Cap Cost Reduction

What is a cap cost reduction on a lease?

A cap cost reduction is cash, a trade-in credit, or a manufacturer incentive applied at signing to lower the capitalized cost, the number your lease payment is built from. It is the technical, contract-language term for what most people simply call money down on a lease. The capitalized cost sits close to the negotiated selling price of the car, so reducing it means financing less of the car for less time.

A cap cost reduction is optional on nearly every lease. Skip it, and the leasing company spreads the full capitalized cost across your monthly payments instead. Add it, and the payment drops, because less money sits in the deal earning depreciation charge and rent charge each month.

How much does a cap cost reduction actually lower your payment?

On a hypothetical $29,500 lease, a $1,500 cap cost reduction drops the base payment by $45.56 a month, but the real saving over the full term is only about $140, because most of what it buys is a smaller finance charge, not a real reduction in what the car costs. Here is the math, computed rather than estimated, on a hypothetical 36-month lease: a $32,000 MSRP car, a $29,500 negotiated selling price, a 57% residual, and a 0.00260 money factor (about 6.24% APR).

Add the $1,500 back into the reduced-payment total: $14,088 plus $1,500 equals $15,588. Compare that to the no-down total of $15,728, and the actual saving is about $140, the finance charge difference. The rest of the payment drop is money you already paid, just moved earlier in the deal instead of spread across it.

Where does a cap cost reduction fit in what's due at signing?

It is one of several pieces due at signing, and the only one that is optional. Due at signing on most leases bundles the first month's payment, an acquisition fee, documentation and title charges, and any cap cost reduction you choose to add. The first three are set by the lease and your state; the cap cost reduction is the only piece you control, since it is extra money you choose to add rather than a fee you owe.

Skipping it does not mean nothing is due. A "zero down" lease usually still has a first payment, an acquisition fee, and title costs to collect at the counter, since zero down only means zero cap cost reduction. For the full breakdown of what is due at signing and how "zero down" differs from "zero due at signing," see what fees are due at signing on a lease.

If you want a lever that lowers your payment without spending money at signing, multiple security deposits (MSDs) are a refundable alternative some captives offer. An MSD lowers the money factor instead of the cap cost, and unlike a cap cost reduction, it is typically returned at lease end. See what are multiple security deposits for how that trade works.

How is a cap cost reduction different from a down payment on a loan?

It does not build ownership equity, which is the difference that matters most. A down payment on a loan reduces the principal on a car you are going to own, so every dollar goes toward equity starting on day one. A cap cost reduction only lowers the capitalized cost your lease payment is calculated from, on a car you hand back at the end of the term, commonly 36 months. It never sits behind the deal as your stake in the car.

That gap matters most if the car is stolen or totaled early in the lease. A cap cost reduction is not a refundable deposit, so that money is typically gone. It already reduced the payoff the leasing company calculates, and there is no separate pot left to return once the car is gone. GAP coverage, where it applies, protects you from owing extra on that payoff, not from losing what you put down.
