Free Customer Lifetime Value Calculator

How this tool computes its result

Computes total revenue per customer as average order value × purchase frequency (entered as "per year") × customer lifespan (entered in months), then applies profit margin: CLV = totalRevenue × (profitMargin / 100). A rule-based recommendation list layers independent tips based on CLV bands (<0, <50, <200, <500, ≥500), purchase frequency thresholds (<2 low, ≥4 high), lifespan thresholds (<12 short, ≥24 long), and margin (<20% low) — multiple tips can fire simultaneously since none of these checks are mutually exclusive.

Worked example

With average order value $50, purchase frequency 4/year, customer lifespan 24 months, and profit margin 30%: totalRevenue = 50 × 4 × 24 = $4,800, and CLV = 4,800 × 0.30 = $1,440. Because purchase frequency (entered per year) is multiplied directly by lifespan (entered in months) with no unit conversion between the two, this total-revenue figure is roughly 12× higher than a standard annual-frequency × annual-lifespan model would produce — the equivalent standard-model total would use lifespan in years (24 months = 2 years): 50 × 4 × 2 = $400.

When not to use this tool

The formula has no discounting for the time value of money and assumes AOV, frequency, and margin all stay constant for the entire customer lifespan with no cohort decay — it isn't built for a discounted CLV figure used in finance or board reporting.

Common mistakes

• - Entering customer lifespan in months exactly as the field is labeled while purchase frequency stays "per year" — the formula multiplies the two directly without converting months to years, inflating CLV roughly 12× versus the standard annual model; divide your lifespan by 12 before entering it if you want a conventional annual CLV figure.
• - Leaving any one of AOV, frequency, lifespan, or margin at exactly 0 — the tool requires all four to be non-zero before it will show a result at all, so a single blank field suppresses the entire output rather than computing a partial result.
• - Treating the recommendation list as prioritized — CLV-band, frequency, lifespan, and margin tips are all appended independently, so a genuinely healthy CLV can still surface three or four tips at once with no ranking of which matters most.
