When you invest in real estate, understanding property depreciation is key to maximizing your tax benefits and financial returns. Depreciation allows investors to deduct the gradual wear and tear of their property over time — effectively reducing taxable income.
Our Investment Property Depreciation Calculator is a free online tool that simplifies this process. By entering your property cost, land value, and depreciation period, you can instantly find out your depreciable amount, annual depreciation, and total depreciation — without any manual math.
Whether you’re a seasoned investor or just starting in real estate, this tool provides accurate results to help you plan better and save more.

What Is Property Depreciation?
Property depreciation refers to the decline in the value of a building or asset over time due to factors such as aging, wear and tear, and obsolescence. While land itself doesn’t depreciate, the building structure and other improvements do.
For investment properties, this depreciation can be claimed as a tax deduction, allowing you to offset part of your rental income — and ultimately pay less tax.
Depreciation is a non-cash deduction, meaning you don’t spend any money to claim it. Instead, it’s a paper-based expense that reflects the decreasing value of your property’s assets over time.

How to Use the Investment Property Depreciation Calculator
Using this calculator is incredibly easy. Follow these steps:
- Enter Property Cost:
Input the total cost of your property, including the building but excluding land if known. - Enter Land Value:
Add the estimated value of the land portion. (Land doesn’t depreciate, so this is excluded from the depreciable amount.) - Depreciation Period (Years):
Enter the number of years you wish to calculate depreciation for — typically between 20 to 40 years depending on your property and tax laws. - Click “Calculate”:
Once all fields are filled, hit the Calculate button. The tool will automatically display:- Depreciable Amount
- Annual Depreciation
- Total Depreciation
- Reset Anytime:
Use the Reset button to clear inputs and start a new calculation instantly.
Example Calculation
Let’s see how it works with a simple example:
- Property Cost: $400,000
- Land Value: $100,000
- Depreciation Period: 40 years
Step 1: Depreciable amount = Property cost – Land value
→ $400,000 – $100,000 = $300,000
Step 2: Annual depreciation = Depreciable amount ÷ Years
→ $300,000 ÷ 40 = $7,500 per year
Step 3: Total depreciation over 40 years = $7,500 × 40 = $300,000
So, over 40 years, you could potentially claim $7,500 per year in depreciation deductions — saving thousands on taxes annually.
