Auto Leasing Economics: Using the Total Cost Lease Factor (GLF) for Objective Deal Analysis
When evaluating commercial vehicle fleet contracts or personal auto leases, focusing solely on base monthly payments often conceals substantial upfront acquisition and disposition fees. Calculating the Total Cost Lease Factor (GLF) standardizes all upfront fees across the contract term to deliver an accurate benchmark.
1. Foundational Lease Factor Equations
- Nominal Lease Factor:
(Monthly Lease Payment / MSRP List Price) × 100 - Effective Monthly Cost:
((Monthly Payment × Months) + Down Payment + Acquisition Fees) / Months - Total Cost Lease Factor (GLF):
(Effective Monthly Cost / MSRP List Price) × 100 - Cost per Driven Mile/km:
Total Contract Outlay / Total Contract Mileage
2. Actionable Guidelines for Fleet Managers
Secure optimal terms by evaluating offers based on the all-in GLF rather than promotional base rates, minimizing initial capital down payments to maintain liquidity, and aligning contract mileage allowances with actual historical driving patterns to avoid excess mileage penalties.
