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.

Common examples

  • $25,000 vehicle with $3,000 down, 6.9% APR, 60 months → about $436/month on the financed balance (before sales tax and fees).
  • $35,000 vehicle with $5,000 down, 7.2% APR, 72 months → about $483/month with more total interest than a 60-month term.
  • $45,000 vehicle with $8,000 down plus a $6,000 trade-in, 5.9% APR, 48 months → about $745/month on roughly $31,000 financed.

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.
