The break-even point between leasing and buying typically occurs at month 42. Leasing preserves liquidity but incurs a permanent 15-25% premium via money factors. Buying reduces long-term monthly spend by 40% after year 4, provided the asset retains at least 35% of its original value, making Buy & Hold superior for high-mileage, long-term users.
Down payment and acquisition fees. Capital remains largely liquid.
Monthly payments based on depreciation and money factor.
Lease ends; you have no asset equity to roll into the next vehicle.
Total spent over two lease cycles with zero asset retention.
Full purchase price or heavy down payment reduces liquid cash.
Foregone gains from investing the capital plus maintenance.
Warranty expires; maintenance costs begin to climb linearly.
Total opportunity cost minus the residual resale value of the car.
Toggle high-probability external shocks to see how fragility surfaces in each path.
Used car values plummet by 30% due to economic recession.
A breakthrough in battery/engine tech makes current models obsolete.
Central banks raise rates, increasing the cost of new financing/leases.
| Decision Dimension | Path A: The Lease Strategy | Path B: The Buy & Hold Strategy | Consequence Edge |
|---|---|---|---|
| Cash Liquidity | High (Preserves Capital) | Low (Ties up Capital) | Path A |
| Net Worth (5yr) | Negative (Pure Expense) | Positive (Asset Retained) | Path B |
| Tech Obsolescence | Low Risk (3-year cycles) | High Risk (Hold for 5+ years) | Path A |
| Monthly Budget | Stable/Predictable | Variable (Maintenance spikes) | Path A |

The money factor is the lease version of an interest rate. Multiply it by 2400 to get the equivalent APR (e.g., 0.0025 * 2400 = 6% APR).
Leasing is cheaper only if the user's internal rate of return (var_2) on the saved capital significantly exceeds the lease's implicit interest and depreciation cost.
High mileage (20k+/year) destroys Buy & Hold equity faster but triggers expensive penalties in leasing, making ownership the safer mathematical bet for heavy users.
