How Auto Loan Calculations Work
Auto loan calculations are based on the loan amount, interest rate, and loan term. The calculator uses the standard amortization formula to determine your monthly payment:
Monthly Payment Formula
M = P [ i(1 + i)n ] / [ (1 + i)n - 1 ]
Where:
- M = Monthly payment
- P = Principal loan amount
- i = Monthly interest rate (annual rate divided by 12)
- n = Number of payments (loan term in years multiplied by 12)
The calculator also calculates the total interest paid by subtracting the original loan amount from the total amount paid.
Assumptions
- This calculator assumes a fixed interest rate for the entire loan term.
- It does not account for prepayment penalties or changes in interest rates.
- Results are estimates and may vary based on actual loan terms.
Example Calculation
Let's look at an example to see how the auto loan calculator works. Suppose you're financing a $25,000 car with a 4.5% annual interest rate over 5 years (60 months).
| Input | Value |
|---|---|
| Loan Amount | $25,000 |
| Interest Rate | 4.5% |
| Loan Term | 5 years |
Using the formula:
Calculation Steps
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 ]
Monthly payment ≈ $456.23
Total amount paid over 5 years would be $456.23 × 60 = $27,373.80, with $2,373.80 going toward interest.
