Your break even point is the booked nights needed to cover the costs you include. This calculator divides monthly fixed cash costs by the money left from each booked night after the entered fees and variable costs. It also shows whether enough nights are available to reach that result.
What you enter
Enter the number of calendar nights in the month, owner blocked nights, expected average room revenue per booked night and costs that rise with bookings. Keep monthly mortgage payments, taxes, insurance, HOA dues and other fixed cash bills together in the fixed cost field.
Enter management and platform charges as separate percentages only when both apply to the same room revenue basis. If they use a different basis, convert them into dollar costs first. A cleaning fee charged to the guest and the cleaning bill paid to the cleaner are separate entries. Do not assume they cancel.
If you charge by stay, enter average stay length so the tool can translate those amounts into an average cost per booked night. The result is a planning average. It does not predict the actual mix of bookings.
Example
Assume $4,000 in fixed monthly cash costs, $250 in room revenue per booked night, a combined 20% of that revenue for entered percentage costs, and another $40 in variable costs per booked night. These are made up inputs, not actual platform fees or management terms.
The contribution from each booked night is $160: $250 less $50 of percentage charges and $40 of variable costs. Divide $4,000 by $160 and you need 25 booked nights to cover the included costs.
In a month with 30 available nights, that is about 83.33% occupancy. If five nights are blocked for your use, 25 nights remain available. The same required bookings then consume every available night. Blocking those dates changes the practical room for error even though the bills stayed the same.
What occupancy do I need to break even?
Divide required booked nights by available rental nights. Check the booked night count alongside the percentage, because the denominator changes when you block dates.
This is cash break even under your inputs. It is not a lender coverage test or a tax profit calculation. See Airbnb Break Even Occupancy: Required Booked Nights for the longer investment discussion.
How do rate, fees and costs change it?
A higher nightly contribution reduces the nights needed. Higher fixed costs or higher charges on each booking increase them.
Use an average nightly rate after discounts rather than a holiday asking price. The calculator cannot tell whether the rate you enter is achievable.
How many booked nights is that?
The tool shows both the exact mathematical result and the next whole night. You cannot book a fraction of a night to cover a monthly shortfall.
If the result exceeds available nights, the entered scenario cannot cover those costs within that month. It needs different revenue, costs or cash support.
What if taxes or insurance rise?
Add the increased monthly cost to the fixed bills and rerun it. Keep the original result so you can see how many additional nights the change would require.
