unexpected bout of unemployment -- and then, if there’s anything left, fund retirement.

The concept is easy to understand — and damn hard to execute. I tried it out on myself — theoretically -- and discovered that if I were to live like a student, here’s what I’d have to change:

Stop fixing up my house. Owning the home isn’t really the problem, since it’s a pretty good deal for me, compared with renting. But the amount I spend on upgrades, maintenance, landscaping and basic repairs takes hundreds of dollars out of my wallet every month (and sometimes, every week).

Estimated savings from caring less about my house: $300 per month.

Make do with my old car. It runs well and has most basic features -- and it’s paid for. But I want heated seats! I’ve already identified a couple new models I’d love to check out, but I guess I can live with my eight-year-old Mazda for a few more years.

Savings if I don't take on new monthly car payments: $300 to $400 per month.

Tolerate dumb TV. I just bought my first smart TV. Not because my old TV broke, but because who wants a dumb TV when you can have a smart one connected directly to the Internet? Of course, now that I think about it, I got by with a puny TV — artfully outfitted with rabbit ears — back when I was first starting out. And I have to admit, I’ve also upgraded my smartphone, tablet and several other gizmos simply because a newer model seemed better.
