The short answer: if your property is worth $200K+ and you're in the 24% bracket or above, cost segregation almost certainly pays for itself — but here's the detailed math.
| MACRS Class | Amount | % of Accelerated | Bonus Eligible |
|---|---|---|---|
| 5-Year Property | $43,200 | 60% | Yes — 100% |
| 7-Year Property | $7,200 | 10% | Yes — 100% |
| 15-Year Property | $21,600 | 30% | Yes — 100% |
| 27.5yr Property | $328,000 | 82% | No — standard schedule |
| Total Depreciable Basis | $400,000 | 100% | — |
| Method | Year-1 Deduction | Difference |
|---|---|---|
| Standard Straight-Line (27.5yr) | $14,545 | — |
| With Cost Segregation + Bonus | $72,000 | +$57,455 |
Cost segregation makes economic sense when the tax savings from accelerated depreciation significantly exceed the cost of the study. For most investors, this threshold is lower than expected. A $300K rental property generates roughly $16K in first-year tax savings against a study cost of $795 — a 20x return. Even at $200K, the math works: $10K in savings versus $795 in cost.
The cases where cost segregation may NOT be worth it: properties under $150K where the absolute dollar benefit is small; investors in the 12% or lower tax bracket where the savings don't justify the effort; properties you plan to sell within 1-2 years (depreciation recapture offsets much of the benefit); or properties with unusually high land values (beachfront lots, urban land banking) where the depreciable basis is small relative to purchase price.
The strongest ROI comes from three scenarios: (1) Airbnb/STR investors who materially participate and can deduct against W-2 income, (2) investors in the 32-37% tax bracket where every reclassified dollar generates maximum savings, and (3) commercial property owners whose 39-year default schedule makes acceleration most impactful. If you fit any of these profiles, cost segregation is one of the highest-ROI investments you can make.
One common misconception: cost segregation doesn't create new deductions — it accelerates existing ones. You'll eventually depreciate the full building value regardless. The benefit is the time value of money: $50K in tax savings today is worth far more than $50K spread over 27.5 years. At a 7% discount rate, the present value advantage of accelerated depreciation is roughly 60-70% of the total amount reclassified.

| $300K | $43,200 | $15,984 | $795 | 20x |

| Property Type | Accelerated | Tax Savings | Study Cost | ROI |

A cost segregation study is an engineering-based analysis that reclassifies components of your property into shorter IRS depreciation categories (5, 7, and 15 years) instead of the default 27.5 or 39 years. This accelerates your depreciation deductions, reducing your tax bill in the early years of ownership.
Generally, cost segregation delivers positive ROI on properties valued at $200K and above for investors in the 24%+ tax bracket. The study cost starts at $795 for residential properties, and even a $200K rental generates roughly $10K in first-year tax savings — a 12x return on the study cost.
When you sell a property, the IRS recaptures accelerated depreciation at a maximum rate of 25%. However, the time value of money strongly favors taking the deduction now: $50K in tax savings today is worth far more than paying $12,500 in recapture tax years later. Additionally, a 1031 exchange can defer recapture indefinitely.

Yes. The economics of cost segregation are determined by the property value and your tax bracket, not the number of properties you own. A single $400K rental property typically generates $21K in first-year tax savings — more than enough to justify the $795 study cost. The deductions carry forward if they exceed your current-year passive income.
