# Depreciation Types

There are currently **three** Depreciation models you have access to in the `Settings > Depreciations` section of the left-side navigation.

## Linear

Also called *straight-line depreciation* , linear depreciation is a method that spreads an asset’s depreciable cost over its active use, which is calculated like this:

`$current_value = $cost - ($cost - $floor) * ($months_passed / $months_total);`

## Half Year Convention, applied with condition

This type of depreciation assumes an asset has been in active use for half of its first year *despite* when it was *actually* acquired. When Half Year Convention is applied with condition, the other half of depreciation is only recognized after the midpoint of the last fiscal year of the asset.

## Half Year Convention, always applied

Same as applied with condition, but the final half of depreciation is considered taken as soon as you enter the last fiscal year (no mid-year gating).
