See how Stowlane works →Monthly revenue is your occupied units (unit count × occupancy) multiplied by average rent. Annual revenue is that figure across twelve months. Net operating income (NOI) subtracts your operating-expense ratio — taxes, insurance, utilities, payroll, maintenance, and software — from revenue; it's the number lenders and buyers care about. RevPAU (revenue per available unit) is annual revenue spread across every unit, occupied or not, and is the cleanest way to compare facilities of different sizes.
These are planning estimates, not a substitute for your actual books. Real facilities vary by climate control, unit mix, market rents, and delinquency.
