## How to Calculate Rental Property Depreciation

When owning or managing a rental property, it is important to know how to calculate rental property depreciation. Depreciation is an accounting strategy that makes it possible to distribute expenses (such as the cost of acquiring a rental property) over time.

While calculating rental property depreciation is fairly straightforward, there are a few unique nuances that rental property owners should keep in mind.

Most notably, as a result of regulations established by the IRS, rental property owners need to use a modified prorated formula that moves the depreciation entry to the middle of the month, rather than the beginning or end of the month.

Don’t worry. It’s not as complicated as it sounds. In this brief guide, we will help answer the questions you might have about calculating rental property depreciation.

### What is Depreciation?

One thing that many people tend to overlook is that depreciation is a cost allocation strategy, rather than an accurate estimate of how an asset’s value has changed over time.

By calculating depreciation, the expense of an asset (including rental property) can be distributed over the course of that asset’s useful life, rather than being accrued all at once.

For rental property owners, depreciation calculations can be used not only for the property itself but also for any investment they’ve made that has a limited useful life.

### Straight-Line Depreciation

There are many different depreciation calculation strategies you might consider, but the most common is straight-line depreciation. This straightforward formula will evenly distribute the costs of acquiring an asset (cost basis) over its useful life.

The straight-line depreciation method results in a linear distribution of costs (instead of an exponential distribution), which makes it very easy to calculate, and all you need to know are the cost basis of the asset and the recovery period (useful life).

#### Straight-Line Depreciation Formula

The straight line depreciation formula for a full year is:

depreciation = cost basis / recovery period

So, if the cost basis were \$500,000 and the recovery period was 10 years, the yearly depreciation value would be \$50,000.

### Depreciation for Rental Properties

As mentioned earlier, rental property owners will need to make a slight adjustment to their depreciation calculation because the IRS requires depreciation to be allocated in the middle of the month instead of at the end of the year.

### Prorated First Month Depreciation Formula

The IRS requires that the depreciation for the first year be prorated for the number of months the property is in use. The straight line depreciation formula for a partial first year prorated for the number of months in use is:

1st year depreciation = (12 – month) + 0.5 / 12 × cost basis / recovery period

As you can see, the only part of this formula that is different from the standard straight-line depreciation method is the first part, which accounts for the monthly adjustment.

So, if you are the owner of a rental property, be sure you update your books at least once per month.
