What does depreciated asset mean?
A fully depreciated asset is a property, plant or piece of equipment (PP&E) which, for accounting purposes, is worth only its salvage value. Whenever an asset is capitalized, its cost is depreciated over several years according to a depreciation schedule.
When should you depreciate an asset?
If you have an asset that will be used in your business for longer than the current year, you are generally not allowed to deduct its full cost in the year you bought it. Instead, you need to depreciate it over time. This rule applies whether you use cash or accrual-based accounting.
What happens when you fully depreciate an asset?
You have fully depreciated these assets in the previous reporting periods. And as a result, the matching principle does not work here. The expenses simply do not match the benefits gained from these machines.
How many entities simply forget the annual depreciation charge?
You would not believe how many entities simply forget it! They just book the annual depreciation charge based on the rates determined for some group of assets and that’s it. They do not revise the useful lives of their assets and as a result, they end up with using fully depreciated assets in the production process.

Why are machines fully depreciated but we still use them?

So in fact, you use the machines, but you can’t really recognize any depreciation expense, because there’s nothing left. You have fully depreciated these assets in the previous reporting periods.
