Lots of people refinance their student loans to lower their interest rate and save money. But refinancing isn’t the best financial choice for everyone.

Along with the benefits of refinancing student loans, there are also some drawbacks. Depending on your situation, the cons could outweigh the pros.

Before refinancing your student loans, consider whether any of the following conditions apply. If they do, you might be better off sticking with your current repayment plan.

When you refinance your student loans, you take out a new loan from a private lender. The lender repays all your loans, whether federal or private, so you don’t have to deal with your old loan servicers anymore. Then, it issues you a new loan with, hopefully, better terms.

Typically, people refinance to lower their interest rates or monthly payments. But even if you get more appealing terms, you still need the means to pay back your new loan. If you run into financial hardship, the private lender might not be flexible about your options.

If you’re worried about losing your income in the near future, you might not want to refinance just yet. Before turning all your student loans into one private loan, make sure you feel confident about your ability to make monthly payments.

Since you can only refinance with a private lender, you’ll no longer hold federal student loans. As a result, you’ll lose access to helpful federal programs, such as income-driven repayment.

Income-driven repayment plans adjust your monthly payments when you’re having trouble making them. Income-based repayment (IBR), for instance, caps your payments at 10 to 15 percent of your monthly income. The Revised Pay As You Earn (REPAYE) plan makes sure you’re not spending more than 10 percent.

Some of these plans even let you spread out your repayment over 20 to 25 years and will forgive any remaining balance after that time.

Most private lenders set a repayment cap at 15 to 20 years and typically don’t offer income-based protections. Before refinancing, consider whether or not you’ll need access to an income-driven repayment plan. If you will, wait to refinance your student debt.

The federal government offers several loan forgiveness programs, such as Public Service Loan Forgiveness (PSLF) and Teacher Loan Forgiveness. These programs cancel your remaining debt balance after a certain number of years of service.

If you refinance, you’ll no longer qualify for federal loan forgiveness, though. You might still be eligible for loan forgiveness and assistance programs from individual states or universities, but you won’t be able to participate in a federal program like PSLF.

Refinancing can save you lots of money over the life of your loan, if it lowers your interest rate. Let’s say your loans have an average weighted interest rate of 7% and you have nine years left of repayment. By refinancing, you lower the interest rate to 5% and choose a 10-year plan. Even after adding a year of repayment to your loan, you’ll save $2,337 in interest in the long run.

Student loan interest accumulates on a daily or monthly basis. If you can lower the rate significantly, you could save a lot of money. But if your average interest rate is already low, a refinancing lender may not be able to beat it.

Browse what’s available, and see what interest rates lenders will offer. SoFi, for instance, offers variable rates between 2.56% and 6.49% and fixed rates between 3.37% and 6.74%. If these rates aren’t much lower than what you have now, it might not be worth it to refinance.

Refinancing may not help you very much if you’re nearing the end of your repayment. When you refinance, you’ll choose a new plan, whether it’s five, 10, 15, or 20 years. If you’re already almost out of debt, switching to a new lender may not be worth the trouble.

Plus, you want to make sure you’re not adding time to your repayment plan. Unless your interest rate drops significantly, adding years onto your repayment plan would just make your debt more expensive.

Refinancing is most beneficial for those with a steady income who don’t need federal income-driven plans or forgiveness. If you’re worried about meeting monthly payments, it’s likely best to wait before switching your student loans to a private lender.

Before you decide to refinance, make sure that it would benefit you in the long run. Whether it reduces your interest rates or monthly payments, refinancing should make your student loans more manageable.

Even if you’re not a good candidate now, you might be better suited for refinancing in the future. So before changing to a new loan servicer, make sure you understand the full implications of your decision.

If you’re still not sure, ask yourself these questions before refinancing your student loans.
