Volunteer Retention Rate

Percentage of active volunteers from the previous period who remain engaged in the current period

What is Volunteer Retention Rate?

Volunteer retention rate is the percentage of volunteers who were active in one period who are still active in the next. It shows how well an organisation keeps its volunteers.

Recruiting and training volunteers takes effort, so keeping the ones you have is more efficient and builds experience.

(Volunteers active in both periods / Volunteers active in prior period) × 100

How to calculate it

Divide volunteers active in both periods by volunteers active in the prior period, and multiply by 100.

For example, if 300 volunteers were active last year and 210 were active this year too, retention is 70%.

Define active clearly, and look at retention by role and length of service.
