Lifetime value when the product costs less than a coffee

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.

The standard SaaS LTVLTVLifetime Value: the total revenue (or profit) a customer generates throughout their entire relationship with your business.Voir la définition complète → 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.

• Purchase frequency: how often the category is bought (e.g., laundry detergent roughly every 4 to 8 weeks per US household, estimate)
• Basket share / share of requirements: what percentage of that category's purchases go to your brand versus rivals
• Repeat purchase rate: the probability a buyer repurchases the brand next cycle, instead of switching

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):

• Household annual spend on laundry detergent: ~$70/year
• Your brand's share of requirements (basket share) for a loyal-leaning household: 60%
• 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 → on detergent (typical CPG estimate): ~45%
• Average relationship length before a household fully switches away or the buyer ages out of the category: 8 years

Calculation:

Compare that to the item price of maybe $6 a bottle. The single-purchase view radically understates value.

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.Voir la définition complète → 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.Voir la définition complète →.

Repeat purchase rate: the number that actually moves LTVLTVLifetime Value: the total revenue (or profit) a customer generates throughout their entire relationship with your business.Voir la définition complète →

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):

• Packaged food/snacks: 30 to 45% repeat rate within a 12-week window is often considered healthy for a newer brand
• Household cleaning: higher habitual repeat, sometimes 50%+, because switching costs (in attention, not cash) are high once a routine forms
• Premium/novelty categories (specialty snacks, new beverage lines): often below 20%, which is why so many CPG launches fail to scale past trial

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.Voir la définition complète →" 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.

A quick sanity-check framework

Before trusting any FMCG LTVLTVLifetime Value: the total revenue (or profit) a customer generates throughout their entire relationship with your business.Voir la définition complète → number, ask:

1. What time horizon am I using? Category life stage matters (diapers: 2-3 years; laundry detergent: decades).

2. Is basket share from a real panel (Kantar, Circana/IRI, Nielsen) or guessed? Never invent a share number, always cite the panel source.

3. Am I calculating per household or per shopper? Multi-person households distort per-person LTVLTVLifetime Value: the total revenue (or profit) a customer generates throughout their entire relationship with your business.Voir la définition complète → upward if you're not careful.

4. Does gross margin reflect trade spend?
