Student Loan Refinance Term Comparison
This calculator lines up multiple refinance term lengths side by side so you can see how monthly payment and total interest change as the term grows or shrinks. Enter your balance and a refinance rate to generate columns for common terms. Shorter terms cost more per month but dramatically less in total interest.
New monthly payment
You pay today, so that is a month back in your pocket.
That is more than the you pay today — the shorter term costs more each month but clears the debt sooner.

No switching cost to earn back — you are ahead from the first payment, by over the life of the loan.
You earn the switching cost back after payments — around .
At these numbers the new loan never pays for itself: the monthly payment does not fall.
Careful — the lower payment comes from a longer term. Over the full term this deal costs more than staying put.
Both loans are modelled as fixed-rate, fully amortising, with no missed months. A refinance replaces your loan with a brand-new private loan — see what that costs you below.

What you give up when federal loans go private
- Income-driven repayment. A private lender sets one payment; it does not fall when your income does.
- Federal forgiveness programmes, including Public Service Loan Forgiveness and any income-driven forgiveness after the full repayment term.
- Federal discharge on death or total and permanent disability — private lenders decide their own policy.
- Federal deferment and forbearance rights, and the federal rehabilitation route out of default.
- The decision is one-way. Once a federal loan is refinanced privately, it cannot be turned back into a federal loan.
Refinancing private loans into a cheaper private loan gives up none of this — it is federal balances that carry the risk.
Shorter Terms: Higher Payments, Lower Total Cost
A five-year refinance term on an illustrative $55,000 balance produces the highest monthly payment of any standard option, but the total interest paid is the lowest because the principal has far fewer months to accumulate daily interest charges. Moving from a ten-year term to a five-year term roughly doubles the monthly payment while cutting total interest by more than half.
The calculator displays this trade-off numerically for each term. For borrowers with stable income and room in the monthly budget, a shorter term extracts the maximum savings from a rate reduction. However, private loans do not offer income-driven repayment or forbearance, so the higher fixed payment must be sustainable through job changes and other disruptions. If you are uncertain about cash-flow stability, the seven-year column often represents a middle ground: substantially less total interest than a ten-year term with a monthly payment that leaves some budgetary margin. Enter your balance and rate to see the exact spread across all five columns.
Longer Terms: When They Help and When They Hurt
A fifteen- or twenty-year refinance term produces the lowest monthly payment, which can relieve budget pressure, especially for high-balance borrowers. But the interest cost rises sharply. On that same illustrative $55,000 balance, a twenty-year term can add tens of thousands of dollars in total interest compared to a ten-year term, even at the same rate. The calculator makes this visible at a glance.
Longer terms are sometimes justified when the alternative is staying on a high-rate federal loan with no plan for forgiveness. If the rate reduction is large enough, even a twenty-year private term may cost less in total interest than the remaining federal repayment, though the borrower permanently gives up income-driven repayment, PSLF, forbearance, and disability discharge. Borrowers on student-loan forums report that choosing a longer term and then making extra payments toward principal offers a blend of safety and efficiency: the low required payment protects cash flow, while voluntary extras cut the effective term.

Term options and rates are illustrative. Actual terms offered depend on lender, balance, and creditworthiness. This is not a loan offer.
