# Depreciation: Explained

## What is it, how to calculate it, formula, why it's important

Hey there! As the CFO of a company, I know that depreciation can be a confusing topic. But let me tell you, it's an important one to understand! So, sit back, relax, and let me explain it to you in a way that makes sense.

## What is Depreciation?

Let's start with the basics. Depreciation, in a business context, is the decrease in value of an asset over time due to wear and tear, obsolescence, or other factors.

For example, let's say your company buys a new computer for \$1,000. Over time, that computer will become outdated, slower, and less valuable. This decrease in value is what we call depreciation.

## Why is Depreciation Important?

Depreciation is important because it helps us to accurately measure a company's profits. When a company buys an asset, it's not counted as an expense all at once. Rather, the cost is spread out over the life of the asset through depreciation.

By doing this, we can accurately reflect how much of an asset's value has been used up over time. This, in turn, allows us to calculate a more accurate net income for the company.

## How is Depreciation Calculated?

Great question! There are actually a few different methods for calculating depreciation. Let me break them down for you:

### Straight-line Depreciation

The straight-line method is the most common method for calculating depreciation. It's simple and straightforward, hence the name. With this method, the depreciation expense is the same amount every year for the life of the asset.

Let's go back to our computer example. If we assumed that the computer had a useful life of 5 years and no salvage value (meaning it's worth nothing at the end of its useful life), we could calculate the annual depreciation expense as follows:

Depreciation expense = (Cost of asset - Salvage value) / Useful life

So, in this case:

Depreciation expense = (\$1,000 - \$0) / 5 = \$200 per year

Simple, right?

### Double-Declining Balance Depreciation

The double-declining method is a bit more complex. With this method, the depreciation expense is higher in the early years of an asset's life and decreases over time. This is because the asset is losing value at a faster rate in the early years.

Using our computer example again, let's assume that we're using the double-declining balance method and the computer has a useful life of 5 years:

Year 1: Depreciation expense = Book value x (2 / Useful life) = \$1,000 x (2 / 5) = \$400

Year 2: Depreciation expense = Book value x (2 / Useful life) = (\$1,000 - \$400) x (2 / 5) = \$240

And so on...

### Units of Production Depreciation

The units of production method is used when an asset's value is based on how much it's used, rather than how much time has passed. For example, a manufacturing company might use this method to calculate the depreciation of a machine that produces a certain number of units.

With this method, the depreciation expense is calculated based on how much the asset was used during the year. So, if the company produced 10,000 units during the year and the machine has a total life of 100,000 units, the depreciation expense would be calculated as follows:

Depreciation expense = Cost of asset / Total units of production x Units produced during the year

## Wrapping Up

Well, there you have it - a crash course in depreciation! While it may not be the most exciting topic in the world, it's definitely an important one to understand as a business owner.

Remember, there are a few different methods for calculating depreciation, so be sure to choose the one that works best for your company. And, as always, if you're ever unsure about something, don't hesitate to ask your friendly neighborhood CFO (that's me!).
