What “Cap cost reduction” means
A cap cost reduction is anything that reduces the cap cost: cash, a manufacturer rebate, or positive equity from a trade-in. It lowers the payment because there is less to depreciate and less to charge rent on.
Paying cash down on a lease is mostly prepaying the lease. If the car is totaled or stolen, the lease’s GAP protection typically settles what you owe the leasing company, but your down payment generally isn’t refunded.
How it shows up at the dealership
Lease ads often advertise a low payment “with $3,999 due at signing,” most of which is a cap cost reduction. Dealers may suggest putting more down to hit a payment. Compare deals on total cost, or by converting everything to a $0-down payment.
Worked example · illustrative numbers, not a quote
$3,000 down on a 36-month lease (money factor 0.00180)
| Depreciation saved per month | $83.33 |
| Rent charge saved per month | $5.40 |
| Payment drops by | about $89/mo |
| If the car is totaled in month 3 | most of the $3,000 is gone |
Rebates applied as a cap cost reduction are different: take them, they’re not your cash.
What to do
- Aim for “first month and fees” at signing.
- If you want a lower payment, negotiate the price or pick a car with a better residual instead.
- If you have spare cash, ask whether the brand offers multiple security deposits, which are refundable.
What to say
“Please quote this with zero cap cost reduction: first month, fees and taxes only at signing. I’ll compare payments on that basis.”
Also called: lease down payment, capitalized cost reduction.
