MACRS Depreciation Calculator

200% Declining Balance Method (GDS)
150% Declining Balance Method (GDS)
Straight-Line Method (SLM) over GDS

What is MACRS Depreciation?

MACRS is the U.S. tax depreciation system that allows tangible assets to be depreciated over their useful life. It starts with a declining balance method and switches to straight-line when advantageous. Introduced in 1986, it replaced the ACRS system.

MACRS Depreciation Formula:

Di = C × Ri

Where:

Di = depreciation for year i
C = asset cost (basis)
Ri = depreciation rate for year i based on IRS tables

How to Use the MACRS Calculator

Enter the asset basis (purchase price).
Enter property use percentage.
Select the recovery period (e.g., 3, 5, 7, 10, 27.5, 39 years).
Choose depreciation method (200% DB, 150% DB, or SLM).
Select applicable convention (half-year, mid-quarter, etc.).
Enter the date the asset was placed in service.
Click Calculate to generate the depreciation schedule.

MACRS Depreciation Methods

200% Declining Balance (GDS)

Double the straight-line rate. Maximizes early-year deductions, switches to straight-line when more beneficial.

150% Declining Balance (GDS)

1.5× straight-line rate. Higher early-year deductions, switches to straight-line as advantageous.

Straight-Line Method (SLM)

Provides equal annual depreciation except first and last year. Useful for consistent expense reporting.

IRS MACRS Property Class Examples

Computer equipment: 5-year property
Office furniture: 7-year property
Residential rental property: 27.5-year property
Non-residential real property: 39-year property

Choosing a Depreciation Method

Businesses may choose accelerated methods (200% or 150% DB) for early tax benefits or SLM for steady expense reporting. Method selection affects tax savings and reported profits.
