## SYD Function

The SYD function in Google Sheets calculates the sum-of-years’ digits depreciation of an asset over its useful life.

### Syntax

```
SYD(cost, salvage, life, period)
```

`cost`

: The initial cost of the asset.`salvage`

: The salvage value of the asset at the end of its useful life.`life`

: The number of periods (usually years) over which the asset will be depreciated.`period`

: The period for which you want to calculate the depreciation.

### Examples

**Basic Depreciation Calculation**

Calculate the depreciation for the 3rd year of an asset costing $5000 with a salvage value of $500 over 5 years:

```
=SYD(5000, 500, 5, 3)
```

This will output 900.

### Notes

- Depreciation is weighted more heavily in the earlier years of the asset’s life.
- The result represents the depreciation expense for the specified period.
