## Adding Event cost and Event processing time

:::note
**Event cost** are the costs for executing the event. **Event processing time** is defined as the amount of time actually spent working for the event.
:::

Automation estimate rates in the **Efficiency - Automation** dashboard are calculated by the `Event cost` and the `Event processing time` expressions in the `Events_base` table in the Discovery Accelerator. In order to display these values in the **Efficiency - Automation** dashboard you must define the expressions used to calculate the values.

See illustration below.
