Assumptions: These are estimates, not a forecast or tax advice. USD/GBP changes the currency label only, not exchange rates. Enter figures in one currency throughout. Check platform fees, taxes and local rules before making a decision.

How to use the results

Break-even occupancy is the number to watch. If your forecast is only a few points above it, one slow month or a rate cut puts the unit into a loss. A healthy unit has room to spare.

RevPAR (revenue per available night) combines rate and occupancy, so you can compare units of different sizes or pricing strategies on one number.

Pre-tax operating profit only. It does not include income tax, depreciation or loan principal. For UK holiday lets, remember that the furnished holiday lettings tax rules ended in April 2025, which changes after-tax returns for many owners.

Common questions

What is a good profit margin for a short-term rental?

It depends on whether you own, lease or manage the unit. Rental arbitrage units carry rent as a fixed cost, so margins are usually thinner than for owned units. Use the break-even occupancy figure to judge risk: the further your forecast occupancy sits above break-even, the safer the unit.

How is break-even occupancy calculated?

The calculator finds the occupancy at which revenue after percentage costs (channel commission, management fee, taxes collected) and per-stay costs (cleaning, supplies) exactly covers your monthly fixed costs.

Should I include taxes in the calculator?

Only include taxes that come out of your revenue, such as a lodging or occupancy tax you collect and pay over, or VAT if your prices include it. Leave the field at zero if guests pay taxes on top of your price. This is not tax advice.
