Fitness club net member growth measures the change in total members over a reporting period after joins, cancellations, transfers, and other membership changes.
Planet Fitness added approximately 1.1 million net new members during 2025.
Planet Fitness deliberately does not foreground attrition
The company records membership changes daily through its point-of-sale system and monitors membership growth, average members per club, average monthly dues, and transfers between locations.
Planet Fitness explicitly says it does not rely on membership attrition as a separate operating metric when assessing performance.
That makes net member growth a more central public measure than a standalone churn statistic.
Growth comes from existing clubs and new clubs
Planet Fitness says member growth is driven by both net member growth at existing clubs and expansion of the system-wide club base.
Those are different engines. Mature-club member gains support same-club sales, while new club openings create entirely new membership capacity.
Net growth does not reveal gross joins or cancellations
A positive net number can result from many combinations of additions and losses.
Use net member growth to understand the direction and magnitude of the membership base, but avoid treating it as a retention rate or gross acquisition measure.
