"In a car lease, you're paying for the part of the car you use — not the part you'll sell."
-- Automotive Finance Principle
How car lease payments are calculated
A lease payment has three components: depreciation, finance charge, and tax.
The depreciation component is (Adjusted Cap Cost − Residual Value) ÷ Lease Term. You're paying for the value the car loses during the lease, not the full vehicle price.
The finance component is (Adjusted Cap Cost + Residual Value) × Money Factor. The money factor is the leasing equivalent of an interest rate -- multiply it by 2,400 to convert to an approximate APR.
The adjusted cap cost is the negotiated price plus any fees rolled in (like the acquisition fee), minus any cap cost reduction (down payment, trade-in, or manufacturer rebate). Negotiating the cap cost down is the single most effective way to lower your payment.
Residual value is set by the lender and is not negotiable. A higher residual means lower depreciation and a lower payment -- vehicles that hold their value well (like certain Japanese and German brands) tend to have favorable residuals.
lightbulb Example Lease Scenario
A vehicle has an MSRP of $35,000, negotiated to $33,000. The lender sets a 55% residual ($19,250) and a money factor of 0.00125 (equivalent to ~3% APR). Term: 36 months.
With a $795 acquisition fee rolled in and no cap reduction, the adjusted cap cost is $33,795. Depreciation = ($33,795 − $19,250) / 36 = $404/month. Finance = ($33,795 + $19,250) × 0.00125 = $66/month. Pre-tax payment: $470/month.
A $3,000 cap cost reduction would drop the payment by about $87/month -- but you'd be paying $3,000 upfront for a leased vehicle you don't own. Most financial advisors recommend keeping cap reductions low on leases.
Car Lease FAQs
What is money factor and how does it relate to APR?
Money factor is the leasing equivalent of an interest rate, expressed as a very small decimal (e.g. 0.00125). Multiply it by 2,400 to get the approximate APR. A money factor of 0.00125 is roughly 3% APR. Dealers sometimes quote money factor in "points" (0.00125 = 1.25 points) -- always confirm the actual decimal.
Should I put money down on a lease?
Generally, no. A down payment (cap cost reduction) lowers your monthly payment but you lose that money if the car is totaled -- gap insurance typically covers the loan balance, not your prepaid depreciation. Most leasing experts recommend putting as little down as possible and keeping monthly payments manageable instead.
What happens if I go over my mileage allowance?
You pay a per-mile overage fee at lease end, typically $0.15--$0.30 per mile. If you know you'll exceed the allowance, negotiate a higher mileage lease upfront (cheaper per mile than paying overages) or purchase extra miles at signing.
Can I negotiate a car lease?
Yes -- and you should. The cap cost (negotiated price) is fully negotiable, just like a purchase price. The money factor and residual are set by the lender and typically can't be changed, but dealers can sometimes apply manufacturer subvented rates. Always negotiate the selling price before discussing lease terms.
Lease terminology
MSRP (Manufacturer's Suggested Retail Price)
The sticker price of the vehicle. Used to calculate the residual value (residual % x MSRP). Not necessarily what you pay -- always negotiate the cap cost below MSRP.
Cap Cost (Capitalized Cost)
The negotiated selling price of the vehicle -- the starting point for your lease calculation. Lower is better. Treat it exactly like negotiating a purchase price.
Adjusted Cap Cost
Cap cost plus any fees rolled into the lease (acquisition fee, dealer fees), minus cap cost reduction (down payment, trade-in, rebates). This is the actual figure used to calculate your payment.
Residual Value
The projected value of the vehicle at lease end, expressed as a percentage of MSRP and set by the lender. You only finance the depreciation (adjusted cap cost minus residual). Not negotiable.
Money Factor
The lease equivalent of an interest rate. Multiply by 2,400 to convert to approximate APR. A dealer markup on money factor is pure profit -- ask for the "buy rate" money factor to ensure you're getting the lender's base rate.
Acquisition Fee
A lender fee charged at lease inception, typically $595--$995. Usually rolled into the cap cost rather than paid upfront. Not negotiable with the lender, but the dealer sometimes absorbs it as a sales incentive.
