Is This a Calculator or Do I Have to Wait for Results?

This is an instant calculator. You get results in 30-60 seconds, with no waiting, no sales calls, and no email required upfront. The output shows estimated depreciation breakdowns, tax savings, and all underlying assumptions (which you can adjust and recalculate). Think of it as an interactive Excel model powered by AI and real market data.

Can I Change the Assumptions and See Different Scenarios?

Yes! All assumptions are visible and editable in your report: property type, construction cost, land value, tax rate, reclassification percentages, and more. Adjust any field and the calculator instantly recalculates your depreciation schedule and tax savings. You can model multiple scenarios side-by-side.

Is This an IRS-Ready Study or an Estimate?

This is an estimate for planning and decision-making. It's built on AI analysis and data from 1,000+ actual studies, but it's not an IRS-defensible engineering report. For that (with site visits, detailed asset tagging, and audit defense), schedule a consultation with our engineering team. Think of this calculator as 'step 1' to understand if a full study makes sense for your property.

How Does the Calculator Get Property Data?

Our AI automatically pulls data from 15+ external sources: broker listings, property photos, county/state assessor records, satellite imagery, construction databases, and public statistics. You can override any auto-filled data. For the most precise outcome, we suggest a free consultation where we walk through your property's specific features together.

Audit-ready support matters

Our approach draws on the published guidance of James C. Peacock, former IRS General Engineer and contributor to the IRS Cost Segregation Audit Technique Guide, which focuses on what supports the numbers: land allocation, RS Means detail, site evidence, and asset classification.
