What are student loans?

A student loan is money obtained to help you pay for college from the government or a private organization such as a bank. Depending on the type of loan you take out, you can get money to cover most, if not all, of your education and related expenses.

Federal and private student loans are the two types of loans available. Both can cover your school costs, but the interest rates and repayment options are vastly different. That’s because federal loans are overseen by federal programs, like FAFSA, while private loans’ terms are totally between the lender and the borrower.

There are 3 kinds of Federal loans:

  • Direct Subsidized Loans: These loans are based on financial need, determined by the difference between the cost of attending your desired school and your family’s income. The Department of Education helps to cover some of the initial costs of interest on these loans, too.
  • Direct Unsubsidized Loans: These loans are not based on financial need, but instead the amount that your school costs to attend. Students are responsible for the full value of the interest on direct unsubsidized loans.
  • Direct PLUS Loans: These are loans that students’ parents can take out if other forms of funding have been exhausted. 

Private loans, on the other hand, are not as consistent because they are lent by private companies. Lenders such as a local bank, national bank, credit union, or internet lenders offer private student loans. Interest rates vary by lender, whereas federal loans often have set rates. Keep in mind that you’ll need to get your credit checked before applying.

What else you should know about student loans

You’re not necessarily stuck with the loans that you took out when you were 18 years old. If you don’t like the terms of your current loans, or the companies you’re working with, you may be able to refinance your student loans. 

Refinancing student loans often allow borrowers to qualify for a lower interest rate, which could save them thousands of dollars or more. Borrowers with a low debt-to-income ratio, a solid credit score, and a steady job are often preferred by student loan refinancing lenders. That said, even if you don’t have a high salary or a flawless credit score, you may be eligible for student loan refinancing. 

You can refinance both private and federal loans, but it’s important to note that refinancing federal loans through a private lender could result in you losing special privileges like deferment and forbearance. Because private lenders rarely offer deferment or forbearance, consider refinancing a federal loan when you’re sure of your financial stability.

It’s also important to think about what repayment plan works best for you when determining which loan is your best option. When it comes to private and federal insurance, there are certain distinctions. Federal loans, for example, are frequently not paid until after your graduation and grace period, whereas private loans may require payments while you are still enrolled. Some federal loans also provide you the option of tying your monthly payment to your post-college income. 

Ultimately, it just comes down to your personal financial situation, and the choices that you deem worthwhile in the long-term. For more details that are important to keep in mind, check out our article on important student loan info

What do I need to know for a student loan calculator

If you’re not sure of the information you need to get an accurate answer from the calculator, here’s how it works broken down by category. 

Loan Amount

This is the total amount that your loan is for. Most lenders will display the current balance of your loan on their website, or you may be able to call to find out where your balance stands. 

Interest Rate

This is the amount of interest applied to your loan balance each month. The calculator will account for the compounding accrual of interest on your loan over time. 

Loan Term

Your loan term is the duration of your loan. It’s the number of years that you agreed you will pay off your loan within, and it can affect your interest rate and the size of your monthly payments. 

Federal Loans

Be sure to include all your federal loans when inputting data, including subsidized loans, unsubsidized loans, and direct PLUS loans. 

Private Loans

Lastly, include the balance on any private loans you may hold. 

What do my results mean?

Here’s what the different results you might get mean:

  • Monthly payment is the total amount that you pay each month. It’s the amount that you are billed by the company based on the duration of the loan, the amount you borrowed, the interest rate, and any other fees associated with your loan.
  • Interest paid is the amount that you pay your lender in interest, which is essentially the cost of your loan. For loans with higher interest rates, the proportion of your total bill that is purely interest will be higher than it would be for a loan with a lower interest rate. This is why many borrowers seek a low interest rate.
  • Total principal is the amount that you borrowed in the first place, before taking into account interest or monthly payments. Your principal generally doesn’t change, but the total amount you owe can increase as interest is applied to your loan, and can decrease as you make payments on the loan.
