How Much Can a Cost Segregation Study Save You? The Numbers Explained

The question every property owner asks is simple: is this actually worth it?

The answer depends on your property value, property type, tax bracket, and how long you have owned the property. This article walks through how the math works and what realistic savings look like for different scenarios.

How the Savings Are Calculated

A cost segregation study does not create new deductions. It accelerates deductions you were already going to take over 27.5 years and moves a significant portion of them into the first 5 to 15 years. The savings come from the time value of money: claiming $50,000 of depreciation in year one is worth more than claiming it in year 20.

The actual tax savings in year one depend on how much of your cost basis gets reclassified into shorter recovery periods and what tax rate those deductions reduce.

A Concrete Example

Take a single-family rental purchased for $450,000 with a $50,000 land value, giving a depreciable basis of $400,000.

Under the standard 27.5-year schedule, the annual depreciation is about $14,545 per year.

After a cost segregation study, a typical result might look like this:

The 5-year and 7-year personal property qualifies for MACRS accelerated depreciation. Combined with the 15-year land improvements, a significant portion of the reclassified amount can be deducted in year one instead of being spread over 27.5 years.

For an investor in the 32% tax bracket, a first-year writeoff of $60,000 to $80,000 above the standard depreciation translates to roughly $19,000 to $25,000 in actual tax savings in year one alone.

What Affects How Much Gets Reclassified

Several factors determine how much of your cost basis qualifies for shorter schedules:

Furnished vs. unfurnished. Short-term rentals and furnished properties typically have significantly more 5-year personal property. Furniture, appliances, and decorative items all qualify for shorter schedules and are present in higher quantities in furnished units. A fully furnished Airbnb will almost always produce a larger reclassification than an unfurnished long-term rental at the same price point.

Short-term rental tax treatment. STR investors who materially participate (100+ hours per year) and have an average guest stay of 7 days or less may be able to apply the accelerated depreciation against W-2 or business income, not just passive rental income. This makes the effective value of the deduction significantly higher for high-income earners. Your CPA determines whether you qualify for this treatment.

Property age and condition. Newer properties or recently renovated properties with updated fixtures, flooring, and finishes tend to have more reclassifiable components at higher values.

Outdoor features. Properties with driveways, patios, landscaping, pools, and fencing have more 15-year land improvement components, which can add up quickly.

Property value. In general, higher-value properties have more absolute dollars to reclassify, even if the percentage is similar.

The ROI Calculation

At a flat study fee, the return on investment is straightforward to calculate. If the study produces $25,000 in first-year tax savings, the ROI is substantial and the payback period is essentially immediate.

Even conservative scenarios, where only a modest amount gets reclassified, typically produce savings that far exceed the cost of the study in the first year.

Recapture: The Honest Picture

One thing worth understanding: when you sell the property, depreciation recapture applies. The IRS taxes the accelerated depreciation at up to 25% under Section 1250.

However, you are not being taxed on deductions you did not take. Standard 27.5-year depreciation is also subject to recapture. The question is simply whether the time value of larger deductions today outweighs the recapture tax years later. In nearly every scenario at normal interest rates and holding periods, the math favors acceleration.

Many investors also address recapture through a 1031 exchange when they sell, deferring both capital gains and recapture taxes indefinitely.
