Formula Used
The monthly payment for an auto loan is calculated using the standard 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)
- n = Number of payments (loan term in years × 12)
Total interest paid is calculated by subtracting the original loan amount from the total of all monthly payments.
Worked Example
Let's calculate a monthly payment for a $25,000 loan at 4.5% annual interest over 5 years (60 months).
- Convert annual interest rate to monthly: 4.5% ÷ 12 = 0.375% or 0.00375
- Plug values into the formula:
Monthly Payment = $25,000 × [0.00375(1 + 0.00375)60] / [(1 + 0.00375)60 - 1]
- Calculate the result: $25,000 × [0.00375 × 1.231] / [1.231 - 1] = $25,000 × 0.463 / 0.231 ≈ $482.08
Total interest paid over 5 years would be $25,000 × 0.231 ≈ $5,775.
Loan Term Comparison
Compare how different loan terms affect your monthly payments and total interest costs.
| Loan Term | Monthly Payment | Total Interest |
|---|---|---|
| 36 months | $425.12 | $4,125 |
| 48 months | $382.45 | $5,250 |
| 60 months | $342.08 | $6,125 |
| 72 months | $312.50 | $7,050 |
Shorter loan terms result in higher monthly payments but lower total interest costs. Longer terms offer lower monthly payments but higher total interest.
