This student loan move could save you thousands

There may not be a magic bullet for getting out of student loan debt, but there is a holy grail, of sorts, for some borrowers: student loan refinancing.

There may not be a magic bullet for getting out of student loan debt, but there is a holy grail, of sorts, for some borrowers: student loan refinancing.

Here’s how it works: If you qualify, a lender will buy your existing loan, or loans, and issue a new one. Depending on your credit, you could get a lower interest rate, which would save you money in the long run.

Say, for example, you left college with a $30,000 private student loan with a 7% interest rate and a standard 10-year loan term. If you refinanced that loan right away at 3.5%, you’d save more than $6,000 in interest over the life of your loan. You could use the money to start an emergency fund, save for retirement or go on vacation.

Here’s what you need to know about refinancing your student loans.

How to qualify

In general, you’ll need three things to qualify:

1. Solid credit score: Most lenders require a score of 700 or higher. If your score is lower, you can apply with a co-signer whose score qualifies.
2. Low debt-to-income ratio: The lower your debt is in relation to your income, the better. Aim for a ratio that’s lower than 50%. For example, if you make $60,000 a year, your total debt should be below $30,000.
3. Steady source of income: Borrowers with traditionally stable, high-paying careers will find it easier to qualify. Freelancers and those who are between jobs will have a harder time qualifying.

How to make it work

Refinancing is a great option for borrowers who have private loans with high interest rates. Federal loans also can be refinanced, but you’ll lose access to federal loan protections, such as income-driven repayment and forgiveness options. That’s why it’s usually best to exclude federal loans during refinancing.

Nerd Tip: If a lender offers prequalification, you might want to go through that process to get an idea of how much you could save without having a hard inquiry on your credit history, which lowers your credit score.

To determine if refinancing is a good option, compare your current loan terms against your potential loan terms. You’ll save the most money by getting your interest rate as low as possible. Consider other aspects of your loan as well to get the full picture. For example, if you have a loan with a 6% interest rate, refinancing it at 5% would make sense only if you didn’t have to extend the loan term.

If you don’t qualify

You can use a co-signer if your own credit score isn’t 700 or above. But if you’d rather refinance on your own, focus on paying your bills on time and reducing any credit card debt to boost your credit score before applying.

If refinancing makes sense and you’re willing to make the effort, it could help you save thousands of dollars in interest payments over the life of your loan. That’s at least worth considering.
