CAM Gross-Up Calculator
When buildings have vacancies, landlords can “gross up” operating expenses to what they would be at full occupancy — but only up to a lease-specified threshold. Misapplication is one of the most common CAM overcharge patterns.
What is gross-up? When building occupancy falls below a lease threshold (commonly 90%), landlords may normalize operating expenses to what they would cost at full occupancy. This protects tenants from subsidizing vacant space — but only works correctly at the right threshold and for variable (not fixed) expenses.
