The mathematical break-even occurs when annual mileage exceeds 18,500 miles or fuel costs rise above $0.35 per mile. While the ICE vehicle has zero monthly payments, the EV lease leverages a Guaranteed Future Value to hedge against battery degradation. Most users find the ICE path cheaper for 36 months, with EV operational savings scaling only after year 4.
Initial deposit, registration fees, and lease acquisition costs.
Annual lease payments combined with charging costs.
Cumulative lease payments; GFV removes depreciation risk.
Total cost of ownership over two lease cycles or buyout.
No monthly payments or upfront capital outlay.
Fuel costs and routine oil/filter changes.
Increased maintenance frequency and fuel inefficiency.
Total fuel/repair spend minus the residual salvage value.
Toggle high-probability external shocks to see how fragility surfaces in each path.
Global oil supply shock increases fuel costs by 40%.
Solid-state batteries make current EV leases obsolete.
Peak-hour charging surcharges increase electricity costs.
| Decision Dimension | Path A: EV Lease (GFV) | Path B: Keep Paid-off ICE | Consequence Edge |
|---|---|---|---|
| Monthly Cash Flow | High (Lease Pmts) | Low (Fuel Only) | Path B |
| Depreciation Risk | Low (GFV Hedge) | High (Market Value) | Path A |
| Environmental Impact | Lower (Tailpipe 0) | Higher (CO2) | Path A |
| Equity Position | Zero/Low | Asset Retained | Path B |

Guaranteed Future Value is a contractually agreed minimum value of the car at the end of the lease, shielding the user from battery degradation value drops.
Typically when annual mileage exceeds 18,000-20,000 miles, the fuel savings ($0.12+ per mile) offset the monthly lease payment (~$500/mo).
No. If the ICE vehicle requires a major repair (e.g., $3,000 transmission) or fuel prices spike, the predictable cost of a lease becomes mathematically superior.
