# Ancillary Revenue Mix

Dues pay for the room. **The margin lives in ancillary**: personal training, small-group/semi-private, retail, and café. The metric is revenue (and contribution margin) **per member**, and it rides on retention — you can't sell PT to a member who already quit.

## The lines and where their margin sits

| Line | Margin character | Attach lever |
|---|---|---|
| Personal training / semi-private | High-margin labor; premium to dues | Assessment at onboarding; goal-driven upsell |
| Retail (apparel, supplements, gear) | Merchandise margin; inventory risk | POS attach, curated assortment |
| Café / juice bar / smoothies | Food-service margin + traffic | Pre/post-class impulse; throughput |
| Workshops / challenges / events | Programmed high-margin bursts | Community + referral engine |

## The measure

```
ancillary revenue per member   =  total ancillary revenue / active members
ancillary attach rate          =  members who buy ancillary / active members
```

Model these **before** touching dues pricing — a modest lift in PT attach often beats a risky dues increase. Attach and margin norms are `[verify-at-use]`.

## Sequencing rule

Ancillary rides on retention and onboarding:

```
weak retention?  -> fix retention first (churned members buy nothing)
strong retention, low PT attach?  -> build the onboarding assessment -> PT path
strong PT, no retail/café?  -> add the highest-margin, lowest-ops line that fits your space
```

## Anti-patterns

- Chasing dues increases while PT/retail attach sits untapped.
- Adding a café or retail line before the membership base is retained enough to buy from it.
- Measuring ancillary in gross dollars instead of per-member and by contribution margin (a busy café at thin margin can lose money).
