Use the result with context

Results are estimates for planning and education. Confirm rates, taxes, fees, and legal requirements with the relevant institution or a qualified professional before making a financial decision.

Formula and method

80 occupied rooms out of 100 available rooms give daily occupancy of 80%.

Occupancy (%) = 100 × occupied room-nights / (days × rooms − unavailable room-nights).

Worked example

Assumptions and limitations

  • Daily mode uses one day. Monthly mode always uses 30 days; use custom mode for an actual calendar month with a different length.
  • For multiple days, maintenance input is unavailable room-nights, not merely the number of distinct rooms. Counts are whole and occupied capacity cannot exceed available capacity.
  • Enter all money amounts in one currency. The retained currency conversion menu uses captured historical conversion factors, not current exchange quotes.
  • Clear an unknown editable field before solving an inverse; fixed selections and output-only fields cannot be inferred.

What does this calculation assume?

Daily mode uses one day. Monthly mode always uses 30 days; use custom mode for an actual calendar month with a different length.

Are these current exchange rates?

No. Use one currency consistently; currency menu factors are a historical snapshot.
