What is Sales Per Square Foot?
A retail performance metric calculated by dividing total annual sales by the total square footage of the retail space.
Definition
Sales per square foot (Sales/SF) is the most widely used benchmark for retail performance and site selection feasibility. It represents the revenue-generating efficiency of a retail space and varies significantly by category — a jewelry store may generate $1,000+/SF while a dollar store generates $150-200/SF. In site selection, Sales/SF benchmarks are used to project revenue potential for a specific location by multiplying the benchmark by the proposed premises size. This projection then feeds into occupancy cost analysis to determine whether the location can support the asking rent. National average Sales/SF data is published by industry organizations like ICSC and compiled by platforms like Slant. Location-specific factors (trade area demographics, foot traffic, competition) cause actual performance to deviate from national averages, so benchmarks should be used as starting points, not guarantees.
Example
A 3,000 SF fast-casual restaurant in a strong trade area uses the category benchmark of $400/SF to project $1.2M in annual sales, then evaluates whether the $35/SF asking rent (8.75% occupancy cost) is sustainable.
