A lease payment has two parts. The depreciation charge spreads the car's expected loss in value, the net capitalized cost minus the residual value, evenly over the term. The finance (rent) charge is the money factor times the sum of the net capitalized cost and the residual. Sales tax, where it is charged on each payment, is added on top.

With the defaults, a 35,000 car negotiated to 33,000 with 2,000 down, a 58% residual of 20,300, a money factor of 0.0025 and a 36-month term, the payment is 297.22 of depreciation plus 128.25 of finance charge: 425.47 before tax and 451.00 with 6% tax.

Multiplying the money factor by 2,400 gives an approximate APR, 6% here. That conversion is an industry rule of thumb; no federal rule defines it. Acquisition and disposition fees, mileage overage and wear charges are not included unless you add them to the price.

## よくある質問

### How is a car lease payment calculated?

Add the depreciation charge, (net capitalized cost − residual) ÷ months, to the finance charge, (net capitalized cost + residual) × money factor, then add any tax. For a net cost of 31,000, a residual of 20,300 and 36 months, depreciation is 10,700 ÷ 36 = 297.22 and the finance charge is 51,300 × 0.0025 = 128.25, so the payment is 425.47 before tax.

### How do you convert a money factor to an APR?

Multiply the money factor by 2,400: 0.0025 × 2,400 = 6%. To go the other way, divide the APR by 2,400, so 4.8% is a money factor of 0.002. The Federal Reserve notes that no federal standard defines this conversion; it is an industry rule of thumb, and the lease contract's rent charge is the figure that counts.

### How does the residual value affect a lease payment?

A higher residual lowers the payment, because you pay only for the value the car loses during the lease. On the default 35,000 car, a 55% residual (19,250) gives a payment of 479.13 with tax, 58% gives 451.00 and 62% gives 413.49. The residual is usually also the buyout price at the end of the lease, before any purchase-option fee.

### Is it better to negotiate the price or put more money down on a lease?

Negotiate the price first. Cutting the price by 1,000 and putting 1,000 more down both lower the payment by 32.09 a month with 6% tax (30.28 before tax), but only the price cut keeps the 1,000 in your pocket: the total cost of the default lease falls to 17,080.62 against 18,080.62 with the extra down payment.
