Formula Used
The calculator uses the standard auto loan payment formula:
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 divided by 12)
- n = Number of payments (loan term in years × 12)
Total Interest Paid = (Monthly Payment × n) - P
Worked Example
Let's calculate a $25,000 auto loan at 4.5% APR for 5 years:
| Input | Value |
|---|---|
| Loan Amount | $25,000 |
| Interest Rate | 4.5% |
| Loan Term | 5 years |
Monthly interest rate = 4.5% ÷ 12 = 0.375% or 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 ≈ $1,124.80
Note
Actual payments may vary slightly due to rounding and the exact interest rate offered by Summit Credit Union.
