Analytical Proof & Invariants

Machine Precision
Governing Mathematical Formula:
5-Yr TCO = Depreciation + Financing + Insurance + Fuel + Maintenance + Taxes/Fees

Step-by-Step Mathematical Derivation

1
Six Pillars of Vehicle Cost Breakdown

TCO = 1) Depreciation (typically 60% drop in 5 yrs) + 2) Fuel (60 mo) + 3) Insurance (60 mo) + 4) Financing Interest + 5) Maintenance & Repairs ($1,000/yr) + 6) Registration/Fees ($300/yr).

2
Hidden Depreciation Primacy

Depreciation is the single largest hidden expense of vehicle ownership, frequently exceeding fuel and insurance combined.

3
Per-Mile Amortization Metric

Total 5-year miles = 5 × 13,500 = 67,500 miles. Cost per Mile = TCO / 67,500.
