Daily, Weekly, Monthly Active Users (DAU, WAU, MAU)

Use case

We want to know the customer engagement of our store. To do this, we need to use an Active Users metric.

Data schema

Daily, weekly, and monthly active users are commonly referred to as DAU, WAU, MAU. To get these metrics, we need to use a rolling time frame to calculate a daily count of how many users interacted with the product or website in the prior day, 7 days, or 30 days. Also, we can build other metrics on top of these basic metrics. For example, the WAU to MAU ratio, which we can add by using already defined weeklyActiveUsers and monthlyActiveUsers.

To calculate daily, weekly, or monthly active users we’re going to use the rollingWindow measure parameter.

cube(`ActiveUsers`, {
  sql: `SELECT user_id, created_at FROM public.orders`,

  measures: {
    monthlyActiveUsers: {
      sql: `user_id`,
      type: `countDistinct`,
      rollingWindow: {
        trailing: `30 day`,
        offset: `start`,
      },
    },

    weeklyActiveUsers: {
      sql: `user_id`,
      type: `countDistinct`,
      rollingWindow: {
        trailing: `7 day`,
        offset: `start`,
      },
    },

    dailyActiveUsers: {
      sql: `user_id`,
      type: `countDistinct`,
      rollingWindow: {
        trailing: `1 day`,
        offset: `start`,
      },
    },

    wauToMau: {
      title: `WAU to MAU`,
      sql: `100.000 * ${weeklyActiveUsers} / NULLIF(${monthlyActiveUsers}, 0)`,
      type: `number`,
      format: `percent`,
    },
  },

  dimensions: {
    createdAt: {
      sql: `created_at`,
      type: `time`,
    },
  },
});

Query

We should set a timeDimensions with the dateRange.

curl cube:4000/cubejs-api/v1/load \
'query={
  "measures": [
    "ActiveUsers.monthlyActiveUsers",
    "ActiveUsers.weeklyActiveUsers",
    "ActiveUsers.dailyActiveUsers",
    "ActiveUsers.wauToMau"
  ],
  "timeDimensions": [
    {
      "dimension": "ActiveUsers.createdAt",
      "dateRange": [
        "2020-01-01",
        "2020-12-31"
      ]
    }
  ]
}'

Result

We got the data with our daily, weekly, and monthly active users.

{
  "data": [
    {
      "ActiveUsers.monthlyActiveUsers": "22",
      "ActiveUsers.weeklyActiveUsers": "4",
      "ActiveUsers.dailyActiveUsers": "0",
      "ActiveUsers.wauToMau": "18.1818181818181818"
    }
  ]
}
