Rental Property Depreciation Calculator
This calculator determines the annual depreciation deduction for US residential rental property under IRS MACRS GDS rules (Publication 527). Depreciation is one of the most valuable tax deductions available to rental property owners — it lets you deduct the cost of the building structure over 27.5 years, reducing your taxable rental income even when the property may be appreciating in value. Enter your purchase price, land value, and any capitalized closing costs or improvements to see your annual and monthly deduction.

How to use this calculator
- 1
Enter the purchase price
The total price paid for the property including the building and land. If you inherited or received the property, use the fair market value at the time you placed it in service as a rental.
- 2
Enter the land value
Land is never depreciable under IRS rules. Enter the assessed or appraised value of the land component only. A common approach is to use the county assessor's land-to-improvement ratio applied to your purchase price. If the land value is unknown, a rough estimate of 20–30% of purchase price is sometimes used — consult a CPA or appraiser for the correct figure.
- 3
Enter capitalized closing costs (optional)
Certain closing costs that are directly attributable to acquiring the property — such as title insurance, recording fees, and legal fees — can be added to your depreciable basis. Loan origination fees and prepaid property taxes are typically not capitalized. Leave at $0 if you are unsure.
- 4
Enter capital improvements (optional)
Major improvements that extend the useful life of the property (new roof, HVAC system, additions) are added to the depreciable basis. Routine repairs and maintenance are not capitalized and are expensed directly.
- 5
Enter your marginal tax rate
Your estimated federal marginal income tax rate as a percentage (e.g., 22, 24, 32). This is used to estimate the annual tax savings from the depreciation deduction. Check the current IRS tax brackets for your filing status.
- 6
Read your depreciation deduction
The calculator shows your annual and monthly depreciation deduction, your depreciable basis, estimated annual tax savings, and the total depreciation schedule length (27.5 years).
Formula
Depreciable Basis = Purchase Price − Land Value + Capitalized Closing Costs + Improvements
Annual Depreciation = Depreciable Basis ÷ 27.5
Monthly Depreciation = Annual Depreciation ÷ 12
Estimated Annual Tax Savings = Annual Depreciation × (Marginal Tax Rate ÷ 100)Under IRS MACRS GDS (General Depreciation System), residential rental property is depreciated using the straight-line method over 27.5 years. The depreciable basis starts with the purchase price, subtracts the non-depreciable land value, and adds any capitalized closing costs and improvements. Dividing by 27.5 gives the annual deduction. Source: IRS Publication 527 — Residential Rental Property. Example: Purchase price $320,000, land value $60,000, closing costs capitalized $4,000 — depreciable basis = $264,000, annual depreciation = $264,000 ÷ 27.5 = $9,600, monthly = $800. At a 24% tax rate, estimated annual tax savings = $9,600 × 0.24 = $2,304.
Worked Example
Purchase Price: $320,000 Land Value: $60,000 Capitalized Closing Costs: $4,000 Capital Improvements: $0 Marginal Tax Rate: 24% Depreciable Basis = $320,000 − $60,000 + $4,000 = $264,000 Annual Depreciation = $264,000 ÷ 27.5 = $9,600.00/yr Monthly Depreciation = $9,600 ÷ 12 = $800.00/mo Estimated Annual Tax Savings = $9,600 × 0.24 = $2,304.00 The property depreciates over 27.5 years from the date it was first placed in service as a rental. If you sell before then, any depreciation claimed is subject to recapture (taxed up to 25%) under IRS Section 1250.
