Formula Used

The calculator uses the following formulas to estimate your trade-in value and financing:

Trade-In Value = (Original Price - Depreciation) × (1 - Mileage Penalty) Depreciation = Original Price × (Years Owned × Annual Depreciation Rate) Mileage Penalty = (Mileage / 120,000) × 0.2 Monthly Payment = [Loan Amount × (1 + (Interest Rate × Loan Term))] / (Loan Term × 12) Loan Amount = Vehicle Price - Down Payment - Trade-In Value Total Cost = (Vehicle Price - Down Payment - Trade-In Value) + (Monthly Payment × Loan Term) + Taxes + Fees

These formulas provide a reasonable estimate based on industry averages and CarMax's pricing policies.
