# Depreciation Expense: Explained

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

Ah, depreciation. The bane of my existence as a CFO. Those dreaded expenses that just seem to keep coming and coming, eating away at our bottom line. But, as much as I might complain about it, the truth is that depreciation expense is an essential part of any business. And if you want to make sure you're doing it right, you need to understand what it is and how it works.

So, what exactly is depreciation? Simply put, it's the process of gradually writing off the cost of an asset over its useful life. Let's say your company buys a piece of machinery for \$100,000. Instead of writing off the entire cost in the year it was purchased, you spread that cost out over the number of years the machinery is expected to be useful. This way, you get a more accurate picture of the asset's true cost to the business.

Now, there are a few different methods you can use to calculate depreciation. The most common one is straight-line depreciation, where you divide the cost of the asset by its useful life to determine the annual depreciation expense. So, if your \$100,000 machine has a useful life of 10 years, you would write off \$10,000 of its cost every year.

Another method is accelerated depreciation, which allows you to write off more of the asset's cost in the early years of its life and less in the later years. This can be a good option if the asset is expected to have a higher value at the beginning of its life and decrease in value over time.

So, why bother with all of this? Well, for one thing, it's required by accounting standards. But beyond that, calculating depreciation expense is essential for accurate financial reporting. It allows you to match the cost of an asset with the revenue it generates over its useful life, giving you a more accurate picture of your profits and losses.

It's also important to note that depreciation can have an impact on your taxes. While it's not a direct deduction, it does reduce your taxable income, which can lead to lower tax bills.

Now, as much as I love talking about accounting standards and tax deductions, I know that not everyone shares my passion. So, let me try to put this in terms that might be a little more relatable.

Think of it this way: depreciation is like the wear and tear on a car. When you drive a brand new car off the lot, it immediately loses value. And over time, as you drive it more and more, it continues to decrease in value. Just like that car, an asset that your company purchases will also decrease in value over time. By calculating depreciation, you're just acknowledging that fact and accounting for it in your financial statements.

So, there you have it. Depreciation expense might seem like a headache, but it's really just a necessary part of doing business. Whether you're using straight-line or accelerated depreciation, make sure you understand how it works and why it matters. Your bottom line will thank you in the end.
