**In Excel, there is a built-in function called “SLN” that can be used to calculate the depreciation of an asset over a period of time using the straight-line method. This blog post will guide you through the process of using the SLN function in Excel to calculate the depreciation value of an asset.**

## Step-by-Step Instructions

The SLN function in Excel requires three arguments:

**Cost**: The initial cost of the asset.**Residual value**: The value of the asset at the end of its useful life.**Life**: The number of periods over which the asset is depreciated.

Create a new excel sheet and input the asset’s cost, residual value, and the asset’s useful life in their respective cells. Then follow the below steps:

- In the cell where you want to perform the SLN function, input the formula “
**=SLN(cost, residual value, life)**”. For example, in our case, the formula will be**=SLN($B$2, $B$3, $B4$4)**. Note that the $ is added to make the cell an absolute reference. - Press
**Enter**to obtain the result. **Drag**the formula down the column to calculate the depreciation value for each year.

## Conclusion

By following these simple steps, you can easily calculate an asset’s depreciation over time using the SLN function in Excel.
