GRAND RAPIDS (WZZM) -- College loan rates are set to double by July 1 unless lawmakers act.

It's something that will affect Sandy Theisen. "I'm trying to put money into my retirement."

And not just her future, but her son's. After freshman year, her son already has $11,000 in college loans. That number could go up if the government loan rate doubles from 3.4 percent to 6.8 percent.

Theisen says, "I don't like to have any kind of debt, I'm the type who wants to pay off things right away."

Right now students pay about $24,000 in Michigan for their college education, that could increase if the rates are doubled.

We had Nicholas Danner at GreenPath do the math. "That's about an extra $3,500-$4000 depending on what you've got."

$4,000 per household is a large sum of money not going into the economy. "I think it's a good thing to remain at 3.4 percent, not just for individuals, but for the economy as a whole," says Theisen.

While parent loans likely won't change, Stafford loans will go up. Sandy has both, and has this request for lawmakers: "I ask them to reconsider, the children are the future of our country and they need to be educated."

And with rising rates she worries, they won't be able to afford that education.
