     [ http://tools.oasis-open.org/issues/browse/OFFICE-2221?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Eike Rathke updated OFFICE-2221:
--------------------------------

    Proposal: 
Change "sum-of-years' digits method" to "Sum-of-the-Years'-Digits method" that apparently is the correct name.

Add formula as given at  http://wiki.services.openoffice.org/w/index.php?title=Documentation/How_Tos/Calc:_SYD_function

To calculate depreciation, SYD adds the year numbers during the asset's life; the year numbers taken backward and divided by that sum give the proportion of the total loss of value to assign to depreciation that year.

SYD = (originalcost - salvagevalue) * (lifetime+1 - year) * 2 / ((lifetime+1) * lifetime)
