Why short-term rentals need their own math
A long-term rental has one revenue line and mostly fixed costs. A short-term rental is closer to a small hospitality business: revenue is ADR × 365 × occupancy, and a large share of costs scale with every booking. Running an Airbnb through a standard rental calculator will overstate the return badly, because it misses the platform fee, per-turnover cleaning, host-paid utilities, and the furnishing bill.
The fee change most calculators missed. On 27 October 2025 Airbnb moved to a single host-only fee model: hosts now pay about 15.5%, deducted from payouts, and guests are no longer charged a separate platform fee. The old split model charged hosts roughly 3%. Any tool still assuming 3% will materially overstate your income — this calculator defaults to 15.5% and lets you override it.
Break-even occupancy is the number that matters. Rather than trusting an optimistic ADR, ask what share of nights you must actually book to cover everything. Fixed costs — mortgage, taxes, insurance, utilities, supplies — divided by the contribution margin left after variable costs gives you a single threshold to test. If break-even lands at 62% and comparable listings in your neighbourhood run 50–55%, the deal fails regardless of how good the headline rate looks. Test it against comparable active listings near you, not a national average.
Don't forget furnishing, management, and rules. Furnishing is real cash spent before your first guest, so it belongs in the cash-on-cash denominator alongside the down payment. Full-service STR management runs 20–25% of revenue versus 8–12% for long-term — model it even if you self-manage, so the deal isn't secretly dependent on your unpaid labour. Finally, check local rules: many cities permit-gate, restrict, or ban short-term rentals, and lodging taxes vary. The calculator also compares your STR against the same property as a conventional rental — sometimes the quieter option wins.
This page prices the cost structure of a short-term rental — platform fee, per-turnover cleaning, management, furnishing — and computes the break-even occupancy your specific numbers require. It deliberately does not publish a national occupancy or ADR figure: no dataset in this site's source registry verifies one, so none is asserted here. Compare your own break-even against comparable active listings you can actually see.
Why this page won't give you an occupancy number
Most short-term-rental content publishes a national average occupancy or ADR figure. This one doesn't, on purpose. Neither figure has a verifiable primary source behind it in this site's research — the industry data that circulates (from booking platforms, listing aggregators, and STR-specific analytics firms) is proprietary, sampled inconsistently, or simply not published as a citable dataset the way a government release is. Rather than round a marketing statistic into something that looks authoritative, this calculator asks you to supply your own ADR and occupancy — ideally taken from comparable active listings you can see directly, not a citywide average that may not describe your neighborhood, property type, or season at all.
What this calculator does compute reliably is the break-even occupancy your own inputs require — the threshold at which your specific cost structure stops losing money — because that's arithmetic on numbers you control, not a market estimate borrowed from somewhere unverifiable.
A full worked example
A $310,000 property, 20% down ($62,000), $9,000 closing costs, $18,000 furnishing, financed at the Freddie Mac 30-year average of 6.71% (week ending September 3, 2026). Suppose a host models a $220 ADR at 55% occupancy — a scenario input, not a benchmark — with a 4-night average stay, $120 cleaning per turnover, the current 15.5% Airbnb host-only platform fee, 20% short-term management, $800/year supplies, $2,400/year utilities, and $6,200/year in fixed costs (tax, insurance, HOA).
Break-even occupancy on these same numbers: fixed costs ($19,222 debt service + $800 + $2,400 + $6,200 = $28,622) divided by the contribution margin per full year of occupancy ($220 × 365 × (1 − 0.355) − (365 ÷ 4) × $120 = $40,844), giving a break-even of about 70.1%. The modeled 55% occupancy sits well below that — which is exactly why the cash flow above came out negative. That gap, not the revenue figure, is the number that should decide whether this specific deal is worth pursuing.
What the same property would do as a long-term rental
The calculator runs the identical property as a conventional long-term rental for comparison. At a $1,750/month comparable rent and 5% vacancy: effective gross rent = $1,750 × 12 × 0.95 = $19,950. Less 10% long-term management ($1,995) and the same $6,200 in fixed costs, NOI comes to $11,755. Against the identical $19,222 in annual debt service, that's an annual cash flow of −$7,467 — worse than the STR's −$6,158 by about $1,309/year in this scenario, though neither configuration clears zero on these particular assumptions. Whichever property you're modeling, that comparison is the point: run both, and let the gap between them — not either number alone — inform the decision.
