How auto loan payments are calculated

Educational guide · Updated · About 7 min read

An auto loan payment is usually a fixed monthly installment that pays interest and principal so the loan balance reaches zero by the end of the term—if rates and payments stay as modeled.

Two steps

  1. Amount financed — price, optional tax/fees you type, minus down payment and trade-in.
  2. Amortization — standard fixed-rate payment formula using that principal, your sample APR, and term in months.

Sample

$30,000.00 vehicle · $3,000.00 down · 7% · 60 months → financed about $27,000.00, payment about $534.63. Open sample
