Worked Example
For a $25,000 loan at 4.5% annual interest for 5 years:
- Convert annual rate to monthly: 4.5% ÷ 12 = 0.375% or 0.00375
- Calculate number of payments: 5 × 12 = 60
- Plug into formula:
M = 25000 [ 0.00375(1 + 0.00375)^60 ] / [ (1 + 0.00375)^60 - 1 ]
- Monthly payment = $477.36
- Total interest paid = $7,481.60
- Total amount paid = $32,481.60
Types of Auto Loan Payments
Auto loan payments can be structured in several ways:
| Payment Type | Description | Example Use |
|---|---|---|
| Fixed Rate | Same monthly payment throughout loan term | Most conventional loans |
| Variable Rate | Payment changes with market interest rates | Some subprime or adjustable-rate loans |
| Balloon Payment | Small monthly payments with large final payment | Some lease-to-own arrangements |
| Interest-Only | Pay only interest for initial period | Some commercial or investment loans |
Fixed-rate loans are most common for auto purchases as they provide predictable payments and lower long-term interest costs.
