# ATO\_DV 

Calculates depreciation for an asset using the Australian Tax Office (ATO) Diminishing Value method.

```js
ATO_DV(base_value, effective_life, days_held, days_in_year, factor)
```

#### Parameters

* `base_value` - The adjustable (base) value of the asset at the start of the year.
* `effective_life` - The effective life of the asset in years.
* `days_held` - The number of days the asset was held during the income year.
* `days_in_year` - The number of days in the income year, typically 365 or 366.
* `factor` - The rate multiplier for depreciation. Use 2.0 for assets acquired on or after 10 May 2006, or 1.5 for assets acquired between 1 July 2001 and 9 May 2006. Defaults to 2.0 if omitted. `(optional)`

#### Examples

```js
ATO_DV(80000, 5, 365, 365)

```

**Result:** `32000.0`

**Note:** Calculates the first year's depreciation using the Diminishing Value method: $80,000 × (365 / 365) × (200% / 5) = $32,000.

```js
ATO_DV(48000, 5, 365, 365)

```

**Result:** `19200.0`

**Note:** Calculates the second year's depreciation after the base value reduces to $48,000 using the Diminishing Value method.
