How Auto Payments with Extra Payments Work
When you make extra payments on your auto loan, you're essentially paying off a portion of the loan principal earlier than scheduled. This reduces the total interest you'll pay over the life of the loan and allows you to pay off the loan faster.
The calculator uses the following formula to determine your new monthly payment:
Monthly Payment = P * (r(1+r)^n) / ((1+r)^n - 1)
Where:
- P = Principal loan amount
- r = Monthly interest rate (annual rate divided by 12)
- n = Number of payments (loan term in years multiplied by 12)
When you make extra payments, the principal balance decreases more quickly, which reduces the total interest paid. The calculator also shows how much interest you'll save by making extra payments.
Example Calculation
Let's say you have a $20,000 auto loan with a 5% annual interest rate and a 4-year term. Your regular monthly payment would be approximately $462.67. If you make an extra payment of $200 each month, your new monthly payment would be $662.67, and you would pay off the loan in about 3 years and 3 months, saving $1,200 in interest.
Making extra payments can significantly reduce your loan term and interest costs, but it may require a higher monthly payment. Always consider your budget before making extra payments.
