Baseline case
A customer spends $50 per order, four times a year, stays three years, at a 60% gross margin and $100 to acquire.
Annual value per customer is $200, giving a gross CLV of $600 over three years. The margin-adjusted CLV (the part you actually keep) is $360, a 3.6 LTV:CAC ratio against the $100 acquisition cost, with payback in 10 months.

Always work from the margin-adjusted $360, not the $600 headline. A 3.6 ratio clears the healthy 3.0 bar, so this customer is worth acquiring at $100.

Higher order value
Lift the average order to $60 while keeping frequency, lifespan, margin, and cost fixed.
Gross CLV rises to $720 and margin-adjusted CLV to $432, lifting the LTV:CAC ratio to 4.32 and shortening payback to 8.3 months.

A 20% bigger basket flowed straight through to value because frequency and lifespan were unchanged. Upselling order size is one of the cleanest ways to improve unit economics.

Lower purchase frequency
Customers buy only three times a year instead of four, with everything else at baseline.
Gross CLV falls to $450 and margin-adjusted CLV to $270, dropping the LTV:CAC ratio to 2.7 and stretching payback to 13.3 months.

Losing one order a year pushed the ratio below the healthy 3.0 line. Frequency compounds across the whole lifespan, so a small dip in repeat rate quietly undermines acquisition math.

Longer customer lifespan
Retention improves so customers stay four years rather than three, holding the other inputs steady.
Gross CLV climbs to $800 and margin-adjusted CLV to $480, raising the LTV:CAC ratio to 4.8 while payback stays at 10 months.

An extra retained year added $120 of kept margin without changing payback, since the cost is recovered in the early months. Retention extends the profitable tail, the cheapest growth there is.
