Estimate your Year-1 tax benefit in 60 seconds.
Pick a property type, enter a purchase price, set your bracket. We use the same RSMeans 2024 cost data and IRC §168(k) framework as the engineered study itself — so the estimate reflects what an actual report would conclude, not a sales pitch.
How the estimate is built.
We start with the building's depreciable basis (purchase price minus an assumed land allocation — 20% residential, 15% commercial), then apply a property-type-specific reclassification percentage based on aggregate component data from completed studies. That reclassified portion is fully deductible in Year 1 under 100% bonus depreciation (OBBBA, signed July 2025). Multiplying by your federal bracket gives the estimated cash benefit.
Real reports vary with property age, condition, geography (RSMeans regional cost multipliers), and finish-level — an actual study can be 10–20% above or below the calculator's estimate. The calculator is intended as a decision tool ("is this big enough to be worth ordering?"), not a substitute for the engineered analysis.
