Airbnb hosts and investors can now calculate short-term rental cash flow with HostMath's new profit calculator. The tool allows users to input nightly rate, occupancy, and real running costs to instantly see net cash flow per month, net margin, break-even occupancy, and break-even nightly rate. A one-time $10 unlock reveals the full analysis for a single property, including cost breakdowns and payback periods for furnishing spend.
The calculator operates entirely within the browser, ensuring no user data is stored or sent. The preview is free, offering all 16 live inputs and the formulas behind every figure, while the detailed results require the $10 unlock. The tool clarifies fee structures, distinguishing between Airbnb's default 3% host-only service fee and the 14-16% split-fee model.
It also explains how cleaning fees count as both revenue and cost. The calculator excludes income tax, sales tax, and one-off replacements like roof or HVAC. It provides a year-at-a-glance average, noting it is an estimate, not tax, legal, or financial advice.
Users can see exactly how figures are derived from public formulas, making it a transparent tool for real estate investment analysis.
