Break-even occupancy is a monthly number, not an annual one
An annual average that clears break-even can still contain four months that lose money, and those are the months that empty the account.
The short answer
Break-even occupancy is fixed costs divided by the contribution a fully occupied month would produce. It has to be checked month by month, because fixed costs arrive every month while bookings do not, and a listing that averages comfortably above break-even across a year routinely spends the winter below it.
The formula
contribution per night = rate x (1 - platform fee) - consumables + cleaning margin per night
cleaning margin per night = (fee x (1 - platform fee) - cleaning cost) / average stay
break-even nights = monthly fixed costs / contribution per night
break-even occupancy = break-even nights / days in month
If contribution per night is zero or negative there is no break-even occupancy at any level. More bookings deepen the loss, and no amount of marketing fixes a pricing problem.
Worked example
A $175 nightly rate, 6% platform fee, $8 consumables, $95 cleaning charged against $65 paid, 3.5 night average stay, $1,486 of monthly fixed costs:
cleaning margin = (95 x 0.94 - 65) / 3.5 = 6.94 per night
contribution = 175 x 0.94 - 8 + 6.94 = 163.44
break-even nights = 1,486 / 163.44 = 9.09
break-even occupancy = 9.09 / 30 = 30.3%
January at 22% = 6.6 nights x 163.44 = 1,079 → loses 407
July at 90% = 27.0 nights x 163.44 = 4,413 → makes 2,927
The year averages far above 30.3% and looks healthy. January still loses $407, and so does any month that runs below 30.3% no matter how good the summer was.
Why the annual average hides the problem
Fixed costs are monthly and bookings are seasonal, so averaging the year against a single break-even figure quietly nets a profitable August against a loss-making February. The arithmetic works and the bank account does not, because you cannot spend August in February.
This is the mechanism behind most short-let cash flow trouble. The year is fine, the winter is not, and the shortfall gets covered by whatever else the host earns until the year it cannot be.
The months to check first
Your two quietest, and the month a large annual cost lands in. Insurance, licensing and any service charge tend to arrive in the same month each year and are frequently not spread across the model.
A month that is normally comfortable can be the worst month of the year purely because the annual insurance premium falls in it, and that is entirely predictable a year ahead.
What actually moves break-even
Fixed costs, because they are the numerator and they are the part you control outside of the market. Refinancing, dropping a subscription, or renegotiating a cleaning contract lowers the threshold in every month at once.
Average stay length, through the cleaning margin term. A move from 3.5 to 5 nights on the numbers above lifts contribution per night by about $2 and drops break-even by roughly a third of a night a month.
The rate itself does the most per unit change, and it is also the one the market has an opinion about. Which is why fixed costs are usually the honest place to start.
What this leaves out
- Assumes fixed costs are genuinely level across months. Where they are not, run each month against its own figure.
- Excludes tax and licensing, which vary by jurisdiction and can be seasonal in themselves.
- Treats the cleaning fee as retained by the host. Where a manager keeps it, that term disappears and break-even rises.

- What is a good break-even occupancy?
- Lower is better and the useful test is whether your quietest month clears it. If break-even is above about half the month, a normal soft season puts you underwater, and that is a structural problem rather than a marketing one.
- Why is my break-even higher than a similar listing's?
- Almost always fixed costs rather than pricing. Mortgage, service charge and insurance differ enormously between owners of identical flats, and they set the threshold before a single guest is involved.
- Should I close the listing in the loss-making months?
- Only if closing removes cost, which it usually does not. Fixed costs are fixed, so a night booked above zero contribution is better than an empty one even in a losing month. Closing helps when it lets you avoid a variable cost like heating an empty property or paying for a licence period you do not use.
