How Auto Loan Calculations Work
Auto loan calculations use the standard loan amortization formula to determine monthly payments. The formula accounts for the principal amount, interest rate, and loan term.
Monthly Payment Formula
The monthly payment (PMT) is calculated using:
PMT = 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)
This formula assumes fixed monthly payments and a fixed interest rate. The calculator also provides the total interest paid and the total amount paid over the life of the loan.
Assumptions
- Fixed monthly payments
- Fixed interest rate
- No prepayment penalties
- No additional fees or taxes
Worked Example
Let's calculate an example auto loan:
- Loan amount: $25,000
- Annual interest rate: 4.5%
- Loan term: 5 years
Using the formula:
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]
Calculating this gives a monthly payment of approximately $452.38.
Over 5 years, you would pay:
- Total payments: $452.38 × 60 = $27,142.80
- Total interest: $27,142.80 - $25,000 = $2,142.80
| Payment Number | Principal | Interest | Balance |
|---|---|---|---|
| 1 | $427.50 | $24.88 | $24,572.50 |
| 2 | $427.92 | $24.46 | $24,144.58 |
| 3 | $428.34 | $24.04 | $23,716.24 |
| 4 | $428.76 | $23.62 | $23,287.48 |
| 5 | $429.18 | $23.20 | $22,858.30 |
This table shows the first five payments of the loan, demonstrating how the principal and interest portions change over time.
