## Excel SLN Function

The SLN function calculates the depreciation of an asset for one period based on the straight-line depreciation method.

#### Syntax

=SLN(cost, salvage, life)

#### Arguments

• cost (required): The initial cost of the asset.
• salvage (required): The value of the asset at the end of the depreciation.
• life (required): The number of periods over which the asset is depreciated.

#### Return Value

The SLN function returns a numeric value.

#### Function Notes

• SLN will return the #DIV/0! error if life = 0.
• SLN will return the #VALUE! error if any argument contains a non-numeric character (note that in the example above, cost and salvage are numbers that were formatted as currency with the Format Cells feature).

#### Example

As the below screenshot shown, an asset had an initial cost of \$10,000 and a salvage value of \$1,000. The asset will depreciate over 5 years. To get its straight-line depreciation for each year, please copy or enter the formula below in a blank cell, and press Enter to get the result:

=SLN(10000,1000,5)

Or, use cell references to make the formula dynamic:

=SLN(C3,C4,C5)
