  3. 03Enter trade-in value: $3,000.
  4. 04Enter interest rate: 7.4%.

Car price you can afford: $22,007. Amount financed: $15,007. Loan payment: $300.00. Total interest: $2,993.

These figures come straight from the calculator above running on the values listed, so you can retype them and confirm every number yourself. Change any input and the results update immediately. Illustrative only — not a quote, offer or recommendation.

Important considerations

  • Insurance, fuel, tax and maintenance often add 30–50% to the payment.
  • Longer terms raise affordability but risk negative equity.
