Formula Used

The calculation uses the standard auto loan payment formula:

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 months)

This formula accounts for the interest charged on the outstanding loan balance each month, providing an accurate estimate of your monthly payment.

Worked Example

Let's calculate a monthly payment for a $25,000 loan at 4.5% annual interest 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

Monthly interest rate = 4.5% / 12 = 0.375% or 0.00375

Number of payments = 60

Monthly payment = $25,000 [ 0.00375(1 + 0.00375)⁶⁰ ] / [ (1 + 0.00375)⁶⁰ - 1 ]

Calculated monthly payment = $452.34

This example shows that a $25,000 loan at 4.5% interest over 5 years would result in approximately $452.34 per month.
