Break-even occupancy tells you how many booked nights a property needs before it produces a dollar of cash flow. It is a more useful first screen than a headline revenue estimate because it connects nightly rate to the actual cost of owning and operating the property.
The formula
Start with monthly fixed costs: debt service, property tax, insurance, internet, software, minimum utilities, and any HOA dues. Then estimate the contribution from each booked night: average nightly revenue minus the costs that rise with a booking, such as platform fees, consumables, utilities, and any cleaning shortfall. Divide fixed costs by contribution per night. Divide the resulting nights by the number of nights available in the month.
Break-even booked nights = monthly fixed costs ÷ (average nightly revenue − variable cost per booked night). Break-even occupancy = booked nights ÷ available nights.
Use revenue after discounts and refunds. Treat cleaning fees and cleaning bills consistently: either include both in revenue and expense or exclude both when they offset one another.
A worked example
Suppose fixed monthly costs are $5,400, an achievable average nightly rate is $300, and booking-related costs average $60 per night. Each booked night contributes $240. The property needs 22.5 booked nights, which means at least 23 nights in a 30-night month, or roughly 77% occupancy, to break even on cash flow.
If the same property can realistically fill only 18 nights in a typical month, the answer is not to assume a better listing will solve the gap. Test a lower purchase price, a smaller debt payment, a higher justified rate, or reject the deal. The example is arithmetic, not a market forecast.
Test the weak months
Annual average occupancy hides the calendar. A beach home can be profitable for the year but still need cash injections in winter. Run this formula month by month with season-specific rates and available nights. Carry a reserve for months below break even.
For a more complete investment view, add recurring capital replacements and management fees. A property that only breaks even before those costs has no economic margin. Compare the result with the revenue projection guide and the STR calculator.
Frequently asked questions
What is a good break-even occupancy for an Airbnb?
There is no universal target. A lower break-even point gives a larger margin for weak months, but the right threshold depends on seasonal demand, nightly rates, financing, and operating costs.
Should cleaning fees count in break-even occupancy?
Yes, if you include guest cleaning fees as revenue, include the actual cleaning expense too. Excluding both is acceptable when they approximately offset, but do not count the fee and omit the cost.
