Formula Used in the Student Loan Calculator
The monthly payment for a student loan is calculated using the amortization formula:
Monthly Payment (M) = P × [ r(1 + r)^n ] / [ (1 + r)^n – 1 ]
Where:
- P = Loan amount (principal)
- r = Monthly interest rate (annual interest rate ÷ 12)
- n = Total number of monthly payments (years × 12)
Total Interest Paid = (Monthly Payment × Number of Months) – Principal
Total Repayment Amount = Principal + Total Interest
Example Calculation
Let’s say you borrow $35,000 at a 5% annual interest rate for 10 years:
- Loan amount (P) = $35,000
- Annual interest rate = 5% → Monthly rate = 0.05 ÷ 12 = 0.004167
- Loan term = 10 years → Total payments (n) = 10 × 12 = 120
Monthly Payment = 35,000 × [ 0.004167 × (1 + 0.004167)^120 ] / [ (1 + 0.004167)^120 – 1 ]
Monthly Payment ≈ $371.23
- Total repayment = $371.23 × 120 = $44,547.60
- Total interest = $44,547.60 – $35,000 = $9,547.60
Result: You will pay about $371.23 per month, with $9,547.60 going towards interest over 10 years.
