To use the auto loan calculator with additional payment feature:

How Additional Payments Work

When you make additional payments on your auto loan, you're essentially paying off a portion of the principal balance. This reduces the total interest you'll pay over the life of the loan because you're paying down the principal faster.

Formula for Monthly Payment:

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)

By making additional payments, you'll see a reduction in both the total interest paid and the number of months required to pay off the loan.

Example Calculation

Let's say you have an auto loan with the following details:

  • Loan Amount: $20,000
  • Interest Rate: 5% APR
  • Loan Term: 5 years
  • Regular Monthly Payment: $350
  • Additional Monthly Payment: $100

Using the calculator, you'll find that:

  • Your new monthly payment will be $450.
  • You'll pay off the loan in 48 months instead of 60 months.
  • You'll save $500 in interest by making the additional payments.

Making additional payments on your auto loan can help you save money and pay off your debt faster. However, be sure to check with your lender to see if they allow additional payments and if there are any fees associated with making extra payments.
