Estimate your tax savings in seconds.
Most calculators inflate one flat percentage of your purchase price to win the comparison. We model your real property and land split, so your estimate reflects the tax savings a full study would actually find.

Your estimated tax savings
If this looks lower than the other calculators you tried, that is the point. They inflate one flat percentage of your purchase price to win the comparison. This is a real, property-specific estimate, grounded in your actual property instead of a flat formula.
Adjust assumptions Price, tax rate, rental type
Adjust the price or tax rate if the public estimate looks off and your savings update instantly. Tax rate accepts either 37 or 0.37.

With a study
"Without a study" assumes standard straight-line depreciation. A study reclassifies part of your building into shorter-life property you can deduct sooner.

Why this number is different
The calculator you used before probably overpromised.

Cost segregation calculator questions, answered
How accurate is a cost segregation calculator?
It's an estimate built from your property's real data, so it lands in a realistic range, but it's still a projection. The full study verifies everything against your actual photos and closing documents, and that's the number your CPA files from. Never file a return based on any calculator output alone.
Is the calculator really free?
Yes. There's no charge and no account to create: you enter your email to see your full results, and that's it. You only ever pay if you decide to order the $799 study.
What information do I need to use it?
Just the property address. The calculator pulls the rest and lets you adjust the purchase price, land allocation, and tax rate so the estimate reflects your actual situation.
What's the difference between the calculator and the $799 study?
The calculator projects your likely savings in about a minute. The study is the real thing: a documented, audit-supported report built with our engineering-based approach, delivered in 2 business days, with the schedules and support detail your CPA needs for Form 4562 or Form 3115.
