Formula Used

The auto loan payment calculator uses 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 divided by 12)
n = Number of payments (loan term in years multiplied by 12)

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 calculate the monthly payment for a $20,000 car loan with a 4.5% annual interest rate over 5 years.

Principal (P) = $20,000
Annual interest rate = 4.5% or 0.045
Monthly interest rate (r) = 0.045 / 12 ≈ 0.0037917
Loan term in months (n) = 5 × 12 = 60

Plugging these values into the formula:

Monthly Payment = $20,000 × (0.0037917(1 + 0.0037917)^60) / ((1 + 0.0037917)^60 - 1)

Monthly Payment ≈ $20,000 × (0.0037917 × 1.2314) / (1.2314 - 1)

Monthly Payment ≈ $20,000 × (0.00468) / 0.2314

Monthly Payment ≈ $20,000 × 0.0202

Monthly Payment ≈ $404.00

So, the monthly payment for this loan would be approximately $404.00.
