Fixed student loan interest rates are generally a better option for most borrowers right now because variable student loan interest rates have been rising and are expected to continue going up.
A fixed rate will be locked in from the time you borrow until you finish repaying the loan — unless you refinance. Variable rates, on the other hand, are subject to change monthly or quarterly in response to economic conditions.
All federal student loans have fixed interest rates. It’s typically best to max out federal student loans before turning to private student loans because borrowers with federal loans qualify for income-based repayment plans and loan forgiveness programs — borrowers with private loans won’t.
If you opt for a private student loan, or if you refinance your existing student loans through a private lender, you can typically choose a fixed or variable rate.
Fixed or variable student loan?
If you’re unsure about the interest rate to choose, go with a fixed rate — it’s the safer option. If you’re willing to take a risk to potentially save a little extra money in interest — especially if you’re planning on paying off your student loan fast — consider a variable rate.
Fixed student loan rates are the safer bet
Fixed rates are locked in for the life of the loan. The only way to change a fixed interest rate is through student loan refinancing.
- There’s no chance that your rate will increase.
- Predictable monthly payments; the amount due won’t change.
- Rates typically start out higher than variable rates.
- You could miss out on interest savings if variable rates go lower.
Consider a fixed rate if
- Interest rates are on an upward swing.
- You don’t expect to pay off your loans anytime soon.
Variable student loan rates are a gamble
Variable rates are subject to change throughout the life of the loan. Student loan lenders typically set variable rates based on an economic indicator known as the London Interbank Offered Rate, or Libor. Lenders determine variable rates by adding the Libor rate to a base rate. If the Libor goes up, your rate goes up exactly that much.
Before getting a variable-rate student loan, ask lenders how often the rate is subject to change. Some adjust variable rates monthly, while others adjust every three months. Also, find out about the overall rate cap. Variable rates are often capped, but the caps can be as high as 25%.
- Rates typically start out lower than fixed rates.
- You could save on interest if variable rates don’t rise by too much.
- The recent trend has been toward rate increases for variable loans.
- Unpredictable monthly payments; the amount due could change.
- Your total number of monthly payments could change as the rate changes.
Consider a variable rate if
- You expect to pay off your loans before periodic rate increases erode any savings. Here’s what Libor index movement has looked like in the past.
- Interest rates are decreasing. For example, a borrower who took a Libor-linked loan at its 2007 peak would have seen the rate fall by over five percentage points two years later.
