Formula Explained
The calculator uses the following formula to calculate your monthly auto loan 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 (APR/12)
- n = Number of payments (loan term in months)
This formula accounts for the interest on your loan balance each month, which is why the monthly payment remains constant throughout the life of the loan.
Worked Example
Let's look at an example to see how the calculator works. Suppose you're applying for a $25,000 auto loan with a 4.5% APR over 60 months (5 years).
| Input | Value |
|---|---|
| Loan Amount | $25,000 |
| Annual Interest Rate | 4.5% |
| Loan Term | 60 months |
Using the formula:
Calculation Steps
1. Convert APR to monthly rate: 4.5%/12 = 0.375% or 0.00375
2. Calculate the monthly payment using the formula
3. The result is approximately $452.38 per month
This means you would pay about $452.38 each month for 60 months, with a total interest of about $3,154. The payment chart in the calculator would show you how your loan balance decreases each month.
