How much does a cost segregation study cost?

Cost segregation studies range from $499 to $15,000+ depending on the provider type and property complexity. AI-powered platforms with engineering partners charge $499-$4,500 (flat fee). Traditional engineering firms charge $5,000-$15,000+. Free online calculators provide estimates only, not filing-ready studies.

Is a $499 cost segregation study legitimate?

Yes, when backed by actual engineering methodology and a named professional's review. Technology-enabled providers use data-driven analysis (satellite imagery, property records, construction databases, owner-submitted photos) combined with licensed engineer review to deliver studies at lower cost. The key question is whether the study follows the IRS ATG's 13 principal elements — not the price tag.

What is the minimum property value for cost segregation to be worth it?

With study costs starting at $499, cost segregation can be worthwhile for properties with depreciable basis as low as $200,000 (roughly $250,000 purchase price). At a 24% accelerated allocation and 37% tax rate, a $200,000 basis generates approximately $17,760 in first-year savings — a 35x return on a $499 study.

Cost Segregation Under $5,000: Why Studies Don't Have to Break the Bank

For decades, cost segregation was reserved for institutional investors and large commercial property owners. Traditional engineering firms charge $5,000-$15,000+ per study. If your rental property is worth $400,000, an $8,000 study fee eats nearly half the potential tax savings. That pricing barrier locked out the majority of real estate investors — the landlords with one to ten properties, the W-2 earners who bought their first duplex, the short-term rental operators running an Airbnb. Technology has fundamentally changed these economics. Engineering-based studies now start at $499 while maintaining the same IRS-defensible methodology. This guide covers every affordable option, what you get at each price point, and how to determine if cost segregation is worth it for your specific situation.

Cost Segregation Options by Price Tier

Free: Online Calculators

Our free cost segregation calculator provides instant estimates based on real data from thousands of completed studies. Use this to screen whether cost segregation is worth pursuing before spending any money. If the calculator shows less than 5x ROI, cost segregation may not be justified for your property. This is an estimate for decision-making only — not a study you can claim on your tax return.

$99-$500: DIY Software

Reports generated by entering property details into software that applies generic allocation percentages. No engineer reviews the output. No property-specific analysis. Do not file your taxes based solely on a DIY software report. The IRS expects engineering methodology and professional oversight. If audited, a report with no named engineer and generic allocations is unlikely to survive examination. Negligence penalties under IRC Section 6662 can add 20% to any underpayment.

$499-$2,000: Technology-Enabled Engineering Studies

This is the sweet spot for most rental property owners. These studies combine modern data tools — property records, satellite imagery, construction databases, and owner-provided photos — with licensed engineer analysis. The engineer reviews every classification and signs the report. You receive a complete depreciation schedule your CPA can use directly, plus audit defense coverage.

Property Value	Study Cost	Est. Year-1 Savings (35%)	Net Savings	ROI
$350K	~$499	~$23,500	~$23,000	46x
$500K	~$800	~$33,600	~$32,800	41x
$750K	~$1,200	~$50,400	~$49,200	41x
$1M	~$1,500	~$67,200	~$65,700	44x

$5,000-$15,000+: Traditional Engineering Firms

A physical on-site inspection by an engineer who photographs every component, reviews construction blueprints, and prepares a detailed asset-by-asset classification. This is the original cost segregation methodology and remains the gold standard for highly complex or high-value properties. Best for large commercial properties ($10M+), specialized buildings (hospitals, manufacturing, data centers), and situations where institutional partners require on-site documentation. Turnaround is typically 6-12 weeks.

When Cost Segregation Is NOT Worth It (At Any Price)

I will also tell you when cost segregation does not make sense. If your property has a depreciable basis under $150,000 and limited site improvements, the accelerated deductions may be too small to justify even a $499 study. If you are in a low tax bracket (under 22%), the dollar value of accelerated deductions is smaller and the payback period is longer. If you plan to sell the property within 1-2 years, the recapture on sale may offset most of the timing benefit. For a detailed analysis, see our guide on when cost segregation does not make sense.
