About Rental Property Depreciation (MACRS 27.5-Yr) Calculator

The Rental Property Depreciation Calculator computes the valuable non-cash tax depreciation write-off on residential real estate over 27.5 years (or 39 years for commercial), excluding land value.

Formula & Mathematical Calculation

Depreciable Building Basis = Total Purchase Price + Purchase Closing Costs - Land Value (Typically 15-20%)

Annual Residential Depreciation = Depreciable Building Basis / 27.5 Years (3.636% per year)

Calculation Example

$400,000 Rental Property ($80,000 Land Value → $320,000 Depreciable Building Basis): Annual Tax Depreciation Deduction = $11,636.36/year ($969.70/month non-cash tax shelter!).

Frequently Asked Questions

Depreciation is a paper deduction that offsets rental income for tax purposes without requiring an actual cash outlay, often allowing landlords to pay zero income tax on positive rental cash flow.

It adds the purchase closing costs to the total purchase price and subtracts the land value, since land is not depreciable. On a $400,000 purchase with $80,000 of land value and no separate closing entry, the depreciable building basis is $320,000.

The calculator divides the depreciable basis by 27.5 years, the residential straight-line recovery period built into the tool. A $320,000 basis produces about $11,636 of annual depreciation, or roughly $970 per month.

The purchase price must be greater than zero, and the resulting basis must also be positive. If the land value entered is not less than the purchase price, the calculator stops with 'Land value must be less than the purchase price.'

Only the building structure loses value over time for tax purposes; land does not depreciate. The calculator therefore removes the land value from the purchase price before dividing the remaining building basis over the recovery period.
