Guide
Buying a car is about more than just the monthly payment. You must consider insurance, fuel, maintenance, registration fees, and interest on the loan. A good guideline is the 20/4/10 rule: 20% down, a 4-year term, and keeping total auto costs under 10% of gross income.
This calculator helps you back into a purchase price based on what you can afford to pay monthly, ensuring you do not buy a car that stresses your monthly budget.
Gas and insurance can add hundreds of dollars to your monthly auto budget. Maintenance and depreciation also erode the value of your asset. Keeping auto costs conservative leaves room for other financial goals.
Car depreciation
The decline in a vehicle’s value over time, occurring most rapidly in the first few years.
Down payment
An initial payment made when something is bought on credit, reducing the total amount financed.
A guideline suggesting a down payment of at least 20%, financing for no more than 4 years, and keeping total monthly transportation costs under 10% of gross income.
Yes, a larger down payment reduces the principal loan amount, which lowers monthly payments and saves total interest over the life of the loan.
