Break-Even Occupancy for Short-Term Rentals

Break-even occupancy estimates how many available nights must be booked for contribution margin to cover fixed monthly costs. It is especially useful when a strong gross-revenue forecast hides a narrow operating margin.

What Break-even occupancy means

Each occupied night contributes the average daily rate minus variable per-night costs. That contribution must first cover mortgage and other fixed costs before the property produces positive monthly cash flow.

FormulaBreak-even occupancy = fixed monthly costs / (available nights x contribution per occupied night)

Contribution per occupied night equals average daily rate minus platform fees and other costs that rise with a booking night.

Separate fixed and variable costs consistently. Cleaning charged to guests may still have unrecovered labor, supplies, or turnover costs.

Break-even occupancy example

  • Fixed monthly costs: $4,200
  • Average daily rate: $225
  • Variable cost per occupied night: $45
  • Available nights: 30

Result: $4,200 / (30 x $180) = 77.8% break-even occupancy.

When investors use it

  • Stress-testing a short-term rental
  • Comparing monthly seasonality
  • Evaluating a management or platform-fee change
  • Testing whether a long-term-rental fallback is safer

Common mistakes

  • Using gross nightly rate as contribution margin
  • Assuming all calendar nights are legally and practically available
  • Ignoring seasonal price changes
  • Treating annual average occupancy as proof that every month covers fixed costs

Frequently asked questions

Should mortgage payment be included in break-even occupancy?

Include it when the goal is cash-flow break-even. Exclude financing only when measuring property-level operating break-even before debt.

How do cleaning fees affect the calculation?

Include only the net cleaning contribution or cost retained by the owner. A guest-paid fee is not automatically profit.

Why calculate break-even by month?

Seasonality can make an annual average look safe while low-season months require substantial reserves.
