Estimate Your Savings

Our Cost Segregation Calculator helps commercial property owners understand the potential tax benefits of accelerated depreciation. By reclassifying building components from 27.5 or 39-year property to 5, 7, or 15-year property, you can significantly increase cash flow through larger immediate tax deductions.


Simply enter your property information below to receive an estimate of potential tax savings. This calculation provides a general overview - for a detailed analysis of your specific property, our engineering-based study would identify all qualifying components.

Please note that actual results may vary based on your property's unique characteristics, acquisition date, and tax situation. The calculator assumes current tax laws and does not constitute tax advice.
