How it works
Retention rate is the share of the patients you started with who are still active at the end. New patients are taken out, because they were not there at the start.
- Retention rate = (patients at the end - new patients) / patients at the start x 100
- Churn rate = 100 - retention rate
Worked example
A brand started the month with 2,400 active patients and ended with 2,650, of whom 540 joined during the month.
| Step | Calculation | Result |
|---|---|---|
| Retention rate | (2,650 - 540) / 2,400 | 87.9% |

Telehealth notes
- Patients on a pause are still patients until the pause ends without a restart.
- Compare retention by the angle or channel that brought patients in. Some angles attract patients who stay longer.
Questions
How do you calculate retention rate?
Take patients at the end of the period, subtract the new ones, divide by patients at the start and multiply by 100.
Is retention the opposite of churn?
Yes. Over the same period they add up to 100.
