A flagship store on New York's Fifth Avenue can cost a brand $2,500 or more per square foot per year in rent. That is one of the most expensive retail streets on earth. So before a CFO signs the lease, one number decides everything: how many dollars of sales does each square foot actually generate?
That number is called sales per square foot, and it is the single most important productivity metric in physical retail. This lesson shows you how to compute it, what "good" looks like in the US versus Europe, and how to extend the same logic to the direct-to-consumer (DTC) channel with sales per visit. (DTC means selling straight to the shopper through your own stores and website, skipping wholesale partners like department stores.)
The formula is simple:
Sales per square foot = Annual net sales in the store / Selling area in square feet
Two traps to avoid:
A denim brand runs a flagship with 4,000 square feet of selling space. Last year it booked $8 million in net sales.
Sales per square foot = $8,000,000 / 4,000 = $2,000 per square foot.
Now the rent test. If rent is $2,500 per square foot per year, the store's entire sales output barely covers rent, let alone staff, inventory, and utilities. This store is underwater. If instead rent were $600 per square foot (a strong US mall figure), rent would be 30 percent of sales, which is high but survivable for a high-margin product.
That ratio, occupancy cost as a percentage of sales, is the second metric every fashion finance professional watches. A common rule of thumb: apparel retailers want occupancy costs (rent plus common-area charges) below roughly 15 to 20 percent of sales. Above that, the location is eating the margin.
Sales per square foot varies enormously by format and brand tier. Rough, commonly cited ranges (estimates, and they move year to year):

Two things change when you cross the Atlantic.
First, units. Europe reports in sales per square meter, not per square foot. One square meter is about 10.76 square feet. So to compare, convert:
Sales per square meter = Sales per square foot x 10.76
Our denim flagship at $2,000 per square foot equals roughly $21,500 per square meter. Do not accidentally compare a per-foot figure to a per-meter figure; you will be off by nearly 11x.
Second, format. Europe is a high-street market more than a mall market. High street means stores on traditional shopping streets (think London's Oxford Street, Paris's Champs-Elysees, Milan's Via Montenapoleone) rather than in enclosed suburban malls. High-street flagships in prime European cities carry some of the highest rents in the world, so productivity has to be extreme to justify them.
Rough European estimates (again, estimates):
The point is not memorizing exact euros. It is knowing the *two adjustments*: convert the units, and recognize you are usually comparing a high-street cost structure against a US mall cost structure.
If you compare a US chain to a European one, you must also fix the currency. A store doing 8,000 euros per square meter, at an assumed rate of 1.08 dollars per euro, is doing about 8,640 dollars per square meter, or roughly 800 dollars per square foot (8,640 / 10.76). Always state your FX (foreign exchange) rate and date.

The same productivity thinking applies online, where there is no square footage. Instead, the scarce resource is the visit (a session on the site or app). The metric is sales per visit, sometimes called revenue per visit or revenue per session.
Sales per visit = Total DTC net sales / Number of visits
It bundles two levers into one number:
Sales per visit = Conversion rate x Average order value (AOV)
An accessories brand's website gets 2,000,000 visits in a quarter and books $6,000,000 in net DTC sales.
Sales per visit = $6,000,000 / 2,000,000 = $3.00 per visit.
Now decompose it. If conversion is 2 percent, then orders = 40,000, and AOV = $6,000,000 / 40,000 = $150. Check: 0.02 x $150 = $3.00. It ties out.
Why decompose? Because it tells you *which* lever to pull. Fashion e-commerce conversion rates are commonly cited in the low single digits (often around 1.5 to 3 percent, an estimate that varies by brand and traffic quality). If your conversion is already healthy but sales per visit is weak, the problem is AOV: bundle products, raise the free-shipping threshold, cross-sell. If AOV is fine but conversion is low, the problem is the funnelfunnelThe customer journey from awareness to purchase, typically Awareness, Interest, Consideration, Decision, Action, with prospects narrowing at each stage.Voir la définition complète →: site speed, product pages, checkout friction.

A modern fashion CFO does not treat stores and DTC as separate worlds. Both answer the same question: is each unit of the scarce resource earning enough?

Return to the flagship. Sales per square foot of $2,000 sounded impressive until we compared it to $2,500 rent. Context is everything:
So a flagship can be "unprofitable" on sales per square foot yet still be justified, but only if leadership explicitly treats it as marketing spend (brand visibility, tourist reachreachThe number of unique people exposed to your message in a given period.

That is a deliberate decision, and it should be stated in the numbers, not hidden.
