Occupancy cost percentage is the sum of rent, property taxes, building insurance, and the building-tied share of utilities, expressed as a percentage of total sales.
Formula: Occupancy cost % = (Rent + Property Tax + Building Insurance + Utilities) ÷ Total Sales × 100
For full-service independent restaurants, the operational ceiling is 6–8% of sales. The NRA's 2024 Restaurant Operations Data Abstract reports a full-service median of 5.7% and a limited-service median of 5.2%. The healthier operators run below the median; struggling concepts often locked in lease terms above 8% during the build-out and never recovered the margin.
Above 10%, occupancy cost is structural — the concept needs higher check averages or higher cover counts than the location can deliver. Below 5%, occupancy cost is competitive; the operator either negotiated well or the local market is soft.
Unlike food cost or labor cost, occupancy cost is largely fixed at lease signing. Small annual escalators (typically 2–4%) compound, but the structural ratio is set on day one. An operator who signs a lease at a price that yields 9% occupancy at projected sales is permanently constrained — every dollar of variable cost has to fit underneath. Operators who signed at 5–6% have the room to run a more generous menu, hire better staff, or absorb a slow quarter.
Example: $4,500 base rent + $800 CAM + $600 property tax pass-through + $300 building insurance + $1,400 utilities = $7,600 monthly occupancy. Against $115,000 monthly sales: $7,600 ÷ $115,000 × 100 = 6.6% — at the upper edge of the operational band.
