What a lease actually pays for
When you lease, you don't pay for the whole car — only its depreciation during your term (the value it loses) plus a finance charge. That's why lease payments are lower than loan payments on the same car: you're financing perhaps $14,000 of value lost, not the full $35,000. At lease end you return the car (worth its "residual value") and walk away, or buy it for that residual.
Decoding the money factor
The money factor is the lease's interest rate in disguise. Convert it to a familiar APR by multiplying by 2,400: a 0.0025 money factor is roughly 6% APR. Dealers sometimes quote the money factor hoping you won't translate it — always convert and compare it to normal loan rates. A high money factor is expensive interest wearing an unfamiliar costume.
The residual value lever
A higher residual means the car keeps more value, so you pay for less depreciation and your payment drops. Cars that hold value well (strong resale reputations) often lease more cheaply than their price suggests, while fast-depreciating models lease expensively. The residual is set by the leasing company, not negotiable — but it explains why two similarly-priced cars can have very different lease payments.
Lease vs buy, briefly
- Leasing means lower payments, a new car every few years, and warranty coverage — but perpetual payments and no ownership, plus mileage limits and wear charges.
- Buying costs more monthly but ends in an owned asset and payment-free years, usually the cheaper path if you keep cars a long time.
This is an estimate; real leases add taxes, fees, and mileage terms. But knowing the depreciation and finance components — and converting that money factor to an APR — puts you far ahead of the average lessee at the dealership.
