What is Student Loan Calculator?

A student loan calculator helps you understand your repayment options and choose a strategy that fits your budget while minimizing total interest costs.

How It Works

Enter your total loans, average interest rate, and preferred term. The calculator shows your standard payment and lets you compare the impact of extra payments.

The Formula

M = P × [r(1+r)^n] / [(1+r)^n - 1]

Same as standard loan amortization. The calculator also shows the impact of extra payments on payoff time and total interest.

Examples

Example: $35,000 in student loans at 5.5%

Standard 10-year repayment with $100 extra monthly

The standard payment is $380/month. By paying $480/month ($100 extra), you clear the debt in 7.5 years (2.5 years early) and save $2,850 in interest.

Frequently Asked Questions

Should I choose standard or income-driven repayment?
Standard repayment pays off the loan fastest with the least interest. Income-driven plans (IBR, PAYE, REPAYE) cap payments at 10-20% of discretionary income and offer forgiveness after 20-25 years, but you'll pay more interest overall.
Can I pay off student loans early?
Yes, federal and private student loans generally allow early payoff without penalties. Extra payments should be applied to the highest-interest loan first for maximum savings.
What happens if I don't pay my student loans?
Defaulting on federal loans can lead to wage garnishment, tax refund seizure, and damaged credit. Federal loans have more flexible forgiveness options than private loans. Always contact your servicer if you're struggling.
Is student loan forgiveness real?
PSLF (Public Service Loan Forgiveness) is real for qualifying government/nonprofit employees after 120 qualifying payments. Income-driven forgiveness is also available after 20-25 years. However, tax implications may apply.
