Contraction MRR: MRR reduction from existing customers who downgraded but didn't churn.
Formula
Contraction MRR = Sum of (MRR decrease from existing customers who remain active)Computable definition
The canonical formula in the GASP formula grammar. The MCP server compiles it to SQL over the datasets listed below.
-sum(field.mrr_change where field.event_type = 'contraction')Unit: currency
Breakdowns
by_segment: one row persegmentvalue
Notes: Contraction events carry a negative mrr_change; the metric reports a positive amount. by_segment returns one row per customer segment, so downgrades concentrated in one segment are visible.
Data requirements
Grain: Per event, aggregate monthly · Frequency: Daily sync · Aggregation: aggregate (month) · Staged: no · Main source: Billing.
| Field | Dataset | Type |
|---|---|---|
event_date | revenue_event | date |
event_type | revenue_event | string |
mrr_change | revenue_event | decimal |
Example SQL (Postgres)
SELECT (-(SELECT COALESCE(SUM(mrr_change), 0) FROM revenue_event WHERE event_date >= :period_start AND event_date <= :period_end AND event_type = 'contraction')) AS contraction_mrr Access: recommended
