Rental Depreciation Calculator

One of the biggest tax advantages of owning rental property is the ability to depreciate the building’s value. Depreciation allows landlords and investors to recover the cost of a property over time by deducting a portion of its value each year.

The Rental Depreciation Calculator makes this process simple. Instead of manually applying IRS formulas, you can quickly determine your annual deduction, accumulated depreciation, and remaining basis for your property.

Whether you own a single rental home or manage multiple properties, this tool helps you maximize tax savings, improve cash flow, and plan smarter investments.

How to Use the Rental Depreciation Calculator

1. Enter Purchase Price
   • Total cost of the property when you bought it.
2. Enter Land Value
   • Land does not depreciate. Only the building value is depreciable.
3. Enter Purchase Year
   • The year the rental property was placed in service.
4. Select Useful Life (IRS Rule)
   • Residential rental property: 27.5 years
   • Commercial property: 39 years
5. Enter Current Year
   • To see how much depreciation has accumulated.
6. Click Calculate
   • Instantly view:
     • Annual depreciation deduction
     • Total accumulated depreciation
     • Remaining book value

Example Calculation

Let’s say you purchased a rental home for $300,000.

• Land Value: $50,000
• Depreciable Value (Building): $250,000
• Useful Life: 27.5 years

Step 1 – Annual Depreciation

$250,000 ÷ 27.5 = $9,090.91 per year

Step 2 – 10 Years of Ownership

10 × $9,090.91 = $90,909 accumulated depreciation

Step 3 – Remaining Basis

$250,000 – $90,909 = $159,091

👉 This means you can deduct $9,090 each year until you’ve fully depreciated the building.
