What else moves your Lexus GX 550 Premium cost
The 5-year total already folds in depreciation, fuel, insurance, maintenance and financing. These are the levers that actually move money on this car, biggest first — each figure re-run through the same kernel with one input changed. Levers that don't move $400+ here aren't listed.
- Financing. The total finances $63,285 of the $66,285 price at 7.0% over 60 months: $11,902 of pure interest, 18% of everything above. Paying cash or shopping the rate removes it outright — both are inputs in the calculator.
- Efficiency. 17 mpg puts the Lexus GX 550 Premium below the 24 mpg median of the non-electric models we price — $3,960 more fuel over 5 years than a median car at the same pump price.
- Fuel price. The total runs on the U.S. average $3.85/gal. Add a dollar to the pump price and this car's 5-year total rises $3,529 to $69,606 — at 17 mpg and 12,000 mi/yr, fuel is the lever your own driving moves most.
- Depreciation curve. We cost the Lexus GX 550 Premium on its own residual curve, not the gas car average: it holds 66% of its $66,285 after 5 years against 61% for a typical gas car. That is about $3,314 less depreciation than the class curve would give it — and depreciation is $22,537 of the $66,077 above (34%).
