How Do You Find Residual Values in a Black Book?

The "black book" is another name for the Residual Percentage Guide, a reference database of car values that is maintained by the Automotive Lease Guide. The black book is a subscription service that costs $100, as of 2016, but Cars.com has an online calculator that approximates residual value.

You may also be able to look up black values for free at your local library, or from a paid leasing assistance service such as FightingChance.com. The residual value of a car is an estimate of how much a leased car may be worth at the end of an auto lease, and it is an important factor in determining monthly lease payments.
