Formula Used

The auto loan calculator uses the standard auto loan payment formula:

This formula calculates the fixed monthly payment required to pay off a loan with a fixed interest rate over a specified period.

Worked Example

Let's say you're buying a car for $25,000 with a 4.5% annual interest rate and a 5-year loan term. Here's how the calculation works:

1. Principal (P) = $25,000
2. Annual interest rate = 4.5% or 0.045
3. Monthly interest rate (i) = 0.045 / 12 ≈ 0.00375
4. Loan term in months (n) = 5 years × 12 = 60 months

Plugging these values into the formula:

So your estimated monthly payment would be $452.36. Over 5 years, you would pay a total of $11,744.60 in interest, making the total cost of the loan $36,744.60.
