Student Loan Payment Formula
Uses the standard amortization formula:
M = P × [r(1+r)^n] / [(1+r)^n - 1]
Federal student loans typically use a 10-year standard repayment plan.
Example Calculation
$35,000 in student loans at 5.5% over 10 years.
- 01Monthly rate = 5.5% / 12 = 0.4583%
- 02Payments = 10 × 12 = 120
- 03Monthly payment = $379.61
- 04Total repaid = $379.61 × 120 = $45,553
- 05Total interest = $45,553 - $35,000 = $10,553
