Graduate School Student Loan Calculator
Calculate payments on an $80,000 graduate school loan at 7.0% over 15 years. Monthly payment is ~$719/mo. Explore refinancing, PSLF, and accelerated payoff strategies.
Graduate school loans typically carry higher interest rates than undergraduate borrowing -- Direct Unsubsidized loans for graduate students are priced at 7.05% for 2025-2026, and Grad PLUS loans reach 8.05%. An $80,000 balance on a 15-year term reflects a common outcome for master's degree programs in fields like education, social work, public policy, and the humanities where starting salaries may not immediately support aggressive repayment. Understanding the interplay between rate, term, and repayment plan is essential for managing graduate-level debt effectively.

Key Considerations
- At 7.0% over 15 years, your monthly payment is $719 and total interest reaches $49,459 -- you repay $129,459 for an $80,000 loan, with interest exceeding 60% of the original principal.
- Switching to a 10-year term raises the payment to $929/month but slashes total interest to $31,449, a savings of $18,010 compared to the 15-year plan.
- If you work in public service, PSLF forgives remaining balance after 120 qualifying IDR payments. On a $55,000 salary, your SAVE payment would be roughly $185/month, and after 10 years of payments totaling approximately $22,200, the remaining $65,000+ balance is forgiven tax-free.
- Refinancing graduate loans from 7.0% to 5.0% over 10 years drops total interest from $49,459 to $21,859 and monthly payment from $719 to $849 -- a net savings of $27,600 but a higher monthly commitment.
- Graduate borrowers with both subsidized undergraduate and unsubsidized graduate loans should use the avalanche method, targeting the 7.0% graduate loans first while making minimums on 3.5-5.5% undergraduate loans.

How This Compares
Graduate school loans at 7.0% over 15 years cost $18,010 more in total interest than a 10-year term, but the lower $719 payment provides breathing room during early career years when master's-level salaries often start at $45,000-$55,000. Compared to the $100,000 tier, graduate borrowers face a lower rate spread but longer default terms, making the IDR-to-aggressive-payoff transition the defining strategy rather than immediate standard repayment.
Frequently Asked Questions
- When should graduate borrowers switch from IDR to standard repayment?
- Start on an income-driven plan during the first 3-5 years when your salary is below $60,000 and IDR payments of $185-$280 per month are manageable. Once your income exceeds $75,000-$80,000, switch to a 10-year standard or refinanced plan to attack the remaining balance aggressively. Delaying this transition beyond year 5 adds $10,000-$15,000 in unnecessary interest because graduate loan rates of 7.0%+ compound quickly on large balances.
- Is refinancing graduate school loans a good idea at 7.0%?
- Refinancing from 7.0% to 5.0% over 10 years saves $27,600 in total interest but raises your monthly payment from $719 to $849. This makes sense once you have 2-3 years of stable employment, a credit score above 740, and confirmed you will not pursue PSLF. Borrowers in social work, education, and public policy should retain federal loan status because their career paths often qualify for PSLF forgiveness that exceeds refinancing savings.
- How does PSLF work for graduate school borrowers with $80,000 in loans?
- Graduate borrowers working in qualifying public service roles make 120 IDR payments over 10 years, after which the remaining balance is forgiven tax-free. On a $55,000 salary, your SAVE payment would be roughly $185 per month, totaling approximately $22,200 in payments over 10 years. The remaining $65,000+ balance is forgiven, making PSLF the most powerful strategy for graduate borrowers in nonprofit, government, and public-sector roles.
