What it is: N-Day LTV brings cumulative revenue measurement to Retention Analysis, so you can track how much value a cohort generates across fixed day windows: Day 1, Day 7, Day 14, Day 30. To use it, set a start event, pick a revenue return event, and toggle N-Day LTV under the Return Event controls. The chart breaks down revenue by day window, with options for all users or paying users only, period comparison, and 24-hour or calendar-day windows. Before this, teams that needed LTV analysis had to export data and build charts in external tools, pulling analysts out of Amplitude and requiring manual upkeep.
