If you own commercial or residential rental property and your tax advisor has mentioned a cost segregation study, the first question is usually: "How much does it cost?" The second — and more important — question is whether the return justifies the investment. The short answer: for most property owners, a cost seg study pays for itself 6 to 12 times over in accelerated tax savings.
Here's what you need to know about pricing, what drives costs up or down, and how to evaluate the ROI before you write the check.
Typical Cost Segregation Study Pricing
Cost segregation study fees vary based on the property, but here are the ranges we see most often:
Some firms offer flat-fee pricing, while others charge based on a percentage of the reclassified assets or the total property value. Be wary of firms that charge a percentage of "tax savings identified" — that model can create incentives to inflate projections.
What Drives the Cost of a Study?
Five primary factors determine where your study falls within the pricing range:
1. Property value. A $750K rental duplex is a simpler engagement than a $5M mixed-use building. Higher-value properties have more components to analyze and reclassify, which takes more engineering time.
2. Property type. Restaurants, medical offices, and manufacturing facilities tend to cost more to study because they have specialized build-outs — kitchen hoods, medical gas systems, heavy-duty electrical — that require detailed component-level analysis. A standard office or apartment building is comparatively straightforward.
3. Building complexity and age. Newer construction with detailed blueprints available costs less to study. Older buildings without original plans may require more site inspection time to document and classify components.
4. Number of properties. Studying multiple properties with the same firm typically reduces the per-property cost. If you own a portfolio of 10 rental properties, the marginal cost of each additional study drops significantly.
5. Lookback studies. If the property was placed in service in a prior year, a lookback study allows you to claim missed depreciation without amending prior returns (via a Section 481(a) adjustment). Lookback studies may cost slightly more due to additional calculations, but they capture all the missed accelerated depreciation in a single tax year.
Cost Segregation ROI: The Numbers That Matter
The real question isn't what the study costs — it's what it returns. A properly executed cost segregation study reclassifies 20–40% of a building's cost basis from 27.5 or 39-year property to 5, 7, and 15-year categories. When combined with bonus depreciation, those reclassified components can be deducted immediately.
| Property Value | Typical Study Cost | Reclassified Assets (est.) | Estimated Tax Savings* | ROI on Study |
|---|---|---|---|---|
| $500,000 | $5,000–$8,000 | $100K–$200K | $30K–$60K | 4–12x |
| $1,000,000 | $7,000–$12,000 | $200K–$400K | $60K–$120K | 5–17x |
| $2,000,000 | $10,000–$18,000 | $400K–$800K | $120K–$240K | 7–24x |
| $5,000,000 | $15,000–$25,000 | $1M–$2M | $300K–$600K | 12–40x |
*Tax savings estimated at a 30% combined federal/state rate. Actual savings depend on marginal tax bracket and state taxes.
The math is simple. If a $10,000 study generates $100,000+ in first-year deductions, you're getting a 10:1 or better return on the study fee. Very few investments in your business deliver that kind of immediate tax benefit.
When a Cost Segregation Study Is Worth It
Not every property justifies a full study. Here's the general threshold:
Strong candidates: Properties valued at $500,000 or more, recently purchased or constructed, with significant build-out or specialized components. Real estate investors with multiple properties benefit enormously from portfolio-wide studies.
Marginal candidates: Properties between $250K–$500K may still benefit, but the savings-to-cost ratio is tighter. Some firms offer "desktop" or abbreviated studies at lower price points ($2,000–$5,000) for smaller properties.
Likely not worth it: Properties under $250K in value, or properties that are mostly land value with minimal building improvements.
What to Look for in a Cost Seg Provider
The quality of the study matters as much as the price. An IRS audit of a poorly documented study can wipe out your savings and then some. Look for:
Engineering-based studies. The IRS has stated that engineering-based studies are the "preferred method." Avoid firms that rely solely on estimates or cost-based approaches without physical inspection or blueprint analysis.
Audit defense included. Reputable firms stand behind their work. If the IRS questions the study, your provider should participate in the defense at no additional charge.
Transparent pricing. Flat fees or clearly defined fee structures beat percentage-of-savings models. You want your provider incentivized to produce accurate results, not inflated projections.
Industry experience. A firm that has completed hundreds of studies across your property type will be faster, more accurate, and better at maximizing legitimate reclassifications.

The cost segregation industry has grown rapidly, and not all providers deliver equal quality. Be cautious of:
Unusually low fees. A $1,500 "study" on a $2M property is almost certainly a template-based estimate, not an engineering analysis. It may not hold up under audit.
Percentage-of-savings pricing with no cap. If the fee is 10–15% of identified savings, a $2M property study could cost $30K–$60K — far more than a flat-fee arrangement.
No site visit offered. While desktop studies have a place for smaller properties, any study on a property over $1M should include physical inspection or detailed blueprint review.
Guaranteed savings amounts before reviewing your property. No legitimate provider can guarantee specific dollar amounts without analyzing the actual building, construction costs, and your tax situation.
Bottom Line: The Study Almost Always Pays for Itself
For property owners with buildings valued at $500K or more, a cost segregation study is one of the highest-ROI tax investments available. The study fee is a fraction of the accelerated deductions it unlocks — and with 100% bonus depreciation restored in 2026, the first-year impact is at its peak.
The cost of the study isn't the risk. The risk is not doing one and leaving six figures in tax savings on the table for the next 27 to 39 years.
