Annual CAM pool (center total) ($)Administrative fee (%)Your suite (SF)Center leasable area (SF)

Pro-rata share: 6.97%
Your CAM, per year: $9,194
Your CAM, per month: $766/mo
Per square foot, per year: $4.38/SF

Your CAM = CAM pool × (1 + admin fee) × (your SF ÷ the center’s leasable SF). Leases differ on what the pool includes and whether the denominator is leased or leasable area. The example figures are illustrative, not the terms of any property.
