Rental Property Depreciation Calculator
Estimate building depreciation with a simple basis approach
A Rental Property Depreciation Calculator can help real estate investors get a quick estimate of how much building value may be deducted each year. For US rental property, the key step is separating land from the purchase price, because land is not depreciable. Once you estimate the building basis, you can apply the standard straight-line recovery period for either residential or commercial rental property.
What this calculator helps you do
This tool is built for straightforward planning. You enter the purchase price, subtract land value or use a land percentage, then add basis-related costs such as certain closing costs and capital improvements. From there, the calculator estimates annual depreciation using 27.5 years for residential rentals or 39 years for commercial rentals.
If you enter a placed-in-service date and tax year, the tool can also show a simplified first-year estimate. That gives investors a practical starting point when reviewing cash flow, projected deductions, or acquisition assumptions.
Important tax note
A rental property depreciation calculator is useful for planning, but it is still only an estimate. MACRS conventions, special asset classifications, and other tax details can affect actual results. For filing decisions, confirm the treatment with a qualified CPA or tax professional.
FAQs
How do I figure out the building basis for depreciation?
Start with the purchase price, then remove the value of the land because land cannot be depreciated. After that, add closing costs that are properly allocable to basis and any capital improvements that should be capitalized. The result is the estimated building basis used for the depreciation calculation. If your land value is not known in dollars, a reasonable land percentage can be used as a simple estimate.
What recovery period does the calculator use?
For residential rental property, the calculator uses 27.5 years. For commercial rental property, it uses 39 years. Those are the standard straight-line recovery periods commonly associated with these property types. This tool is designed for quick estimating, so it does not attempt to handle every exception, adjustment, or special classification that may apply in real tax filings.
Is the first-year depreciation result exact?
No. If you enter a placed-in-service date and tax year, the tool can provide a simplified first-year estimate to help with planning. Actual tax depreciation may differ because IRS MACRS conventions, mid-month rules, partial-year treatment, prior allocations, improvements placed in service separately, and other facts can change the result. It is smart to use this as an estimate and confirm the final treatment with a CPA or tax professional.
