Formula Explained

The auto loan calculator uses the standard mortgage payment formula to calculate your monthly payments:

Monthly Payment Formula

M = P [ i(1 + i)n ] / [ (1 + i)n - 1 ]

Where:

  • M = Monthly payment
  • P = Principal loan amount ($28,000)
  • i = Monthly interest rate (annual rate divided by 12)
  • n = Number of payments (loan term in years × 12)

This formula accounts for the interest on the unpaid balance of your loan each month, which is why your monthly payment remains the same throughout the life of the loan.

Worked Example

Let's walk through an example calculation for a $28,000 auto loan with a 5.5% APR over 5 years:

  1. Convert the annual interest rate to a monthly rate: 5.5% ÷ 12 = 0.4583% or 0.004583 in decimal form.
  2. Calculate the number of payments: 5 years × 12 = 60 payments.
  3. Plug the values into the formula:

    M = $28,000 [ 0.004583(1 + 0.004583)60 ] / [ (1 + 0.004583)60 - 1 ]

  4. The calculation results in a monthly payment of approximately $524.36.

Over the 5-year term, you would pay a total of $31,461.60, with $3,461.60 going toward interest.

Frequently Asked Questions

What is the difference between APR and APY?

APR (Annual Percentage Rate) is the simple annual interest rate charged on a loan, while APY (Annual Percentage Yield) is the effective annual rate that takes into account compounding interest. APY is generally higher than APR for the same loan.

How does a longer loan term affect my monthly payments?

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

Can I pay extra toward my auto loan?

Yes, paying extra toward your auto loan can save you money on interest. Each additional payment reduces the principal balance faster, lowering the total interest paid over the life of the loan.
