# Order Retention

*This report differentiates from the* [*Customer Retention*](/using-the-web-app/reports/cohort-analysis/customer-retention.md) *report by calculating a ratio of orders within an interval since first purchase (e.g. Month 1) divided by the number of orders that were made within the first interval since first purchase (e.g. Month 0). In contrast, Customer Retention does not display the impact of multiple orders, but instead shows the proportion of the originally acquired customers that are making returning purchases over time.*

*Since Day 0, Week 0 and Month 0 will always be 100%, they have been excluded from this report to allow the focus to be on the following periods.*

*For example, let's assume we're looking at Subscription as a Segment and the cohort of Jan. 2020. There were 10,000 orders of the Subscription in Jan. 2020 by customers acquired in the same month. In Feb. 2020 (Month 1), customers acquired in Jan. 2020 made 3,000 orders of the Subscription Segment. The order retention reflected is 3,000 / 10,000 = 30%.*&#x20;

*Order retention is simply a ratio and does not require that the 3,000 orders came from the same customers that made the 10,000 orders. In fact, it's possible some of those customers went on to purchase NonSubscription in Feb. 2020, but that would not be reflected in the order retention because we're purely looking at the Order Retention of the Subscription Segment.*

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.drivepoint.io/using-the-web-app/reports/cohort-analysis/order-retention.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
Metric/Dimension	Definition
Order Retention	Cohorted by when they made their first purchase (Cohort Interval), the number of returning orders divided by the number of orders from the cohort (Cohort Size) in the first interval (e.g. Month 0). For example, Month 1 retention reflects the number of orders in Month 1 from customers acquired in the same Cohort Interval divided by the number of orders that the same cohort made in Month 0.
Cohort Interval	This is a control available in the Filters menu with the possible options of Quarter, Month, Week, and Day. Each option groups first-time customers together into cohorts based on the interval selected. For instance, a customer that makes their first purchase on January 15th, 2024 is cohorted into Q1 2024 (quarter), Jan-24 (month), (week of) Jan 14, 2024, and Jan 15, 2024 (day).
Interval Since First Purchase	This is a control available in the Filters menu with the possible options of Month, Week, and Day. Each option calculates the calendar distance since the first purchase.
Segment	Unlike the Customer Retention report where customers are completely segmented by the first segment (e.g. Subscription) they purchase, this defines the segment that was actually purchased on both the numerator and the denominator of the Order Retention formula.
