Paying extra on your car payment usually goes toward the loan's principal, reducing the total interest you pay and shortening the loan term, but you must ensure your lender applies it as a principal-only payment, not as prepayment for next month, and check for any prepayment penalties. This saves money and helps you own the car sooner, though it won't lower your regular monthly payment amount unless you refinance.

What is the 50 30 20 rule for car payments?

The 50/30/20 rule is a simple budget guideline: 50% of your after-tax income for needs (like housing, groceries, and car payments/expenses), 30% for wants (dining out, entertainment), and 20% for savings and debt repayment. For a car payment, this means your total monthly car expenses (loan, insurance, gas, maintenance) should ideally fit within the 50% "Needs" category, with some experts suggesting car costs shouldn't exceed 10-15% of your income overall, making a modest car a "need" and luxury vehicles a "want".
