Car Loan Calculator

  • Browser-based
  • No signup

Enter vehicle price, down payment, interest rate, and loan term in months. Optionally include trade-in value and sales tax to estimate the amount financed, monthly payment, total interest, and total cost.

Dealers and credit unions quote payments using the same amortization math this calculator uses, but they may roll tax, documentation fees, or optional products into the amount financed. Use this page to compare term length and down payment before you negotiate—not as a binding payment promise.

If you are deciding between a rebate and a low APR promotion, run both scenarios with the same vehicle price and down payment. A higher monthly payment on a shorter term often saves thousands in total interest even when the promotional rate looks attractive on a longer loan.

What to do next

How to use this tool

1. Enter vehicle price, down payment, APR, and loan term in months. 2. Add optional sales tax percent and trade-in value if they apply. 3. Click Calculate. 4. Review monthly payment, total interest, and total cost. 5. Adjust down payment or term to compare scenarios—figures exclude dealer fees, insurance, and registration unless you add them separately.

Worked example

Example: a mid-range vehicle near $35,000 with about $5,000 down, roughly 6–7% APR, and a 60-month term often produces a payment in the mid-$500s per month on the financed balance before taxes and fees—your lender’s quote may differ.

When to use this

  • Comparing monthly payments before visiting a dealer or lender.
  • Seeing how a larger down payment or shorter term changes total interest.
  • Rough budgeting when you know vehicle price, APR, and trade-in value.
  • Checking whether a promotional 0% offer beats a cash rebate plus financed balance.

Common examples

  • $25,000 vehicle with $3,000 down, 6.9% APR, 60 months → about $435/month on $22,000 financed (before tax, title, and dealer fees).
  • $35,000 SUV with $5,000 down, 7.2% APR, 72 months → about $514/month on $30,000 financed—lower payment than 60 months but roughly $1,400 more total interest.
  • $45,000 truck with $8,000 down plus a $6,000 trade-in, 5.9% APR, 48 months → about $727/month on $31,000 financed for a shorter payoff window.
  • $42,000 SUV with $7,000 down, 5.4% APR, 48 months → about $815/month before tax on roughly $35,000 financed.
  • Used $18,500 sedan with $2,000 down, 8.9% APR, 36 months → higher payment but less total interest than 72 months at the same rate.

Common mistakes

  • Entering APR as 6 instead of 6.9 when the lender quotes an annual rate.
  • Forgetting sales tax is often financed on top of the negotiated price.
  • Comparing a 72-month payment to a 48-month quote without looking at total interest.
  • Treating the estimate as a firm lender approval amount.

How it works

Enter the vehicle price, down payment, interest rate, and loan term in months. Optional trade-in value and sales tax are applied to estimate the amount financed. The calculator uses the standard amortizing loan formula for monthly payment, total interest, and total cost. Fees, insurance, and registration beyond your inputs are not included.

Limitations

Estimates assume a fixed APR and equal monthly payments. Dealer fees, gap insurance, and regional tax rules are not included. Confirm final terms with your lender.

The calculator uses the standard amortizing loan formula based on the amount financed, monthly interest rate, and term in months.

Does this include fees or insurance?
