Funnels are like multiple goals attached together. You define goals and funnels the same way. Check out our [guide to goal definition](https://docs.hockeystack.com/documentation/goals) to learn how.

For each step, HockeyStack selects the users who have done **all of the previous steps + that step.** Hovering over the step shows you this number, as well as a few other useful metrics.

* **Step Conversion Rate:** The conversion rate from the previous step to the current step. A.k.a. the percentage of users in the previous step who have also done the current step.
* **Dropoff:** The percentage of people in the previous step who have not done the current step. Can be calculated by *100 - Step Conversion Rate*
* **Funnel Conversion Rate:** The conversion rate from the first step to the current step. A.k.a. the percentage of users in the first step who have also done the current step.
* **Avg Time Since Last Action:** The time it takes for users to pass from the previous step to the current step. For product managers, optimizing this time for your "Aha Moment" funnel is crucial.

> If you have multiple similar funnels - funnels that differ by a step or two - you can duplicate a funnel and edit it in order to easily create all of your funnels.

#### Coversion Window

The Conversion Window lets you define the maximum amount of time allowed between each step in a funnel. For instance, if you're analyzing user behavior over the past year but want to focus only on users who completed all funnel steps within 1 month of each other, you can set the conversion window to 1 month.

Keep in mind that all funnel steps must still occur within the selected report date range, regardless of the conversion window. For example, if your report covers only *last month* and the conversion window is set to 3 months, the conversion window will have no effect—because all steps are already limited to the 1-month range. In this case, the funnel will only include users who completed all steps during that month.
