# Depreciation

The **Depreciation** feature supports multiple depreciation methods and enables automatic calculation of depreciation values based on asset data. It can be used either for quick estimates or as a saved calculation within asset records when the required fields are present.

The available methods include the following:

* Straight Line
* Declining Balance
* Sum of Years
* Units of Production
* Double Declining

There are no prerequisites for using the basic version of depreciation, which allows entering values directly to estimate results. However, to save depreciation values to records and enable automated calculations, the following fields must be added to the collection. Field names must be spelled exactly as listed, although capitalization does not affect functionality.
