“Is an Airbnb worth it?” usually gets answered with a nightly rate — “$180 a night, of course it’s worth it.” But nightly rate alone tells you almost nothing. A property at $180 a night at 65% occupancy earns a RevPAR (revenue per available night) of $117 and roughly $42,705 a year in room revenue — and whether that’s a good deal depends entirely on whether it clears the occupancy you need just to cover costs. Short-term rental ROI lives in three metrics — ADR, occupancy, and RevPAR — measured against break-even occupancy.
The one-number answer: RevPAR
If you only look at one number, make it RevPAR — revenue per available night. It blends how much you charge (ADR) with how often you’re booked (occupancy), so it can’t be gamed by either one alone.
That matters because the two obvious levers pull against each other. Drop your nightly rate and occupancy usually rises; push the rate up and occupancy falls. ADR and occupancy on their own can each look great while the deal underperforms. RevPAR settles the argument: a host running $250 ADR at 40% occupancy (RevPAR $100) is earning less per available night than one at $150 ADR and 75% occupancy (RevPAR $112.50), despite the lower headline rate.
ADR, occupancy and RevPAR explained
| Metric | Question it answers | Formula |
|---|---|---|
| Occupancy | How often am I booked? | Nights booked ÷ nights available |
| ADR | What do I earn per booked night? | Room revenue ÷ nights booked |
| RevPAR | What do I earn per available night? | ADR × occupancy |
- ADR (average daily rate) is your realised price per booked night — after discounts and length-of-stay deals, not your headline rate.
- Occupancy is the share of available nights you actually filled.
- RevPAR is the one to compare across periods and against other deals, because it captures both at once.
These three sit alongside the universal property metrics — gross yield, net yield, cap rate, and cash-on-cash. If those terms are new, property ROI metrics explained covers them. STR just adds the occupancy-driven layer on top.
Break-even occupancy
The reality check on any Airbnb is break-even occupancy — the fill rate you need just to cover costs:
Break-even occupancy = annual costs ÷ (ADR × nights available)
If your costs are $30,000 a year and your ADR is $180, you need to cover $30,000 ÷ ($180 × 365) ≈ 46% occupancy before you make a cent. If your market realistically runs at 55%, you have a thin margin. If it runs at 40%, the deal loses money no matter how good the listing looks. Comparing break-even occupancy to the occupancy your area actually achieves is the single most honest “is it worth it?” test there is.
Worked example
Take a $400,000 property let as a short-term rental at $180 ADR and 65% occupancy:
| Line | Amount | How it’s derived |
|---|---|---|
| Nights booked | ~237 | 365 × 65% |
| Room revenue | $42,705 | 237 × $180 |
| RevPAR | $117 | $180 × 65% |
| Cleaning (per booking) | -$4,740 | ~79 stays × $60 |
| Platform fees (3%) | -$1,281 | 3% of revenue |
| Occupancy levy (per night) | -$948 | 237 × $4 (pass-through) |
| Other operating costs | -$11,000 | utilities, insurance, management, maintenance, rates |
| Net operating income | ≈ $24,700 | revenue − costs (excl. pass-through) |
| Cap rate | ≈ 6.2% | NOI ÷ $400,000 |
Break-even occupancy here is roughly 27% (about $18,700 of cost ÷ ($180 × 365)), comfortably below the 65% assumed — so on these numbers the deal works. Change one input, though, and it can flip: at 45% occupancy room revenue falls to about $29,565, NOI compresses sharply, and the margin over break-even thins. That sensitivity is exactly why you model it rather than eyeball the nightly rate.
These figures are illustrative — your purchase costs, financing, and local taxes change the answer, which is the point of running it for your own property and country.
STR vs long-term let
Whether an Airbnb beats a standard buy-to-let comes down to a trade-off:
- STR upside: higher gross revenue per night and pricing flexibility (raise rates for events and peak season).
- STR cost: much higher operating load — cleaning per booking, supplies, higher management fees, and bigger swings between peak and off-season.
- Long-term let: lower and steadier revenue, far lower operating cost, and far less of your time.
A short-term rental is “worth it” when the RevPAR premium over local long-term rent clears those extra costs and compensates you for the work. If you’re weighing property against other asset classes entirely, is buy-to-let worth it in 2026? takes the wider view.
How to run your own numbers
Illustrative numbers only get you so far — your country’s purchase costs, transfer tax, and financing change the ROI. Run your own deal:
- Open the short-term rental calculator and pick your country.
- Enter purchase price, nightly rate, occupancy, expenses, and financing with the Airbnb property type.
- Read ADR, RevPAR, occupancy, and break-even occupancy alongside yield and cash-on-cash.
- Export the workbook to track actuals against the plan.
Then keep score: how to track Airbnb income and expenses and the free Airbnb / short-term rental spreadsheet template cover the monthly routine, and what’s inside the exported workbook shows where every number lives.
