How we calculate
Customer lifetime value = monthly price × profit margin ÷ monthly customer loss. Cost per customer = total spend ÷ total customers. Payback period = cost per customer ÷ (price × margin). Max you should spend = lifetime value ÷ 3 (the standard 3-to-1 benchmark). Average customer lifetime (1 ÷ loss rate) is capped at 60 months, so 0% loss reads as an excellent bounded outcome rather than infinite value. In planning mode, projected customers use benchmark cost lifted by your early-stage cost increase. The projection compounds budget growth monthly, applies customer loss to the running total, and adds a gentle saturation curve on paid channels. Currency conversions are approximate.
