Formula Explained

The calculator uses the standard auto loan payment formula:

Monthly Payment = P × (r(1 + r)^n) / ((1 + r)^n - 1)

Where:

P = Principal loan amount ($20,300)
r = Monthly interest rate (annual rate ÷ 12 ÷ 100)
n = Number of payments (loan term in years × 12)

This formula calculates the fixed monthly payment required to pay off the loan in the specified term, including both principal and interest.

Worked Example

Let's calculate a $20,300 auto loan with a 5% annual interest rate over 5 years:

Principal (P) = $20,300
Annual interest rate = 5% → Monthly rate (r) = 5% ÷ 12 ÷ 100 = 0.004167
Loan term = 5 years → Number of payments (n) = 5 × 12 = 60

Plugging these values into the formula:

Monthly Payment = $20,300 × (0.004167(1 + 0.004167)^60) / ((1 + 0.004167)^60 - 1)

Monthly Payment ≈ $364.23

Total interest paid over 5 years: $2,500.20

Frequently Asked Questions

What is the difference between APR and interest rate?

APR (Annual Percentage Rate) is the total cost of borrowing, including all fees and charges, while the interest rate is the actual percentage charged on the loan. APR is always higher than the interest rate.

How does a longer loan term affect my payments?

A longer loan term means lower monthly payments but more total interest paid. A shorter term results in higher monthly payments but less total interest.

Can I pay extra toward my loan?

Yes, paying extra principal can reduce your loan balance faster and save on interest. The calculator doesn't account for extra payments, but you can adjust the loan amount to reflect your extra payments.
