New vs. Used Net Financial Impact Formula
Net Savings = (New Car Depreciation + Loan Interest + Insurance + Maintenance) โ (Used Car Depreciation + Loan Interest + Insurance + Maintenance)- Depreciation Advantage: Used cars have already absorbed the sharpest 30% to 40% initial value drop.
- Financing Differential: New cars often qualify for promotional manufacturer APRs (e.g. 2.9% to 5.5%), whereas used loans typically carry higher rates (7% to 10%).
- Insurance & Maintenance: New cars cost slightly more to insure but enjoy factory bumper-to-bumper warranty protection.
Step-by-Step Worked Example
Calculation Steps:
- New Car 5-Year Costs = $17,100 (depreciation) + $4,985 (interest) + $8,500 (insurance) + $3,000 (upkeep) = $33,585
- Used Car 5-Year Costs = $6,000 (depreciation) + $4,073 (interest) + $6,750 (insurance) + $5,500 (upkeep) = $22,323
- Net 5-Year Financial Savings with Used Car = $33,585 โ $22,323 = $11,262
