Fitness club premium membership penetration measures the percentage of recurring billing members enrolled in a higher-priced membership tier.
Planet Fitness reported 66.5% PF Black Card penetration at December 31, 2025, up from 63.9% a year earlier and 62.6% at the end of 2021.
Premium penetration is a mix metric
PF Black Card members pay higher monthly dues than Classic Card members and receive additional benefits such as system-wide club access, guest privileges, and premium in-club amenities.
A higher penetration rate can therefore lift average monthly dues per member even if total membership is unchanged.
The percentage uses recurring billing members
Planet Fitness defines the metric as PF Black Card recurring billing members divided by the total recurring billing membership base.
It is not the share of revenue generated by premium memberships and should not be applied directly to total company revenue.
Mix growth can interact with pricing changes
Average monthly dues reached $19.51 by the end of 2025 while PF Black Card penetration also increased.
Because the company also changed Classic Card pricing, investors should treat dues growth as a combined price-and-mix outcome rather than attributing it entirely to premium conversion.
