calculus or operation. It describes the future value of a good in terms of absolute value in monetary terms and it is sometimes abbreviated into a percentage of the initial price when the item was new.
Example: A car is sold at a list price of $20,000 today. After a usage of 36 months and 50,000 miles its value is contractually defined as $10,000 or 50%. The credited amount, on which the interest is applied, thus is $20,000 present value minus the present value of $10,000 future value.

Residual values are calculated using a number of factors, generally a vehicles market value for the term and mileage required is the start point for the calculation, followed by seasonality, monthly adjustment, lifecycle and disposal performance. The leasing company setting the residual values (RVs) will use their own historical information to insert the adjustment factors within the calculation to set the end value being the residual value.
In accounting, the residual value could be defined as an estimated amount that an entity can obtain when disposing of an asset after its useful life has ended. When doing this the estimated costs of disposing of the asset should be deducted.
The formula to calculate the residual value can be seen with the next example as follows:
A company owns a machine which was bought for €20,000. This machine has a useful life of five years which has just ended. The company knows that if it sells the machine now it will be able to recover 10% of the price of acquisition.
Therefore, the residual value would be:
$\backslash text\; =\; 10\backslash \%\; \backslash times\; (20000)\; =\; 2000$
