Understanding Lexus Total Cost of Ownership
When investing in a luxury vehicle, the "Lexus Calculator" approach focuses on two primary pillars: reliability and value retention. Unlike many European luxury brands that see sharp drops in value after the warranty expires, Lexus consistently ranks at the top of the Kelley Blue Book Resale Value Awards.
Depreciation and Resale Factors
Lexus vehicles typically retain between 45% and 60% of their value after five years of ownership. SUV models like the Lexus RX and GX tend to hold their value significantly better than high-performance coupes. Our calculator uses a specific decay algorithm based on model categories to project what your vehicle will be worth when you are ready to trade it in.
Maintenance and Service Intervals
Lexus maintenance is generally more affordable than its competitors because it shares a supply chain with Toyota. Standard maintenance logic follows a 5,000-mile or 6-month cycle.
Minor Service: Oil changes, tire rotations, and fluid checks.
Major Service: Every 30,000 miles, including brake fluid replacement and cabin filters.
Long-term Reliability: Lexus engines are famous for reaching 200,000+ miles with only routine fluid changes.
Example Analysis
If you purchase a Lexus RX for $60,000 and drive it for 5 years at 15,000 miles per year, the calculator accounts for approximately $4,500 in total maintenance and a residual value of roughly $35,000. This brings your real-world cost of ownership (excluding fuel and insurance) to about $0.39 per mile, one of the lowest in the luxury segment.
