How this calculator works
CPA = ad spend / conversions; conversion = customers / visitors; ROAS = revenue / ad spend; LTV = average revenue/customer × margin × repeats × customer lifespan.
Important assumptions
LTV uses the simplified revenue per customer × gross margin × purchases per year × customer lifetime. Enter revenue for the observed acquisition cohort and make cohort assumptions explicit. No discounting or retention curve modelled.
