Airbnb / STR break-even occupancy calculator

Find the occupancy rate you need so contribution after the Airbnb host fee and variable costs covers your fixed costs (plus an optional target). Also shows cushion vs your expected occupancy and a price-floor sketch at that occupancy. Free, no signup, runs in your browser. Arithmetic last checked against our live Break-Even pack formulas on 2026-10-03.

1 · Stay economics

Net revenue after fee = (nights × ADR + cleaning) − fee on the fee base. Default host fee 15.5% single fee.

2 · Variable costs (per stay)

Variable per stay = cleaning cost + other per-stay + (per-night × nights). These are costs you pay when a stay books — not fixed overhead.

3 · Fixed costs & capacity

Fixed costs do not change with bookings. Expected occupancy is your number from your history or plan — not a market forecast from this page.

4 · Break-even results

5 · Price-floor sketch (at your expected occupancy)

Solves for the lowest ADR that still meets fixed + target at your expected occupancy, holding cleaning collected and variable costs constant. Price and occupancy move together in reality — use this as arithmetic, then stress-test.

What the numbers mean

Questions

How is break-even occupancy calculated?

Booked nights needed = (annual fixed costs + target profit) ÷ contribution per booked night. Break-even occupancy = those nights ÷ nights you make available. Contribution per booked night is net revenue after the host fee minus variable costs, divided by stay length. Same structure as our Break-Even & Cancellation Pack and common STR underwriting write-ups (sources 1–3).

Does Airbnb publish a break-even occupancy number?

No. Airbnb publishes the host service fee (Help 1857 / Resource Center). Occupancy break-even is host-side planning arithmetic using your costs and prices.

Should I include mortgage principal?

Include every cash outflow you treat as unavoidable for the year you are modelling (many hosts include full mortgage payment, insurance, property tax, HOA, base utilities, and software). This tool does not separate interest vs principal or depreciation — talk to a qualified professional for tax treatment.

Is my data sent anywhere?

No. The arithmetic runs in your browser; nothing you type is transmitted or stored.
