Measure occupied units or occupied time against total available capacity.
It keeps income, operating costs, financing, invested cash, value, timing, and exit assumptions explicit so you can reproduce the result and compare genuinely consistent scenarios.
Calculation structure
Keep income, costs, and value in the right period
Occupancy rate = occupied units or time ÷ total available units or time × 100%. Vacancy rate = 100% − occupancy rate.

Potential incomevacancy−operating costsCollected incomeKeep capacity and reporting periods consistentOccupancy rate = occupied units or time ÷ total available units or time × 100%. Vacancy rate = 100% − occupancy rate.
Read the result correctly
Use the result with its boundaries
Ninety occupied unit-months out of 100 available unit-months produce 90% occupancy and 10% vacancy.
Use a consistent capacity basis, such as rooms, unit-days, or unit-months. The calculator does not infer blocked or out-of-service inventory.
Quick guide
How to use this calculator
Enter property amounts from one consistent currency and period.
Use the labels to match the calculator's stated income, cost, area, or capacity convention.
Read the assumptions beside the result before using it in an investment comparison.
Calculation method
Calculation method
Occupancy rate = occupied units or time ÷ total available units or time × 100%. Vacancy rate = 100% − occupancy rate.
Entered fixed decimals use exact rational arithmetic. Money rounds only for display; a supported nonzero amount is never replaced by a misleading zero.
Worked example
Worked example
Ninety occupied unit-months out of 100 available unit-months produce 90% occupancy and 10% vacancy.
Occupancy rate = occupied units or time ÷ total available units or time × 100%. Vacancy rate = 100% − occupancy rate.
Supported inputs
Precision and limits
Visible input limits
Amounts accept up to 30 digits and 12 decimal places and are capped at 1e12 per input. Rates are capped at 1000%; signed value-change rates cannot be below −100%.
International scope
No currency, tax regime, tenancy law, lender threshold, local market database, appraisal standard, or jurisdiction-specific fee is assumed.
Decision boundary
The result is an arithmetic scenario based on visitor-entered figures, not an appraisal, forecast, lending decision, legal determination, or investment recommendation.
Calculator-specific assumptions
Use a consistent capacity basis, such as rooms, unit-days, or unit-months. The calculator does not infer blocked or out-of-service inventory.
