Borrowing $20,000 as a 4-year auto loan at 5.5% APR? Here is the complete payment breakdown — same formula your bank uses.
Monthly Payment: $465
This is your fixed monthly obligation. Each payment splits into principal (reducing your debt) and interest (the lender's fee). The interest share shrinks every month as your balance falls.
Principal vs. Interest Split
Total interest over 4 years: $2,326 | Total payable: $22,326
Tip: adding even $100 extra to each monthly payment on a 4-year loan can shave years off your term and save thousands in interest. Try the Extra Payment field in the calculator to model this.
