What Is Depreciation? And Why It's Important
Updated: May 24, 2021
Depreciation is what happens when business assets lose value over time.
It’s an often-forgotten cost of doing business – but it shouldn’t be. Here’s why depreciation is so important:
It costs you money - Depreciation accounting involves working out how much value your assets lose each year, so it can be listed as a loss and subtracted from your revenue.
It can reduce your tax bill - Because depreciation is a business cost, it can lower your tax bill – so it’s important to know how much value you’re losing each year.
It affects the value of your business - If major business assets lose value, the overall value of your business is reduced. Inaccurate tracking could lead to overestimating your business value, which makes it harder to secure finance.
The ins and outs of depreciation
Usually, only long-term or fixed assets can be depreciated, while consumable products aren’t included.
You also need to estimate the item’s lifespan and choose a method to calculate how its value declines over time.
Common methods include:
Straight line depreciation: the asset depreciates by the same amount each year, eventually reaching zero value.
Diminishing value depreciation: the value declines by a higher percentage in the first few years, then the rate of depreciation slows.
Units of production depreciation: the lifespan is calculated by the value delivered, not the time spent using the asset. For example, a business vehicle’s depreciation might be measured in kilometres travelled rather than age.
Accounting for depreciation in your business
