How Student Loan Calculations Work
Student loans are typically fixed-rate loans with a repayment term of 10 or 15 years. The calculator uses the standard loan amortization formula to determine your monthly payments and total interest.
Loan Amortization Formula
The monthly payment (P) is calculated using the formula:
P = L × (r(1 + r)^n) / ((1 + r)^n - 1)
Where:
- L = Loan amount
- r = Monthly interest rate (annual rate ÷ 12)
- n = Number of payments (loan term in years × 12)
The calculator also provides a repayment schedule that shows how much of each payment goes toward interest and principal over time.
Worked Example
Let's say you have a $20,000 student loan with a 5% annual interest rate and a 15-year repayment term.
| Input | Value |
|---|---|
| Loan Amount | $20,000 |
| Annual Interest Rate | 5% |
| Loan Term | 15 years |
The calculator would determine that your monthly payment would be approximately $162.50, with a total interest paid of $11,250 over the 15-year term.
Frequently Asked Questions
How does a 15-year student loan compare to a 10-year loan?
A 15-year loan typically has lower monthly payments but results in paying more in total interest over the life of the loan. A 10-year loan has higher monthly payments but pays less in total interest.
Can I refinance my student loan to a 15-year term?
Yes, you can refinance your student loan to a 15-year term if you qualify for a lower interest rate. This can reduce your monthly payments and total interest paid.
What happens if I can't make my student loan payments?
If you can't make your payments, contact your loan servicer immediately. They may offer deferment, forbearance, or other options to help you manage your payments.
Are student loans included in bankruptcy?
Student loans are not discharged in bankruptcy unless you meet specific criteria, such as having an extreme hardship or meeting the means test.
