Product Retention Metrics (Product) Operational

Resurrection Rate

Resurrection Rate: Percentage of users dormant at period start who returned in the period.

Formula

Resurrection Rate = Reactivated users / Dormant users × 100

Computable definition

The canonical formula in the GASP formula grammar. The MCP server compiles it to SQL over the datasets listed below.

count_distinct(field.user_id where field.product_event_type = 'reactivation') / count_distinct(field.user_id where field.user_status = 'dormant') at period_start

Unit: percent (the formula yields an unscaled ratio)

Data requirements

Grain: Per event, aggregate monthly · Frequency: Daily · Aggregation: aggregate (month) · Staged: no · Main source: Product Analytics.

Field	Dataset	Type
`event_date`	product_event	date
`product_event_type`	product_event	string
`snapshot_date`	user	date
`user_id`	product_event	string
`user_id`	user	string
`user_status`	user	string

Example SQL (Postgres)

SELECT (CAST((SELECT COUNT(DISTINCT user_id) FROM product_event WHERE event_date >= :period_start AND event_date <= :period_end AND product_event_type = 'reactivation') AS DOUBLE PRECISION) / NULLIF((SELECT COUNT(DISTINCT user_id) FROM user WHERE snapshot_date = :period_start AND user_status = 'dormant'), 0)) AS resurrection_rate

From an agent: with the GASP MCP server, call lookup_metric({ "name": "Resurrection Rate" }) or generate_query({ "metric": "Resurrection Rate", "adapter": "<your adapter JSON>" }).

What It Tells You

How many lapsed users you win back.
