# Fictional example output | Cohort | Common observed horizon | Net revenue / acquired customer | CAC | Observed revenue-to-CAC ratio | Repeat-customer fraction | | --- | ---: | ---: | ---: | ---: | ---: | | June | 60 days | $8,000/100 = $80 | $3,000/100 = $30 | 2.6667 | 50/100 = 50.00% | | July | 60 days | $7,000/100 = $70 | $3,000/100 = $30 | 2.3333 | 40/100 = 40.00% | July's observed 60-day revenue per acquired customer is $10 lower (−12.50%). June's $9,000 at 90 days must not be compared with July's $7,000 at 60 days as equal-horizon lifetime value. This is observed 60-day value, not a lifetime forecast or profit LTV; CAC ratios do not include service/product costs. Membership and elapsed maturity are supported by the fictional export guarantee. Without per-customer age coverage in an actual export, alignment would remain unverified. Next: compare acquisition mix, offers, returns and repeat ordering at the same horizon. No projected lifetime multiple, payback date, or bid-target change was invented.
