How It Works
Refinancing student debt only makes sense when the new terms beat what you already carry, and this tool puts the two side by side. It weighs your existing loans against a proposed replacement to estimate your monthly savings, the total interest you would avoid, and how the payoff timeline shifts.
The comparison starts with the full cost of your current loans, built from the principal, interest rate, and remaining term. It then runs the same projection on the refinanced loan using the new rate and the term you select. The gap between the two, in both total interest and monthly payment, is where the potential savings show up.
Pull rate quotes from several lenders before committing, and look at both fixed and variable options rather than the first offer. Stretching the term to drag the monthly payment down is tempting, but a longer schedule usually means more interest paid before the balance clears.
Example: Should Sarah Refinance Her $50,000 Student Loan?
- 1 Sarah has a $50,000 student loan with a 6.5% interest rate and 8 years (96 months) remaining. A new lender offers her a 4.0% interest rate for a 7-year (84 months) refinance term.
- 2 Current Loan: Using a loan payment formula, her current monthly payment is approximately $666.27. Total interest paid over 8 years: $13,962. New Loan: With a 4.0% interest rate over 7 years, her new monthly payment would be approximately $695.53. Total interest paid over 7 years: $8,424.
- 3 While her new monthly payment is slightly higher ($29.26 more), she would save a significant $5,538 in total interest ($13,962 - $8,424) and repay her loan one year sooner.
- 4 In this scenario, even with a slightly higher monthly payment, refinancing is beneficial for Sarah due to the substantial interest savings and shorter repayment period. This illustrates the importance of looking at both monthly payments and total interest paid.
