What are the current federal student loan interest rates for 2025-2026?

For loans disbursed July 1, 2025 through June 30, 2026: Direct Subsidized and Unsubsidized (undergraduate) 6.53%, Direct Unsubsidized (graduate and professional) 8.08%, Direct PLUS (parent and graduate) 9.08%. These are fixed rates for the life of each loan. Rates reset annually based on the 10-year Treasury note yield plus a statutory add-on.

What is the difference between subsidized and unsubsidized loans?

Subsidized loans: available to undergraduates with financial need; the federal government pays the interest while you are enrolled at least half-time, during the grace period, and during deferment. Unsubsidized loans: available to all eligible students regardless of need; interest accrues from the date of disbursement, including in-school and grace periods. The same repayment formulas apply to both once repayment begins.

Should I pay off student loans early or invest the extra money?

Compare your after-tax loan rate to expected after-tax investment returns. At 6.53% on a student loan, paying it off early yields a guaranteed 6.53% return. A diversified equity index fund has historically returned 7% to 10% annually, but with volatility and no guarantee. If you have high-interest debt (8%+), pay it first. At 6.53%, the decision is genuinely close and depends on risk tolerance and whether you have employer 401k matching available.

What happens if I cannot afford my student loan payments?

Contact your federal loan servicer before missing a payment. Options include: income-driven repayment (lower payments based on income), deferment (temporary suspension of payments during economic hardship or school re-enrollment), and forbearance (up to 12 months of reduced or paused payments, though interest accrues). Defaulting on federal loans has severe consequences including wage garnishment, tax refund seizure, and credit damage.

Introduction

The average 2025 college graduate carries $29,400 in federal student loan debt, according to the College Board's Annual Survey of Colleges. What most graduates do not calculate before signing repayment paperwork is the total cost -- not the monthly payment, but the total dollars repaid over 10 years. A $29,400 loan at 6.53% on the standard 10-year plan costs $39,900 in total: $10,500 in interest on top of principal. Add extra monthly payments or understand income-driven plan tradeoffs and that number changes significantly. This estimator models your repayment timeline under standard, graduated, and extended plans, shows total interest paid, and calculates how extra payments shorten both the timeline and the total cost.

What This Calculator Does

This loan repayment estimator calculates monthly payments, total interest paid, and payoff dates across multiple federal repayment plan options. Enter your loan balance, interest rate, and loan term to compare standard 10-year repayment, graduated repayment (payments start lower and increase every two years), and extended repayment (up to 25 years). The tool also models extra monthly payments and shows the time and interest savings from accelerated payoff.

The Formula

Monthly Payment = P x [r(1+r)^n] / [(1+r)^n - 1] | Total Cost = Monthly Payment x n | Total Interest = Total Cost - P

P is the principal loan balance, r is the monthly interest rate (annual rate divided by 12), and n is the number of monthly payments (years x 12). This is the standard amortization formula used by all lenders. Each payment covers the interest on the current balance first, with the remainder reducing principal. Extra payments apply directly to principal, reducing future interest accrual and shortening the payoff timeline.

Step-by-Step Example

Enter loan details

Balance: $32,000. Interest rate: 6.53% (2025-2026 federal undergraduate direct unsubsidized rate). Term: 10 years (standard plan).

Calculate standard monthly payment

Monthly rate: 6.53% / 12 = 0.5442%. n = 120 months. Payment = $32,000 x [0.005442 x (1.005442)^120] / [(1.005442)^120 - 1] = $361.22/month.

Calculate total interest paid

Total paid: $361.22 x 120 = $43,346. Total interest: $43,346 - $32,000 = $11,346. Every month you extend the term increases total interest.

Model extra payments

Adding $75/month extra ($436.22/month total): Payoff in 93 months (7 years 9 months). Total interest: $8,736. Savings: $2,610 in interest and 2 years 3 months earlier payoff.

Real-World Use Cases

Post-Graduation Budget Planning

A new graduate earning $48,000 needs to know whether their $361/month standard payment is affordable alongside rent, food, and transportation. Running the extended 25-year plan shows a $224/month payment -- manageable -- but adds $21,000 in extra interest over the loan life. The tradeoff is visible immediately.

Refinancing Evaluation

A borrower 3 years into a 10-year federal loan at 6.53% receives a private refinance offer at 4.8%. This calculator shows remaining balance, remaining interest under the federal loan, and what the new payment and total cost would be at 4.8% over 7 years. The savings justify refinancing -- but only after confirming PSLF is not a factor.

Multiple Loan Payoff Strategy

A graduate with three loans at different rates and balances calculates the monthly payment and total interest for each. The highest-rate loan should be paid off first (debt avalanche method). This calculator models each loan individually so the payoff sequence can be planned accurately.

Comparison

Repayment Plan	Typical Term	Monthly Payment ($32k at 6.53%)	Total Interest	Best For
Standard	10 years	$361/month	$11,346	Minimizing total cost if affordable
Graduated	10 years	$202-$607/month	$13,100+	Expected income growth early career
Extended	25 years	$224/month	$35,200+	Very high balance relative to income
Income-Driven (IBR new)	20 years	Based on income	Varies widely	Income below 150% poverty line
Extra $75/month	~7.75 years	$436/month	$8,736	Accelerated payoff if cashflow allows

Common Mistakes to Avoid

Choosing extended repayment for the lower monthly payment without calculating total interest. Extending from 10 to 25 years on a $32,000 loan at 6.53% adds over $23,000 in interest. The lower payment is paid for many times over in total cost.
Refinancing federal loans to private before confirming PSLF ineligibility. Federal Public Service Loan Forgiveness forgives remaining balances after 10 years for qualifying employers. Refinancing to a private loan permanently eliminates eligibility. Even a 2% rate reduction does not offset losing PSLF if your forgiveness would occur within 10 years.
Making extra payments without directing them to principal reduction. Call your servicer or use the online portal to specify that extra payments reduce principal. By default, some servicers apply overpayments to future scheduled payments, which does not reduce your balance or shorten your term.
Ignoring the grace period interest on unsubsidized loans. Unsubsidized federal loans begin accruing interest at disbursement, including during the 6-month post-graduation grace period. That interest capitalizes (adds to principal) when repayment begins, increasing your starting balance beyond the original disbursed amount.

Accuracy and Disclaimer

This estimator uses the 2025-2026 federal student loan interest rates. Actual repayment amounts depend on your specific loan type, servicer, and repayment plan. Federal loan programs, forgiveness rules, and income-driven repayment plan availability are subject to legislative and regulatory changes. This tool is for planning purposes only. Consult studentaid.gov or your loan servicer for official repayment calculations.

Conclusion

The standard 10-year repayment plan almost always costs less in total interest than extended or graduated plans, even though monthly payments are higher. Run all three scenarios before choosing a repayment plan. If your balance is large relative to your starting salary, also use the Student Loan IDR Estimator to compare income-driven options.
