Como usar student calculator
- 01Enter your total balance
Use the current principal. If you have multiple loans at similar rates, add them together for a quick weighted estimate.
- 02Enter the rate
Federal unsubsidized graduate loans often run 6–8%. Private loans vary widely. If you have multiple rates, use the weighted average.
- 03Pick the repayment term
Standard is 10 years. Extended plans go 20–25 years and lower the monthly payment but balloon total interest.
- 04Try extra payments
Any extra — even $50/month — goes straight to principal. See how fast it pays the loan off and how much interest it erases.
Exemplos
Fórmula
Monthly payment = P × r / (1 − (1 + r)⁻ⁿ), where P is principal, r is the monthly interest rate (APR / 12), and n is the number of months. Extra payments are applied to principal each month until the balance reaches zero.
M = P · r / (1 − (1 + r)^−n)Perguntas frequentes
Should I extend the term to lower my payment?
Extending the term lowers the monthly payment but increases total interest, sometimes dramatically. Compare the two here before committing — a 10-to-20 year extension on a $35k loan can double the interest paid.
How much does income-driven repayment change the math?
Income-driven plans cap your payment at a percentage of discretionary income, which isn't what this calculator computes. Use this tool for standard and extended plans, then check your federal servicer for income-driven estimates.
Is it better to pay off student loans or invest?
If your rate is higher than your expected long-term investment return (often ~7%), extra payments usually win. Use this calculator with the compound-interest tool side by side to compare.
Does refinancing help?
Refinancing private loans to a lower rate can save real money — run your current and refinanced rates through this calculator to see the difference. Think carefully before refinancing federal loans, since you'll lose access to federal protections.
