The three numbers behind every lease payment

Capitalized cost, residual value and money factor decide what you pay each month. Here is how they work and which ones you can negotiate.

A monthly lease payment can look like a number pulled from thin air. It is not. Every payment comes from three inputs, and once you understand them you can tell a strong deal from a weak one in seconds.

1. Capitalized cost

The capitalized cost, or cap cost, is the price of the car inside the lease. It works like the sale price when you buy, and it is negotiable. Every dollar taken off the cap cost lowers your payment. Rebates, lease incentives and the value of a trade-in can all reduce it further.

2. Residual value

The residual is what the leasing company expects the car to be worth at the end of the term, expressed as a percentage of MSRP. It is set by the lender, not the dealer, so it is not negotiable. A higher residual is good for you, because you only pay for the gap between the cap cost and the residual.

3. Money factor

The money factor is the lease’s interest rate written as a small decimal, such as 0.00250. Multiply it by 2,400 to get the approximate APR, so 0.00250 works out to about 6.0%. Lenders set a base rate for each credit tier, and dealers are often allowed to mark it up. Knowing the base rate is one of the simplest ways to make sure you are not overpaying.

Putting it together

Here is an illustrative 36-month lease on a car with a $60,000 MSRP:

Negotiated cap cost $55,000
Residual (58% of MSRP) $34,800
Money factor 0.00250 (about 6.0% APR)
Monthly depreciation: ($55,000 − $34,800) ÷ 36 $561.11
Monthly finance charge: ($55,000 + $34,800) × 0.00250 $224.50
Base monthly payment, before tax $785.61

Take another $2,000 off the cap cost and the payment falls by roughly $61 a month. That is why negotiating the price matters just as much on a lease as on a purchase.

The fees to watch

Most leases include an acquisition fee charged by the lender, a dealer documentation fee and registration costs. These are normal, but they should be itemized. Be cautious of any quote that leads with a low monthly payment but asks for a large amount due at signing. Money paid up front simply prepays the lease, so always compare deals on their total cost.

What this means for you

When you get a quote, ask for the cap cost, residual and money factor in writing. If someone will only talk about the monthly payment, that is usually a sign the deal has room in it. At Revlane, we show every number before you sign.
