How can you get a spouse excited about saving? Where should you stash emergency cash? And when is it okay to tap your reserve? By Janet Bodnar, Editor-at-Large July 30, 2008 I have a stubborn spouse who says that saving is great, but is not getting the point that saving early pays later. How can I get through?A few weeks ago, several twenty- and thirty-something staff members here at Kiplinger were sitting at the lunch table talking about what they wished they had learned earlier about money. Tops on the list: The magic of compounding, or how fast money can grow when you start saving early. That lesson might have a big impact on your spouse, too. For an illustration, see the letter below.

I'm about to start a graduate program for which I'm taking out loans, and I'll be a poor starving student for the next couple of years. But she thinks I should still add a couple of thousand dollars to my Roth IRA. I told her I don't have that kind of money. What do you think? Listen to your mother. Let's say you kick in an extra $2,000 to your IRA. If you earn an average of 10% per year -- the historical return for the stock market -- that $2,000 would grow into more than $107,000 by the time you're ready to retire. (Try our How much will my savings be worth? calculator.) That's a nice piece of change. Plus, stocks are a bargain right now, so it's a great time to invest.

Perhaps Mom (or some other generous relative) could come up with the cash. Handling your emergency fund I have been working for almost two years, and I've built a good-size emergency fund in a savings account with an online bank. Is there someplace better to put my money? Also, I need money for an engagement ring and a down payment on a house, which would tap out my emergency fund. Should I do this? Keeping your money in an online savings account is just fine. With an emergency fund, you're looking for safety and accessibility, and you're probably earning a competitive return on your money. Advertisement As for using the money, the whole point of an emergency fund is to have cash when you need it -- the car dies, your computer crashes, you have an unexpected medical bill. Tapping out your account on an engagement ring or a down payment defeats the purpose. I'd keep a minimum amount of cash -- three to six months' worth of living expenses is often recommended, but even $1,000 would be fine. If your "good-size" account is more than that, you'll have to set some priorities. If you want to splurge on a ring (which I don't recommend), the down payment may have to wait. If you want to buy a house, your fiancée may have to settle for a smaller gem, or none at all.
