New vs Used Car Calculator

Compare two vehicles — new and used — across monthly payment, interest, depreciation, and total ownership cost.

Estimate only. Estimate only. Not a loan offer, lender quote, dealer quote, lease agreement, retail installment sales contract, DMV estimate, or financial advice. Actual rates, payments, taxes, fees, incentives, residual values, insurance, fuel, and maintenance costs may vary.

How this is calculated

For each vehicle we compute monthly payment, interest, depreciation, and insurance/fuel/maintenance costs over your ownership horizon.
