Formula Used
The monthly payment for an auto loan is calculated using the following 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)
This formula accounts for the interest on the loan balance over the term of the loan, providing an accurate estimate of your monthly payments.
Worked Example
Let's calculate a monthly payment for a $25,000 loan with a 4.5% annual interest rate over 5 years.
- Principal (P) = $25,000
- Annual interest rate = 4.5% or 0.045
- Monthly interest rate (i) = 0.045 / 12 = 0.00375
- Loan term in months (n) = 5 * 12 = 60
Plugging these values into the formula:
M = 25000 [ 0.00375(1 + 0.00375)60 ] / [ (1 + 0.00375)60 - 1 ]
M ≈ $452.34
So, the estimated monthly payment for this loan would be $452.34.
Understanding Your Results

Loan Amortization Schedule
The loan amortization schedule shows how your loan balance is paid off over time. The chart in the calculator visualizes this schedule, showing the principal and interest portions of each payment.
Understanding your amortization schedule helps you see how quickly you're paying down the principal balance and how much interest you're paying each month.
