Formula Used
The USAA Auto Calculator uses the standard auto loan payment formula:
Monthly Payment = P × (r(1 + r)^n) / ((1 + r)^n - 1)
Where:
- P = Principal loan amount
- r = Monthly interest rate (Annual Rate / 12 / 100)
- n = Number of payments (Loan Term in Years × 12)
Total Interest Paid = (Monthly Payment × n) - P
Total Cost of Loan = Monthly Payment × n
Worked Example
Let's calculate a $25,000 loan at 4.5% annual interest for 5 years:
- Monthly interest rate = 4.5% / 12 / 100 = 0.00375
- Number of payments = 5 × 12 = 60
- Monthly Payment = $25,000 × (0.00375(1 + 0.00375)^60) / ((1 + 0.00375)^60 - 1) ≈ $452.38
- Total Interest Paid = ($452.38 × 60) - $25,000 ≈ $2,342.80
- Total Cost of Loan = $452.38 × 60 ≈ $27,142.80
This example shows that a $25,000 loan at 4.5% interest over 5 years would have a monthly payment of approximately $452.38, with $2,342.80 in total interest paid.
