Why you shouldn't pay for your kid's college

College degrees lead to higher pay, greater career options, and — research suggests — longer lifespans. But parents with college-bound children may feel trapped by the skyrocketing costs of education, which can also last a lifetime.

If you pony up, you could risking your retirement; if you don't, you could be risking your kid's future.

Indeed, the average graduate leaves school with nearly $30,000 in student debt, a sum that will reduce their future retirement savings by more than $300,000, according to a projection by insurance and financial research group Limra.

Likewise, parents' retirement savings are also getting put on the line because of skyrocketing costs. Nearly a third of parents in a T. Rowe Price study admitted they've made the risky choice of tapping their 401(k) plan to save for their kids' college.

That's a shortsighted move, said Sean T. Keating, a certified financial planner in Eatontown, New Jersey.

"You can always borrow money for college, but you can't borrow money for retirement," Keating said.

What do you do?

Finding compromise is possible if you plan ahead and follow the right order of operations, said Lazetta Rainey Braxton, a CFP and founder of the wealth advisory firm Financial Fountains.

"Middle income parents need to ensure their own financial stability first," Braxton said. "It's like putting on your airplane oxygen mask before you put on your children's."

Here are three key questions to ask yourself before you decide to open your wallet wide — or slam it shut.

One rule of thumb says that to maintain your standard of living, your savings at retirement should be high enough to replace at least 80 percent of your annual income each year, said Keating. Work backward from that assumption to see how much you can actually spare today, he said, also keeping in mind obligations like your mortgage payments and any other debts.

"You have to be aware of what you'd be sacrificing," said Erika Safran, a CFP and president of Safran Wealth Advisors in New York. "Will you run out of money at age 75? You must also consider medical expenses and where you will live."


In fact, many older adults end up forced to retire earlier than they expected because of illness or other unforeseen events, said Thomas Murphy, a financial planner in Dallas. So it pays to leave plenty of buffer room as you budget out any contribution to your child's college funds.

Make sure you are doing everything you can to free up easy cash, Safran said. Refinancing a mortgage right now could save you hundreds of dollars a month, for example. If you've done the math and realize you truly can't spare much (or any) cash for your kid's education, don't just leave your child hanging.
