HostMath – Airbnb profit calculator with break-even occupancy and payback
HostMath is a browser-based calculator designed for Airbnb hosts to estimate profitability, break-even points, and payback periods. The tool emphasizes privacy by performing all calculations locally in the user's browser without storing data.
Why it matters
It provides a niche financial tool for the gig economy, specifically targeting short-term rental investors looking for transparent, non-tracking analysis.
Short-term rental profit calculator for US hosts and investors
Type in your nightly rate, occupancy and real running costs and the calculator works on your numbers straight away: every input is live, and you can see exactly which figures it produces and how each one is derived. The figures themselves — net cash flow per month, net margin, break-even occupancy and nightly rate, and how long your furnishing spend takes to pay back — come with the $10 unlock for one property . Nothing is sent to us and nothing you type is stored.
Enter your own numbers — nothing here is a US average and nothing is saved. Every input below is free to use and changes nothing about what you are charged.
The share of your available nights that actually get booked.
Airbnb's host-only fee is 3%. On split-fee listings hosts pay roughly 14–16%.
