Sales Per Square Foot Formula
The calculator uses sales per square foot as the base measure. If you enter square meters or dollars per square meter, it converts those values before calculating the missing field.
- SPSF = sales per square foot, in dollars per square foot
- SPSM = sales per square meter, in dollars per square meter
- TSS = total store sales, in dollars
- A = total store area, usually in square feet
- Aft² = area in square feet
- Am² = area in square meters
Choose Sales per area to divide total store sales by store area.
Choose Total store sales to multiply store area by sales per area.
Choose Store area to divide total store sales by a positive sales rate. Enter the known values and select Calculate.
Area and rate unit changes preserve the entered quantity. Rate and area results show both square-foot and square-meter equivalents.

FAQ
What does sales per square foot mean?
Sales per square foot measures how much revenue a store generates for each square foot of space. It is commonly used to compare store productivity, evaluate layout efficiency, and compare locations of different sizes.
Should storage rooms and offices be included in total store area?
Use the same area definition each time you compare results. If you want to measure the productivity of customer-facing selling space, use only the sales floor. If you want to measure the productivity of the full leased space, include storage, offices, and back-of-house areas.
Is a higher sales per square foot always better?
Not always. A higher value usually means the space is producing more revenue, but it does not show profit, rent cost, labor cost, or inventory cost. Use it with margin and expense data before making business decisions.
