MACRS Accumulated Depreciation Formula:
| From: | To: |
The Modified Accelerated Cost Recovery System (MACRS) is the current tax depreciation system in the United States. Accumulated depreciation represents the total depreciation expense taken on an asset up to a specific point in time.
The calculator uses the MACRS accumulated depreciation formula:
Where:
Explanation: The equation calculates the total depreciation accumulated on an asset by multiplying its original cost by the cumulative MACRS percentage for the given period.
Details: Proper calculation of MACRS depreciation is essential for accurate tax reporting, financial statement preparation, and asset management. It affects taxable income and helps businesses recover the cost of capital investments.
Tips: Enter the original cost of the asset in USD and the cumulative MACRS percentage (as a decimal between 0 and 1). Both values must be valid (cost > 0, percentage between 0-1).
Q1: What's the difference between MACRS and straight-line depreciation?
A: MACRS is an accelerated depreciation method that allows larger deductions in early years, while straight-line spreads deductions evenly over the asset's life.
Q2: How do I find the MACRS percentage for my asset?
A: MACRS percentages are published by the IRS and depend on the asset's recovery period (3, 5, 7, 10, 15, 20, 27.5, or 39 years) and the convention (half-year, mid-quarter, or mid-month).
Q3: Can MACRS be used for all business assets?
A: Most tangible business assets qualify, but land, inventory, and intangible assets don't qualify for MACRS depreciation.
Q4: What happens when an asset is fully depreciated?
A: Once an asset's accumulated depreciation equals its cost, no further depreciation can be claimed, though the asset may still be in use.
Q5: Can MACRS be used for tax purposes outside the US?
A: No, MACRS is specific to US tax law. Other countries have their own depreciation systems.
