Student Loan Calculator

Estimate fixed-rate student loan payment, total interest and payoff time.

Country and program rules matter

This page uses generic fixed-rate amortization. Real student loan programs may include subsidized interest, income-driven repayment, forgiveness rules, grace periods, deferment, tax treatment and country-specific protections. Use official loan servicer information for decisions.

Example

A 30,000 loan at 5% over 10 years gives an estimated fixed monthly payment of about 318 before any extra payment. Extra monthly payments can shorten payoff time and reduce interest.

Common mistakes

Do not assume every student loan is a standard amortizing loan. Some programs use income-based formulas, interest subsidies or forgiveness rules that change the calculation.

Limitations

This is not legal, tax or financial advice. It does not include fees, deferment, variable rates, official repayment-plan eligibility or country-specific protections.
