Financing a college degree is a major investment that often requires student loans. Whether you have federal student loans, private loans, or a combination of both, establishing a repayment strategy is essential. Understanding how interest accrues during and after your studies will allow you to make smart refinancing decisions and pay off your balances faster.
Federal student loans are funded by the government and come with benefits like income-driven repayment (IDR) plans, deferment options, and public service loan forgiveness (PSLF). Private student loans are offered by banks, credit unions, and online lenders, with interest rates based on your credit score. Private loans lack the flexible protection options of federal loans but may offer lower rates for highly qualified applicants.

Student loan interest accumulates daily based on your outstanding principal. Direct Subsidized federal loans do not accrue interest while you are in school at least half-time, as the government pays it. Direct Unsubsidized and private student loans begin accruing interest immediately upon disbursement, meaning your balance grows while you are in college.
To see how interest accumulates on your balances, check our interest rate calculator or look at the standard loan estimator.
Refinancing involves replacing multiple student loans with a single new loan from a private lender. If interest rates have dropped or your credit score has improved since you went to school, refinancing can secure you a lower rate. This decreases your monthly payment and saves you money in total interest costs. However, refinancing federal loans into a private loan means forfeiting federal protections.
To check how a lower consolidated rate affects your monthly budget, try our amortization calculator or plan your savings with the monthly savings planner.
Your debt-to-income (DTI) ratio compares your monthly debt payments to your gross monthly paycheck. Lenders use DTI to determine your ability to buy a home or secure other financing. Keeping student loan payments low relative to your income is key to maintaining healthy personal finance metrics.

Let us look at a standard repayment example. Suppose a student graduates with $30,000 in student debt at a 5% interest rate: - Under a standard 10-year repayment term, the monthly payment will be approximately $318. - The total payments over the 10 years will sum up to $38,184. - The borrower will pay a total of $8,184 in interest charges alone.
Paying off student debt early requires discipline. You can pay more than the minimum payment each month, direct work bonuses or tax refunds toward the principal, or use the avalanche method by focusing extra payments on the loan with the highest interest rate.
