Check whether refinancing your student loans makes sense.
Compare your current repayment plan with a refinanced rate and term to estimate whether you could lower payments or reduce total interest.
How this student loan refinance calculator helps
Refinancing can reduce borrowing costs when you qualify for a lower APR, but it may also extend repayment or remove federal borrower protections. This calculator helps compare both sides of the decision.
Formula: Monthly payment is calculated using the standard amortization formula, and total interest is based on the principal, rate, and term of the new loan.
Assumptions: The estimate assumes a consistent monthly payment, fixed rates, and no additional fees beyond a basic refinance fee. It does not model forgiveness programs or federal protections.
Worked example: A $30,000 balance at 6.8% APR over 10 years can cost roughly $10,000 in interest, while a 4.25% refinance over the same term may reduce total interest by thousands of dollars.
- Current balance: Outstanding principal on your student loans.
- Current APR: Your existing rate.
- Refinance APR: Rate available through a new lender.
- Loan term: Number of years for the new repayment schedule.
- Monthly savings: Potential reduction in payments or interest costs.
What the result means
The estimate compares the cost of staying with your current loan versus refinancing at a new rate. It highlights the difference in monthly payment and total interest, which helps you decide whether the lower rate is worth the tradeoff.

Frequently asked questions
- Could refinancing increase my monthly payment? Yes, if you shorten the term or skip a lower rate by extending the loan. The tool helps compare both outcomes.
- Does this include federal loan protections? No. Federal loans can offer borrower protections, repayment plans, and forgiveness programs that may outweigh a slightly higher rate.
Why this estimate matters
Use the Check whether refinancing your student loans makes sense. to test a realistic scenario before making a financial or health decision. The result is most helpful when you understand the inputs and how a small change in rate, payment, income, savings goal, or time horizon can change the outcome. This makes the calculator useful for planning, comparison, and early decision-making instead of relying on guesswork.
Because every household, budget, and payment schedule is different, the output should be treated as an estimate rather than a promise. Key assumptions like fixed costs, tax treatment, rate changes, or expected returns are built into the model and should be reviewed before making a commitment. When the decision is significant, compare a few scenarios, update the numbers as your situation changes, and consider professional guidance for taxes, debt strategy, mortgage planning, or long-term financial goals.
- Check your assumptions: Replace default values with your real numbers to see how the estimate changes.
- Compare scenarios: Test lower, base, and higher-cost versions of the same decision before finalizing your plan.
- Review trade-offs: A faster payoff or lower payment may affect cash flow, flexibility, or long-term goals.
- Update regularly: Revisit the tool whenever income, rates, costs, or goals change.
