🎓 What Is Student Loan Refinancing?
Refinancing means taking out a new private loan — ideally at a lower interest rate — to pay off one or more existing student loans. The new loan replaces the old one entirely: same balance (roughly), new rate, new term, new lender. It's different from federal consolidation, which combines federal loans into one federal loan without necessarily lowering the rate. Refinancing can meaningfully cut interest costs, but the term you choose changes the outcome as much as the rate does — which is the part most people miss.
🖱️ Try It Yourself: Three Real Scenarios
Click any scenario below to load it into the calculator above and see the real numbers instantly.
A $40,000 balance at 6.8% with 10 years remaining, refinanced to 4.5% over just 7 years. The payment rises to $556.01/month, but total interest drops to $6,704.54 — a savings of $8,534.02 compared to staying on the current loan. Shorter terms are where refinancing saves the most, if the higher payment is affordable.
Same balance and rates, but keeping the same 10-year term. The payment drops to $414.55/month (down from $460.32) and total interest falls to $9,746.44 — saving $5,492.12 while also reducing the monthly payment. This is the balanced outcome most refinance calculators default to.
Same balance and rates again, but stretched to a 15-year term. The payment drops dramatically to $306.00/month — but total interest barely improves, at $15,079.52, saving just $159.04 versus staying put. A lower rate stretched over more time can erase almost the entire benefit of refinancing.
🔢 Formula Used
Where r is the monthly interest rate and n is the total number of monthly payments. This calculator runs that formula twice — once for your current loan's remaining term and rate, once for the refinance offer's new term and rate — then compares the two total-interest figures directly.
Before refinancing federal loans: converting federal student loans to a private refinance loan is permanent and forfeits income-driven repayment plans, federal deferment and forbearance, and forgiveness programs like Public Service Loan Forgiveness. Refinancing purely private loans, or federal loans you're confident you'll never need those protections on, doesn't carry this risk.
👥 Who This Is For
- Graduates with stable income and good credit evaluating whether a lower advertised rate is actually worth it
- Anyone comparing multiple refinance offers with different rate-and-term combinations
- Borrowers deciding between a lower payment and lower total interest — this calculator shows exactly where that trade-off lands
- Private student loan holders without federal protections to lose, for whom refinancing carries little downside

What is student loan refinancing?
Taking out a new private loan, ideally at a lower rate, to pay off existing student loans. It differs from federal consolidation, which combines federal loans without necessarily lowering the rate.
Do I lose federal protections if I refinance federal student loans?
Yes — refinancing with a private lender permanently converts them to private debt, forfeiting income-driven repayment, federal deferment/forbearance, and programs like Public Service Loan Forgiveness.
Does a shorter or longer refinance term save more money?
A shorter term almost always saves more in total interest, even at the same rate, though it requires a higher payment. A longer term lowers the payment but can shrink or eliminate the savings.
Is a lower interest rate always worth refinancing for?
Not automatically — if the new term is significantly longer, a lower rate can still result in similar or higher total interest, since the loan accrues interest for more months overall.
Can I refinance only some of my student loans?
Yes — most lenders allow refinancing a subset, letting borrowers keep specific federal loans for their protections while refinancing others.
What credit score is typically needed to refinance student loans?
Most lenders look for good to excellent credit, commonly high 600s to 700s or higher, along with stable income, though requirements vary by lender.
