## How to use the DB function

The DB function calculates the depreciation of an asset for a given period using the fixed-declining balance method.

Formula in cell F3:

=DB($C$3,$C$4,$C$5,E3)

### Excel Function Syntax

DB(*cost, salvage, life, period, [month]*)

### Arguments

Cost |
Required. What you pay for the asset. |

Salvage |
Required. The value of the asset at the end of depreciation. |

Life |
Required. The number of periods the asset is being depreciated. |

Period |
Required. The period you want to know the depreciation of. |

[Month] |
Optional. The number of months in the first year. |

### Comments

The DB function calculates the depreciation of a period like this:

(*cost* - total depreciation from prior periods) * rate

where:

rate = 1 - ((*salvage* / *cost*) ^ (1 / *life*))

The first period is calculated like this:

*cost* * rate * [*month]* / 12

The last period is calculated like this:

((*cost* - total depreciation from prior periods) * rate * (12 - [*month*])) / 12
