Before knowing about this macrs depreciation calculator, let’s start with the term ‘Macrs Depreciation.’

What Is MACRS Depreciation?

MACRS is an acronym for the Modified Accelerated Cost Recovery System; it is the tax depreciation system used in the United States. Well, this depreciation schedule will begin with a declining balanced (DB) method, and then it will switch to a straight line (SL) schedule to finish the depreciation schedule. Under MACRS, the amount of the tangible property is depreciated over a useful life of the asset.

The Modified Accelerated Cost Recovery System was introduced in 1986, according to MACRs method; generally the property placed into service after the date will be depreciated. It is a modification of the ACRS (Accelerated Cost Recovery System) that was in use from 1981-1986.

In simple words, MACRS accelerated the cost recovery (depreciation) of an asset but outcomes in the same net depreciation as an individual would receive under straight-line depreciation. Remember that the taxpayer gets feasibility from MACRS depreciation as he/she gets a lower net present value for their tax burden.

Additionally, the method groups several types of assets into different classes that are shown in the given table. Our macrs depreciation calculator also utilizes the same classes while calculating depreciation.

200% Declining Balance Method (GDS):

It is the method in which the depreciation rate is double the straight-line depreciation rate and also provides the highest tax deduction during the first few years, and then changes to the SLD method when that method provides an equal or greater deduction. You just have to plug your values in the macrs calculator and allow it to do the math for you.

150% Declining Balance Method (GDS):

It is another method that provides a greater depreciation rate of 150% more than the straight-line method and then changes to the SLD amount when that method provides an equal or greater deduction.

Straight Line Method (SLM) Over a GDS Recovery Period:

The SLM (GDS) method is one of the best methods of depreciation that allows for a deduction of the same amount of depreciation every year but except the first and last year of service.

Our accurate macrs depreciation calculator also follows these methods while calculating depreciation for given values.

IRS MACRS Depreciation Calculation Schedule:

Classification of Asset Property:

For instance:

  • Computer component is classified as 5-year property
  • Office furniture/asset is classified as 7-year property
  • Residential rental property, it is classified as 27.5-year property
  • Non-residential real property, it is classified as 39-year property

Selection of the Depreciation Method:

Small business owners or certain owners may aim to account a smaller tax deduction in the early years, if they expect business profits to increase in later years or aim to show higher profits in earlier periods. Generally, it is best to choose the higher depreciation rates in the earlier years for maximum tax savings.

The Period when the Asset was Placed And Disposed of Service:

How Does MACRS Work?

If you want to determine how tangible property should be depreciated, the Internal Revenue Service (IRS) has set up different asset classes.

A specialized piece of HVAC can be depreciated over a 7 or 5 years life rather than the normal 27.5 or 39-year life. MACRS helps to depreciating these components of property by allowing a taxpayer to recover their annual deductions over the exact life of the tangible property. If the taxpayer chooses to use the General Depreciation System versus using the Alternative Depreciation System, then the class life will be different.
