9 things that will blow up your finances

In honor of the 40th birthday of 'The Anarchist Cookbook,' here are a few really bad ideas -- bombs, you might call them.

Once upon a time, no self-serving radical activist would be caught dead without "The Anarchist Cookbook" and its misguided recipes for making homemade bombs, tear gas and other sinister items out of everyday household products.

In fact, Lifehacker recently put out a post "celebrating" the cookbook's 40th anniversary with a bunch of relatively benign but dangerous do-it-yourself ideas you'd probably be better off staying away from, like making a pair of heated underwear and driving your car with an iPhone.


Of course, Lifehacker's post got me thinking. If I were to write my own version of "The Anarchist Cookbook" that focused on dubious ideas that were guaranteed to -- if you'll pardon the expression -- blow up your personal finances, what recipes for disaster would I include in it?


Here are a few financial Molotov cocktails for you:

Co-signing a loan. Talk about a bad idea. When lenders ask for a co-signer, they essentially are saying they don't believe the borrower will ever repay the loan. If you agree to co-sign a loan, you will be fully liable for the full amount of the loan should the borrower flake out -- and the odds are, he will. Before you sign on the dotted line, ask yourself: Is it really worth putting your financial future in the hands of someone who is a poor credit risk?


Delaying retirement savings contributions. If you start saving $200 a month at age 24 -- earning a modest return of only 5% -- you'll have more than $323,000 by the time you reach age 65. However, if you delay your contributions until you reach age 50, then you'll have to save $1,210 every month for 15 years with the same returns to end up in the same position. Good luck with that. Unfortunately, the money you save when you are older is much less valuable than the money you save when you are younger. That's because compound interest is an ally of the young.

Borrowing from your 401k retirement plan. Yes, you pay yourself back with interest. And, yes, the loan itself isn't taxed. However, assuming you actually use the loan to pay for something else, you'll repay the loan with money that is taxed. Then, when you finally make a 401k withdrawal in retirement, you will have to pay taxes again. So, in essence, your loan eventually ends up being double taxed. Not very smart.

Using credit card cash advance checks found in your mailbox. Oh sure, it may seem like a great idea at the time, but savvy consumers know that those checks usually come with fees and can have exorbitant triple-digit annual percentage rates like those you get with payday loans. Not only that, but unlike the float typically offered on credit card purchases, there is no grace period for cash advances. So interest begins accruing from the day that cash advance is taken.

Overpaying for a college education. Nothing says "financial albatross" like having a massive college loan to pay off with no prospect of ever finding a well-paying job. So before you go off and spend tens or even hundreds of thousands of dollars on an expensive college education, you'd be wise to select a degree that requires you to take courses that are always in high demand by employers -- if you plan on getting a reasonably quick and decent return on your college investment, that is. And if you still insist on majoring in worthless degrees like underwater basket weaving, make sure you do it at a relatively inexpensive state college.

Paying for your kids' education with your retirement funds. Speaking of college, saving for retirement is arguably the most critical financial task we have as adults, so why do so many parents risk sacrificing the quality of their golden years by paying for their kids' college education? Instead, parents should use that money to ensure their financial security in retirement. Remember, our kids will have four full decades to pay off those low-interest loans after graduating; the same can't be said for us parents.


Investing in a stock or financial product without doing your own research. There is an old saying that the less you understand about a stock or financial instrument like a variable annuity, the more it's going to cost you. It's true. Relying solely on a broker who gets paid a commission when you buy is asking for big trouble.

Marrying before determining financial compatibility. Sure, you can stick your head in the sand and naively assume marriage is a sacrosanct declaration of love and fidelity.  However, marriage has serious financial effects that could cost hundreds of thousands of dollars down the road for incompatible couples who end up filing for divorce. The truth is, financial compatibility is as important as emotional and physical compatibility. It is one of the greatest predictors of whether your relationship will survive long term, so make sure you're financially compatible before tying the knot.

Using your credit card when you don't have enough money to pay it off. When used responsibly, credit cards are a consumer's best friend. However, they should be used only if the balance can be fully paid off before the interest-free grace period expires. Otherwise, you'll not only subject yourself to interest charges that can approach 30% and make it exceedingly difficult to pay off your debt, but you also risk wreaking havoc on your credit rating if you start missing payments.

There. Next time you're looking to throw a few wrenches into your personal finances, feel free to use the recipes from this cookbook. When you do, I promise you'll discover why anarchy, by definition, doesn't rule.
