Student Loan Repayment Calculator

Enter your figures or complete the checklist. Results are planning estimates, not official decisions.

Student loans are a reality for millions of graduates worldwide. In the USA alone, total student debt exceeds $1.7 trillion. Understanding your monthly payment and total interest before borrowing helps you make smarter decisions about how much to borrow and which repayment plan to choose.

This Student Loan Repayment Calculator estimates your monthly payment and total interest using standard amortization. Enter your loan amount, interest rate, and repayment term to see what you'll actually pay over time.

How to use this calculator

  • Enter your loan amount — the total principal you plan to borrow.
  • Set the interest rate — US federal student loans are typically 5–8%; private loans vary widely.
  • Choose repayment term — standard is 10 years, but extended plans can go up to 25–30 years.

Estimate monthly loan payments (illustrative amortization).

Understanding your results

The calculator shows your estimated monthly payment and total interest paid over the life of the loan. A longer repayment term lowers monthly payments but increases total interest significantly. For example, a $40,000 loan at 6.5% costs about $11,600 in interest over 10 years, but over $26,000 in interest over 20 years.

Consider income-driven repayment plans (USA) or Plan 2/Plan 5 repayment thresholds (UK) which adjust payments based on earnings. Also explore loan forgiveness programs for qualifying public-service careers.

Frequently asked questions

The average US student loan payment is approximately $300–$500 per month, depending on the total borrowed and repayment plan. Graduates with professional degrees may pay $1,000+ monthly.

A longer term (20–25 years) reduces monthly payments but significantly increases total interest. If you can afford higher monthly payments, a 10-year standard plan saves thousands in interest. Use this calculator to compare different terms.

Student loan interest accrues daily on the outstanding principal balance. With standard amortization, early payments go mostly toward interest, and later payments go more toward principal. Making extra payments reduces total interest.
