The arithmetic

A private at $95 generates $95 an hour. A group class of eight at $28 generates $224 for the same teaching hour, against slightly higher equipment and space cost.

Group wins on revenue per hour, which is why almost every scaled studio is group-led. Privates win on margin per client and on what they enable.

What privates are actually for

Beyond revenue, privates do two jobs a group class cannot. They onboard beginners safely, which raises group class quality and retention. And they serve clients with injuries or conditions who cannot be programmed for in a group.

A studio with no private capacity has to turn those clients away or put them in classes where they are unsafe.

The hybrid that works

Group classes at peak times, privates in the off-peak slots that would otherwise sit empty. This uses the timetable efficiently and gives teachers a fuller day.

Requiring or strongly encouraging three privates before joining group classes is common and raises retention noticeably — beginners arrive in the group knowing the machine.

When private-only makes sense

Clinical and rehabilitation-focused practices, and very small spaces where a group is not physically possible. Both are viable businesses with a lower ceiling and lower risk.

A private-only model also suits an owner-operator who does not want to manage staff — income is capped by hours, but so is complexity.
