Master’s Tip
How to use the result well
Master’s Tip: even small extra payments can shorten the final months because they attack principal after required interest is covered.

Explain it like I'm 12
The student loan repayment calculator applies standard amortising-loan mathematics and then tests the effect of any extra monthly payment on payoff time and interest.
Base payment = P × r ÷ (1 − (1 + r)^−n). Total monthly payment = base payment + extra payment. Balance is reduced month by month until paid off.
Worked example
$32,000 over 10 years at 5.5% gives a base payment around $347/month before any extra payment.

Methodology & Accuracy
How this calculator is checked
CalculationTime pages are built around visible arithmetic: the formula, assumptions, worked example and practical limitations are shown so the result can be checked rather than simply trusted.
Formula used
Base payment = P × r ÷ (1 − (1 + r)^−n). Total monthly payment = base payment + extra payment. Balance is reduced month by month until paid off.
Standard or basis
General amortising education-loan estimate. Local student-loan programs can use different statutory repayment rules.
Where a calculator follows a named legal, trade or industry standard, that standard is cited visibly. Otherwise the page uses transparent general arithmetic and states its limits.
