⚠️ Important: Refinancing federal loans into private loans removes IBR, SAVE, and forgiveness protections. Only refinance if you have stable income and won't need these.

Frequently Asked Questions
Using the amortization formula: M = P × [r(1+r)ⁿ] ÷ [(1+r)ⁿ − 1] where P = principal, r = monthly rate (annual ÷ 12), n = total payments. For a $30,000 loan at 6.39% over 10 years = $334/month and $10,081 in total interest.
For 2025–2026: Undergraduate Direct Subsidized & Unsubsidized: 6.39% · Graduate Unsubsidized: 7.94% · PLUS loans: 8.94%. Private student loan rates range from approximately 4% to 15% depending on credit score, income, and lender.
Select IBR or SAVE from the loan type dropdown and enter your annual income and family size. IBR caps your payment at 10% of discretionary income (income above 150% of the federal poverty guideline). SAVE used 5% of income above 225% — but was ended by a court order in March 2026. After 20–25 years of qualifying payments, any remaining balance may be forgiven.
Switch to UK mode (🇬🇧 at the top), select your repayment plan, and enter your annual salary before tax. Plan 2 (2012–2023 graduates): repay 9% of income above £27,295/year, written off after 30 years. Plan 5 (from Aug 2023): 9% above £25,000/year, written off after 40 years.
Subsidized: the government pays your interest while you're in school (half-time+), during the grace period, and during deferment. Unsubsidized: interest compounds monthly from disbursement — after 4 years plus a 6-month grace period, it capitalizes. Use the Sub vs Unsub tab to see the exact dollar difference.
Standard federal plan: 10 years. Extended: up to 25 years. Income-driven plans: 20–25 years. Making extra monthly payments significantly shortens the payoff time. Use the Extra Monthly Payment field to see exactly how many months sooner you can be debt-free and how much interest you save.
Click the Multiple Loans tab above. Enter each loan's balance, interest rate, and term. The calculator shows your combined monthly payment, total interest across all loans, and the weighted average rate.

How the Student Loan Payment Calculator Works
This student loan payment calculator uses the standard amortization formula: M = P × [r(1+r)ⁿ] ÷ [(1+r)ⁿ − 1], where P = principal (loan amount), r = monthly interest rate (annual rate ÷ 12), and n = total number of monthly payments (years × 12).
For example: a $30,000 loan at 6.39% over 10 years = $334/month, with $10,081 in total interest paid. A $50,000 loan at the same rate over 10 years = $557/month, with $16,801 in total interest.
Student Loan Payoff Calculator — How Extra Payments Help
Enter any amount in the Extra Monthly Payment field to instantly see how many months earlier you pay off the loan and how much total interest you save.
$50 extra/month on a $30,000 loan at 6.39% over 10 years saves ~$1,154 in interest and pays off 11 months early.
$100 extra/month saves ~$2,109 and pays off 19 months early.
$200 extra/month saves ~$3,620 and pays off 33 months early.
