Blended Occupancy Cost Calculator
Tenants compare deals on all-in occupancy cost, not base rent. This calculator blends base + NNN + other charges into a single $/SF number so negotiations are apples-to-apples.
Blended occupancy cost per SF
$42.00
NNN subtotal (CAM + tax + ins)
$12.00
NNN as % of base
42.86%
How the math works
Blended occupancy cost includes everything the tenant writes a check for monthly: base + CAM + tax + insurance + utilities + other. Only this number is comparable across lease structures.
A sophisticated tenant will ask 'show me your all-in,' not 'what's your base rent?' Lenders to retailers also stress-test blended OC as % of tenant sales.
How to Use
- Enter base rent PSF.
- Enter CAM, real-estate tax, and insurance reimbursements PSF.
- Enter other charges (utilities, HVAC) PSF.
- Read blended total occupancy cost PSF.
Frequently Asked Questions
Why is this important?
Base rent can be misleading. A $28 base with $14 NNN is $42 all-in; a $38 gross lease might be cheaper. Tenants making real decisions look at the all-in number.
Typical CAM + tax + insurance?
Retail strip center: $8-$18 PSF depending on tax/insurance jurisdiction. Office high-rise: $15-$30+ on top of base. Industrial: $2-$8 (usually NNN is low).
Does occupancy cost ratio matter?
Yes — retail tenants target 8-12% of sales as total occupancy cost. Restaurants: 6-10%. Office: not directly tied to revenue. If tenant OC ratio is too high, they underperform and churn.
