# Speak the language: the acronyms that run every retail meeting
A CFO opens a Q3 earnings call: "LFL was up 3.2%, GMV grew 11%, but AUR softened and we ended the quarter with tighter OTB." Nobody blinks. If you don't know what any of those letters mean, you've lost the thread before slide two. Retail runs on acronyms the way finance runs on ratios, and this lesson gives you the working vocabulary to sit in that meeting and actually follow it.
The growth headline: LFL / SSS / comp
The single most-watched number in retail is like-for-like sales (LFL), also called same-store sales (SSS) in the US or simply "comp" (comparable sales).
Definition: revenue growth from stores/channels open for at least 12 months, stripping out the effect of new store openings or closures. It answers: "are existing operations getting healthier, or is growth just coming from opening more boxes?"
Worked example: a chain has $500m total revenue this year vs. $440m last year (+13.6%). But $50m of this year's revenue comes from 20 new stores opened mid-year. LFL sales = ($500m - $50m) / $440m... actually the cleaner way: compare only the stores that existed in both periods.
Comparable-store revenue this year: $450m
Same stores last year: $440m
LFL = (450, 440) / 440 = +2.3%
That 2.3% is the number analysts care about. The 13.6% headline growth is mostly "we opened stores," which is a different story (expansion, not productivity).
As of 2025/2026, US retail LFL growth for established chains has generally run in the low-single digits (estimate, varies hugely by category); European grocers and value retailers have often printed slightly higher LFL due to food inflation passthrough (estimate).
Volume vs. value: GMV, revenue, and the marketplace trap
GMV (Gross Merchandise Value): the total value of goods sold through a platform, before deducting fees, returns, or the marketplace's own cut. Amazon, Zalando, and Etsy all report GMV because a large share of their sales happens through third-party sellers.
The trap: GMV is not revenue. If Zalando's GMV is €14bn but it only takes a ~20-30% commission on third-party sales (illustrative range, varies by category), its recognized revenue is much smaller. Always ask: "is this GMV or net revenue?" before comparing two companies' size.
Pricing and merchandising: AUR, ASP, sell-through
AUR (Average Unit Retail): the average selling price per unit sold, after markdowns. A fashion retailer tracking AUR decline quarter over quarter is telling you it's discounting more to move stock.
ASP (Average Selling Price): used more broadly (electronics, appliances, any category), same logic: total revenue / units sold.
Sell-through rate: % of stocked units actually sold in a period. Low sell-through = inventory risk building up, usually followed by markdowns.
Quick calc: a retailer buys 10,000 units of a jacket, sells 7,500 in the season. Sell-through = 7,500/10,000 = 75%. Anything meaningfully below 70-80% (rule of thumb, category-dependent) usually triggers markdown planning.
Buying and inventory control: OTB, WOS, GMROI
OTB (Open-To-Buy): the budget a buyer still has left to spend, calculated as planned purchases minus what's already committed. It's the buying team's checkbook. "We're tight on OTB for Q2" means the buyer has little room left to place new orders without exceeding the inventory/sales plan.
WOS (Weeks of Supply): current inventory divided by average weekly sales rate. Tells you how many weeks current stock will last at the current sell rate. Too high = overstocked, cash tied up; too low = stockout risk.
GMROI (Gross Margin Return on Inventory Investment): gross margingross marginGross margin is the share of revenue left after subtracting the direct cost of producing goods or services, expressed as a percentage of revenue.Voir la définition complète → dollars earned per dollar of average inventory invested. Formula: Gross MarginGross MarginGross margin is the share of revenue left after subtracting the direct cost of producing goods or services, expressed as a percentage of revenue.Voir la définition complète → $ / Average Inventory Cost. A GMROI above 1.0 to 2.0+ depending on category generally signals the inventory is earning its keep; retail finance teams use it to compare category profitability, not just margin %.
These three acronyms are how merchandising and finance talk to each other without a shared P&L in front of them.
Space and productivity: sq ft / sq m, sales density
US retailers report sales per square foot; European retailers report sales per square metre (1 sq m ≈ 10.76 sq ft, so divide the US figure by ~10.8 to compare, roughly).
This is the core productivity metric for physical stores; declining sales density is often the earliest warning sign of a format losing relevance, well before profit numbers move.
Estimate context: well-performing specialty retail in the US commonly targets several hundred dollars per sq ft annually, with grocery and convenience running higher due to fast turnover; these figures vary enormously by category and should always be checked against the specific segment (source for methodology: NRF's State of Retail resources).
Market size anchors (2025/2026, estimates)
To sound fluent, know rough scale:
US retail sales: roughly $5.5 to $5.8 trillion annually including autos and fuel (estimate, US Census Bureau data, census.gov/retail).
E-commerce share of US retail: roughly 16 to 17% of total retail sales (estimate, US Census).
EU27 retail trade turnover: broadly comparable in scale when converted, with e-commerce penetration varying widely by country (Nordics and UK higher, Southern/Eastern Europe lower); reference Eurostat retail trade statistics.
UK specifically often cited with one of the highest online retail penetration rates in Europe (estimate, ONS data).
Always treat these as directional. Definitions differ (some include auto/fuel, some don't), so cross-source figures carefully before quoting them in a real deck.
Vérification des acquis
1. Why do analysts care more about LFL/SSS growth than total headline revenue growth?
2. A retailer's total revenue grew 13.6% year-over-year, but LFL sales grew only 2.3%. What does this gap most likely indicate?
3. A company reports strong GMV growth on its marketplace platform. Why should this figure be interpreted with caution compared to revenue?

Digital and loyalty acronyms you'll hear constantly
CAC (Customer Acquisition Cost): marketing spend to acquire one new customer. Retail's version of a north-star cost metric for e-commerce and DTC (Direct-to-Consumer) brands.
LTV / CLV (Customer Lifetime Value): projected total profit from a customer over the relationship. The CACCACCustomer Acquisition Cost (CAC) is the total sales and marketing spend divided by the number of new customers gained in a period. It measures how efficiently you grow.Voir la définition complète →:LTVLTVLifetime Value: the total revenue (or profit) a customer generates throughout their entire relationship with your business.Voir la définition complète → ratio is the classic DTC sanity check; ratios below roughly 1:3 are often flagged as concerning (estimate/rule of thumb, not universal).

Due diligence: quick checks before you trust a number
When a number appears in a deck or call, run these checks fast:
1. LFL basis: constant currency or reported? Currency swings can flatter or flatter international retailers' headline growth.
2. Store count changes: is the LFL calculation window adjusted for closures (common in restructuring years)?
3. GMV vs. net revenue: for any marketplace or platform business, always ask which one is being quoted.
4. Calendar effects: 52-week vs. 53-week fiscal years, and shifting holiday timing (Easter, Chinese New Year) distort quarter-over-quarter comparisons.
5. Definitional drift: "digital sales" sometimes includes app-influenced in-store purchases, not just e-commerce transactions. Ask what's included.

Key Takeaways
LFL/SSS/comp measures organic health of existing stores; always separate it from total revenue growth driven by new openings.
GMV is not revenue: critical distinction for any marketplace or platform business (Amazon, Zalando, Etsy).
AUR, sell-through, WOS, and GMROI are the merchandising toolkit for tracking pricing power and inventory risk; a sell-through rate meaningfully below 70-80% usually signals coming markdowns.
OTB is the buyer's remaining budget; tight OTB commentary on a call signals inventory discipline or cash constraints.
Treat every headline figure (US retail size, e-commerce penetration, sales density) as an estimate tied to a specific definition and date; always check the source (Census Bureau, Eurostat, NRF) before quoting it externally.
