**The problem it solves** Real estate investors evaluating potential Airbnb or vacation rental acquisitions lack a quick, data-backed way to compare projected short-term and long-term rental returns at a specific address, forcing them to rely on guesswork or pull comp data manually from multiple sources. **What BNBCalc does** BNBCalc is a short-term rental investment analysis platform that generates detailed financial projections for prospective properties by pulling real market data from Airbnb and Vrbo, allowing investors to compare STR and long-term rental scenarios side by side before purchasing. **How it works** Investors enter a property address or paste a Zillow listing link to generate projections instantly. A benchmark engine compares the property against up to 40 local STR comps using live revenue, occupancy, and ADR data. Investors customize mortgage rate, financing terms, operating expenses, and setup costs to model different scenarios. Built-in tax tools calculate bonus depreciation, Section 179 deductions, and other STR-specific tax benefits to show after-tax cash flow. Cap rate, cash-on-cash return, and ROI metrics are presented in a shareable investment report format. A REST API is available for developers and data integrators. **Who it's for** Individual STR property investors, real estate agents working with investor clients, and STR entrepreneurs evaluating new market entry in the US who need data-grounded underwriting to determine whether a property justifies acquisition at a given price and financing structure.
