About STR ROI Calculator
STR ROI Calculator was built because the tools available to short-term rental investors were either too simple (nightly rate calculators that ignored real costs) or too opaque (proprietary platforms that didn't show their work). We wanted something different: institutional-grade analysis, completely transparent, completely free.
Every formula we use is documented on our Methodology page. Every input is editable. Every calculation updates in real time as you type. We don't sell leads to lenders, we don't have a preferred outcome, and we don't hide the math.
Our calculator models the six metrics every serious STR investor uses: gross annual revenue, NOI, cash-on-cash return, cap rate, break-even occupancy, and DSCR. It also generates 5-year equity projections and integrates with live market data from 55+ US cities so you can pre-populate with real numbers instead of guesses.
For investors who want a more complete analysis, we offer AI-powered Investor Reports ($9.99) and Pro Audits ($19.99) — institutional-grade PDFs generated by Claude (Anthropic's AI model) using your specific inputs. These reports are delivered within minutes and include risk assessment, scenario analysis, financing recommendations, and revenue optimization strategies.
We are not a brokerage, lender, or property management company. We don't receive commissions on deals, and our only revenue comes from report sales and clearly labeled sponsored tool recommendations. Our analysis has no agenda other than giving you accurate information.
Why We Built the AI Report
Professional STR analysis used to cost $300–500/hour
Before this tool existed, investors who wanted a thorough short-term rental investment analysis had two options: spend 4–6 hours building their own spreadsheet model — researching market occupancy data, modeling multiple revenue scenarios, analyzing financing options, and writing up a coherent summary — or hire a real estate consultant at $300–500 per hour. A full analysis from a qualified analyst typically runs $1,200 to $3,000 and takes several days to deliver.
Most individual investors did neither. They made decisions based on incomplete data, optimistic projections from listing platforms, and gut instinct. The result: preventable surprises — break-even occupancy assumptions that were 15 percentage points too low, operating expenses that were half of reality, and deal underwriting that only looked good on paper.
Our AI reports change that equation. For $9.99, an investor gets the same depth of analysis that would take a professional analyst half a day to produce: executive summary verdict, revenue projection with market context, risk factors, 5-year equity model, and an optimization roadmap. The Pro Audit at $19.99 adds three-scenario analysis, DSCR loan qualification, amenity ROI recommendations, a seasonal revenue calendar, and platform fee strategy. Both are delivered in under 2 minutes. Both can be shared directly with a lender, business partner, or financial advisor. Institutional-grade analysis should not be a luxury reserved for institutional buyers.
