Cost per Onboarding

Cost per Onboarding: Total onboarding cost divided by customers onboarded.

Formula

Cost per Onboarding = Total onboarding team cost / Customers onboarded

Computable definition

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

sum(field.cost where field.cost_function = 'onboarding') / count_distinct(field.onboarding_id where in_period(field.onboarding_completion_date))

Unit: currency

Data requirements

Grain: Per event · Frequency: Per onboarding · Aggregation: event · Staged: no · Main source: Finance / ERP.

Field	Dataset	Type
`cost`	cost_event	decimal
`cost_function`	cost_event	string
`event_date`	cost_event	date
`onboarding_completion_date`	onboarding	date
`onboarding_id`	onboarding	string
`snapshot_date`	onboarding	date

Example SQL (Postgres)

SELECT (CAST((SELECT COALESCE(SUM(cost), 0) FROM cost_event WHERE event_date >= :period_start AND event_date <= :period_end AND cost_function = 'onboarding') AS DOUBLE PRECISION) / NULLIF((SELECT COUNT(DISTINCT onboarding_id) FROM onboarding WHERE snapshot_date = :period_end AND (onboarding_completion_date >= :period_start AND onboarding_completion_date <= :period_end)), 0)) AS cost_per_onboarding

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