While dimensions describe attributes of individual rows, measures compute values across rows — sums, counts, averages, and other aggregations. Measures can aggregate columns directly (like sum of revenue) or reference other measures to create compound metrics (like revenue / count).
See the measures reference for the full list of parameters and configuration options.

​
Defining measures

A measure specifies the SQL expression to aggregate and the aggregation type: 
cubes:
  - name: orders
    sql_table: orders

    measures:
      - name: count
        type: count

      - name: total_amount
        sql: amount
        type: sum

      - name: average_amount
        sql: amount
        type: avg

​
Filtered measures

You can apply filters to a measure to create conditional aggregations. Only rows matching the filter are included: 
cubes:
  - name: orders
    # ...

    measures:
      - name: count
        type: count

      - name: completed_count
        type: count
        filters:
          - sql: "{CUBE}.status = 'completed'"
When completed_count is queried, Cube generates SQL with a CASE expression: 
SELECT
  COUNT(CASE WHEN (orders.status = 'completed') THEN 1 END) AS completed_count
FROM orders

​
Calculated measures

Calculated measures perform calculations on other measures using SQL functions and operators. They provide a way to decompose complex metrics (e.g., ratios or percents) into formulas involving simpler measures.

​
Referencing measures in the same cube

cubes:
  - name: orders
    # ...

    measures:
      - name: count
        type: count

      - name: completed_count
        type: count
        filters:
          - sql: "{CUBE}.status = 'completed'"

      - name: completed_ratio
        sql: "1.0 * {completed_count} / NULLIF({count}, 0)"
        type: number

​
Referencing measures from other cubes

If cubes are joined, you can reference measures across cubes. Cube generates the necessary joins automatically: 
cubes:
  - name: users
    # ...

    joins:
      - name: orders
        sql: "{CUBE}.id = {orders}.user_id"
        relationship: one_to_many

    measures:
      - name: count
        type: count

      - name: purchases_to_users_ratio
        sql: "1.0 * {orders.purchases} / NULLIF({CUBE.count}, 0)"
        type: number

​
Multi-stage measures

Multi-stage measures are calculated in two or more stages, enabling calculations on already-aggregated data. Each stage results in one or more CTEs in the generated SQL query.
Multi-stage measures are powered by Tesseract, the next-generation data modeling engine. Tesseract is currently in preview. Use the CUBEJS_TESSERACT_SQL_PLANNER environment variable to enable it.

​
Rolling windows

Rolling window measures calculate metrics over a moving window of time, such as cumulative counts or moving averages. Use the rolling_window parameter: 
measures:
  - name: cumulative_count
    type: count
    rolling_window:
      trailing: unbounded

  - name: trailing_month_count
    sql: id
    type: count
    rolling_window:
      trailing: 1 month

​
Period-to-date

Period-to-date measures analyze data from the start of a period to the current date — year-to-date (YTD), quarter-to-date (QTD), or month-to-date (MTD): 
measures:
  - name: revenue_ytd
    sql: revenue
    type: sum
    rolling_window:
      type: to_date
      granularity: year

  - name: revenue_qtd
    sql: revenue
    type: sum
    rolling_window:
      type: to_date
      granularity: quarter

​
Time shift

Time-shift measures calculate the value of another measure at a different point in time, typically for period-over-period comparisons like year-over-year growth. Use the time_shift parameter: 
measures:
  - name: revenue
    sql: revenue
    type: sum

  - name: revenue_prior_year
    multi_stage: true
    sql: "{revenue}"
    type: number
    time_shift:
      - interval: 1 year
        type: prior
You can combine time shift with period-to-date for comparisons like “this year’s YTD vs. last year’s YTD”: 
measures:
  - name: revenue_ytd
    sql: revenue
    type: sum
    rolling_window:
      type: to_date
      granularity: year

  - name: revenue_prior_year_ytd
    multi_stage: true
    sql: "{revenue_ytd}"
    type: number
    time_shift:
      - time_dimension: time
        interval: 1 year
        type: prior
Time-shift measures can also be used with calendar cubes to customize how time-shifting works, e.g., to shift by retail calendar periods.

​
Percent of total (fixed dimension)

Use the group_by parameter to fix the inner aggregation to specific dimensions, enabling percent-of-total calculations: 
measures:
  - name: revenue
    sql: revenue
    type: sum

  - name: country_revenue
    multi_stage: true
    sql: "{revenue}"
    type: sum
    group_by:
      - country

  - name: country_revenue_percentage
    multi_stage: true
    sql: "{revenue} / NULLIF({country_revenue}, 0)"
    type: number

​
Nested aggregates

Use the add_group_by parameter to compute an aggregate of an aggregate, e.g., the average of per-customer averages: 
measures:
  - name: avg_order_value
    sql: amount
    type: avg

  - name: avg_customer_order_value
    multi_stage: true
    sql: "{avg_order_value}"
    type: avg
    add_group_by:
      - customer_id

​
Ranking

Use the reduce_by parameter to rank items within groups: 
measures:
  - name: revenue
    sql: revenue
    type: sum

  - name: product_rank
    multi_stage: true
    order_by:
      - sql: "{revenue}"
        dir: asc
    reduce_by:
      - product
    type: rank

​
Conditional measures

Conditional measures depend on the value of a dimension, using the case parameter with switch dimensions: 
measures:
  - name: amount_in_currency
    multi_stage: true
    case:
      switch: "{CUBE.currency}"
      when:
        - value: EUR
          sql: "{CUBE.amount_eur}"
        - value: GBP
          sql: "{CUBE.amount_gbp}"
      else:
        sql: "{CUBE.amount_usd}"
    type: number

​
Formatting

Use the format parameter to control how measures are displayed: 
measures:
  - name: total_revenue
    sql: revenue
    type: sum
    format: currency

  - name: conversion_rate
    sql: "1.0 * {completed_count} / NULLIF({count}, 0)"
    type: number
    format: percent
