About This Calculator
The Rental Property Depreciation Calculator shows your annual depreciation deduction — one of the most powerful tax advantages of real estate investing. Depreciation allows you to deduct a portion of the property's value each year, reducing your taxable income even while the property may be appreciating in value.
The IRS allows residential rental property to be depreciated over 27.5 years using the straight-line method. Commercial property depreciates over 39 years. Only the building (not the land) is depreciable.
Example: A $350,000 property with $70,000 land value has a $280,000 depreciable basis. Annual depreciation = $280,000 ÷ 27.5 = $10,182/year. At a 28% tax rate, this saves $2,851/year in taxes — nearly $250/month — without any cash outlay.
