Dear Liz: We have a son who is a high school junior and who is planning on going to college. We met with a college financial planner who suggest we put money in a whole life insurance policy as a way to help get more financial aid. Is that a good idea?

Answer: Your “college financial planner” is actually an insurance salesperson who hopes to make a big commission by talking you into an expensive policy you probably don’t need.

The salesperson is correct that buying a cash-value life insurance policy is one way to hide assets from college financial planning formulas. Some would question the ethics of trying to look poorer to get more aid, but the bottom line is that for most families, there are better ways to get an affordable education.

First, you should understand that assets owned by parents get favorable treatment in financial aid formulas. Some assets, such as retirement accounts and home equity, aren’t counted at all by the Free Application for Federal Student Aid or FAFSA. Parents also get to exempt a certain amount of assets based on their age. The closer the parents are to retirement, the greater the amount of non-retirement assets they’re able to shield.

Consider using the “expected family contribution calculator” at FinAid.org and the net cost calculators posted on the Web sites of the colleges your son is considering. Do the calculations with and without the money you’re trying to hide to see what difference the money really makes.

Most families don’t have enough “countable” assets to worry about their effect on financial aid formulas, said college aid expert Lynn O’Shaughnessy, author of “The College Solution.” Those that do have substantial assets have several options to reduce their potential impact, including spending down any custodial accounts, paying off debt and maxing out retirement plan contributions in the years before applying for college.

Another thing to consider is that most financial aid these days comes as loans that need to be repaid, rather than as scholarships or grants that don’t. So boosting your financial aid eligibility could just mean getting into more debt.

Meanwhile, it’s generally not a good idea to buy life insurance if you don’t need life insurance. The policy could wind up costing you a lot more than you’d save on financial aid.

If you’re still considering this policy, run the scheme past a fee-only financial planner—one who doesn’t stand to benefit financially from the investment—for an objective second opinion.
