Retention rate意思

"Retention rate" is a term used in various contexts, but it typically refers to the percentage of individuals or items that remain in a particular group over a specific period. It is often used to measure customer loyalty, employee retention, or the ability of a company, product, or service to keep users or customers over time.

For example:

In all these cases, the retention rate is calculated by dividing the number of individuals who have remained in the group by the total number of individuals who were in the group at the start of the period, and then multiplying by 100 to express it as a percentage.
