Cost Segregation Calculator

Get a rough estimate of your potential depreciation and tax savings with our cost segregation calculator.

This calculator provides a rough estimate for prospecting purposes. Actual cost segregation studies require detailed engineering analysis.

How This Calculator Works

  1. Depreciable Basis: We subtract the land value from your total property cost, since land cannot be depreciated.
  2. Personal Property: You enter the percentage of your depreciable basis that would be reclassified as 5-year and 15-year property (typically 20-30% for residential properties).
  3. Bonus Depreciation: We apply the appropriate bonus depreciation rate based on when your property was placed in service.
  4. Regular Depreciation: We calculate depreciation on the remaining basis over 27.5 years (residential) or 39 years (Airbnb/short-stay).
  5. Pre-2025 Properties: For properties placed in service before 2025, we subtract the straight-line depreciation already taken from the total so we don't double-count depreciation.

Important Note:

This is a simplified estimate for educational and prospecting purposes. Actual cost segregation studies require detailed engineering analysis and can vary significantly based on your specific property's components, construction methods, and local market conditions. Professional studies typically identify 20–30% of the depreciable basis for reclassification.
