Sales and earnings
Shares figures RockBox Fitness publishes sales or earnings figures for its locations. The full tables, with notes on which locations are counted, are in its filing.
- Average net sales
- $316,310
Yearly figures for 2024, covering franchised studios open all of 2024 (48 locations). The filing gives an average for each performance group rather than one overall figure; this is the overall average worked out from those and each one's number of locations. The average is about 0.6 times the midpoint of the cost to open.
Sales are what a location takes in before rent, payroll, royalties and other costs, not what its owner keeps.
