A single bottle of laundry detergent sells for less than a latte.

Because that shopper doesn't buy one bottle. She buys detergent every six weeks for the next fifteen years, and she's also deciding which shampoo, dish soap and diaper brand her household defaults to. In FMCG (fast-moving consumer goods: low-cost, high-frequency products like packaged food, toiletries and household cleaners), LTVLTVLifetime Value: the total revenue (or profit) a customer generates throughout their entire relationship with your business.View full definition → isn't about one transaction. It's about owning a repeat habit inside a household's shopping cart, permanently.
The standard SaaS LTVLTVLifetime Value: the total revenue (or profit) a customer generates throughout their entire relationship with your business.View full definition → formula is clean:
LTV = (Average Revenue per Account × Gross Margin %) / Churn Rate
That works when there's one contract, one renewal date, one clear "cancel" event. FMCG has none of these. There's no login to cancel. A shopper doesn't "churn," she just quietly starts buying a competitor's brand on 30% of trips while still buying yours the rest of the time.

A practical version used across CPG (consumer packaged goods) marketing teams:
LTV = (Annual Category Spend per Household × Brand's Share of Requirements × Gross Margin %) × Average Relationship Length (years)
Let's worked-example this with realistic, clearly-labeled estimates.
Inputs (illustrative, US market, 2025-2026 estimate):
Calculation:
Annual brand revenue per household = $70 × 60% = $42
Annual brand profit per household = $42 × 45% = $18.90
LTV (8-year horizon) = $18.90 × 8 = $151.20Compare that to the item price of maybe $6 a bottle. The single-purchase view radically understates value. That $151 number is what justifies a customer acquisition costcustomer acquisition costCustomer Acquisition Cost (CAC) is the total sales and marketing spend divided by the number of new customers gained in a period.

Here's the twist that's specific to this sector: the buying unit is rarely one person. It's a household, and household composition changes.
A shopper who is loyal to a diaper brand has an LTVLTVLifetime Value: the total revenue (or profit) a customer generates throughout their entire relationship with your business.View full definition → horizon capped by how long her child is in diapers (roughly 2 to 3 years).

It's also why "basket share" data from loyalty cards (Kroger's 84.51°, Tesco Clubcard) is more strategically valuable than raw unit sales: it tells you what portion of a household's total category spend you're capturing, which is the real driver of LTVLTVLifetime Value: the total revenue (or profit) a customer generates throughout their entire relationship with your business.View full definition →.
Of the three levers, repeat purchase rate is the one marketing can influence fastest and the one most FMCG dashboards track weekly.
Typical benchmarks (industry estimates, vary hugely by category and are not official published standards):
A useful diagnostic ratio marketers use:
Repeat Rate = Buyers who purchase a 2nd time within period / Total first-time (trial) buyers
If trial is strong (say, a sampling campaign converts well) but repeat rate is weak, the problem isn't awareness, it's product experience or price/pack mismatch. This is a much more actionable signal than "conversion rateconversion rateThe percentage of visitors or prospects who complete a desired action (purchase, sign-up, contact form), calculated as conversions divided by total opportunities.View full definition →" borrowed from ecommerce funnels.
For deeper category-level repeat purchase and penetration data, Kantar's Worldpanel division publishes methodology notes and reports that are the industry reference for these numbers.