For context on the comparable long-term rent input specifically: the national rental vacancy rate was 7.3% and the median asking rent was $1,531 in the Census Bureau's Q2 2026 Housing Vacancy Survey, and rent of primary residence rose 2.9% over the 12 months to July 2026 per BLS CPI. Those are national figures, not a substitute for a local comp — use them only as a rough sanity check on a long-term rent assumption, never as the number itself.
Methodology
Revenue, cost, cash flow, cap rate, cash-on-cash, break-even occupancy, and the long-term-rental comparison are computed exactly as this calculator's own module does, using this article's own stated scenario inputs — none of which is presented as a market benchmark. The mortgage payment uses standard 30-year fixed amortization at the Freddie Mac PMMS 30-year average for the week ending September 3, 2026. The 15.5% platform fee is this calculator module's own documented constant. National rent and vacancy figures (Census HVS Q2 2026, BLS CPI) are cited only as context for the long-term-rental comparison's rent input, not as a short-term rental benchmark — no occupancy or ADR figure is sourced anywhere in this article because none could be verified.

Short-term vs long-term rental: the cost differences
| Cost | Short-term rental | Long-term rental |
|---|---|---|
| Platform fee | ~15.5% (Airbnb host fee since Oct 2025) | None |
| Management | 20–25% of revenue | 8–12% of rent |
| Cleaning | Every turnover | Between tenants only |
| Utilities | Host pays | Tenant usually pays |
| Furnishing | Large one-time cost | None (unfurnished) |
Airbnb's single host-only fee replaced the old ~3% host share on 27 Oct 2025.
Frequently asked questions
What is break-even occupancy and why does it matter?
Break-even occupancy is the percentage of nights you must book for the property to cover all its costs — mortgage, taxes, insurance, utilities, supplies, plus the variable platform, management, and cleaning costs. It's the most useful number in short-term rental analysis because it converts a pile of assumptions into a single testable threshold. If your break-even is 62% and comparable listings in your area run 50–55% occupancy, the deal doesn't work no matter how attractive the ADR looks.
What does Airbnb charge hosts?
Airbnb moved to a single host-only fee model on 27 October 2025. Hosts now pay approximately 15.5%, deducted from payouts, and guests are no longer charged a separate platform service fee. This replaced the older split model where hosts paid roughly 3% and guests paid the rest. Because the fee is now a much larger share of host revenue, it materially affects short-term rental returns — older calculators using a 3% assumption will significantly overstate your income.
Why does furnishing cost belong in the return calculation?
Furnishing is real cash out of your pocket before a single guest arrives — furniture, linens, kitchenware, electronics, photography, smart locks. It's the cost long-term-rental investors never face. Because cash-on-cash return divides annual cash flow by total cash invested, leaving furnishing out of the denominator inflates your apparent return. This calculator includes it alongside your down payment and closing costs.
What occupancy should I assume?
Use comparable active listings near you rather than a national number. Occupancy depends on your specific neighbourhood, property type, and how actively you manage pricing, and ADR and occupancy trade off against each other.
Why is short-term rental management so much more expensive?
Full-service short-term rental managers typically charge 20–25% of revenue, versus 8–12% for a long-term rental. The work is genuinely different: guest communication, dynamic pricing, turnover coordination, restocking, and round-the-clock support. Even if you plan to self-manage, it's worth modelling a management fee — a deal that only works because you do the labour yourself is more fragile than it appears, and it caps how far you can scale.
Is a short-term rental always better than a long-term rental?
No. Short-term rentals can generate more gross revenue, but they carry higher costs (platform fees, management, cleaning, utilities, furnishing), far more workload, more income volatility, and real regulatory risk — many cities restrict, permit-gate, or ban short-term rentals, and rules change. This calculator compares your projected short-term cash flow directly against the same property as a conventional rental so you can see whether the premium actually justifies the extra risk and effort.
